* Notable changes
|
||||
|
||||
** guile.m4 allows selection of guile 2.0, 1.8, etc.
|
||||
** New guile.m4
|
||||
|
||||
Also GUILE_PKG; see "Autoconf Macros" in manual
|
||||
The `guile.m4' autoconf macros have been rewritten to use `guild' and
|
||||
`pkg-config' instead of the deprecated `guile-config' (which itself
|
||||
calls pkg-config).
|
||||
|
||||
** more efficient scm_gcd of inums
|
||||
There is also a new macro, `GUILE_PKG', which allows packages to select
|
||||
the version of Guile that they want to compile against. See "Autoconf
|
||||
Macros" in the manual, for more information.
|
||||
|
||||
Optimize and simplify fractions code.
|
||||
|
||||
Simplify and improve scm_i_big2dbl
|
||||
|
||||
Optimize logarithms
|
||||
** Better Windows support
|
||||
|
||||
Reimplement 'inexact->exact' to avoid mpq functions.
|
||||
Guile now correctly identifies absolute paths on Windows (MinGW), and
|
||||
creates files on that platform according to its path conventions. See
|
||||
XXX in the manual, for all details.
|
||||
|
||||
** mingw
|
||||
In addition, the new Gnulib imports provide `select' and `poll' on
|
||||
Windows builds.
|
||||
|
||||
many, many bugs.
|
||||
As an incompatible change, systems that are missing <sys/select.h> were
|
||||
previously provided a public `scm_std_select' C function that defined a
|
||||
version of `select', but unhappily it also provided its own incompatible
|
||||
definitions for FD_SET, FD_ZERO, and other system interface. Guile
|
||||
should not be setting these macros in public API, so this interface was
|
||||
removed on those plaforms (basically only MinGW).
|
||||
|
||||
remove special ifdefs, given gnulib
|
||||
** Gnulib update
|
||||
|
||||
windows file names handled correctly
|
||||
Guile's copy of Gnulib was updated to XXX. The following modules were
|
||||
imported from Gnulib: select, times, pipe-posix, fstat, getlogin, and
|
||||
poll.
|
||||
|
||||
don't provide scm_std_select on mingw and similar platforms
|
||||
|
||||
If we do not have sys/select.h, don't provide scm_std_select,
|
||||
SELECT_TYPE, FD_SET, FD_ZERO, FD_ISSET, or FD_CLR. Guile should not be
|
||||
setting these macros in public API. This is an incompatible change on
|
||||
mingw, but oh well.
|
||||
** Optimizations
|
||||
|
||||
** gnulib imports
|
||||
There were a number of improvements to the partial evaluator, allowing
|
||||
complete reduction of forms like:
|
||||
|
||||
select, times, pipe-posix, fstat, getlogin, poll
|
||||
((let ((_ 10)) (lambda () _)))
|
||||
|
||||
** optimize access to arrays of rank 1 or 2
|
||||
((lambda _ _))
|
||||
|
||||
** peval improvements
|
||||
(apply (lambda _) 1 2 3 4)
|
||||
|
||||
inlining of ((let ((_ 10)) (lambda () _)))
|
||||
(call-with-values (lambda () (values 1 2)) (lambda _ _))
|
||||
|
||||
inlining of ((lambda _ _))
|
||||
A number (ahem) of numeric operations on have been made faster, among
|
||||
them GCD and logarithms.
|
||||
|
||||
inlining of (apply (lambda _) 1 2 3 4)
|
||||
Finally, `array-ref' and `array-set!' on arrays of rank 1 or 2 is now
|
||||
faster, because it avoids building a rest list.
|
||||
|
||||
inlining of (call-with-values (lambda () (values 1 2)) (lambda _ _))
|
||||
** `include' relative file names relative to including file
|
||||
|
||||
** `include' relative paths relative to including file
|
||||
Given a relative file name, `include' will look for it relative to the
|
||||
directory of the including file. This harmonizes the behavior of
|
||||
`include' with that of `load'.
|
||||
|
||||
Local Inclusion
|
||||
** SLIB compatibility restored
|
||||
|
||||
** slib compatibility
|
||||
Guile 2.0.8 is now compatible with SLIB. You will have to use a
|
||||
development version of SLIB, however, until a new version of SLIB is
|
||||
released.
|
||||
|
||||
** warn on multithreaded fork
|
||||
** Better ,trace REPL command
|
||||
|
||||
** trace: limit length of "| | | "... prefix
|
||||
|
||||
see docs for ",trace"
|
||||
Sometimes the ,trace output for nested function calls could overflow the
|
||||
terminal width, which wasn't useful. Now there is a limit to the amount
|
||||
of space the prefix will take. See the documentation for ",trace" for
|
||||
more information.
