Coffee script compilation

Question

I'm looking for simplest possible way to automatically recompile coffee scripts into JS.

Reading documentation but still having troubles to get exactly what I want.

I need it to watch folder src/ for any *.coffee files modifications and compile them into concatenated javascript file into lib/something.js.

Somehow can't combine watching, compiling and concatenating together. :/

Answer 1

Changed mind about concatenation.
Created small compiler.sh file which contains:

dnotify -M src/ -e coffee -o lib/ -c src/ &
dnotify -M spec/ -e coffee -o lib/ -c spec/ &

Kind a suits my needs.

Answer 2

find `pwd` | grep .coffee | xargs coffee -w -c

try this one in root directory of the application

Answer 3

Well coffee --watch has 2 major flaws:

• New files created after command has been issued aren't being watched
• Requires manual initiation so there can be a chance you forget to do it, which doesn't sound more brilliant than forget to compile before you git commit it

The solution I came up with is a rather simple Bash script that takes coffee --watch a few steps further which will allow your working directory tree to be watched ever since system login, and automatically get compiled into JavaScript on each file save/change or new file creation:

There may be more elegant way to do this, but this implementation works great =)

Answer 4

find -type f | grep .coffee | xargs ls -t | head -n 1 | xargs coffee -cw

find last modifed coffee script and put it in compile-watch mode

Answer 5

nodemon -x coffee server.coffee does it for me.

Install nodemon using npm install -g nodemon
