* regex.scm (fold-matches, list-matches): New functions.

[bpt/guile.git] / ice-9 / ChangeLog

1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>

        * regex.scm (fold-matches, list-matches): New functions.
        (regexp-substitute/global): Rewritten again in terms of
        list-matches, to get null match behavior correct.

        * regex.scm (regexp-substitute/global): Rewrite so that 'post at
        the end of the item list actually causes a tail call.  (Thanks to
        Jan Nieuwenhuizen.)

1999-09-11  Marius Vollmer  <mvo@zagadka.ping.de>

        * readline.scm: Moved to ../guile-readline.

        * boot-9.scm (top-repl): Removed code for activating readline.

        * Makefile.am: Removed mention of readline.scm.

        * Makefile.in: Regenerated.
        
1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>

        Delete the test which compares the configuration date of libguile
        with the configuration date of ice-9.  This test yields too many
        false positives to be helpful.  For example, if you build Guile
        for several architectures but have them all share a "share"
        directory (which is supposed to work), then all but one
        architecture's Guile will complain that the configuration dates
        don't match.  Which is true, but indicates nothing wrong.
        * boot-9.scm: Delete code which compares ice-9-config-stamp with
        libguile-config-stamp.
        * version.scm.in: Delete.
        * Makefile.am (ice9_generated): Delete.
        (subpkgdata_DATA): Remove ice9_generated.
        (EXTRA_DIST): Remove version.scm.in.
        * Makefile.in: Regenerate.

1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

*       * debugger.scm: New file: Initial version of the Guile debugger
        written by Chris Hanson.  (The debugger isn't finished, but is
        included in Guile anyway since it is already quite useful.)
        Use readline conditionally.

*       * boot-9.scm (top-repl): Use (ice-9 debug) (ice-9 debugger) (ice-9
        session) (ice-9 threads) (ice-9 regex) from guile-user only if
        top-repl is called.  This makes startup time for scripts 30% of
        what it was before...  Removed redundant code for loading of
        readline.

        * Makefile.am (ice9_sources): Added debugger.scm.

1999-08-29  Keisuke Nishida  <kxn30@po.cwru.edu>

        * boot-9.scm (try-module-autoload): Use %search-load-path.
        
1999-08-24  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

        * boot-9.scm: Removed old style hooks.
        (inherit-print-state): Rwwritten to use port-with-print-state.

1999-08-20  James Blandy  <jimb@mule.m17n.org>

        Remove support for the #/ path list syntax entirely.
        * boot-9.scm (read-path-list-notation,
        read-path-list-notation-warning): Deleted.
        Don't register read-path-list-notation-warning as a reader for
        objects starting with '#/'.

1999-08-05  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

        GOOPS needs the observer protocol specified for the new module
        system.  Here's a simple version for the old module system:
        * boot-9.scm (module-observers, module-weak-observers,
        module-observer-id, set-module-observers!,
        set-module-observer-id!): New accessors.
        (module-type): Added slots `observers', `weak-observers' and
        `observer-id'.
        (module-observe, module-observe-weak, module-unobserve,
        module-modified): New procedures.
        (module-make-local-var!, module-add!, module-remove!,
        module-clear!, module-define!, module-use!): Call module-modified.

1999-07-29  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (error-catching-loop): Correct non-RnRS usage of internal
        defines.

1999-07-19  Jim Blandy  <jimb@savonarola.red-bean.com>

        * streams.scm: New module, contributed by Michael Livshin.
        * Makefile.am (ice9_sources): List it.
        * Makefile.in: Regenerated.

        * boot-9.scm (read-delimited!): Put the terminator in the correct
        position.

1999-06-29  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>

        * readline.scm: Bugfix: Avoid getting the continued-lines prompt
        at multiple calls to read.
        (promtp2): Variable for continued-lines prompt.
        (make-readline-port): Use prompt2.
        (set-readline-prompt!): New optional arg which sets
        continued-lines prompt.

        * boot-9.scm (top-repl): Set/clear readline prompts before/after
        reading expressions.

1999-06-18  Jim Blandy  <jimb@savonarola.red-bean.com>

        * ls.scm (ls, lls): Handle no arguments as meaning to look in
        `(current-module)'. (Patch from Thien-Thi Nguyen.)

1999-06-14  Jim Blandy  <jimb@savonarola.red-bean.com>

        * string-fun.scm (split-before-predicate, split-after-predicate,
        split-discarding-predicate): Make these public.  (Thanks to
        Thien-Thi Nguyen.)

        1999-06-13  Gary Houston  <ghouston@easynet.co.uk>

        * more changes to expect.scm, to avoid the one-character lookhead
        that was introduced to fix the $ problem:

        * expect.scm (expect): call the match proc an extra time at end
        of file and set the eof? argument appropriately.  call 
        expect-eof-proc only if the last call didn't match.
        * expect.scm (expect-strings): change port to eof? in match proc.
        * expect.scm (expect-regexec): take an eof indicator as an argument
        instead of a port.

1999-06-09  Jim Blandy  <jimb@savonarola.red-bean.com>

        * Makefile.am (ice9_sources): Add popen.scm to list.
        * Makefile.in: Regenerated.

        Fixes for expect from Gary Houston  <ghouston@easynet.co.uk>:

        * expect.scm (expect-regexec): define 'eof-next?'.  I don't
        know why it was missing.  also don't peek for end of lines
        unless expect-strings-exec-flags contains regexp/noteol.
        (expect-strings-exec-flags): initialise to regexp/noteol.

        Gary Houston's open-buffer port patches:

        1999-04-01  Gary Houston  <ghouston@easynet.co.uk>

        * popen.scm: applied fixes from Greg Harvey.  use a guardian
        and a gc-thunk so that cleanup is done if a pipe is garbage
        collected or closed with close-port.  use a weak hash-table instead of 
        an alist.
        
        1999-03-20  Gary Houston  <ghouston@easynet.co.uk>

        * expect.scm (expect): call the match proc with the port instead.
        (expect-strings): use peek-char to get the next char.  this has
        the advantage of getting the handling of $ "correct", but the
        disadvantage of needing to get (and maybe block for) an extra character
        from the port when it may not be needed.  hence:
        (expect-strings-exec-flags): new variable/parameter, supplies
        flags for regexp-exec.  if this includes regexp/noteol, then
        automatic regexp/noteol handling (requiring an extra peeked char) 
        is enabled.  default is regexp/noteol.
        (expect-strings-compile-flags): new variable/parameter, supplies
        flags for make-regexp.  default is regexp/newline.

        1999-03-15  Gary Houston  <ghouston@easynet.co.uk>

        * expect.scm (expect): call the match proc with an extra char,
        peeked from the stream.
        (expect-strings): build a match proc which takes the extra char.
        (expect-regexec): take an extra arg "eof-next?" and use it
        to decide whether the regexp/noteol flag should be added.

        1999-02-26  Gary Houston  <ghouston@easynet.co.uk>

        * boot-9.scm (top-repl): don't flush all ports at exit.
        (error-catching-loop): likewise.

        1998-12-23  Gary Houston  <ghouston@easynet.co.uk>

        * boot-9.scm (scm-style-repl): -read: don't call
        consume-trailing-whitespace if val is eof object.  Allows
        exiting repl with single control-D.

        1998-12-06  Gary Houston  <ghouston@easynet.co.uk>

        * boot-9.scm (error-catching-loop): don't force output within
        error catching loop after quit received.
        (top-repl): flush all ports when the repl terminates.

        * boot-9.scm (error-catching-loop): flush all ports before 
        primitive exit if non-interactive. 
        force-output on current-error-port if interactive.

        * boot-9.scm (reopen-file): deleted.
        * popen.scm (open-output-pipe, open-input-pipe): moved from
        boot-9.scm.
        * popen.scm: new file.

1999-06-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

       * boot-9.scm (iota):  replaced by a tail recursive version.
       (reverse-iota):  removed.

1999-06-03  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>

        * optargs.scm (lambda*): Bugfix: Replaced ARGLIST -->
        non-optional-args.  (Thanks to David Lutterkort.)

