This directory contains the logtalk.py file that provides syntax coloring support for Pygments (version 0.9 or later):

http://pygments.org/

These support files are dual-licensed under the Apache License 2.0 and the Pygments license.

Pygments includes support for Logtalk since version 0.10 as you can check using the command:

$ pygmentize -H lexer Logtalk

If support for Logtalk is outdated, replace its definition inside one of the following files (its prefix depends on where Python is installed):

site-packages/pygments/lexers/prolog.py (recent Pygments versions)
site-packages/pygments/lexers/other.py  (older Pygments versions)

with the contents of the logtalk.py from the Logtalk distribution and compile the updated file:

$ python -m py_compile prolog.py (recent Pygments versions)
$ python -m py_compile other.py  (older Pygments versions)

Finally, rebuild the lexer mappings by typing:

$ python _mapping.py

Logtalk source files (including the library entities and the programming examples) are formatted using tabs (the recommended setting is a tab width equivalent to 4 spaces). This can be specified by using the whitespace filter option tabsize:

$ pygmentize -F whitespace:tabsize=4 -O full,style=friendly -o source.html source.lgt

When your source file uses an encoding other than ASCII or ISO-Latin-1, you will need to use the encoding option. For example:

$ pygmentize -F whitespace:tabsize=4 -O encoding=utf8 -o babel.html babel.lgt

As the Pygments syntax highlighting engine itself, the logtalk.py file is licensed under the BSD license.

You may also use the Logtalk lexer with plain Prolog files by using the -l option. For example:

$ pygmentize -l logtalk -O full,style=friendly -o source.html source.pl
