Compiling CoffeeScript with You

I am actually trying to recompile the CoffeeScript compiler made in CoffeeScript from the github repository, but I am unable to recompile a single coffee source file.

I tried to install the compiler coffee

with npm

, but it gives me a command coffee

that does it when I try to run:

coffee src/lexer.coffee

Or:

coffee -c src/lexer.coffee

Error: in lexer.coffee, Parse error on line 115: Unexpected "..."
    in Object.parseError (/ usr / lib / coffee-script / lib / coffee-script / parser.js: 477: 11)
on .. .
[Long stacktrace here]

So how can I try to run directly the compiler present in the github repository? When I try to run the scripts of the executables bin/coffee

or bin/cake

even in root mode or using nodeJS they print nothing and return 1.

AND

When I try to run scripts on executable files bin/coffee

or bin/cake

even in root mode or with node JS, they print nothing and return 1.

and



coffee -v

and node -v

both print nothing and still return 1. Same thing when I go to the cloned coffeescript repository and try to run./bin/coffee -v

Indicate that nodejs is not installed correctly. (Or at least not set as coffeescript expects). On some Linux installations, another application might be installed like node

, and this might conflict with scripts that expect node

nodejs to be. See related question: nodejs vs node on ubuntu 12.04

Are you missing cake ? If you look at the source, CoffeeScript is used cake

as a build tool.

If I am missing something, the instructions in the README are not accurate with regards to creating the project.

I managed to build the compiler by following these steps:



  • Clone the CoffeeScript report.
  • Run the npm install

    CoffeeScript replica from the root to install the required dependencies.
  • Install cake: npm install cake

    (I personally hate disliking global installs, so I always just set deps local to the project.)
  • Assemble the cake: ./node_modules/.bin/cake build

  • If there is no error, make sure the tests passed: ./node_modules/.bin/cake test

  • Profit!

I'm opening the PR right now to update these instructions in the README.

EDIT: A PR was opened for this: https://github.com/jashkenas/coffeescript/pull/4031
