Release 6.0 07-Jun-05 |

--------------------- |

|
The release number has been increased to 6.0 because of the addition of several |
| 8 |
|
major new pieces of functionality. |
| 9 |
|
|
| 10 |
|
A new function, pcre_dfa_exec(), which implements pattern matching using a DFA |
| 11 |
|
algorithm, has been added. This has a number of advantages for certain cases, |
| 12 |
|
though it does run more slowly, and lacks the ability to capture substrings. On |
| 13 |
|
the other hand, it does find all matches, not just the first, and it works |
| 14 |
|
better for partial matching. The pcrematching man page discusses the |
| 15 |
|
differences. |
| 16 |
|
|
| 17 |
|
The pcretest program has been enhanced so that it can make use of the new |
| 18 |
|
pcre_dfa_exec() matching function and the extra features it provides. |
| 19 |
|
|
| 20 |
|
The distribution now includes a C++ wrapper library. This is built |
| 21 |
|
automatically if a C++ compiler is found. The pcrecpp man page discusses this |
| 22 |
|
interface. |
| 23 |
|
|
| 24 |
|
The code itself has been re-organized into many more files, one for each |
| 25 |
|
function, so it no longer requires everything to be linked in when static |
| 26 |
|
linkage is used. As a consequence, some internal functions have had to have |
| 27 |
|
their names exposed. These functions all have names starting with _pcre_. They |
| 28 |
|
are undocumented, and are not intended for use by outside callers. |
| 29 |
|
|
| 30 |
|
The pcregrep program has been enhanced with new functionality such as |
| 31 |
|
multiline-matching and options for output more matching context. See the |
| 32 |
|
ChangeLog for a complete list of changes to the library and the utility |
| 33 |
|
programs. |
