Open Source Perl Code Formatters

Perl script to add indentation (leading horizontal space) to LaTeX files. It can modify line breaks before, during and after code blocks; it can perform text wrapping and paragraph line break removal. It can also perform string-based and regex-based substitutions/replacements. The script is customizable through its YAML interface. latexindent.exe is a standalone executable file that does not require a perl installation. A nice way to test the script is to navigate to the test-cases directory, and then run the command (on Linux/Mac -- sorry, a Windows test-case version is not available)

EPIC is an open source Perl IDE for the Eclipse platform. Features supported are syntax highlighting, on the fly syntax check, content assist, perldoc support, source formatter, templating support, regular expression plugin and a Perl debugger.
