Development Hints

This extension was initially created using VS Code's Yeoman templates, running yo code and selecting the New Language option.

The Textmate "grammar" was developed using the syntax highlighting grammer edior Iro and the .plist/.json transformation tool http://json2plist.sinaapp.com/.

For working on the TextMate "grammar" please consider using the Iro specifcaton file ../Xtext.iro.

The language server is created using the Xtext language creation framework itself. The Xtext grammar for that was taken from the eclipse/xtext-core project. Only the grammar name was adapted to avoid bootstrapping compilation problems.

Anyone to take over pushing this extension forward making it more valuable is wellcome. I'm not planing to invest a lot more time, unfortunately.
