#ifndef PCRS_H_INCLUDED #define PCRS_H_INCLUDED /********************************************************************* * * File : $Source: /cvsroot/ijbswa/current/pcrs.h,v $ * * Purpose : This is the pre-pre-alpha realease of libpcrs. It is only * published at this (ugly) stage of development, because it is * needed for a new feature in JunkBuster. * * Apart from the code being quite a mess, no inconsistencies, * memory leaks or functional bugs **should** be present. * * While you ROTFL at the code, you could just as well mail me * (oes@paradis.rhein.de) with advice for improvement. * * pcrs is a supplement to the brilliant pcre library by Philip * Hazel (ph10@cam.ac.uk) and adds Perl-style substitution. That * is, it mimics Perl's 's' operator. * * Currently, there's no documentation besides comments and the * source itself ;-) * * Copyright : Written and copyright 2001 by Sourceforge IJBSWA team. * * Revisions : * $Log: pcrs.h,v $ * Revision 1.5 2001/07/18 17:27:00 oes * Changed interface; Cosmetics * * Revision 1.4 2001/06/29 13:33:19 oes * - Cleaned up, commented and adapted to reflect the * changes in pcrs.c * - Introduced the PCRS_* flags * * Revision 1.3 2001/06/09 10:58:57 jongfoster * Removing a single unused #define which referenced BUFSIZ * * Revision 1.2 2001/05/25 11:03:55 oes * Added sanity check for NULL jobs to pcrs_exec_substitution * * Revision 1.1.1.1 2001/05/15 13:59:02 oes * Initial import of version 2.9.3 source tree * * Revision 1.4 2001/05/11 01:57:02 rodney * Added new file header standard w/RCS control tags. * * revision 1.3 2001/05/08 02:38:13 rodney * Changed C++ "//" style comment to C style comments. * * revision 1.2 2001/04/30 02:39:24 rodney * Made this pcrs.h file conditionally included. * * revision 1.1 2001/04/16 21:10:38 rodney * Initial checkin * *********************************************************************/ #define PCRS_H_VERSION "$Id: pcrs.h,v 1.5 2001/07/18 17:27:00 oes Exp $" #include #ifdef __cplusplus extern "C" { #endif /* * Constants: */ #define FALSE 0 #define TRUE 1 /* Capacity */ #define PCRS_MAX_MATCHES 300 #define PCRS_MAX_SUBMATCHES 33 /* Error codes */ #define PCRS_ERR_NOMEM -10 /* Failed to acquire memory. */ #define PCRS_ERR_CMDSYNTAX -11 /* Syntax of s///-command */ #define PCRS_ERR_STUDY -12 /* pcre error while studying the pattern */ #define PCRS_ERR_BADJOB -13 /* NULL job pointer, pattern or substitute */ /* Flags */ #define PCRS_GLOBAL 1 /* Job should be applied globally, as with perl's g option */ #define PCRS_SUCCESS 2 /* Job did previously match */ #define PCRS_TRIVIAL 4 /* Backreferences in the substitute are ignored */ /* * Data types: */ /* A compiled substitute */ typedef struct PCRS_SUBSTITUTE { char *text; /* The plaintext part of the substitute, with all backreferences stripped */ int backrefs; /* The number of backreferences */ int block_offset[PCRS_MAX_SUBMATCHES]; /* Array with the offsets of all plaintext blocks in text */ int block_length[PCRS_MAX_SUBMATCHES]; /* Array with the lengths of all plaintext blocks in text */ int backref[PCRS_MAX_SUBMATCHES]; /* Array with the backref number for all plaintext block borders */ int backref_count[PCRS_MAX_SUBMATCHES]; /* Array with the number of reference to each backref index */ } pcrs_substitute; typedef struct PCRS_MATCH { /* char *buffer; */ int submatches; /* Number of submatches.
