Changes in 2.0.1 (since 2.0.0):
+* Notable changes
-
-* New modules (see the manual for details)
-
-** `(ice-9 binary-ports)', XXX
+** guile.m4 supports linking with rpath
-* Memory leak fixes
+The GUILE_FLAGS macro now sets GUILE_LIBS and GUILE_LTLIBS, which
+include appropriate directives to the linker to include libguile-2.0.so
+in the runtime library lookup path.
-close-port leaking iconv_t
+** `begin' expands macros in its body before other expressions
-weak hash table pumping
+This enables support for programs like the following:
-* doc work
+ (begin
+ (define even?
+ (lambda (x)
+ (or (= x 0) (odd? (- x 1)))))
+ (define-syntax odd?
+ (syntax-rules ()
+ ((odd? x) (not (even? x)))))
+ (even? 10))
-goops mop
-
-* guile.m4 supports linking with rpath
-
- * guile.m4 (GUILE_FLAGS): Also set GUILE_LIBS and GUILE_LTLIBS. Fix
- documentation.
+** REPL reader usability enhancements
-* Add omitted exports from `(ice-9 vlist)'.
-
- * module/ice-9/vlist.scm: Export `vhash-delq' and `vhash-delv'.
+The REPL now flushes input after a read error, which should prevent one
+error from causing other errors. The REPL also now interprets comments
+as whitespace.
-* re-enable the after-gc-hook
-
-* chi-top-sequence defines macros before expanding other exps
-
-(begin
- (define even?
- (lambda (x)
- (or (= x 0) (odd? (- x 1)))))
- (define-syntax odd?
- (syntax-rules ()
- ((odd? x) (not (even? x)))))
- (even? 10))
+** REPL output has configurable width
-* flush all input on a read error
-
- * module/system/repl/repl.scm (flush-all-input): New helper.
- (prompting-meta-read): Flush all input on a read error, as we could be
- within some expression or a string or something.
-
-* repl.scm understands comments
-
- * module/system/repl/repl.scm (read-comment, read-scheme-line-comment)
- (read-scheme-datum-comment): New helpers.
- (meta-reader): Take a language instead of a reader. If we have a
- nonwhitespace char, first check to see that it's a comment, and if so,
- read it off and loop.
- (prompting-meta-read): Call meta-reader with the lang.
-
-* Add ,width meta-command to set screen width in debug output
-
-terminal-width by default
-
-* man page updates
-
-Mark Harig
-
-* add ice-9 eval-string
-
-Fly Evaluation in the manual

- * libguile/modules.c (scm_public_lookup, scm_private_lookup)
- (scm_c_public_lookup, scm_c_private_lookup, scm_public_ref)
- (scm_private_ref, scm_c_public_ref, scm_c_private_ref)
- (scm_public_variable, scm_private_variable, scm_c_public_variable)
- (scm_c_private_variable): New helpers to get at variables and values
- in modules.
+The REPL now defaults to output with the current terminal's width, in
+columns. See "Debug Commands" in the manual for more information on
+the ,width command.
-"Accessing Modules from C" in the manual
-
-* add scm_call_{5,6}
-
- * doc/ref/api-evaluation.texi (Fly Evaluation): Document
- scm_call_{5,6,n}.
-
-* Add scm_from_latin1_keyword and scm_from_utf8_keyword
-
- * doc/ref/api-data.texi: Document new functions. Remind users that
- scm_from_locale_keyword should not be used when the name is a C string
- constant. Change formal parameter from `str' to `name'.
-
-* srfi-9 define-record-type in nested contexts
-
-* Add `get-string-n' and `get-string-n!' for binary and R6RS ports
-
-* rnrs io ports work
-
-Export `current-input-port', `current-output-port' and
-`current-error-port'.
-
- Enhance transcoder-related functionality of `(rnrs io ports)'
-
- * module/rnrs/io/ports.scm (transcoder-eol-style)
- (transcoder-error-handling-mode): Export these.
- (textual-port?): Implement this procedure and export it.
- * module/rnrs.scm: Export these here as well.
-
- * module/rnrs/io/ports.scm (port-transcoder): Implement this procedure.
- (binary-port?): Treat only ports without an encoding as binary ports,
- add docstring.

-
- * test-suite/tests/r6rs-ports.test (7.2.7 Input ports)
- (8.2.10 Output ports): Test binary-ness of `standard-input-port',
- `standard-output-port' and `standard-error-port'.
- (8.2.6 Input and output ports): Add test for `port-transcoder'.