1999-05-09  Jim Blandy  <jimb@savonarola.red-bean.com>

        * string-case.scm: Removed; functions moved to libguile/strop.c
        (which could be dynamically linked in the future anyway).
        * Makefile.am (ice9_sources): Don't list string-case.scm.
        * Makefile.in: Regenerated.
        * format.scm: Don't bother importing (ice-9 string-case).

1999-05-02  Jim Blandy  <jimb@savonarola.red-bean.com>

        * boot-9.scm (provided?): New function.

        * Makefile.am: Add string-case.scm and format.scm to ice9_sources.
        * Makefile.in: Regenerated.
        
        * string-case.scm: New file, brought in from SLIB, and adapted to
        Guile's module system.

        * format.scm: New file, brought in from SLIB, with the following
        changes:
        (format:format): If the first argument is the format string, stick
        a #f on the front of it, so it is now a valid CL format argument
        list.  This is easier than changing everyplace else (like the
        error formatter) that expects it to be in CL form.  The other
        clause which explicitly tests for this case is now dead code.
        (format:format-work): Allow `@' and `:' in either order, as per
        modern CL behavior.
        (format:num->cardinal): Don't assume that an elseless if returns
        '() when the condition is false.
 
1999-04-17  Jim Blandy  <jimb@savonarola.red-bean.com>

        * Makefile.in: Regenerated.

1999-04-08  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm: Provide 'values.

1999-03-21  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (process-define-module, use-syntax): Bugfix:
        :use-syntax should add syntax to using module, not current module.
        (internal-use-syntax): Removed.

1999-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * session.scm (apropos-internal): Modified to comply with new
        argument order for hash-fold.

1999-03-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (try-load-module): New procedure.  Broken out from
        resolve-module.
        (resolve-module): Bugfix: Make it possible for a module at a
        deeper level (x y z) to depend on a module on a higher (x y).

        This also has the desired side-effect that multiple attempts to
        load a module (e.g. with `use-modules') work until source is
        actually found for the module (e.g. because the correct catalog
        has been added to the load path).
        
        Use try-load-module.

1999-03-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * session.scm (system-module): New procedure.  Used to switch a
        module between system and user state.

1999-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * session.scm (apropos-internal): Rewritten using hash-fold.

        * emacs.scm, session.scm, slib.scm): Added :no-backtrace in module
        definition.

1999-03-14  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (make-record-type): Use `set-struct-vtable-name!' to
        associate a name to the record type descriptor so that the object
        system can create a wrapper class for it.

1999-03-12  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        Improvement of backtraces: Introduces a new stack narrowing
        specifier, #t, for the inner cut.  If the inner cut is specified
        by #t, `make-stack' will throw away inner stack frames (most
        recent calls on call chain) up to but excluding the first user
        stack frame encountered.

        This specifier is now used in `save-stack' so that the call
        `(save-stack)' will get the new behaviour. [It is recommended that
        any error reporting functions written by the user have this call
        on the outermost expression level (i.e. as a member of the lambda
        list).]

        Modules are partitioned into "user" and "system" modules. [I know
        that some names used here are silly, but I don't have more time to
        spend on a better solution, especially considering that the module
        system will be replaced.  But if people have better ideas, then
        please tell me!]

        System modules are created by adding :no-backtrace among the
        define-module switches:

        (define-module (foo)
          :no-backtrace)

        Modules which doesn't have the :no-backtrace specifier are user
        modules.
        
        A stack frame is classified as a user frame if it has source code
        associated with it and if this source code can be proven to come
        from a user module.  If it can be proven to come from a system
        module it is a system frame.

        Frames which can't be classified, e.g. application frames, are cut
        away if they occur between system frames, but are left on the
        stack if they occur between the last system frame and the first
        user frame encountered.  (Note that the first user frame
        encountered is the last user code being evaluated!)

        In some cases the system part of the call chain is introduced by
        frames which should but can't be proven to be system frames.  The
        following workaround has been implemented: The cutting proceeds
        over application frames where the operator is marked by the
        `system-procedure' property.  (This has been used to cut away
        generic function dispatch code in the object system.)

        * boot-9.scm (set-system-module!): New procedure: Set system/user
        status of a module.;
        Mark `the-root-module' and `the-scm-module' as system modules.
        (process-define-module): Add new keyword :no-backtrace.

        * boot-9.scm (environment-module): Bugfixed.
        (set-module-eval-closure!): Add a pointer back from the eval
        closure to the module.

        * emacs.scm (emacs-load): Reset port filename after transfer.

1999-03-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * slib.scm (make-random-state): Added for compatibility.

1999-02-16  Maciej Stachowiak  <mstachow@alum.mit.edu>

        * optargs.scm (lambda*): Handle empty argument lists properly.

1999-02-15  Jim Blandy  <jimb@savonarola.red-bean.com>

        Fix from Russ McManus:
        * getopt-long.scm (parse-option-spec): Store 'optional as the
        value-required? field for options that take optional values.
        (process-short-option): Grab a value for the option when it takes
        either an optional or required value.

1999-02-12  Jim Blandy  <jimb@savonarola.red-bean.com>

        * getopt-long.scm: Remove debugging calls to `pk'.

        * getopt-long.scm: Return list of ordinary arguments as the value
        of the '() key, not `rest'.

        A new argument-processing package from Russ McManus.
        * getopt-long.scm: New file.
        * Makefile.am (ice9_sources): Added getopt-long.scm.
        * Makefile.in: Regenerated.

1999-02-09  Maciej Stachowiak  <mstachow@alum.mit.edu>

        * optargs.scm: New file. 
        * Makefile.am (ice9_sources): Add optargs.scm here. Makefile.in
        not regenerated because I don't have the right version of Automake.

1999-02-06  Jim Blandy  <jimb@zwingli.cygnus.com>

        * and-let*.scm: New file, from Michael Livshin.
        * Makefile.am (ice9_sources): Add and-let* here.
        * Makefile.in: Regenerated.

1999-01-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * slib.scm (install-require-module): Fixed the kludge which loads
        the slib catalog: Doesn't anylonger assume that the feature tested
        for isn't loaded.

1998-12-14  Jim Blandy  <jimb@zwingli.cygnus.com>

        * Makefile.in: Regenerated.

1998-12-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (process-define-module): Reverted the change of
        1998-11-23 which caused loading of object code if :use-module was
        applied to the module itself.

1998-12-11  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * Makefile.am: Removed setf.scm.

        * setf.scm: Removed.  1. It was buggy.  2. It was unschemey.
        (These shortcomings were my fault.)

1998-12-10  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (environment-module): New procedure.

1998-12-07  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * Makefile.am: Added setf.scm.

1998-12-05  Christian Lynbech  <chl@tbit.dk>

        * setf.scm: New file.  Adds the new forms `setf!' and `setter'
        which implements generalized references a la Common LISP.

1998-12-02  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (process-define-module): Added new specifier
        :autoload MODULENAME BINDINGS to the define-module form.
        The autoload specifier tells the module system to load the module
        MODULENAME at the first occasion that any variable with its name
        among BINDINGS is referenced.
        (make-autoload-interface): New procedure:  Constructs a stand-in
        for the public interface for the module to be autoloaded.

1998-12-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (*suppress-old-style-hook-warning*): Set this to #t
        if you don't want the old style hook warnings.

1998-12-01  Christian Lynbech  <chl@tbit.dk>

        * boot-9.scm (try-using-libtool-name): Fix check on dlname to make
        sure that it isn't empty, as it is when we are only buidling
        static libraries.

1998-11-27  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * session.scm (arity): New procedure.

1998-11-26  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm: Use run-hook instead of run-hooks everywhere.

1998-11-26  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (run-hooks, add-hook!, remove-hook!): Added temporary
        code for backward compatibility until people have had time to
        adapt to the new hooks.

1998-11-23  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (beautify-user-module!): Beautify also if public
        interface is set to the module itself.  In this way we can use
        beautify-user-module! to beautify a module prepared for object
        code.
        (process-define-module): Special case: Try to load object code as
        well if a module does :use-module on itself.

