Version 0.12
|
||
|
||
* regex.c does not #define bcmp/bcopy/bzero if they already are.
|
||
|
||
* regex.h does not redefine `const' if it is already defined, even if
|
||
__STDC__ is not defined.
|
||
|
||
* RE_SYNTAX_ED added (same as POSIX BRE's).
|
||
|
||
* The following bugs have been fixed, among others:
|
||
* The pattern \w+ doesn't infinite loop.
|
||
* The pattern ".+\n" is compiled correctly.
|
||
* Expressions with more than MAX_REGNUM groups are compiled correctly.
|
||
|
||
* Patterns that end in a repetition operator (e.g., `*') match
|
||
slightly faster if no looping is actually necessary.
|
||
|
||
Version 0.11 (17 Sep 92)
|
||
|
||
* Back-references to nonexistent subexpressions, as in the r.e. `abc\1',
|
||
are always invalid. Previously, they could match the literal digit,
|
||
e.g., the stated r.e. might have matched `abc1'.
|
||
|
||
* Empty subexpressions are always valid (POSIX leaves this undefined).
|
||
|
||
* Simplified rules for ^ and $ being anchors.
|
||
|
||
* One minor speedup (rewriting the C procedure `pop_failure_point' as a
|
||
macro again).
|
||
|
||
* Bug fixes involving:
|
||
- Declarations in regex.h and non-ANSI compilers.
|
||
- Bracket expressions with characters between 0x80-0xff.
|
||
- Memory leak in re_match_2 on systems requiring `alloca (0)' to
|
||
free alloca'd storage.
|
||
|
||
* Test and documentation files moved into subdirectories.
|
||
|
||
Version 0.10 (9 Sep 92)
|
||
|
||
* `obscure_syntax' is now called `re_default_syntax'.
|
||
|
||
* `re_comp's return type is no longer `const', for compatibility with BSD.
|
||
|
||
* POSIX syntaxes now include as much functionality as possible
|
||
(consistent with the standard).
|
||
|
||
* Compilation conditionals normalized to what the rest of GNU is
|
||
migrating towards these days.
|
||
|
||
* Bug fixes involving:
|
||
- Ranges with characters between 0x80 and 0xff, e.g., [\001-\377].
|
||
- `re_compile_fastmap' and the sequence `.*\n'.
|
||
- Intervals with exact counts, e.g., a{5}.
|
||
|
||
* Changed distribution to use a standard Makefile, install the info
|
||
files, use a configure script, etc.
|
||
|
||
Version 0.9
|
||
|
||
* The longest match was not always chosen: `a*|ab' didn't match `aab'.
