// Compression helper for CodeMirror
|
|
//
|
|
// Example:
|
|
//
|
|
// bin/compress codemirror runmode javascript xml
|
|
//
|
|
// Will take lib/codemirror.js, addon/runmode/runmode.js,
|
|
// mode/javascript/javascript.js, and mode/xml/xml.js, run them though
|
|
// the online minifier at http://marijnhaverbeke.nl/uglifyjs, and spit
|
|
// out the result.
|
|
//
|
|
// bin/compress codemirror --local /path/to/bin/UglifyJS
|
|
//
|
|
// Will use a local minifier instead of the online default one.
|
|
//
|
|
// Script files are specified without .js ending. Prefixing them with
|
|
// their full (local) path is optional. So you may say lib/codemirror
|
|
// or mode/xml/xml to be more precise. In fact, even the .js suffix
|
|
// may be speficied, if wanted.
