Syntax Coloring for Helma Skins

This is my first attempt to create a TextMate language grammar providing syntax coloring for Helma *.skin files.

Known issues

• Multi-line macros are not properly rendered
• Positional macro parameters have wrong color (should be string)

Unfortunately, TM grammar documentation is scarce; I mainly used the following resources to achieve the goal:

• Notes on how to create a Language Grammar and Custom Theme for a Textmate Bundle
• VS Code’s html.json and php.tmLanguage.json files
• Introduction to Scopes
• Scope Selector Reference
