1 Version 0.8.0 2 - Added tre_ prefix to all functions exported from libtre. This 3 changes the binary interface (ABI). The old source interface 4 (API) is still available in <tre/regex.h>. New programs should 5 use <tre/tre.h>. 6 7 - Visual C++ 6 project files replaced with Visual Studio 2008 files. 8 9 - Bug fixes. 10 11 Version 0.7.6 12 - The license is changed from LGPL to a BSD-style license. The new 13 license is essentially the same as the "2 clause" BSD-style 14 license used in NetBSD. See the file LICENSE for details. 15 16 - No longer using gnulib due to potential license conflicts. 17 18 - Bug fixes. 19 20 Version 0.7.5 21 - Swedish translation added. 22 23 - Makefile and source code distribution problems fixed. 24 25 - Documentation updates. 26 27 - Adding a "+" or "*" after another repetition operator is now an 28 error instead of an application of that operator and gives the 29 REG_BADRPT error. Adding a "?" means matching as few characters 30 as possible and is still allowed. 31 32 This change was made to avoid confusion with "possessive" 33 (non-backtracking) quantifiers. In Java (and .NET?) adding a "+" 34 means that the matcher doesn't backtrack over that point. In 35 previous versions of TRE adding a "+" or "*" caused the 36 backtracking matcher to backtrack a lot more instead of less. In 37 some cases this caused very slow execution. 38 39 - New agrep command line option -q (--quiet, --silent). 40 41 - Bug fixes: 42 - agrep now correctly returns exit code 1 when no matches found. 43 - Fixed regexp parser bug affecting big-endian 64 bit 44 architectures (sparc, ppc). The bug caused all regexps to match 45 an empty string and nothing else. 46 - Fixed agrep memory usage problems when reading from pipes. 47 48 Version 0.7.4 49 50 - TRE now builds cleanly on x86_64 and other 64 bit platforms. 51 There was a large number of (basically harmless) compiler warnings 52 in previous versions. 53 54 - Now builds and works on Cygwin and MinGW. Libtool was updated to 55 a version which works on these platforms, and the Makefiles and 56 configure scripts were adjusted so that DLLs are now built on 57 these platforms. 58 59 - agrep now handles long command line options on all platforms. 60 61 - Bug report email address is now tre-general (a] lists.laurikari.net. 62 63 - Many bug fixes, including: 64 - The RPM spec file now works with recent rpmbuild versions 65 - agrep no longer includes record delimiters in records, so for 66 example "echo foo | agrep 'foo$'" works as expected. 67 - agrep help texts and man page updated. 68 69 Version 0.7.3 70 - The license has been changed from GPL to LGPL. 71 72 - New command line option to agrep: --show-position 73 74 - New REG_UNGREEDY cflags and 'U' pattern modifier. 75 76 - Bug fixes. 77 78 Version 0.7.2 79 - Bug fixes. 80 81 Version 0.7.1 82 - New command line options to agrep: --delimiter-after, --color 83 84 - Man page for agrep added. 85 86 - Some bugs fixed. 87 88 Version 0.7.0 89 - reguexec() added. 90 91 - tre_have_backrefs() and tre_have_approx() added. 92 93 - New syntax: \Q, \E, \x1B, \x{263a}, (?inr-inr), (?inr-inr:regex). 94 95 - New compilation flag REG_RIGHT_ASSOC. 96 97 - New execution flags REG_APPROX_MATCHER and REG_BACKTRACKING_MATCHER. 98 99 - Included Python language bindings contributed by Nikolai SAOUKH. 100 101 - Several bugs and compilation problems fixed. 102 103 Version 0.6.8 104 - Fixed to use iswctype() if found instead of always using 105 iswalpha() and friends. Now [[:blank:]] should work again on 106 systems where iswctype() is available. 107 108 Version 0.6.7 109 - Fixed the -h (--no-filename) option of agrep to work again. 110 111 - Added the -y option to agrep. It does nothing, and exists only 112 for compatibility with the non-free version of agrep. 113 114 - Fixed bugs: handling null bytes in multibyte mode, exponential 115 memory usage problem when using lots of macros (e.g. \s or \d) in 116 a regexp, and bugs in expanding {m,n} repeats (still!). 