        * boot-9.scm: Bugfix: Since boot-9.scm is now loaded from
        invoke_main_func, we can no longer be sure that all modules have
        been registered when boot-9.scm is loaded.
        (register-modules): New function: Register and tag modules
        registered by scm_register_module_xxx since last call to this
        function.  Modules are tagged with the dynamic object passed as
        argument.  (Already linked modules should be tagged with #f.)
        (init-dynamic-module, link-dynamic-module): Call register-modules
        first to register linked modules.

        * boot-9.scm (init-dynamic-module): Remove module from
        registered-modules as soon as possible in case we are recursively
        invoked; Set public interface before doing the dynamic-call.
        
        * boot-9.scm (map-in-order): Removed (replaced by scm_serial_map).
        (abort-hook, before-error-hook, after-error-hook,
        before-backtrace-hook, after-backtrace-hook, before-read-hook,
        after-read-hook, exit-hook): Make hooks with `make-hook'.

        * boot-9.scm: Make hooks first class citizens and make them easier
        to use from C:
        (make-hook, add-hook!, remove-hook!, run-hooks): Moved to
        libguile/feature.c.

        * boot-9.scm: Added warnings about bindings used in
        libguile/modules.c: the-module, set-current-module,
        make-modules-in, beautify-user-module!, module-eval-closure.

1998-11-21  Mikael Djurfeldt  <mdj@kenneth>

        * boot-9.scm (the-environment): New special form: Returns an
        object representing the current local evaluation environment.
        This object can be used in `local-eval' and `defined?'.

1998-11-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (collect): New syntax.  Similar to begin but returns
        a list of the results of all forms in the sequence instead of the
        result of the last form.

1998-11-10  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (values, call-with-values): Moved here from
        syncase.scm.

        * syncase.scm (values, call-with-values): Moved to boot-9.scm.

        * boot-9.scm (readline-options, readline-enable, readline.disable,
        readline-set!: New options interface.

        * readline.scm (readline-port): Use readline-options-interface.

1998-11-05  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm: Set the repl start module in `top-repl' instead of
        at the end of boot-9.scm.

1998-11-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * emacs.scm (format): Bugfix: Handle multiple arguments
        correctly.  (Thanks to Thien-Thi Nguyen.)

1998-11-01  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (exit-hook): New hook: Is run at the very end of an
        interactive session.
        (top-repl): Run exit-hook on exit.

        * readline.scm (readline-port): Maybe read history; Maybe write
        history at exit (add to exit-hook).

Fri Oct 30 15:15:37 1998  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * readline.scm (make-readline-port): Bugfixed last change...

1998-10-28  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * readline.scm (make-readline-port): Don't set prompt to "... " if
        read line was empty.

1998-10-19  Jim Blandy  <jimb@zwingli.cygnus.com>

        * boot-9.scm, debug.scm, expect.scm, hcons.scm, lineio.scm,
        r4rs.scm, slib.scm, threads.scm: Update copyright years.

        * getopt-gnu-style.scm, slib.scm: Add copyright notice.

        Talked to Stallman.  Actually, the syntax-case copyright is no
        problem.  Duh.
        * Makefile.am (ice9_sources): Revert last change.
        * syncase.scm, psyntax.pp, psyntax.ss: Added again.
        * Makefile.in: Regeneretade.

        * boot-9.scm: Don't assume that this file is loaded just before
        entering a read-eval-print loop.  Turn code to load (ice-9 emacs)
        into...
        (load-emacs-interface): New function.
        (top-repl): Call it, if use-emacs-interface is defined and true.
        At this point, we *do* know we're about to enter a REPL.

        We can't include Kent Dybvig's syntax-case macro expander in the
        core Guile distribution, because we don't have copyright
        assignments for this code.  We can certainly distribute them as a
        separate package, but Guile should be FSF code.
        * syncase.scm, psyntax.pp, psyntax.ss: Removed.
        * Makefile.am (ice9_sources): Removed syncase.scm, psyntax.pp, and
        psyntax.ss.
        * Makefile.in: Regenerated.

        * Makefile.am (ice9_sources): Add getopt-gnu-style.scm.
        * Makefile.in: Regenerated.

1998-10-18  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm: Added extended read syntax for byte vectors #y(...)
        and short vectors #h(...).

1998-10-14  Jim Blandy  <jimb@zwingli.cygnus.com>

        * calling.scm (excursion-function-syntax): Use a sequence of
        set!'s, not a single multi-variable set!; we removed support for
        that syntax a long time ago.  (Thanks to Shuji Narazaki.)

1998-10-12  Jim Blandy  <jimb@zwingli.cygnus.com>

        * r4rs.scm (OPEN_READ, OPEN_WRITE, OPEN_BOTH): Don't bother
        testing software-type here.  That's the least of our Windows
        porting issues, and it's done wrong anyway.

1998-10-09  Jim Blandy  <jimb@zwingli.cygnus.com>

        * boot-9.scm (read-path-list-notation-warning): New function:
        print a warning the first time we see `#/' notation.

        * q.scm (sync-q!, q?, q-remove!, q-push!, enq!): Lots of bugs, and
        (eq?  #f '()) assumptions.  Make functions that aren't documented
        to return anything else return the queue itself.  (Bug report from
        Michael Livshin --- thanks!)

1998-08-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * debug.scm (trace-entry, trace-exit): Removed re-enabling of
        trace flag.

        * boot-9.scm (make-options): Bugfix: Changed pair? --> list? in
        order to allow the empty list as arg.
        (error-catching-loop): Use `with-traps' to create a dynamic
        context with traps enabled.

1998-08-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm: Removed (ice-9 regex) from use-list of (guile)
        module.
        (try-using-libtool-name): Removed dependency on (ice-9 regex).

1998-08-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm: Make the root module use (ice-9 regex) if
        available.  The dynamic linking facilities in boot-9.scm are
        currently dependent upon regular expressions.  My change of
        1998-07-14 removed (ice-9 regex) from the use-list of the root
        module and thereby destroyed dynamic linking.

1998-07-29  Jim Blandy  <jimb@zwingli.cygnus.com>

        * Makefile.in: Regenerated using the last public version of
        automake, not the hacked Cygnus version.

1998-07-28  Jim Blandy  <jimb@zwingli.cygnus.com>

        * Makefile.in: Regenerated, after removing Totoro kludge.

1998-07-28  Jim Blandy  <jimb@totoro.red-bean.com>

        * getopt-gnu-style.scm: New file.  (Thanks to Russ McManus.)

1998-07-26  Jim Blandy  <jimb@zwingli.cygnus.com>

        * Makefile.in Rebuilt, for config changes in parent dir.

1998-07-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * readline.scm (make-readline-port): Set prompt string to "... "
        after first read line.  (Thanks to Richard Polton.)

1998-07-19  Jim Blandy  <jimb@zwingli.cygnus.com>

        * lineio.scm (make-line-buffering-input-port): Don't use
        ungetc-char-ready?, since we don't provide that function any
        more.  The unread-string function doesn't interact properly with
        any of the standard I/O functions anyway.  (Thanks to Andrew
        Archibald.)

        * hcons.scm (hashq-cons-assoc): Don't assume the empty list is
        false.  Return false when we cannot find a matching entry in the
        list.  (Thanks to Andrew Archibald.)

1998-07-16  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (export, export-syntax): New special forms: Export
        bindings from a module.  `(export name1 name2 ...)' can be used at
        the top of a module (after `define-module') to specify which names
        should be exported.  It can be used as an alternative to
        `define-public'.  `export-syntax' works equivalently to `export'
        but is intended for export of syntactic keywords.
        (Thanks to Thien-Thi Nguyen.)

1998-07-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm: Renamed module `(guile-repl)' --> `(guile-user)'.

1998-07-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm: Let the user start in module `(guile-repl)' instead
        of module `(guile)'.  Also make sure that `(guile-repl)' uses
        suitable modules.  This change improves Guile stability
        substantially since bindings will only be copied from the root
        module: If the user redefines builtins in `(guile-repl)' it won't
        affect the internal operation of Guile itself.

1998-06-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * boot-9.scm (load-module): When loading files from within files
        themselves being loaded: Use the directory path of the file being
        loaded as root for relative filenames.  (After suggestion by
        Steven G. Johnson.)

1998-06-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * emacs.scm (emacs-load): New feature: Eval in specified module.

1998-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * readline.scm: Typo in regex module name.

