About pcre:
The Perl Compatible Regular Expressions library.

Latest Version |

Details about this version:
- There's an "automatic callout" feature that inserts callouts before every item in the regex, and there's a new callout field that gives the position in the pattern - useful for debugging and tracing.
- The extra_data structure can now be used to pass in a set of character tables at exec time. This is useful if compiled regex are saved and re-used at a later time when the tables may not be at the same address. If the default internal tables are used, the pointer saved with the compiled pattern is now set to NULL, which means that you don't need to do anything special unless you are using custom tables.
- It is possible, with some restrictions on the content of the regex, to request "partial" matching. A special return code is given if all of the subject string matched part of the regex. This could be useful for testing an input field as it is being typed.
- There is now some optional support for Unicode character properties, which means that the patterns items such as \p{Lu} and \X can now be used. Only the general category properties are supported. If PCRE is compiled with this support, an additional 90K data structure is include, which increases the size of the library dramatically.
- There is support for saving compiled patterns and re-using them later.
- There is support for running regular expressions that were compiled on a different host with the opposite endianness.