-
- doc: Remove "lack of support for Unicode I/O and strings".
-
- * doc/ref/api-io.texi (R6RS I/O Ports): Remove 1.8ish comment.
-
-* add pointer->scm, scm->pointer
-
- * libguile/foreign.c (scm_pointer_to_scm, scm_scm_to_pointer): New
- functions, useful to pass and receive SCM values to and from foreign
- functions.
-
- * module/system/foreign.scm: Export the new functions.
-
- * doc/ref/api-foreign.texi (Foreign Variables): Add docs.
+** Better C access to the module system
-* gc-stats update
+Guile now has convenient C accessors to look up variables or values in
+modules and their public interfaces. See `scm_c_public_ref' and friends
+in "Accessing Modules from C" in the manual.
-add heap-allocated-since-gc; fix ,stat.
+** Added `scm_call_5', `scm_call_6'
-* allow ,option on-error report instead of debug
-
-"System Commands" in the manual.
+See "Fly Evaluation" in the manual.
-* Make VM string literals immutable.
+** Added `scm_from_latin1_keyword', `scm_from_utf8_keyword'
-* don't redirect pthread_create et al
+See "Keyword Procedures" in the manual, for more. Note that
+`scm_from_locale_keyword' should not be used when the name is a C string
+constant.
- * libguile/bdw-gc.h: Don't do pthread redirects, because we don't want
- to affect applications' pthread_* bindings.
-
- * libguile/pthread-threads.h (scm_i_pthread_create)
- (scm_i_pthread_detach, scm_i_pthread_exit, scm_i_pthread_cancel)
- (scm_i_pthread_sigmask): Do pthread redirects here, in this internal
- header.
+** R6RS unicode and string I/O work
-* Document SRFI-23
-
- * doc/ref/srfi-modules.texi: mention that we support SRFI 23
- * module/ice-9/boot-9.scm (%cond-expand-features): add srfi-23
+Added efficient implementations of `get-string-n' and `get-string-n!'
+for binary ports. Exported `current-input-port', `current-output-port'
+and `current-error-port' from `(rnrs io ports)', and enhanced support
+for transcoders.
-* with-continuation-barrier calls exit(3) _after_ unwinding
+** Added `pointer->scm', `scm->pointer' to `(system foreign)'
- * libguile/continuations.c (scm_handler, c_handler)
- (scm_c_with_continuation_barrier, scm_with_continuation_barrier):
- Instead of calling scm_handle_by_message_noexit in the pre-unwind
- handler, roll our own exception printing in the pre-unwind, and do to
- exit()-on-quit in the post-unwind handler. This lets the stack unwind
- at exit-time so that pending dynwinds run.
-
- * test-suite/tests/continuations.test ("continuations"): Add a test.
-
-* string->pointer and pointer->string have optional encoding arg
+These procedure are useful if one needs to pass and receive SCM values
+to and from foreign functions. See "Foreign Variables" in the manual,
+for more.
-"Void Pointers and Byte Access" in the manual.
+** Added `heap-allocated-since-gc' to `(gc-stats)'
-* Several optimizations for R6RS fixnum arithmetic
+Also fixed the long-standing bug in the REPL `,stat' command.
-* Move `define-inlinable' into the default namespace
+** Add `on-error' REPL option
- * module/ice-9/boot-9.scm (define-inlineable): Moved here from SRFI-9.
- * module/srfi/srfi-9 (define-inlinable): Removed here.
-
- * doc/ref/api-procedures.texi (Inlinable Procedures): Add subsection
- about `define-inlinable'.
-
-* Implement R6RS' `fixnum?' in a smarter way
-
- * module/rnrs/arithmetic/fixnums.scm (fixnum?): Implemented using
- bit-twiddling, and using `define-inlinable'.
+This option controls what happens when an error occurs at the REPL, and
+defaults to `debug', indicating that Guile should enter the debugger.
+Other values include `report', which will simply print a backtrace
+without entering the debugger. See "System Commands" in the manual.
-commit 882c89636a2a4afa26cff17c7cdbc1d8c1cb2745
-Author: Mark H Weaver <mhw@netris.org>
-Date: Wed Apr 6 15:09:42 2011 -0400
+** Enforce immutability of string literals
- Fix the R6RS exact-integer-sqrt and import into core guile
-
- * libguile/numbers.c (scm_exact_integer_sqrt): New C procedure to
- compute exact integer square root and remainder.
- (scm_i_exact_integer_sqrt): New Scheme procedure `exact-integer-sqrt'
- from the R6RS, imported into core guile.
