| tre-config.h contains additional defines that their configure puts in | |
| config.h. | |
| We have remapped the POSIX entry points with a tre_ suffix: without | |
| it there was confusion with entry points in OS libraries on some OSes | |
| (e.g. macOS). | |
| alloca has been disabled: the declarations used do not work on | |
| Windows, and most likely not on FreeBSD. | |
| The way we compile it, TRE works internally in one of three modes | |
| STR_BYTE, using bytes | |
| STR_MBS , using wchar_t for matching, I/O in MBCS | |
| STR_WIDE, using wchar_t | |
| We've added interfaces tre_regcompb, tre_regncompb, tre_regexecb, | |
| tre_regnexecb and regaexecb to force STR_BYTE. Unless forced, bytes | |
| are used in a single-byte locale and wchar_t in a MBCS. We need to | |
| force for useBytes=TRUE, for support for UTF-8 encoded strings | |
| in a single-byte locale (principally on Windows) and when dealing with | |
| raw vectors. You do need to ensure that regcomp and regexec use the | |
| same type. | |
| The offsets in the regmatch_t structure are in characters for | |
| STR_WIDE, bytes for the other two modes. | |
| On Windows (MinGW?), iswctype is missing 'blank'. | |
| REG_LITERAL was not matching "" in some cases, hence a change at | |
| line 1652 of tre-parse.c. | |
| We fixed stack trampling in tre_tnfa_run_approx() and converted | |
| tre_ast_to_tnfa() from recursion to iteration over a TRE stack. | |
| We commented out in tre-match-approx.c | |
| /* These seem compiler/OS-specific, but unexplained | |
| On Linux the first is intended to be used only with GCC. | |
| #define __USE_STRING_INLINES | |
| #undef __NO_INLINE__ | |
| */ | |
