There is a lot of interest in Node, and a lot of work to do.  Several
of you have asked me lately how you can help in IRC and in person.

In order to try to help match up the interest with the work, I'm going
to start occasionally making requests for help in specific areas where
I think improvements need to be made.  In the past, these kinds of
calls have been very productive.

You don't need permission.  Just play around with the problem, and if
you make some headway, share it with the rest of the group.  If you
find it's something you really can get excited about, then maybe it
can be your thing :)


A very problematic area right now is binary module compilation across
platforms, especially on Windows.

In the past, we've deployed a node-waf program, which is a
lightly-customized fork of the "waf" build tool.  This program has
worked ok, but it is fundamentally non-portable, and my hope is that
it will not have to be in 0.8.

In the node source tree is a file called tools/gyp_addon.  You can use
this to generate either a Makefile, or the appropriate MS Visual C
stuff to build an addon.  There are some examples in test/addons/, but
the whole process is not very well documented, and requires a lot of
manual tweaking.

To make matters even more hairy, there are a bunch of node programs
floating around in the wild that are using node-waf.  We need to make
it as easy as possible to port these to a better future.


The goal:

There should be a standalone `npm install addon-gyp-toolchain -g` or
something (probably ought to pick a better name) that sets up some
scripts.  If you have this toolchain installed, we'll assume that you
also have "make" on unix, and Visual Studio on Windows.  If you then
run the appropriate command in a project directory, it'll build an
addon using whichever method is appropriate for the current system.

Once such a thing is in place, and it works reliably on Windows and
Unix, and is pretty easy and generalized, start making pull requests
to everybody to replace their wscripts with a gyp file.

The most important thing is that it makes the process easier than it
is today.  There's probably more API design, debugging, and picking
through bits, than actually writing new code.

And, of course, it could be that my vision of this is way off.  Your
task should be to make it easier to compile a bunch of C code into a
.node addon file in a way that works on Windows and Unix, and doesn't
completely suck.  Don't be afraid to get creative.



Why not just deploy gyp_addon with node?  Because that would be
recreating the node-waf experience, which is terrible.  This is a step
towards binary deployments (at least for operating systems and
platforms that can do such things reliably).  It would not be terrible
to install it when node is configured with --debug or something, but
by default the msi and pkg installers should never include gyp.  Users
who *want* install-time compilation will always be able to do this by
installing the toolchain and then opting out of binary builds.


Thanks for your help.