117 118 - wctype() and iswctype() are no longer required for wchar support, 119 iswalpha() and friends will be used instead if wctype() and 120 iswctype() are not found. 121 122 - Added support for compiling against libutf8. 123 124 - Added the tre_config() function to get information about the 125 optional features compiled in the TRE library. Also added 126 tre_version(). 127 128 - Some documentation updates. 129 130 Version 0.6.6 131 - Fixed bugs which occurred sometimes when "{m,n}" repeats were used 132 in conjunction with "*", "+", or "?". 133 134 - Added the -H (--with-filename) option to agrep. 135 136 Version 0.6.5 137 - Fixed bug which occurred whine several "{m,n}" repeats were used 138 in one regex. 139 140 - Fixed several bugs related to REG_NOSUB or NULL pmatch[] arrays 141 being used for regexec(). 142 143 - C++ or Fortran compilers no longer checked by the configure 144 script. 145 146 - Some documentation additions. 147 148 Version 0.6.4 149 - Fixed bug in handling iterations (like "+" and "*") inside "{m,n}" 150 repeats. This should get rid of performance problems and 151 incorrect results with certain regexps involving "{m,n}" repeats. 152 153 Version 0.6.3 154 - Fixed back references when REG_NOSUB is used. 155 156 - Compilation errors and warnings fixed. Now this should compile on 157 systems that don't have wide character support, like OpenBSD, and 158 works on 64 bit machines. 159 160 Version 0.6.2 161 - Bug fixes. 162 163 Version 0.6.1 164 - Bug fixes. 165 166 - Some documentation updates. 167 168 Version 0.6.0 169 - The doc/ directory is now actually included in source 170 distributions (oops). 171 172 - Bug fixes. 173 174 - alloca() is no longer a requirement. The configure script still 175 looks for it, and it is used if found. 176 177 - New approximate matching syntax. The new syntax allows 178 approximate matching to be done even using the standard regex API 179 (match costs are only available when the regaexec() API is used). 180 181 - REG_LITERAL implemented. 182 183 Version 0.5.3 184 - Bug fixes and compilation fixes. 185 186 - Best match mode (-B) for agrep. 187 188 Version 0.5.2 189 - System ABI support. TRE is now by default configured to be 190 compatible with the system regex binary interface (by including 191 the system regex.h and using the definitions there instead of 192 TRE's own). This can be disabled with --disable-system-abi. 193 194 - Added a pkg-config file `tre.pc'. 195 196 - Added support for minimal (non-greedy) repetition operators 197 "*?", "+?", "??", and "{m,n}?". They work similarly to the ones 198 in Perl, except the number of characters matched is minimized 199 instead of the number of repetitions. 200 201 - Added some documentation in the doc/ subdirectory. 202 203 - Bug fixes. 204 205 Version 0.5.1 206 - Bug fixes. 207 208 Version 0.5.0 209 - Approximate matching functions now fill the pmatch[] array of 210 submatches if wanted. 211 212 - Support for back referencing (not for approximate matching). 213 214 - Changed approximate matching API to be more easily extendible in 215 the future. The match cost is now returned. 216 217 - Bug fixes. 218 219 - Windows project files (original versions contributed by Aymeric 220 Moizard <jack (a] atosc.org>, thanks!). 221 222 Version 0.4.1 223 - Fixed installed headers. 224 225 - Fixed compilation problems. 226 227 Version 0.4.0 228 - The name of the package changed to TRE. 229 230 - New API for approximate regexp matching. 231 232 - New command line utility `agrep' for approximate regexp matching 233 in the style of grep. 234 235 - New translation for Finnish (fi) has been added. 236 237 - Optimizations in regexec. 238 239 - Wide character support and multibyte character set support can be 240 turned off with --disable-wchar and --disable-multibyte, 241 respectively. 242 243 - Lots of bugfixes. 244