1998-06-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

        * readline.scm (apropos-completion-function): regexp-quote text to
        be completed.

1998-06-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * debug.scm, emacs.scm: Bugfix: Treat `the-last-stack' as a fluid.

1998-06-09  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm: Check that (current-input-port) is a tty before
        enabling readline.  (Thanks to Michael N. Livshin.)

1998-06-07  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (use-syntax): Turned into a macro inorder to be
        similar in use to `use-modules'.
        Example: (use-syntax (ice-9 syncase)) will 1. load the module
        (ice-9 syncase), and, 2. install the procedure `syncase' as eval
        transformer.
        (internal-use-syntax): New procedure.
        (process-define-module): Use `internal-use-syntax'.

1998-05-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * Makefile.am (ice9_sources): Add emacs.scm.

1998-05-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * readline.scm: Use the new readline facilities: Add the
        possibility to control input and output ports; Add apropos
        completion.

        * boot-9.scm: Antirevert Jim's readline code which he reverted
        19971027 and adapt it to the current readline interface.
        
        * boot-9.scm (top-repl): Only enable readline if not using the
        Emacs interface; Only use repl prompt when using the readline port
        from repl-read.  (We don't want to see it when calling `read'.)

        * boot-9.scm (remove-hook!): Parenthesis bug.

1998-05-11  Mikael Djurfeldt  <mdj@kenneth>

        * boot-9.scm: Load readline module if readline is present.

        * readline.scm (apropos-completion-function): New procedure:
        Symbolic completion.  (Thanks to Andrew Archibald!)

1998-04-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (process-define-module): Added keyword use-syntax.

1998-04-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * nonblocking.scm: Removed.  libguile is now inherently
        nonblocking through the use of scm_internal_select.
        
        * emacs.scm: Removed use of nonblocking.scm.

        * gwish.scm, gtcl.scm: Removed.  tcltk.scm has made these
        obsolete.
        
1998-04-15  Mikael Djurfeldt  <mdj@nada.kth.se>

        * runq.scm (runq-control): Corrected spelling of enqueue!.
        (Thanks to Karl M. Hegbloom.)

1998-03-30  Mikael Djurfeldt  <mdj@nada.kth.se>

        * boot-9.scm: Added new run-time option interface eval-options.

1998-03-28  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (remove-hook!): New macro.  (Thanks to Maciej
        Stachowiak.)

1998-01-30  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * threads.scm: Added simple error and signal handler.
        (make-thread, begin-handler): Use this handler.  The most
        important effect of this is that signals get unmasked.
        Previously, when a signal was thrown signals remained masked
        (signals get masked when a signal is taken) which influenced other
        threads.

1998-01-01  Tim Pierce  <twp@skepsis.com>

        A better fix to the SLIB identity problem -- thanks to Marius Vollmer.
        * slib.scm (identity): Unmake public.
        (slib:eval): Evaluate inside `slib-module'.

1997-12-24  Tim Pierce  <twp@skepsis.com>

        * boot-9.scm: Doc fix.

        * slib.scm (identity): Made public.
        (home-vicinity): New function (from SLIB/Template.scm).

1997-12-13  Tim Pierce  <twp@skepsis.com>

        * boot-9.scm (read-line): Rewritten to call %read-line for
        improved speed.  Minor user-visible changes: the new functions are
        hardwired to treat the LFD character as signifying end-of-line, so
        changing `scm-line-incrementors' will no longer affect the
        behavior of read-line.  On platforms which do not represent
        end-of-line with a LFD character, read-line should behave more
        like native line-processing facilities, but there is still a ways
        to go here.

Sat Nov 29 01:24:46 1997  Mikael Djurfeldt  <mdj@kenneth>

        * boot-9.scm (error-catching-loop, save-stack): `the-last-stack'
        is now a fluid.

1997-11-28  Tim Pierce  <twp@skepsis.com>

        * boot-9.scm (find-and-link-dynamic-module): If a module directory
        contains a .la file (a libtool support file), attempt to extract
        the shared library name from that file.  If the .la file does not
        exist, try to link against a .so file.  Libtool-generated compiled
        modules should load more cleanly in Guile now.
        (try-using-libtool-name, try-using-sharlib-name): New functions.

Sun Nov  9 06:10:59 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (set-batch-mode?!, batch-mode?): initialize more
        usefully so they will work from a script.

1997-10-31  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (inherit-print-state): Moved definition to the
        neighborhood of the record code.

Mon Oct 27 02:05:49 1997  Jim Blandy  <jimb@totoro.red-bean.com>

        * boot-9.scm: Revert changes to this file from Oct 23.  It turns
        out to interact badly with the Emacs support and the Tcl/Tk
        support.  It's not a high enough priority at the moment to be
        worth fixing.  I'm leaving the other readline support in, though.

Sat Oct 25 14:23:22 1997  Jim Blandy  <jimb@totoro.red-bean.com>

        * Makefile.am: Include readline.scm in the list of files to be
        installed, so Guile can find it for interactive use.
        * Makefile.in: Regenerated.

Thu Oct 23 01:00:33 1997  Jim Blandy  <jimb@totoro.red-bean.com>

        Add support for readline function.
        * readline.scm: New module.
        * boot-9.scm (repl-reader): New function.
        (scm-style-repl): Call repl-reader, instead of doing the reading
        ourselves.  Remove repl-report-reset; it was never used for
        anything.
        (top-repl): If we've got the readline primitives, then redefine
        repl-reader to use them.
        If we've got the readline primitives, import the readline module.

        * ls.scm (ls, lls): Don't assume (eq? #f '()).

Wed Oct 22 18:26:57 1997  Jim Blandy  <jimb@totoro.red-bean.com>

        * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
        string-fun.scm: Added copyright notices; reformatted.

Thu Oct  9 05:44:00 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * expect.scm: (expect-regexec): new procedure, use it in
        expect-strings to fix the => syntax under the new regex system.
        (top): include regex module in define-module statement.

Wed Oct  8 03:16:01 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * (error-catching-loop): new local variable "interactive".  if
        #f, abort terminates the process.
        (set-batch-mode?!, batch-mode?): new closures, defined in 
        error-catching-loop.  the names are from scsh.

1997-10-06  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (inherit-print-state): If NEW-PORT contains a
        print-state, throw it away.

Fri Oct  3 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>

        * boot-9.scm (struct-layout): Use `vtable-index-layout' instead of
        `0'.

Thu Oct  2 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>

        * boot-9.scm (struct-printer, make-struct-printer,
        set-struct-printer-in-vtable!, *struct-printer*): Removed.
        (record-type-vtable, make-record-type): Don't use make-struct-printer.
        (record-type-vtable): User fields "prpr" (printer is no longer a
        user field).
        (record-type-name, record-type-fields): Decreased slot index by
        one; Use `vtable-offset-user'.

Thu Oct  2 12:00:00  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (inherit-print-state): New experimental function.

Tue Sep 30 13:12:48 1997  Jim Blandy  <jimb@totoro.red-bean.com>

        Suggestion and script from Maciej Stachowiak:
        * boot-9.scm: Split off modules into separate, autoloadable files.
        This reduces startup time from 10.5s to 5.5s (user cpu).
        * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
        string-fun.scm: New files, containing stuff that used to be in
        boot-9.scm.
        * Makefile.am (ice9_sources): List new files here, for
        distribution and installation.
        * Makefile.in: Regenerated.

Mon Sep 29 23:53:55 1997  Jim Blandy  <jimb@totoro.red-bean.com>

        * Makefile.in: Regenerated with automake 1.2c.

Mon Sep 29 03:21:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * slib.scm (slib:load): slib:load first tries to load the file
        named NAME, then NAME.scm.  On error, report the error occuring at
        the first attempt (NAME) rather than the second (NAME.scm).

        * boot-9.scm: Bugfix: Hard-solder the print-option procedure into
        the make-options macro so that we needn't refer to a global
        symbol.

Sun Sep 28 21:40:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * debug.scm: Moved options interface procedures to boot-9.scm.

        * boot-9.scm: Define options interface procedures here instead.

