coffee-inline-map

Compile CoffeeScript files with inline source maps.

Features

• Error reporting similar to the original CoffeeScript compiler.
• .litcoffee support.

Example

$ cat a.coffee
include([a.coffee])
$ coffee-inline-map a.coffee | fold -w72
syscmd([../../../bin/coffee-inline-map a.coffee | fold -w72])

$ coffee-inline-map -h
syscmd([../../../bin/coffee-inline-map -h])

Installation

# npm install -g coffee-inline-map

Compilation

$ make compile

browserify & make-commonjs-depend

To verify the text below you'll need to clone this repo, run 'make compile' & install [make-commonjs-depend].

Look into repo's test/data directory. Ignore *.should files. I'll wait.

Then

$ cd src
$ ls *coffee
syscmd([ls *coffee])

Here main.coffee depends on a.coffee & b.litcoffee. For out site we need just 1 public/bundle.js file which will include the result form the compilations of our all CoffeeScript files.

We want to rebuild public/bundle.js only & only on .coffee files change. That's obviously a job for make.

$ cat Makefile
include([Makefile])

To create a dependency tree, we run

$ make depend
syscmd([make depend | egrep -v '(Entering|Leaving) directory'])

$ cat js.mk
include([js.mk])

It's unfortunate that make-commonjs-depend supports only javascript. That's why before running it, make needs to compile all coffescript files.

Then compile the bundle

$ make compile
syscmd([make compile | egrep -v '(Entering|Leaving) directory'])

As a little homework, try to guess why main.js was recompiled here, when at first glance it should rather not.

Run again

$ make compile
syscmd([make compile | egrep -v '(Entering|Leaving) directory'])

Notice that the nothing was recompiled for the 2nd time. That's our goal!

$ touch a.coffee
$ make compile
syscmd([touch a.coffee; make compile | egrep -v '(Entering|Leaving) directory'])

Yay! Then open public/index.html in Chrome and switch to the console view. (Make sure to turn on 'Enable source maps' in Developer Tool's settings.)

Jeez mate, why are you doing this rigmarole?

Every dependency & every file should be compiled/processed only once.

This seems meaningless for a bunch of small .coffee files but becomes very useful for large projects with several complex browserify output targets.

Why not just use coffeeify plugin for browserify?

1. browserify can't (& shouldn't) check changes in our source files to decide whether it's time to recompile.
2. Error reporting.

Why are you using outdated make instead of cake, jake, grunt, gulp or broccoli? It's not 1977 anymore!

Dude. Take a walk for 10 minutes & no one will get hurt.
