|
|
- original version |
| 6 |
|
|
|

|
|
|

|
|
1.01 Mon Sep 8 18:09:18 EST 1997 |
| 9 |
|
|
|
| 10 |
|
|
- changed "quotemeta" to "quotemeta $_" to work |
| 11 |
|
|
around bug in Perl 5.002 and 5.003 |
| 12 |
|
|
|
| 13 |
|
|
|
| 14 |
|
|
1.10 Tue Sep 30 17:23:23 EST 1997 |
| 15 |
|
|
|
| 16 |
|
|
- reworked extract_quotelike to correct handling of some obscure cases |
| 17 |
|
|
|
| 18 |
|
|
|
| 19 |
|
|
1.21 Sat Oct 4 17:21:54 EST 1997 |
| 20 |
|
|
|
| 21 |
|
|
- synchronised with Parse::RecDescent distribution (version number |
| 22 |
|
|
will now reflect that package) |
| 23 |
|
|
|
| 24 |
|
|
1.23 Fri Oct 17 10:26:38 EST 1997 |
| 25 |
|
|
|
| 26 |
|
|
- changed behaviour in scalar and void contexts. Scalar contexts |
| 27 |
|
|
now return only the extracted string. Void contexts now remove |
| 28 |
|
|
the extracted string from the first argument (or $_). |
| 29 |
|
|
|
| 30 |
|
|
1.24 |
| 31 |
|
|
|
| 32 |
|
|
- changed behaviour in scalar contexts. Scalar contexts |
| 33 |
|
|
now return the extracted string _and_ remove it from the |
| 34 |
|
|
first argument (or $_). |
| 35 |
|
|
|
| 36 |
|
|
- changed return values on failure (all contexts return undef |
| 37 |
|
|
for invalid return fields) |
| 38 |
|
|
|
| 39 |
|
|
- fixed some lurking bugs with trailing modifier handling |
| 40 |
|
|
|
| 41 |
|
|
- added :ALL tag to simplify wholesale importing of functions |
| 42 |
|
|
|
| 43 |
|
|
- fixed serious bug with embedded division operators ("/") |
| 44 |
|
|
This now also allows the ?...? form of pattern matching! |
| 45 |
|
|
|
| 46 |
|
|
1.35 Wed Jun 24 09:53:31 1998 |
| 47 |
|
|
|
| 48 |
|
|
- fixed handling of :: quantifiers in extract_variable() |
| 49 |
|
|
|
| 50 |
|
|
- numerous trivial lexical changes to make xemacs happy |
| 51 |
|
|
|
| 52 |
|
|
|
| 53 |
|
|
1.36 Tue Jul 14 12:26:04 1998 |
| 54 |
|
|
|
| 55 |
|
|
- Reinstated POD file missing from previous distribution |
| 56 |
|
|
|
| 57 |
|
|
- Added undocumented fourth parameter to extract_codeblock |
| 58 |
|
|
so as to correctly handle (?) and (s?) modifiers in |
| 59 |
|
|
RecDescent grammars. |
| 60 |
|
|
|
| 61 |
|
|
|
| 62 |
|
|
1.40 Tue Aug 4 13:54:52 1998 |
| 63 |
|
|
|
| 64 |
|
|
- Added (optional) handling of embedded quoted text to |
| 65 |
|
|
extract_delimited (see revised entry in Balanced.pod) |
| 66 |
|
|
|
| 67 |
|
|
- Added extract_tagged which extracts text between arbitrary, |
| 68 |
|
|
optionally nested start and end tags (see new entry in |
| 69 |
|
|
Balanced.pod). |
| 70 |
|
|
|
| 71 |
|
|
- Added delimited_pat which builds a pattern which matches a |
| 72 |
|
|
string delimited by any of the delimiters specified (see new |
| 73 |
|
|
entry in Balanced.pod). |
| 74 |
|
|
|
| 75 |
|
|
- Added test.pl |
| 76 |
|
|
|
| 77 |
|
|
|
| 78 |
|
|
1.41 Mon Aug 10 14:51:50 1998 |
| 79 |
|
|
|
| 80 |
|
|
- Reinstated change to extract_codeblock from 1.36 which were |
| 81 |
|
|
mysteriously lost in 1.40 |
| 82 |
|
|
|
| 83 |
|
|
|
| 84 |
|
|
1.50 Thu Aug 27 09:20:19 1998 |
| 85 |
|
|
|
| 86 |
|
|
- Improved the structure of the regex generated by |
| 87 |
|
|
delimited_pat (and used in extract_delimited). It's |
| 88 |
|
|
considerably more complex, but also more robust and |
| 89 |
|
|
much faster in the worst case. |
| 90 |
|
|
|
| 91 |
|
|
- Altered extract_variable to accept whitespace in variables, |
| 92 |
|
|
e.g. '$ a -> {'b'} -> [2]' |
| 93 |
|
|
|
| 94 |
|
|
|
| 95 |
|
|
|
| 96 |
|
|
1.51 Sat Feb 13 10:31:55 1999 |
| 97 |
|
|
|
| 98 |
|
|
- Fixed bugs in prefix matching in extract_variable: |
| 99 |
|
|
* incorrectly used default if '' specified |
| 100 |
|
|
* now handles $#array correctly |
| 101 |
|
|
|
| 102 |
|
|
- Fixed bugs in extract_codeblock: |
| 103 |
|
|
* Now handles !~ properly |
| 104 |
|
|
* Now handles embedded comments better. |
| 105 |
|
|
* Now handles "raw" pattern matches better. |
| 106 |
|
|
|
| 107 |
|
|
- Added support for single strings or qr's as |
| 108 |
|
|
'reject' and 'ignore' args to extract_tagged() |
| 109 |
|
|
|
| 110 |