Sat Sep 27 20:19:20 1997  Jim Blandy  <jimb@totoro.red-bean.com>

        * boot-9.scm (separate-fields-discarding-char,
        separate-fields-after-char, separate-fields-before-char): Call
        continuation function, RET, as advertised: with each separated
        field a separate argument.

        * Makefile.in: Regenerated with automake 1.2a.

Sat Sep 20 14:23:53 1997  Mikael Djurfeldt  <mdj@kenneth>

        * slib.scm (slib:load): Export.

        * boot-9.scm (in-vicinity): Bugfix: Don't add "/" to an empty
        vicinity;
        Provide defmacro.

Thu Sep 18 01:24:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * r4rs.scm (apply): Set name property to 'apply.

Tue Sep 16 22:09:50 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (keyword->symbol, display-usage-report): Changed
        length --> string-length.  (Thanks to Aleksandar Bakic.)
        (separate-fields-discarding-char, separate-fields-after-char,
        separate-fields-before-char): Bugfix from Maciej Stachowiak
        <mstachow@mit.edu>.  Thanks!
        (try-module-linked): Try to find module among those already
        registered.
        (try-module-dynamic-link): Removed the first test which
        corresponds to a call to `try-module-linked'.
        (resolve-module): Resolve modules in this order: 1. Already
        registered modules (for example those which have been statically
        linked), 2. Try to autoload an .scm-file, 3. Try to dynamically
        link a .so-file.

Mon Sep 15 23:39:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (iota): Renamed list-reverse! --> reverse!

        * boot-9.scm (primitive-macro?): New procedure.

        * slib.scm: Added hack which transfers syntactic information from
        the builtin variable `define' to the slib version if module (ice-9
        syncase) has been loaded.  This is necessary to get correct
        expansion inside the slib module.

        * psyntax.ss (build-let, build-named-let): New output
        constructors.
        (build-lexical-var): Seed gensym with symbolic name.
        (self-evaluating?): Add keywords among self-evaluating types.
        (let): New core form.
        (if): Removed from core language.
        (or, and, let, cond): Removed syntactic definitions.
        (sc-expand3): New procedure: Expander which takes optional mode
        and eval-syntactic-expanders-when arguments.

        * syncase.scm (psyncomp): New procedure: Recompiles psyntax.pp.
        Should be used inside the (ice-9 syncase) module with (use-syntax
        syncase) and with the current directory containing the psyntax.ss
        source.
        Added hack to transfer syntactic information from the builtin
        variable `define' to the slib version if module (ice-9 slib) has
        been loaded.
        
Fri Sep  5 05:47:36 1997  Mikael Djurfeldt  <mdj@faun.nada.kth.se>

        * syncase.scm (sc-interface, sc-expand): Removed hook setup.
        (syncase): Publish syntax transformer to be used with
        `use-syntax'.
        (sc-macro): Use this as the value when publishing macros.

        (make-module): Modified initialization.
        (module-transformer, set-module-transformer!): Selector and
        mutator for module-associated transformer.

        (use-syntax): New function: Install a transformer in current
        module.
        (sc-interface, sc-expand): Removed! :)

        * emacs.scm (emacs-load): Added new parameter `module'.

        * syncase.scm (putprop, getprop): Modified to use the object
        properties of the variable object corresponding to the symbol;
        This way we can ride on the mechanisms of the module system.
        Changed `builtin-variable' calls to `define-public' calls.
        Setup the hooks sc-expand and sc-interface.

        * boot-9.scm (sc-interface, sc-expand): New builtin variables.
        (set-current-module): Switch to and from sc-expand as
        scm:eval-transformer when going into and out of modules using
        syncase macros.
        (module-use!): Set scm:eval-transformer to sc-expand when adding
        the syncase interface.

Thu Sep  4 14:57:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * syncase.scm (putprop): Temporary fix which publishes new syntax
        globally (the old behaviour was complex and connected to the inner
        workings of the current module system).

Wed Sep  3 21:29:13 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * psyntax.ss: Updated.
        psyntax.pp: Bugfix: Previous version had some leading "t":s cut
        off!

Tue Sep  2 00:26:42 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (gensym): Removed (replaced by primitive).
        (obarray-gensym): Rewritten to use `gensym'.
        (gentemp): Rewritten to use `gensym'.

Mon Sep  1 20:08:32 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * gtcl.scm (make-tcl-binder): Rewritten to choose bindings
        according to the following priorities:
        1. tcl bindings which are present in override-scheme-list
        2. bindings from the-scm-module
        3. tcl bindings
        This way the gtcl module can occur first in the use-list without
        disabling the scheme interpreter.
        (new-interpreter): New function.

        * gwish.scm: Moved initialization code for the-interpreter to
        gtcl.scm; Moved name space cleaning code to gtcl.scm and rewrote
        it; Call `new-interpreter'; Don't :use-module (guile).

Thu Aug 28 23:48:53 1997  Jim Blandy  <jimb@totoro.red-bean.com>

        * Makefile.in: Regenerated.

Wed Aug 27 11:35:09 1997  Jim Blandy  <jimb@totoro.red-bean.com>

        * Makefile.in: Regenerated, so it uses "tar", not "gtar".

Mon Aug 25 22:00:44 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * emacs.scm (object->string, format, error-args->string): New
        procedures.
        (emacs-frame-eval): Reworked.

Mon Aug 25 16:15:55 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * session.scm (apropos-internal): Musn't initialize symbol
        accumulator with a constant pair.  That led to mutation of the
        source!

Sun Aug 24 01:03:10 1997  Mikael Djurfeldt  <mdj@kenneth>

        * session.scm (vector-for-each): Removed.
        (apropos): vector-for-each --> array-for-each.
        (apropos-internal): New function.  Return list of accessible
        symbols matching regexp.

        * debug.scm (frame-number->index): New function.  Convert frame
        number (as displayed in the backtrace) to frame index (to be used
        in stack-ref).

        * emacs.scm (emacs-load): New arguments: interactivep: when
        non-false, send back results to Emacs; colnum: Column number;
        Use modules (ice-9 debug) and (ice-9 session);
        (no-stack, no-source): New simple-actions;
        (result-to-emacs): New procedure. Sends data to Emacs via the

Tue Aug 19 02:39:41 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * syncase.scm: Don't tamper with debug mode setting when enabling
        macros.  Instead cut the stack with start-stack.
        Load psyntax.pp with recording of positions turned off.

        * psyntax.pp, psyntax.ss (quasiquote): Changed fx= --> =.

        * syncase.scm: New file: Guile-adaption for syntax-case macros.
        * psyntax.pp, psyntax.ss: Syntax-case macros, portable version 2 by
        R. Kent Dybvig, Oscar Waddell, Bob Hieb and Carl Bruggeman

Mon Aug 18 21:58:25 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * session.scm: New file: Session support.
        (apropos): New procedure: List bindings given regexp.

Sat Aug 16 18:44:24 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm: define tms accessors: clock, utime, stime, cutime,
        cstime.

Thu Aug 14 19:55:37 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * emacs.scm (emacs-load): Something has changed in the reader so
        that we now should set the port line count to the specified value
        (linum) instead of (- linum 1).

        * slib.scm (slib:load): Use load-from-path instead of
        primitive-load-path so that backtraces get narrowed properly at
        the top.

        * boot-9.scm (top-repl): Save stack already in signal handler in
        order to narrow it correctly.
        (save-stack): Adjust narrowing tag for the top of load-stacks.

Tue Jul 29 01:18:08 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (move->fdes, dup->port): use dup->fdes, not primitive-dup.
        (dup->fdes): deleted, now done in C.

Sat Jul 26 08:00:42 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (setenv): new procedure, scsh compatible.

Sat Jul 26 21:30:10 1997  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (with-fluids): New macro to go with the
        builtin `with-fluids*'.

Thu Jul 24 04:28:11 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * slib.scm (install-require-module): In newer versions of slib
        *catalog* is #f until the first access.  Therefore we call
        require:provided? for a random feature if *catalog* is #f.

Wed Jul 23 20:13:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm: If using emacs interface, enable backtraces
        automatically.

        dup, fdes->inport, fdes->outport, port->fdes): new procedures.
        (duplicate-port): was a C primitive, now it's here.
        (move->fdes): allow the first argument to be a file descriptor.
        Return the modified port or file descriptor (was unspecified.)

