Changes in 2.0.4 (since 2.0.3):
-* Features
+* Notable changes
-** Better debuggability for interpreted procedures
+** Better debuggability for interpreted procedures.
Guile 2.0 came with a great debugging experience for compiled
procedures, but the story for interpreted procedures was terrible. Now,
** SRFI-39 parameters are available by default.
-Guile now includes support for "parameters", as defined by SRFI-39, in
-the default environment. See
- * module/ice-9/boot-9.scm (<parameter>, make-parameter, parameter?)
- (parameter-fluid, parameter-converter, parameterize): New top-level
- bindings, implementing SRFI-39 parameters. Currently,
- current-input-port and similar procedures are not yet parameters.
-
-** add current-warning-port
+Guile now includes support for parameters, as defined by SRFI-39, in the
+default environment. See "Parameters" in the manual, for more
+information. `current-input-port', `current-output-port', and
+`current-error-port' are now parameters.
- * libguile/ports.h:
- * libguile/ports.c (scm_current_warning_port)
- (scm_set_current_warning_port): New functions, wrapping the Scheme
- parameter.
+** Add `current-warning-port'
- * module/ice-9/boot-9.scm (current-warning-port): New parameter,
- defining a port for warnings.
+Guile now outputs warnings on a separate port, `current-warning-port',
+initialized to the value that `current-error-port' has on startup.
- warnings written to warning port
-
- * libguile/deprecation.c (scm_c_issue_deprecation_warning):
- * libguile/load.c (auto_compile_catch_handler):
- (scm_sys_warn_auto_compilation_enabled, scm_primitive_load_path):
- * module/ice-9/boot-9.scm (warn, %load-announce, duplicate-handlers)
- (load-in-vicinity):
- * module/system/base/message.scm (warning): Write to the warning port.
- (*current-warning-port*): Alias the warning port.
+** Syntax parameters.
+Following Racket's lead, Guile now supports syntax parameters. See
+"Syntax parameters" in the manual, for more.
-** add define-syntax-parameter, same as define-syntax
+Also see Barzilay, Culpepper, and Flatt's 2011 SFP workshop paper,
+"Keeping it Clean with syntax-parameterize".
- * module/ice-9/psyntax.scm (define-syntax-parameter): New toplevel form.
- Will be used to implement syntax parameters, following Barzilay,
- Culpepper, and Flatt's 2011 SFP workshop paper, "Keeping it Clean with
- syntax-parameterize". Adds a new binding type and definition form.
-** deprecate fluid-let-syntax in favor of syntax-parameterize
+`primitive-load' returns the values yielded from evaluating the last
+expression in the file. This in turn makes `load' always return the
+results of the last expression, both when interpreted and compiled.
- * module/ice-9/psyntax.scm (syntax-parameterize): Rename from
- fluid-let-syntax.
+** Parse command-line arguments from the locale encoding.
-Author: Ian Price <ianprice90@googlemail.com>
-Date: Sat Jan 7 01:59:33 2012 +0000
+Guile now attempts to parse command-line arguments using the user's
+locale. However for backwards compatibility with other 2.0.x releases,
+it does so without actually calling `setlocale'. Please report any bugs
+in this facility to bug-guile@gnu.org.
- document syntax parameters
-
- * doc/ref/api-macros.texi (Macros): Add subsection for "Syntax Parameters"
+* New interfaces
+
+** (ice-9 session): `apropos-hook'
+** New print option: `escape-newlines', defaults to #t.
+** (ice-9 ftw): `file-system-fold', `file-system-tree', `scandir'
-** primitive-load returns the value(s) of the last expression
-
- * libguile/load.c (scm_primitive_load): Return the values yielded from
- evaluating the last expression in the file.
-
* Bug fixes
** Fix R6RS `fold-left' so the accumulator is the first argument.
** fix <dynwind> serialization.
-** Fix bugs in the new optimizer.
-
-The new `peval' optimizer had three bugs: one related to dynamic-wind,
-one regarding propagation of expressions that yield multiple values, and
-one that would mistakenly turn (cons 'foo #nil) into (list 'foo). These
-were fixed.
-
-** when leaving a non-tail let, allow bound vals to be collected
-
- * module/language/tree-il/compile-glil.scm (flatten-lambda-case): Clear
- lexical stack slots at the end of a non-tail let, letrec, or fix.
- Fixes http://debbugs.gnu.org/9900.
-
-** fix bit-set*! bug (!)
-
- * libguile/bitvectors.c (scm_bit_set_star_x): Fix a long-standing (since
- 2005) bug in which instead of using the kv bitvector, we actually use
- the `v' bitvector. Also, change to allow `kv' being shorter than
- `v'.
-
-** fix bug in make-repl when lang is actually a language
-
- * module/system/repl/common.scm (make-repl): Fix to accept language
- objects in addition to symbols. Fixes http://debbugs.gnu.org/9857.
- Thanks to Tristan Colgate for the report.
-
-** hack the port-column of current-output-port after printing a prompt
-
- * module/ice-9/boot-9.scm (repl-reader): Reset the output-column to 0
- after printing the prompt. Fixes bug 9664.
-
+** Fix bugs in the new `peval' optimizer.
+** Allow values bound in non-tail let expressions to be collected.
+** Fix bit-set*! bug from 2005.
+** Fix bug in `make-repl' when `lang' is actually a language.
+** Hack the port-column of current-output-port after printing a prompt.
** FFI: Hold a weak reference to the CIF made by `procedure->pointer'.
-
- * libguile/foreign.c (scm_procedure_to_pointer): Keep a weak reference
- to CIF so that it is not reclaimed before POINTER. Before that it
- could be reclaimed and typically reused to store the CIF of another
- procedure with the same arity, leading to obscure wrong-type-arg
- errors.
-
+** FFI: Hold a weak reference to the procedure passed to `procedure->pointer'.
+** FFI: Properly unpack small integer return values in closure call.
** Allow overlapping regions to be passed to `bytevector-copy!'.
-
- Reported by Dmitry Chestnykh <dmitry@codingrobots.com>.
- Fixes <http://debbugs.gnu.org/10070>.
-
** Fix `validate-target' in (system base target).
-
- * module/system/base/target.scm (validate-target): Accept any tuple with
- at least 3 parts.
-
-** fix validators for various list-style headers
-

