How do I enable --debug for node.js when running GeddyJS

Question

GeddyJS is started by running geddy from the root of the project.

I'm having some trouble getting GeddyJS to run under node.js with debug enabled.

getty installs /usr/local/bin/geddy:

#!/usr/bin/env node
...

which I made a quick copy of, and amended the shebang line:

#!/usr/bin/env node --debug
...

but that does not work, because env can't find 'node --debug'.

I then tried to write a wrapper script to act as the interpreter in the shebang line here:

#!/bin/sh
exec /usr/bin/env node --debug $@

And this time, node is started with a debugger enabled, but the paths must be messed up, or environment must be different, because I am getting missing module exceptions:

$ geddy-debug
debugger listening on port 5858

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: Cannot find module '../lib/geddy'
    at Function._resolveFilename (module.js:332:11)
    at Function._load (module.js:279:25)
    at Module.require (module.js:354:17)
    at require (module.js:370:17)
    at Object. (/usr/local/bin/geddy-debug:4:1)
    at Module._compile (module.js:441:26)
    at Object..js (module.js:459:10)
    at Module.load (module.js:348:31)
    at Function._load (module.js:308:12)
    at Array.0 (module.js:479:10)

This of course works fine if I don't try to enable debugging.

I want to debug in eclipse as per : https://github.com/joyent/node/wiki/Using-Eclipse-as-Node-Applications-Debugger, which works great with just node --debug scriptname.js

Any suggestions are appreciated.

It looks like Geddy has a `--debug` option. Does that only debug Geddy, not Node? — loganfsmyth, Feb 26 '12 at 02:56
It seems to set the log verbosity level, but does not enable node's --debug option. — dwerner, Feb 26 '12 at 08:57

Answering my own question, so others can benefit if they happen to see this:

From the project directory, override the shebang line and invoke the interpreter directly to run the geddy script:

/usr/bin/env node --debug /usr/local/bin/geddy

How did this turn out for you? I'm trying to debug a geddy app as well when I found this: http://stackoverflow.com/questions/9587655/no-breakpoints-are-hit-with-geddy I'm not able to set/hit any breakpoints. Were you? – prodaea Sep 28 '12 at 16:54

I ended up ditching geddy. I found a better path through express.js to build my app at the time. – dwerner Sep 28 '12 at 20:03
I came to the same conclusion. I'm using express now and I'm looking to move on to flatiron possibly. – prodaea Oct 11 '12 at 20:27
