vjeux / watcher

Recompile your Coffee/SASS/Haml/Less/... files as soon as they change

• You have a lot of CoffeeScript, Haml, Sass, Jade and Stylus ... files and you want them to be automatically compiled when you save.
• You don't want a full "IDE" like LiveReload, CodeKit or Compass.
• You like coffee --watch mode.

Install

npm install -g watcher

Command Line

Output in the same folder

watcher src/

Output in the bin/ folder

watcher -o bin/ src/

Watch a single file

watcher src/application.coffee

Output Example

Let's start the watcher, it compiles everything it finds.

22:36:30 - compiled src/index.haml
22:36:30 - compiled src/soulver.coffee
22:36:30 - compiled src/soulver.less

Oops, we made an error:

22:36:56 - compiled src/soulver.coffee
bin/soulver.js: Error: Parse error on line 2: Unexpected '''
    at Object.parseError (/usr/local/lib/node_modules/coffee-script/lib/coffee-script/parser.js:470:11)

    at Socket.emit (events.js:64:17)
    at Pipe.onread (net.js:348:51)

We fix the problem, save again and it goes back in order :)

22:37:15 - compiled src/soulver.coffee

Just Ctrl+C when you are done editing the files.

watcher's Issues

Please update npm package

right now the npm package doesn't work..

path.exists is now called `fs.exists`.

events.js:72
        throw er; // Unhandled 'error' event
          ^
Error: This socket is closed.

I can see the issue is fixed in this repo, but the npm package hasn't been update in 2 years..

npm install watcher fails

I had a problem to install your package so I filed an issue on https://github.com/isaacs/npm/issues/2186. Please have a look at it. Hopefully I will be able to try your package later.

Add -c to compile only

Handle dependencies?

# main.less
@import "file.less";

When file.less is updated, it would be great to recompile main.less instead of compiling the useless file.less

Different directories for each type

We may not want to output HTML and JS files in the same directory.

Maybe an option

watcher --output-html html/ --output-css css/ --output-js js/ src/

Generate file but no content

watcher folder/
show this:
path.exists is now called 'fs.exists'.

folder\file.jade.html: CreateProcessW: The system cannot find the file specified.

by the way I'm in Win8 with Node.js in command prompt :/ thanks a lot