- (validate-credentials): Validate param for Basic scheme, which
- is parsed as a string.
- (declare-symbol-list-header!): `list-of?' args were in wrong order.
- ("Cache-Control"): Replace `default-val-validator' with more
- specific procedure.
- ("Accept"): Validate on first param which has no value.
-
-** FFI: Hold a weak reference to the procedure passed to `procedure->pointer'.
-

- to PROC.
-
- * test-suite/tests/foreign.test ("procedure->pointer")["procedure is
- retained"]: New test.
-

- * module/system/repl/repl.scm (start-repl): Create a new dynamic scope
- for *current-language*.
-
-** new print option escape-newlines, defaults to #t
-
- * libguile/private-options.h (SCM_PRINT_ESCAPE_NEWLINES_P):
- * libguile/print.c: Add new escape-newlines print option, defaulting to
- on.
- (write_character): For newlines, if SCM_PRINT_ESCAPE_NEWLINES_P, then
- print them as \n.
- (scm_init_print): Refactor print options initialization.

-
- Reported by Cédric Cellier <rixed@happyleptic.org>.
-
+** `,language' at REPL sets the current-language fluid.
+** `primitive-load' returns the value(s) of the last expression.
** Add an exception printer for `getaddrinfo-error'.
-
- * module/ice-9/boot-9.scm (getaddrinfo-error-printer): New procedure.
- Use it as the `getaddrinfo-error' exception printer.
-
-** current-input-port et al are srfi-39 parameters
-
-** add an apropos-hook to ice-9 session
-
- * module/ice-9/session.scm: #:keyword-ify the define-module form, and

- `file-system-tree' and `file-system-fold'.
-
-** Arrange to convert command-line arguments from the right encoding.
-
- This is a temporary workaround for the 2.0 stable series. The next
- stable series should have an implicit `setlocale (LC_ALL, "")' call,
- which will make this unnecessary.
-
- * libguile/feature.c (progargs_fluid): Rename to...
- (scm_program_arguments_fluid): ... this. Update users.