Fri Jul 11 00:13:43 1997  Jim Blandy  <jimb@floss.red-bean.com>

        Changes to compile under gnu-win32, from Marcus Daniels:
        * boot-9.scm (load-user-init): If HOME is unset, provide
        a default of /.

        * boot-9.scm (define-public): Changed to accomodate Hobbit.

Tue Jun 24 00:31:47 1997  Jim Blandy  <jimb@floss.red-bean.com>

        * boot-9.scm, debug.scm, hcons.scm, lineio.scm, mapping.scm,
        poe.scm, slib.scm, tags.scm, threads.scm: Use normal list
        notation, instead of #/ notation.

        * expect.scm (expect-strings): Pass regexp/newline flag to
        make-regexp.

        Fix inconsistencies in parsing of #/ style lists.
        * boot-9.scm (read-path-list-notation): New function.
        (parse-path-symbol): Deleted.  Replaced by above.
        Plug in read-path-list-notation as the parser for #/ lists,
        instead of the anonymous lambda form calling parse-path-symbol.
        (Thanks to Maurizio Vitale.)
        
        * boot-9.scm (make-list): Remove the definition of this function
        from the (ice-9 common-list) module; make the `init' argument
        optional in the scm module's definition, to match the deleted
        definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)

Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>

        Try to detect when people are using one version of libguile and a
        different version of ice-9.  People have been skewing things and
        sending in bug reports.
        * version.scm.in: New file, which the configure script munges to
        produce version.scm, which contains the ice-9 config stamp.
        * boot-9.scm: Compare the libguile and ice-9 config stamps;
        display a warning if the two are different.
        * Makefile.am: Install version.scm, but don't distribute it.
        Distribute version.scm.in, but don't install it.
        * Makefile.in: Regenerated.

Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>

        check.  Correctly check for struct printer tag.

        * expect.scm: Turn this into a module, (ice-9 expect).
        (expect-port, expect-timeout, expect-timeout-proc,
        expect-eof-proc, expect-char-proc, expect, expect-strings,
        expect-select): Make these public definitions.
        (expect-strings): Use make-regexp and regexp-exec, instead of
        regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
        that's okay.

        * boot-9.scm (with-regexp-parts): Comment this out.  It has no
        users in the core, and relies on mildly hairy details of the old
        regexp interface.

        * test.scm: Re-enable tests asserting that '() is true, and not a
        boolean.  This stuff has been true for a while.

        * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
        function names.

        * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
        fixes.

Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>

        ../configure.in.

Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (struct-printer): Bugfix: Check the layout of the
        vtable and not the one of the struct.

Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
        make-struct-printer, set-struct-printer-in-vtable!): New bindings
        to support printing of structures.
        (record-type-vtable, make-record-type): Add slot to hold printing
        function and initialize it with something appropriate.  Removed
        commented out printing code.
        (record-type-name, record-type-fields): Adjusted slot offsets.
        (%print-module): Reduce argument list to "mod" and "port".
        
Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>

        * slib.scm (identity): New function, used by SLIB.

Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm: signal-handler, alarm-thunk: removed.
        don't define ticks-interrupt etc.

        during call to scm-style-repl.
        
Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * slib.scm (slib:load): Use primitive-load-path instead of
        basic-load.  This is probably wrong, but hopefully the entire
        source access system will be revised soon anyway, and this will
        make require behave more like Emacs Lisp's require.  If this
        breaks something, please let me know.  Maybe this is real dumb.

Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
        * boot-9.scm: If the `regex' feature is present, use the module
        (ice-9 regex).

        * regex.scm: New file.

        gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
        oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
        threads.scm: New address for FSF.

Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * debug.scm: Update copyright years; this file has been worked on
        in 1997.

Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * expect.scm: use gettimeofday instead of get-internal-real-time
        and use a floating point timeout when calling select.  Untested,
        since the regex library is currently AWOL.

Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm (eval-string): Function deleted; it was already
        implemented in C, so there's no point in making a divergable copy
        here.

Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * Makefile.in: Regenerated, using automake-1.1p.

Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (error-catching-loop): don't read a line from
        current input when quit is encountered, the previous change
        fixes this too.

Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm (scm-style-repl): After reading an expression,
        consume any trailing newline (perhaps preceded by whitespace), to
        avoid screwing up GDB.  More detail in comments.

Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
        the Scheme code like code yet.
        * Makefile.in: Resrac,husrched.

Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (link-dynamic-module): Do not catch errors from
        dynamic-link and dynamic-call.  When the shared library exists it
        is now assumed to be suitable for a dynamic C module.
        
Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (process-use-modules): New function to support the
        use-modules macro
        (use-modules): throw an error iff one of the requested modules
        can't be found.
        
Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm: don't define timer-thunk or gc-thunk.

Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * aclocal.m4: Removed; unnecessary, given changes of Apr 24.

        * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
        we're not using AM_INIT_GUILE_MODULE any more.
        * Makefile.in: Regeneratitetedrerd.

Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>

        Get 'make dist' to work again.
        * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
        * Makefile.in: Regenerated, like two tons of fleas.

        Changes for reduced Guile distribution: one configure script,
        no plugins.
        * configure.in, configure: Removed.
        * Makefile.in: Regenerated.

Sat Apr 19 08:03:50 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm (eval-string, command-line, load-user-init): New
        functions.

Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (log10): defined.

Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * expect.scm (expect-select): correct the millisecond timeout
        arithmetic (from Marko.Kohtala@ntc.nokia.com).
        
Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (open-input-pipe, open-output-pipe): defined here
        instead of in libguile.
        (tm:sec etc.) new accessors for broken-down time.
        (set-tm:sec etc.) new setters for broken-down time.

Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (netent:addrtype, servent:port): added missing
        procedures.
        (netent:net, servent:proto): repaired.
        (utsname:sysname etc.): new accessors for uname.

Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
        sockaddr:port): new functions.

Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm: define accessor procedures for the objects returned
        by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
        passwd:name, where the first component is the name of the C structure
        and the second is the unprefixed C member name.)

Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
        setservent): no longer take an argument, it was bogus.

Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (scm-error): deleted, reimplemented in C.

Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (process-define-module): Modified to handle both
        keywords and symbols.

Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * slib.scm: update read usage.

        * r4rs.scm: update primitive-load usage.
        Don't define read-sharp.

        * boot-9.scm: use read-hash-extend to install extra read syntax.
        (read-sharp): removed.
        Adjust usage of primitive-load-path, read, which no longer take
        case_i or read-sharp arguments.

Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm: Added loading of session support module.

        * debug.scm: Removed `display-application'.  (Replaced by
        primitive procedure.)

        * boot-9.scm (beautify-user-module!): Don't add the root module
        interface to the end of the use-list of the root module.

Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.

Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm: check use-emacs-interface for emacs support.

Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (scm-style-repl): call repl-report-start-timing if
        read gets EOF.
        * (exit): alias for quit.

Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (error-catching-loop thunk): use a status variable to
        return the quit args.
        (scm-style-repl): call -quit, passing return value from
        error-catching-repl.  Make -quit return its args.
        stand-alone-repl: comment out, since it seems unused.

        (error-catching-loop thunk): discard trailing junk after a (quit).

Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm: Removed the old printer code.

        * r4rs.scm (apply, call-with-current-continuation): Added comment
        explaining why apply and call/cc need to be closures.

        * boot-9.scm (apply, call-with-current-continuation): Bugfix:
        Removed. These definitions are already present in r4rs.scm.

        * debug.scm (trace-entry, trace-exit): Check that we're on a repl
        stack before printing traced frames; Re-enable trace flag at end
        of handlers.

Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * debug.scm: Add hook for reset of trace level at abort.

        * boot-9.scm (run-hooks): New procedure.
        (add-hooks!): New macro.
        Change hooks to use these functions.

        * debug.scm: *Warning* This feature is a bit premature.  I add
        it anyway because 1. it is very useful, and, 2. you can start
        making it less premature by complaining to me and by modifying
        the source! :-)
        (trace): Given one or more procedure objects, trace each one.
        Given no arguments, show all traced procedures.
        (untrace): Given one or more procedure objects, untrace each one.
        Given no arguments, untrace all traced procedures.  The tracing in
        Guile have an advantage to most other systems: We don't create new
        procedure objects, but mark the procedure objects themselves.
        This means that also anonymous and internal procedures can be
        traced.

