1 | wxWindows regex |
| 2 | ---------------- | |
| 3 | This is a version of Henry Spencer's regex, | |
| 4 | which was taken from postresql, which was | |
| 5 | taken from the source of TCL (Toolkit Command Language). | |
| 6 | ||
| 7 | This is version of Henry Spencer's library is | |
| 8 | modified by the wxWindows team. The modifications | |
| 9 | made by the wxWindows team are as follows: | |
| 161c73a3 | 10 | regcustom.h (all source code) |
| e970653a RN |
11 | regex.h (function wrappers, other) |
| 12 | regc_locale.c (A function or two). | |
| 13 | All the rest (Using standard c library routines instead of | |
| 14 | postresql routines, various cleanup/optimizations) | |
| 15 | ||
| 161c73a3 RN |
16 | The source code that is wxWindows-specific is as follows: |
| 17 | regcustom.h (all source code, see comments in source on how to replace) | |
| 18 | regex.h (where noted with comments in source, compiler workarounds) | |
| e970653a RN |
19 | regcomp.c (a few of the functions prefixed with wx_, |
| 20 | these may be replaced by c library routines) | |
| 21 | ||
| 22 | This newer library was chosen over the old one because | |
| 23 | Henry Spencer's old library did not support unicode and | |
| 24 | had some other bugs that were fixed by this one, and | |
| 25 | the license was incompatible with the wxWindows license | |
| 26 | and the gpl. | |
| 27 | ||
| 161c73a3 RN |
28 | Regular Expression syntax documentation is in re_syntax.n. |
| 29 | Programming information (from older regex, but with | |
| 30 | the function wrappers implemented in the wxWindows | |
| 31 | version, the usage is somewhat the same) is in regex.3. | |
| 32 | ||
| e970653a | 33 | Modifications made by the wxWindows team are not licensed. |

| 42 | See WHATSNEW for change listing. | |
| 43 | ||
| 44 | installation notes: | |
| 45 | -------- | |
| 46 | Read the comments at the beginning of Makefile before running. | |
| 47 | ||
| 48 | Utils.h contains some things that just might have to be modified on | |
| 49 | some systems, as well as a nested include (ugh) of <assert.h>. | |
| 50 | ||
| 51 | The "fake" directory contains quick-and-dirty fakes for some header | |
| 52 | files and routines that old systems may not have. Note also that | |
| 53 | -DUSEBCOPY will make utils.h substitute bcopy() for memmove(). | |
| 54 | ||
| 55 | After that, "make r" will build regcomp.o, regexec.o, regfree.o, | |
| 56 | and regerror.o (the actual routines), bundle them together into a test | |
| 57 | program, and run regression tests on them. No output is good output. | |
| 58 | ||
| 59 | "make lib" builds just the .o files for the actual routines (when | |
| 60 | you're happy with testing and have adjusted CFLAGS for production), | |
| 61 | and puts them together into libregex.a. You can pick up either the | |
| 62 | library or *.o ("make lib" makes sure there are no other .o files left | |
| 63 | around to confuse things). | |
| 64 | ||
| 65 | Main.c, debug.c, split.c are used for regression testing but are not part | |
| 66 | of the RE routines themselves. | |
| 67 | ||
| 68 | Regex.h goes in /usr/include. All other .h files are internal only. | |