-
-** fix generalized-vector-{ref,set!} for slices
-
- * libguile/generalized-vectors.c (scm_c_generalized_vector_ref):

-commit ab66fb3cd1d6e4343741ccb406e17eb3314eba84
-Author: Ian Price <ianprice90@googlemail.com>
-Date: Thu Sep 29 03:12:00 2011 +0100
-
- * module/web/http.scm (write-request-line): RFC 2616 says that absolute
- paths are used to identify resources on an origin server.
-
-** don't leak file descriptors when mmaping objcode
-
- * libguile/objcodes.c (make_objcode_from_file): Close the mmap'd file,
- so that we don't leak the descriptor. I was previously under the
- mistaken impression that closing the fd unmapped the memory, which is
- not the case. Thanks to Cedric Cellier for the tip!
-
-** Fix bugs related to mutation, the null string, and shared substrings
-
- * libguile/strings.c (scm_i_is_narrow_string, scm_i_try_narrow_string,
- scm_i_string_set_x): Check to see if the provided string is a
- mutation-sharing substring, and do the right thing in that case.
- Previously, if such a string was passed to these functions, they would
- behave very badly: while trying to fetch and/or mutate the cell
- containing the stringbuf, they were actually fetching or mutating the
- cell containing the original shared string. That's because
- mutation-sharing substrings store the original string in CELL_1,
- whereas all other strings store the stringbuf there.
-
-** deprecate SCM_ASRTGO
-
-** allow scm_display_error to use a stack as the first argument
-
- * libguile/backtrace.c (scm_display_error): Allow a deprecated use of
- this function to pass a stack as the first argument. Thanks to Peter
- Brett for pointing it out, in
- http://lists.gnu.org/archive/html/guile-user/2011-06/msg00000.html.
-
-** i18n: Fix gc_malloc/free mismatch on non-GNU systems.
-
- * libguile/i18n.c (scm_i_locale_free): Remove.
- (smob_locale_free): Define only when USE_GNU_LOCALE_API.
- (scm_make_locale)[!USE_GNU_LOCALE_API]: Allocate
- `c_locale->locale_name' with `scm_gc_strdup', not `malloc'.
-
-** Make sure `regexp-quote' tests use Unicode-capable string ports.
-
- * test-suite/tests/regexp.test (with-unicode): New macro.
- ("regexp-quote"): Wrap all `regexp-quote' calls in it. This fixes
- tests on machines where the default port encoding is US-ASCII.
-
-** Have `cpu-word-size' error out on unknown CPUs; add support for MIPSEL.
-
-** permit non-date values for Expires header
-
- * module/web/http.scm ("Expires"): Permit (some) non-date values.
-
-** Remove null string optimization from scm_from_stringn
-
- * libguile/strings.c (scm_from_stringn): Always return a freshly
- allocated string from scm_from_stringn, even when asked to construct
- the null string, in accordance with the R5RS. Previously, we
- optimized the null string case by returning a reference to a global
- null string object (scm_nullstr).
-
-** Empty substrings no longer reference the original stringbuf
-
- * libguile/strings.c (scm_i_substring, scm_i_substring_read_only,
- scm_i_substring_shared): When asked to create an empty substring,
- return a freshly allocated null string. Previously, an empty
- substring needlessly held a reference to the original stringbuf.
-
-** scm_i_substring_copy tries to narrow the substring
-
- * libguile/strings.c (scm_i_substring_copy): Try to narrow the substring
- if it came from a wide string.
-
-** Avoid calling `u32_conv_from_encoding' on the null string
-
- * libguile/strings.c (scm_from_stringn): Avoid calling
- `u32_conv_from_encoding' on the null string, by using the same
- fast-path code used if (encoding == NULL). This is an optimization,
- and also avoids any possible encoding errors.
+** Don't leak file descriptors when mmaping objcode.
+** Fix bugs related to mutation, the null string, and shared substrings.
+** Deprecate SCM_ASRTGO.
+** Add deprecated shim for `scm_display_error' with stack as first argument.
+** i18n: Fix gc_malloc/free mismatch on non-GNU systems.
+** Make sure `regexp-quote' tests use Unicode-capable string ports.
+** Have `cpu-word-size' error out on unknown CPUs; add support for MIPSEL.
+** `scm_from_stringn' always returns unique strings.
+** Empty substrings no longer reference the original stringbuf.
+** `scm_i_substring_copy' tries to narrow the substring.
+** Avoid calling `u32_conv_from_encoding' on the null string.
