GNU Source-Highlight 2.10

Here's the new release of GNU Source-Highlight.

From the architectural point of view, I completely re-written the engine that uses regular expression, since it is now oriented towards a library (I'll try to extract a library from source-highlight as soon as possible, in order to provide, e.g., highlighting functionalities to qt text editors without the need to implement the qt highlighter yourself).

Here's the complete list of changes:

Version 2.10

* formatting is applied even when generating anchors and references
* noref is handled also for output languages using onestyle (e.g., xhtml)
* improved fortran highlighting
* improved python highlighting
* fixed title in docbook output
* language definition for ldap files (e.g., ldiff files)
* language definition for autoconf files
* improved m4 language definition
* improved logtalk language definition
* url.lang handles ~ in urls
* language definition for glsl.lang (provided by Cesare Tirabassi)

There are some new languages that are highlighted, in the following you will see some examples:

autoconf:

dnl this is only for developers who use double dispatch
dnl doublecpp can be found at http://www.lorenzobettini.it/software/doublecpp
AC_PATH_PROGS(DOUBLECPP, doublecpp)
AM_CONDITIONAL(NO_DOUBLECPP, test -z "$ac_cv_path_DOUBLECPP" )

dnl this is for testing purpose and development
AC_PATH_PROGS(VALGRIND, valgrind)

dnl this is only for developers who use change command line options
AC_PATH_PROGS(HELP2MAN, help2man)
AM_CONDITIONAL(NO_HELP2MAN, test -z "$ac_cv_path_HELP2MAN" )

dnl this is for generating references
AC_PATH_PROGS(CTAGS, ctags exuberant-ctags)
if test -n "$ac_cv_path_CTAGS"; then
AC_CTAGS_FLAGS
AM_CONDITIONAL(NO_CTAGS, test "$ac_ctags_flags" = "no" )
else
AM_CONDITIONAL(NO_CTAGS, test -z "$ac_cv_path_CTAGS" )
fi
