*** Add SRFI-25 implementation
|
** The #!r6rs directive now influences read syntax
|
||||||
|
|
||||||
Adds an implementation of SRFI 25 on top of Guile's native arrays. The
|
|
||||||
implementation does not introduce a disjoint type; Guile arrays and
|
|
||||||
SRFI-25 arrays can be used interchangably, though with different, partly
|
|
||||||
conflicting APIs.

*** SRFI-14 character data set
|
** 'read' now accepts "\(" as equivalent to "("
|
||||||
|
|
||||||
SRFI-14 character data set has been regenerated for Unicode 8.0.0.
|
This is indented for use at the beginning of lines in multi-line strings
|
||||||
|
to avoid confusing Emacs' lisp modes. Previously "\(" was an error.
|
||||||
|
|
||||||
*** Web modules
|
** SRFI-14 character data set upgraded to Unicode 8.0.0
|
||||||
|
|
||||||
The (web server) module now exports 'server-impl' procedures, (web server
|
** SRFI-19 table of leap seconds updated
|
||||||
http) exports the 'http' server implementation.
|
|
||||||
|
|
||||||
Also, http location header accepts URI-reference, not just absoluteURIs.
|
** 'string-hash', 'read-string', and 'write' have been optimized
|
||||||
|
|
||||||
*** Strings
|
* New interfaces
|
||||||
|
|
||||||
The following 2 new procedures have been added: 'string-utf8-length' and
|
** New SRFI-28 string formatting implementation
|
||||||
'scm_c_string_utf8_length'.
|
|
||||||
|
|
||||||
'string-hash' has been optimized: this yields a 50% improvement on the
|
** New (ice-9 unicode) module
|
||||||
"narrow string" benchmark of 'hash.bm', 41% on "wide string", and 76% on
|
|
||||||
"long string".
|
|
||||||
|
|
||||||
'write' has been optimized: this shows a 19% improvement on the "string
|
See "Characters" in the manual.
|
||||||
without escapes" micro-benchmark of 'write.bm', and 12% on "string with
|
|
||||||
escapes".
|
|
||||||
|
|
||||||
'read-string' speed up: this yields a 20% improvement on the
|
** Web server
|
||||||
"read-string" benchmark.
|
|
||||||
|
|
||||||
'scm_string_hash' has been deprecated.
|
The (web server) module now exports 'make-server-impl', 'server-impl?',
|
||||||
|
and related procedures. Likewise, (web server http) exports 'http'.
|
||||||
|
|
||||||
'scm_read_string_like_syntax' now accept "\(" as equivalent to "(".
|
** New procedures: 'string-utf8-length' and 'scm_c_string_utf8_length'
|
||||||
|
|
||||||
*** Libguile
|
** New 'EXIT_SUCCESS' and 'EXIT_FAILURE' Scheme variables
|
||||||
|
|
||||||
Tow new macros have been added: 'SCM_VALIDATE_SIZE_COPY' and
|
** New C macro 'SCM_VALIDATE_SIZE_COPY'
|
||||||
SCM_NUM2SIZE.
|
|
||||||
|
|
||||||
*** New Module
|
** New C functions to disable automatic SMOB finalization
|
||||||
|
|
||||||
Add (ice-9 unicode) module.
|
The new 'scm_set_automatic_finalization_enabled' C function allows you
|
||||||
|
to choose whether automatic object finalization should be enabled (as
|
||||||
|
was the case until now, and still is by default.) This is meant for
|
||||||
|
applications that are not thread-safe nor async-safe; such applications
|
||||||
|
can disable automatic finalization and call the new 'scm_run_finalizers'
|
||||||
|
function when appropriate.
|
||||||
|
|
||||||
*** SMOBs
|
See the "Garbage Collecting Smobs" and "Smobs" sections in the manual.
|
||||||
|
|
||||||
Functionalities have been added to disable automatic finalization: see
|
** Cross-compilation to ARM
|
||||||
the (Smobs) documentation node for the details and new functions.
|
|
||||||
|
|
||||||
*** Posix
|
More ARM cross-compilation targets are supported: "arm.*eb",
|
||||||
|
"^aarch64.*be", and "aarch64".
|
||||||
|
|
||||||
'EXIT_SUCCESS' and 'EXIT_FAILURE' added and documented.
|
* New deprecation
|
||||||
|
|
||||||
*** Architectures
|
** The undocumented and unused C function 'scm_string_hash' is now deprecated
|
||||||
|
|
||||||
The following ARM target have been added: "arm.*eb", "^aarch64.*be", and
|
* Bugs fixed
|
||||||
"aarch64".
|
|
||||||
|
|
||||||