-
- * libguile/numbers.h: Add prototypes.
+Attempting to mutate a string literal now causes a runtime error.
- * module/rnrs/base.scm: Remove broken stub implementation, which would
- fail badly when applied to large integers.
+** Fix pthread redirection
+
+Guile 2.0.0 shipped with headers that, if configured with pthread
+support, would re-define `pthread_create', `pthread_join', and other API
+to redirect to the BDW-GC wrappers, `GC_pthread_create', etc. This was
+unintended, and not necessary: because threads must enter Guile with
+scm_with_guile, Guile can handle thread registration itself, without
+needing to make the GC aware of all threads. This oversight has been
+fixed.
+
+** `with-continuation-barrier' now unwinds on `quit'
+
+A throw to `quit' in a continuation barrier will cause Guile to exit.
+Before, it would do so before unwinding to the barrier, which would
+prevent cleanup handlers from running. This has been fixed so that it
+exits only after unwinding.
- * doc/ref/api-data.texi: Add documentation.
+** `string->pointer' and `pointer->string' have optional encoding arg
- * doc/ref/r6rs.texi: Change documentation for `exact-integer-sqrt' to a
- stub that xrefs the core docs, as is done for other operations
- available in core.
-
- * test-suite/tests/numbers.test: Add tests.
-
- * NEWS: Add news entries.

-commit adf43b3f081878860ed1d4d5091b9a432b44da90
-Author: Andy Wingo <wingo@pobox.com>
-Date: Mon Apr 11 10:13:48 2011 +0200
+This allows users of the FFI to more easily deal in strings with
+particular (non-locale) encodings, like "utf-8". See "Void Pointers and
+Byte Access" in the manual, for more.
- ignore SIGPIPE in (system repl server)
+** R6RS fixnum arithmetic optimizations
- * module/system/repl/server.scm (run-server): Ignore SIGPIPE when we run
- a server, as otherwise a rudely disconnected client could cause the
- server to quit. Thanks to John Proctor for the report, and Detlev
- Zundel for the debugging.
+R6RS fixnum operations are are still slower than generic arithmetic,
+however.
-commit 15671c6e7fd86160b415b5373b2c1539e23556f3
-Author: Andy Wingo <wingo@pobox.com>
-Date: Mon Apr 11 11:52:35 2011 +0200
-
- refactor scm_i_print_symbol_name
+** New procedure: `define-inlinable'
- * libguile/print.c (symbol_has_extended_read_syntax)
- (print_normal_symbol, print_extended_symbol, scm_i_print_symbol_name):
- Factor scm_i_print_symbol_name into separate routines. Add comments.
- There are a number of bugs here.
+See "Inlinable Procedures" in the manual, for more.
-commit d9527cfafdad1046770437a7a59d3745e7243c67
-Author: Andy Wingo <wingo@pobox.com>
-Date: Mon Apr 11 12:48:06 2011 +0200
+** New procedure: `exact-integer-sqrt'
- read-extended-symbol handles backslash better, including r6rs hex escapes
-
- * libguile/read.c (scm_read_extended_symbol): Interpret '\' as an escape
- character. Due to some historical oddities we have to support '\'
- before any character, but since we never emitted '\' in front of
- "normal" characters like 'x' we can interpret "\x..;" to be an R6RS
- hex escape.
+See "Integer Operations" in the manual, for more.
- * test-suite/tests/reader.test ("#{}#"): Add tests.
+** "Extended read syntax" for symbols parses better
-commit 2e9fc9fc73a8157152e6b2e122ec545d96478c2a
-Author: Andy Wingo <wingo@pobox.com>
-Date: Mon Apr 11 13:38:27 2011 +0200
+In #{foo}# symbols, backslashes are now treated as escapes, as the
+symbol-printing code intended. Additionally, "\x" within #{foo}# is now
+interpreted as starting an R6RS hex escape. This is backward compatible
+because the symbol printer would never produce a "\x" before. The
+printer also works better too.
- symbols with odd characters print better in #{}#
-
- * libguile/print.c (symbol_has_extended_read_syntax): Use a more
- general, unicode-appropriate algorithm. Hopefully doesn't cause
- any current #{}# cases to be unescaped.
- (print_extended_symbol): Use more appropriate unicode algorithm, and
- emit unicode hex escapes instead of our own lame escapes.
-
- * test-suite/tests/symbols.test: Add tests.
+* Manual updates

-
- * module/ice-9/psyntax-pp.scm: Regenerate, to take advantage of better
- #{}# serialization.
+** New man page
