* module/language/cps/intset.scm (make-intset-folder): intset-fold-right
on a transient intset would dispatch to left fold after making the
persistent set. Sadness!
* doc/ref/api-data.texi (Arrays as arrays of arrays): Clarify
ambiguities, fix examples.
* libguile/arrays.c (make-shared-array): Make error messages specific to
each error case, report relevant arguments.
(array_from_pos): Return NULL on error instead of reporting error
ourselves.
(array_from_get_o): Handle the trivial case.
(scm_array_slice, scm_array_cell_ref, scm_array_cell_set_x): Don't
build error arguments before error happens. Let array_from_get_o
handle the trivial case.
Prepare for fixes to the suffix pruning. Since last_component doesn't
document a possible null result in lib/basename-lgpl.h, and the current
code also doesn't appear capable of producing one, drop the check.
libguile/filesys.c (basename): drop check for last_component null result.
Rewrite the srfi-1 C functions in Scheme and remove srfi-1.c as
planned (see the comments at the top of srfi-1.c).
The previous C code mutated intermediate results in some cases, even for
non-! functions (e.g. set-cdr! to build the result without stack growth
or a reverse!); some of the conversions preserve that approach for now.
Simple testing via https://github.com/ecraven/r7rs-benchmarks/ didn't
reveal any substantial performance regressions.
Thanks to David Thompson for reviewing the changes and suggesting
improvements.
...now that all of the C code has been migrated to Scheme.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
remove srfi-1.c.
(DOC_X_FILES): Remove srfi-1.x.
(DOT_DOC_FILES): Remove srfi-1.doc.
(modinclude_HEADERS): Remove srfi-1.h.
* libguile/init.c (scm_i_init_guile): Don't call scm_register_srfi_1.
* libguile/srfi-1.c: Remove.
* libguile/srfi-1.h: Remove.
* module/srfi/srfi-1.scm: Don't load srfi-1 from libguile.
The Scheme implementation is an adapted version of the approach used by
delete-duplicates, which allows sharing any common tail.
* libguile/srfi-1.c (scm_srfi1_remove): delete.
* libguile/srfi-1.h (scm_srfi1_remove): delete.
* module/srfi/srfi-1.scm: add remove.
Have .version depend on the Makefile, and move our
CONFIG_STATUS_DEPENDENCIES setting to an AC_SUBST, as recommended by the
automake info pages "Rebuilding Makefiles" section, so that changes to
GUILE-VERSION will update the VERSION, etc. in the generated Makefiles.
* Makefile.am (CONFIG_STATUS_DEPENDENCIES): drop.
($(top_srcdir/.version)): depend on Makefile.
* configure: add GUILE-VERSION to CONFIG_STATUS_DEPENDENCIES via
AC_SUBST.
