Developing

If you want to further develop this extension, feel free to fork it on GitHub.

You will need the jacob Lexical Tokenizer installed:

$ npm install --save jacob

To generate the lexer, run:

$ node node_modules/.bin/jacob -t Dockerfile.jacoblex -l dockerlex.js

or just run:

$ ./build.sh

which generates the lexer and zip's up the extension for release.

Also, there is a blog on how this extension was written at reapingzombies4funandprofit.