|
|
- Added gen_extract_tagged() to "precompile" |
| 111 |
|
|
a specific tag extractor for repeated use |
| 112 |
|
|
(approximately 3 times faster!) |
| 113 |
|
|
|
| 114 |
|
|
|
| 115 |
|
|
1.52 Thu Mar 4 12:43:38 1999 |
| 116 |
|
|
|
| 117 |
|
|
- Added CSV parsing example to documentation of extract_multiple. |
| 118 |
|
|
|
| 119 |
|
|
- Fixed a bug with extract_codeblock in "RecDescent" mode |
| 120 |
|
|
(it would accept "subrule(s?)" and "subrule(?)", but |
| 121 |
|
|
not "subrule(s)"). Thanks, Jan. |
| 122 |
|
|
|
| 123 |
|
|
|
| 124 |
|
|
1.66 Fri Jul 2 13:29:22 1999 |
| 125 |
|
|
|
| 126 |
|
|
- Added ability to use quotelike operators in extract_bracketed |
| 127 |
|
|
|
| 128 |
|
|
- Fixed bug under 5.003 ('foreach my $func' not understood) |
| 129 |
|
|
|
| 130 |
|
|
- Added escape specification as fourth arg to &extract_delimited |
| 131 |
|
|
|
| 132 |
|
|
- Fixed handling of &delimited_pat and &extract_delimited |
| 133 |
|
|
when delimiter is same as escape |
| 134 |
|
|
|
| 135 |
|
|
- Fixed handling of ->, =>, and >> in &extract_code |
| 136 |
|
|
when delimiters are "<>" |
| 137 |
|
|
|
| 138 |
|
|
|
| 139 |
|
|
1.76 Fri Nov 19 06:51:54 1999 |
| 140 |
|
|
|
| 141 |
|
|
- IMPORTANT: Now requires 5.005 or better. |
| 142 |
|
|
|
| 143 |
|
|
- IMPORTANT: Made extract methods sensitive to the pos() |
| 144 |
|
|
value of the text they are parsing. In other words, |
| 145 |
|
|
all extract subroutines now act like patterns of the form |
| 146 |
|
|
/\G.../gc. See documentation for details. |
| 147 |
|
|
|
| 148 |
|
|
- IMPORTANT: Changed semantics of extract_multiple, in line |
| 149 |
|
|
with the above change, and to simplify the semantics to |
| 150 |
|
|
something vaguely predictable. See documentation for details. |
| 151 |
|
|
|
| 152 |
|
|
- Added ability to use qr/../'s and raw strings as extractors |
| 153 |
|
|
in extract_multiple. See documentation. |
| 154 |
|
|
|
| 155 |
|
|
- Added fourth argument to extract_codeblock to allow |
| 156 |
|
|
outermost brackets to be separately specified. See |
| 157 |
|
|
documentation for details. |
| 158 |
|
|
|
| 159 |
|
|
- Reimplemented internals of all extraction subroutines |
| 160 |
|
|
for significant speed-ups (between 100% and 2000% |
| 161 |
|
|
improvement). |
| 162 |
|
|
|
| 163 |
|
|
- Fixed nasty bug in extract_variable and extract_codeblock |
| 164 |
|
|
(they were returning prefix as well in scalar context) |
| 165 |
|
|
|
| 166 |
|
|
- Allowed read-only strings to be used as arguments in |
| 167 |
|
|
scalar contexts. |
| 168 |
|
|
|
| 169 |
|
|
- Renamed delimited_pat to gen-delimited pat (in line with |
| 170 |
|
|
gen_extract_tagged). Old name still works, but is now deprecated. |
| 171 |
|
|
|
| 172 |
|
|
- Tweaked all extraction subs so they correctly handle |
| 173 |
|
|
zero-length prefix matches after another zero-length match. |
| 174 |
|
|
|
| 175 |
|
|
|
| 176 |
|
|
1.77 Mon Nov 22 06:08:23 1999 |
| 177 |
|
|
|
| 178 |
|
|
- Fixed major bug in extract_codeblock (would not |
| 179 |
|
|
terminate if there was trailing whitespace) |
| 180 |
|
|
|
| 181 |
|
|
- Improved /.../ pattern parsing within codeblocks |
| 182 |
|
|
|
| 183 |
|
|
|
| 184 |
|
|
1.81 Wed Sep 13 11:58:49 2000 |
| 185 |

| 186 |
|
|
- Fixed test count in extract_codeblock.t |
| 187 |
|
|
|
| 188 |
|
|

|
|

| 191 |
|
|
|
| 192 |
|
|
- Added explanatory note about prefix matching (thanks again, Tim) |
| 193 |
|
|
|

| 196 |
|
|
- Pod tweak (thanks Abigail) |
| 197 |
|
|
|
| 198 |
|
|
- Allowed right tags to be run-time evaluated, so |
| 199 |
|
|
extract_tagged($text, '/([a-z]+)', '/end$1') works |
| 200 |
|
|
as expected. |
| 201 |
|
|
|
| 202 |
|
|
- Added optional blessing of matches via extract_multiple |
| 203 |
|
|
|
| 204 |
|
|
- Fixed bug in autogeneration of closing tags in extract_tagged |
| 205 |
|
|
(Thanks, Coke) |
| 206 |
|
|
|
| 207 |
|
|
- Fixed bug in interaction between extract_multiple and |
| 208 |
|
|
gen_extract_tagged (Thanks Anthony) |
| 209 |
|
|
|
| 210 |
|
|
|
| 211 |