        * boot-9.scm (error-catching-loop): Added handling of apply-frame
        and exit-frame exceptions.
        
        * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
        (set-repl-prompt!): Setter for repl prompt.
        (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
        string, display it; if prompt is a thunk, call it and display its
        result; otherwise display "> ".
        (Change suggested by Roland Orre <orre@nada.kth.se>.)

        * r4rs.scm (%load-verbosely): Reverted change to
        `module-defined?', since the module system isn't bootstrapped when
        we load r4rs.scm.  This is just a temporary fix to make the
        repository version runnable.

Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm: Removed the enabling of debug evaluator and
        recording of source code positions.  This was placed there for our
        convenience, but it has already sneaked into the distribution
        once... so we'd better add this in our local copies instead when
        we need it.  (These options are normally enabled at the end of
        boot-9.scm when loading the debug module.)

Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (module-defined?): New function.
        (macroexpand-1, macroexpand): Use local-ref instead of defined?
        and eval.
        * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
        "defined?".
        * slib.scm (defined?): New function to take the place of the
        builtin "defined?".  It allways examines the slib module.

Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * configure.in: Added AM_MAINTAINER_MODE

Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (read-sharp): define directly, don't go through a
        %read-sharp layer.

Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
        uniform-vector-set1! which doesn't exist.

Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>

        * boot-9.scm (backtrace): Removed.  (A C version now exists in
        backtrace.c.)

Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (read-line!, read-delimited!, read-delimited,
        read-line): new procedures, see libguile/ChangeLog.

Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>

        Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.

        * boot-9.scm (split-c-module-name, convert-c-registered-modules,
        init-dynamic-module, dynamic-maybe-call,
        find-and-link-dynamic-module, link-dynamic-module,
        try-module-dynamic-link, registered-modules): New definitions for
        dynamic linking of modules.
        (resolve-module): Try to dynamically link the requested module
        after failing to load it as Scheme code.

Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (getservbyport, getservbyname): remove stray %.

Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
        that's what it is.

        * lineio.scm (make-line-buffering-input-port): Properly test for
        the case of an empty buffer list.  The old code assumed that '()
        was false.

Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>

        * boot-9.scm (use-modules): New macro (from Marius Vollmer).
        (use-modules <module name> ...) Put the the modules named by
        <module name> ... on the use list of the current module.

Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm (error-catching-loop): Remove message saying that
        typing "$" will put you in the debugger.  This isn't implemented
        yet.

Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
        been fixed, so this function is superfluous.
        (transform-usage-lambda): Use delq!, not delq-all!.

Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (resolve-module): New optional parameter that
        controls whether autoloading is attempted or not. Default is #t.
        (process-define-module): Don't autoload the defined module.
        (try-module-autoload): Don't autoload the directory modules.

        * boot-9.scm (process-define-module): Ensure that the-scm-module
        is last in the `uses' list to allow shadowing builtin
        bindings. All :use-module options are added in the order they
        appear in the arguments but before anything already on the list
        (such as the-scm-module).

Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * slib.scm (slib-parent-dir): throw error if #f returned from
        %search-load-path.

Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>

        * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
        * Makefile.am, aclocal.m4: New files.
        * configure.in: Updated for Automake.

Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>

        * boot-9.scm (macroexpand-1, macroexpand), slib.scm
        (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
        function, use it accordingly.
        
Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>

        It's an "eval closure", not an "eval thunk."  A thunk is a
        function of no arguments.
        * boot-9.scm (module-type): Rename module field.
        (make-module, eval-in-module, make-root-module,
        set-current-module): Uses changed. 
        (module-eval-closure, set-module-eval-closure!,
        root-module-closure): Renamed from module-eval-thunk,
        set-module-eval-thunk!, root-module-thunk.
        (set-current-module): Change uses of *top-level-lookup-thunk* to
        *top-level-eval-closure*.

Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>

        * slib.scm (slib-parent-dir): Use string-length, not length.
        (Thanks to Bernard Urban.)

Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm: The debugging evaluator and recording of positions
        aren't enabled by default any longer (they are switched on in
        debug.scm).  But during development we want to have them also
        *inside* boot-9.scm.  Therefore, two lines are added at the
        beginning of boot-9.scm to enable these.
        
        Call `provide' so that `records' are included among the
        `*features*'.
        
        The scheme for saving the stack has been adjusted: save-stack is
        now commonly available for saving the stack.  Calling `save-stack'
        sets a flag `stack-saved?' which prevents overwriting the stack.
        `stack-saved?' is reset at `abort'.
        
        Spelling correction: seperate --> separate.
        
        Removed `:'s that had creeped into some comments.
        
        The repl now doesn't print #<unspecified> results any longer
        If the user wants to see this, he can do
        (assert-repl-print-unspecified #t) in his startup file.
        
        The user now gets a friendly message instead of a backtrace at
        error.
        
        Added `before-read-hook'.
        
        Load module (ice-9 emacs) if option `-e' was specified.
        
        (provide): New function.
        
        (error): Save stack at entry, so that Guile entrails won't show up
        in backtraces.
        
        (backtrace): New function.
        
        (save-stack): Can now take arbitrary number of stack narrowing
        specifier pairs.  The first specifier in a pair controls inner
        border, the second the outer border.  A number means cut that
        number of frames, a procedure object means cut until that object
        is found in operator position in a frame.

        * debug.scm: Enable debugging evaluator and recording of positions
        by default.

        * slib.scm (slib:load): Adapt to the new behavior of
        primitive-load: It doesn't any longer try both with and without
        ".scm" extension.  (We don't want to use %search-load-path here.)
        
        (implementation-vicinity): New function.  slib requires it
        
        (library-vicinity): Updated.
        
        Load "require.scm" in the library-vicinity.
        
        (install-require-vicinity, install-require-module): New functions.
        
Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm (load-from-path): New function.

        * boot-9.scm (try-load, basic-try-load, try-load-module,
        try-load): Deleted.  I don't think they're being used.

        * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
        so they'll get distributed.

        Get Guile to be a little less chatty by default.  The new user
        should see as little clutter as possible.
        * r4rs.scm (%load-verbosely): Make this #f by default.
        * boot-9.scm (scm-repl-verbose): Make this #f by default.
        (scm-style-repl): Don't run 'pk' on the value passed to quit.

        * r4rs.scm: New file.
        * boot-9.scm: Load r4rs.scm, first thing.
        (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
        open-output-file, open-io-file, close-input-port,
        close-output-port, close-io-port, call-with-input-file,
        call-with-output-file, with-input-from-port, with-output-to-port,
        with-error-to-port, with-input-from-file, with-output-to-file,
        with-error-to-file, with-input-from-string, with-output-to-string,
        with-error-to-string, the-eof-object): Definitions moved to
        r4rs.scm.  Not all of them are R4RS, but those that are use those
        that are not.
        (load, %load-verbosely, %load-announce): Moved, along with code to
        set %load-hook, to r4rs.scm.

        * test.scm: New file.

        * boot-9.scm (integer?): Definition deleted, in favor of the one
        present in libguile (which used to be called int?).  I have no
        idea why integer? didn't just call int? to begin with.

        * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
        =?, >?, and >=? deleted; they're defined that way by libguile now.

        * boot-9.scm (load): Simplified; primitive-load does most of this
        work now.
        (%load-announce-win): Removed; no longer used.  Set %load-hook to
        call %load-announce.

Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
        stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
        stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
        components.
        (file-is-directory?): use stat:type.

Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
        that's now taken care of in libguile, and in a way compatible with
        SCSH (which this isn't).

Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>

        * boot-9.scm: Formatting tweaks.

Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

        * boot-9.scm (handle-system-error): Added hooks before-error-hook,
        after-error-hook, before-backtrace-hook and after-backtrace-hook
        to the error handler.  E.g.: fancy emacs support could plug into
        these.
        (save-stack): New function.  The stack is now made differently
        depending on the stack id.  (The motivation is to make a better
        choice regarding what stack frames to present to the user.)
        (error-catching-loop): Stack handling code moved outside into
        save-stack.

Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * Makefile.in (scm_files): add expect.scm.

        * expect.scm: new file ported from guile-iii.

        * boot-9.scm: remove handle-system-error, after moving the code into
        error-catching-loop.
        Don't set 'throw-handler-default property on error keys.
        Just interpret (almost) any throw with 4 args as an error throw.
        Delete some try-load stuff that was already commented out.

        Second thoughts, keep handle-system-error but call it from
        error-catching-loop.

Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm: Doc fixes.
        (make-module): Rework for readability.
        (make-root-module, make-scm-module): USES argument to make-module
        should be '(), not #f.

        * boot-9.scm (try-load): %sys-load-path has been renamed to
        primitive-load-path; adjust call here.

Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

        * boot-9.scm (signal-handler): Bugfix: Moved the recording of
        the stack to the correct place: when it is decided to generate an
        error-signal.

Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

        * boot-9.scm (error-catching-loop, signal-handler,
        handle-system-error): Backtracing now works for signals aswell;
        Backtracing mechanism can now identify the stack root created by
        start-stack so that the user isn't exposed to system stack frames.

Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

        * Makefile.in: Added threads.scm.
        
Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

        * debug.scm (make-enable, make-disable): Simplified.

        * boot-9.scm: Renamed %%throw-handler-default -->
        throw-handler-default.
        ((handle-system-error key . arg-list)): Changed the way errors are
        reported.
        ((scm-style-repl)): Wrap up the call to eval in a start-stack
        acro.
        ((error-catching-loop thunk)): Introduce a lazy-catch into

Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>

        * mapping.scm (hash-table-mapping): Explicitly request that
        make-vector fill new vectors with '(); this will make it easier to
        port Guile Scheme code to other Schemes.
        * boot-9.scm (make-print-style, make-print-table): Same.

Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (load): rewritten again.
        Append "." to the default %load-path.
        (feature?): new function: checks for a symbol in the features list.
        (module-local-variable): remove apparently useless (caddr (list m v
        ...))
        (%load-announce): minor formatting change.
        (file-exists?): use access? if posix is featured.
        (file-is-directory?): use stat if i/o-extensions is featured.
        (try-module-autoload module-name): use file-exists? before 
        file-is-directory?

Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>

        * boot-9.scm: Added conditional loading of threads.scm.

        * threads.scm: New file.  Modified from the Cygnus-r0.3
        distribution.

        * boot-9.scm (error-catching-loop): Added handling of key
        `switch-repl'.

        * boot-9.scm: Name change %%bad-throw --> bad-throw.

Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>

        * boot-9.scm (make-record-type, record-constructor): Don't assume
        the empty list is false when parsing the argument list.

Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>

        * boot-9.scm (signal-handler): Clean up logic.

        * boot-9.scm (load): Assume %load-path is always bound.

Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (error): replace another throw with scm-error.  Throw
        to 'misc-error instead of 'error (no need to distinguish these.)
        Don't set up 'error as a key.
        Set up regex-error as a key, if regex is available.
        (signal-handler): use scm-error, not throw.

        (%try-load, try-load-with-path, %load, load-with-path,
        basic-try-load-with-path, basic-load-with-path,
        try-load-module-with-path,load-module-with-path): deleted, since
        they seem redundant.
        (try-load): define using %try-load, not try-load-with-path.
        (load): rewritten.  load tries to open the file directly and
        with a .scm extension before searching the library directories
        (should "." be added to %load-path?  then load could still open
        directly files starting with "/").
        (try-module-autoload): use load, not load-with-path.
        (%load-indent): deleted, -2 was causing errors.

        (%read-sharp): use port-line, not line-number.

Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>

        * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
        straightforward to provide the equivalent functionality using
        (catch #t ...), so there's no need for the extra complexity.  2)
        Outside the context of a read-eval-print loop (which Guile should
        not require) it's not clear we should do anything more complicated
        than print an error and exit; the user or REPL can establish
        something better if it wants.  3) In that case, it's much more
        robust to just do it in the C code.

Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (%try-load): define using primitive-load.  Previously
        %try-load itself was the primitive.
        (load-with-path): use scm-error instead of %load-announce-lossage.
        Errors are thrown to 'misc-error instead of 'could-not-load.
        (%load-announce-lossage): deleted.

Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>

        * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
        (make-record-type type-name fields): Temporarily remove support
        for printing of records (not possible yet with C printer).

Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (file-exists?, file-is-directory): catch only
        system-error, not every kind of error.
        (scm-error): new procedure.

Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>

        * boot-9.scm: Formatting tweaks.

Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (%%handle-system-error key): remove the code for
        SCM-style errors.  handle the case that an unexpected number
        of args are supplied.
        (%%system-errors): removed.
        (error): redefine using a throw with key and 4 args.
        ('error): associate 'error, 'error-signal keys with
        %%handle-system-error.
        (%%default-error-handler): removed.
        (signal-handler): throw with 4 args and use the error-signal key.
        Create an error message instead of using numerical codes.
        (%%bad-throw): call error instead of throw if key not found.

Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
        (%%handle-system-error key): check subr is not #f before printing.
        Recognize %s (embed an argument using "display") and
        %S (embed an argument using "write").

Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (%%handle-system-error key): set args and rest to
        the empty list if they are #f.
        Initialize out-of-range as an error key.

Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.

        * boot-9.scm: remove leading %% from references to '%%system-error.
        (%%handle-system-error): don't pass all the thrown arguments when
        aborting, just the key and subr.
        Remove the code to "Install default handlers for built-in errors."
        Remove the definition of the syserror procedure.
        Associate 'numerical-overflow with default handler.

Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

        * boot-9.scm: Name change: value-ref --> local-ref
        resolved-ref --> nested-ref  Motivation: conformance to the other
        dictionary operators: list-ref operates on list, vector-ref
        operates on vector, nested-ref operates on nested namespace,
        local-ref operates on the local nested namespace.

Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm (%%handle-system-error): recognise errors thrown
        by lgh-error (fill-message etc.)
        (fill-message): check first whether args is null.
        (fill-message): bug fix and check that args is a list.

Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>

        * boot-9.scm: %load-path is initialized in C code now.
        (implementation-vicinity, parse-path): Deleted, along with code to
        initialize %load-path.

        * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
        "/", use one to separate it from the file.

Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>

        * boot-9.scm (%load-path): Add the site directory.
        Add the directory named after the version number.
        Prepend the version number to the other directories in the path.
        Simplify by mapping the common prefix onto each item.
        * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
        sitedatadir): New definitions.
        (libparent, libdir, install_path): Replaced by above.
        (install): Create the above directories.
        Put the source files into subpkgdatadir.
        (uninstall): Remove the above directories.

Thu Aug 29 21:48:47 1996  Jim Blandy  <jimb@floss.cyclic.com>

        Don't use the PLUGIN system to gather information for the
        Makefile's distribution and installation targets; just put it all
        in the Makefile directly.
        * PLUGIN/this.configure (scm_files, aux_files): Remove sections
        for these.
        * configure.in: Remove code that gets and substitutes scm_files and
        aux_files.
        * Makefile.in (scm_files, aux_files): Write out the list of files
        here, where people expect to find them.

Fri Aug 23 06:44:36 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

        * boot-9.scm: Preliminary solution: optionally load the debug
        module.  Changed "gls" to "guile1.0b3".

        * debug.scm: New file: debug extensions.

Wed Aug 21 13:06:56 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

        * boot-9.scm (print-vector): Renamed weak-hash-table? -->
        weak-key-hash-table?.  (Again!)

        * boot-9.scm (*null-device*): global constant from goonix.
        (move->fdes): adjusted for boolean primitive-move->fdes.  return
        the modified port, always set revealed count to 1 (SCSH compatible).

        (%open-file): removed.
        (open-input-file, open-output-file, file-exists?, file-is-directory?):
        modified for open-file change (does not return #f).

        * Makefile.in (dist-dir): New target for new dist system.
        (manifest): Deleted.
        * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a
        directory, and needs special treatment in the dist-dir target.

Thu Aug  1 09:00:21 1996  Gary Houston  <ghouston@actrix.gen.nz>

        * boot-9.scm: remove the wrappers for '%' system primitives,
        now that they throw errors directly.