|
||||
|
||||
** Update predefined character sets to Unicode 6.2
|
||||
|
||||
* Manual updates
|
||||
|
||||
** excise use of "iff" in the manual
|
||||
** Better SXML documentation
|
||||
|
||||
** Improve keyword notation of Texinfo function definitions.
|
||||
The documentation for SXML modules was much improved, though there is
|
||||
still far to go. See "SXML" in manual.
|
||||
|
||||
** arrays
|
||||
** Style updates
|
||||
|
||||
Document scm_array_type(), scm_array_ref(), array-length,
|
||||
scm_array_length(), scm_c_array_length().
|
||||
Use of "iff" was replaced with standard English. Keyword arguments are
|
||||
now documented consistently, along with their default values.
|
||||
|
||||
Fix wording of documentation for array-in-bounds?
|
||||
** An end to the generated-documentation experiment
|
||||
|
||||
** better sxml docs
|
||||
When Guile 2.0 imported some modules from Guile-Lib, they came with a
|
||||
system that generated documentation from docstrings and module
|
||||
commentaries. This produced terrible documentation. We finally bit the
|
||||
bullet and incorporated these modules into the main text, and will be
|
||||
improving them manually over time, as is the case with SXML. Help is
|
||||
appreciated.
|
||||
|
||||
"SXML" in manual
|
||||
** New documentation
|
||||
|
||||
** updates
|
||||
|
||||
scm_new_smob instead of SCM_NEWSMOB / SCM_RETURN_NEWSMOB.
|
||||
procedural interface to vectors (scm_c_vector_ref et al).
|
||||
|
||||
replace old foreign->bytevector and bytevector->foreign with the new
|
||||
procedure names using pointer.
|
||||
|
||||
** an end to the generated-documentation experiment
|
||||
|
||||
** document program-arguments-alist and program-lambda-list
|
||||
|
||||
** update GOOPS class hierarchy diagram in web and pdf
|
||||
There is now documentation for `scm_array_type', and `scm_array_ref', as
|
||||
well as for the new `array-length' / 'scm_c_array_length' /
|
||||
`scm_array_length' functions. `array-in-bounds?' has better
|
||||
documentation as well. The `program-arguments-alist' and
|
||||
`program-lambda-list' functions are now documented. Finally, the GOOPS
|
||||
class hierarchy diagram has been regenerated for the web and print
|
||||
output formats.
|
||||
|
||||
* New deprecations
|
||||
|
||||
** (ice-9 mapping)
|
||||
|
||||
** Deprecate generalized vector interface
|
||||
|
||||
scm_generalized_vector_p, scm_generalized_vector_length,
|
||||
scm_generalized_vector_ref, scm_generalized_vector_set_x,
|
||||
scm_generalized_vector_to_list
|
||||
The generalized vector interface, introduced in 1.8.0, is simply a
|
||||
redundant, verbose interface to arrays of rank 1. `array-ref' and
|
||||
similar functions are entirely sufficient. Thus,
|
||||
`scm_generalized_vector_p', `scm_generalized_vector_length',
|
||||
`scm_generalized_vector_ref', `scm_generalized_vector_set_x', and
|
||||
`scm_generalized_vector_to_list' are now deprecated.
|
||||
|
||||
** deprecate SCM_CHAR_CODE_LIMIT and char-code-limit
|
||||
** Deprecate SCM_CHAR_CODE_LIMIT and char-code-limit
|
||||
|
||||
** deprecate http-get*
|
||||
These constants were defined to 256, which is not the highest codepoint
|
||||
supported by Guile. Given that they were useless and incorrect, they
|
||||
have been deprecated.
|
||||
|
||||
The #:streaming? argument subsumes the functionality of http-get*. Also
|
||||
deprecate #:extra-headers argument in favor of #:headers.
|
||||
** Deprecate `http-get*'
|
||||
|
||||
The new `#:streaming?' argument to `http-get' subsumes the functionality
|
||||
of `http-get*'. Also, the `#:extra-headers' argument is deprecated in
|
||||
favor of `#:headers'.
|
||||
|
||||
** Deprecate (ice-9 mapping)
|
||||
|
||||
This module, present in Guile since 1996 but never used or documented,
|
||||
has never worked in Guile 2.0. It has now been deprecated and will be
|
||||
removed in Guile 2.2.
