This directory contains files that provide:

• Support for syntax highlighting and other text editing services for text editors and IDEs.
• Support for syntax highlighters (used in e.g in wikis, code repositories, source code browsers, bug trackers, and shells).
• Support for setting Logtalk projects using common version control systems (e.g. git).
• Sample source files for testing syntax highlighting support. The Logtalk syntax coloring support is also usable for Prolog coding.

  The files in this directory can be regarded as contributions to third-party text editors and syntax highlighters. Thus, as a general rule, these files are dual-licensed under the Logtalk license and the license used by the third-party software.

  Some text editors already include support for Logtalk. If that is the case of your favorite editor, you may want to check if the supporting files provided in this directory are newer than the editor ones.

  Logtalk source files (including the library entities and the programming examples) are indented using tabs and are expected to remain perfectly indented no matter your tab width preference (a common setting is a tab width equivalent to 4 spaces).

  You may notice that support for some text editors, notably for Windows-only editors, is relatively poor. Depending on the text editor, proper syntax highlighting support for Prolog and Logtalk may require support for regular expressions with zero-width look-ahead and look-behind assertions, which some editors lack.

  Some text editors supporting regular expressions contain bugs and/or hard-coded limitations that prevent full optimization of the syntax coloring patterns.

Online code formatters

http://hilite.me is an online service that converts code snippets into pretty-printed HTML format. It supports many programming languages, including Logtalk and Prolog.
