GNU Source-Highlight 3.1.1

In this new version of GNU Source-Highlight some additions were made to the API of the library; the most important are:

  • access to static global LangDefManager, LangMaps is provided through the new class Instances so that there's no need to create continuously instances of these classes;
  • the library also provides now utility functions for accessing .lang and .outlang files;
  • functions are provided for setting the data dir option globally, in order to increase consistency in applications that use the library (changing such value globally makes sure that the change will be visible in all parts of the library).
Moreover, two new language definition files were added: Texinfo and Haskell (thanks to Sergey Astanin); here are two examples:


(@ref{Generating References}).
\input texinfo @c -*-texinfo-*-
@c This file uses the @command command introduced in Texinfo 4.0.
@c %**start of header

@include version.texi

@c @setchapternewpage odd
