shebang and node

[Urban Hafner]

Hej all,

I don't have the setup to try this right now, but would something like
this work with current node?

#!/usr/bin/env node

// Code goes here

It would be nice to write everything in node itself (for example a
simple test runner for my library or a script to concatenate files).

it doesn't because # is not a comment symbol in javascript.

but that would be very cool indeed.

Ah, right. I forgot.

That could be added easily - and I like the idea. Does anyone want to
give it a shot?

Look at the bottom of the file src/node.js - there it loads the
root_module, the module which was given on the command line. The file
can easily be scanned for a shebang (use a regexp) and removed before
compiling it (see node.compile() in node.Module.prototype.load()).

Well, it shouldn't be a major undertaking to either add a `nodescript`
executable or a command line flag to indicate "ignore the first line
of the script if it's a #.

I got around this one temporarily by having an executable bash script
evaluated a node script:

#!/bin/bash
eval "node server.node";

But yeah, regular expression to avoid this overhead would be sweet.

Added in 6acac91.

self.target.__require = function (path) { return
self.newChild(path, {}); };
self.target.__include = function (path) { self.newChild(path,
self.target); };

+ // remove shebang
+ content = content.replace(/^\#\!.*/, '');
+
// create wrapper function
var wrapper = "function (__filename) { "+
" var onLoad; "+

Module loading isn't working yet from shebang scripts (unless they're
specified with a full path :P), but this handles the most trivial case
and encourages myself to finish it.
