CirruScript: a JavaScript generator in Cirru Grammar
Live Docs: http://script.cirru.org/
Play with CirruScript by typing in here: http://repo.cirru.org/script/
The AST transformer of CirruScript is Scirpus https://github.com/Cirru/scirpus .
Usage
Here is a demo of calling compiler:
yarn add cirru-scriptscript = require 'cirru-script'
code = "console.log :demo"
script.compile codeCommand-line tool
By installing CirruScript at global, you'll get command cirruscript(and crs for short):
npm i -g cirru-script
cirruscript
# enter REPL
cirruscript>
cirruscript a.cirru
# evaluates a file
File compiling and SourceMaps support might come in the future.
Add DISPLAY_JS for displaying compiled js:
DISPLAY_JS=true cirruscript a.cirrucompile sub-command can compile code:
cirruscript compile from-dir to-dirSyntax
