Use local commands

[ashmoran]

Didn't think about this until working on Spork, where you want to use the local binary. (Unlike, say, working on cucumber-rails, where the relevant binaries come from other projects.)

Currently I'm putting this at the top of Spork's env.rb:

ENV["PATH"] = File.expand_path(File.dirname(__FILE__) + "/../../bin") << ":" << ENV["PATH"]

This is to avoid any facepalm moments in future where I change Spork code and don't re-install the gem. Question is, does Aruba need a step for this or an API means of making it easy? eg

Given $PATH includes "bin"

(which I don't like)

[aslakhellesoy]

Aruba should work well for command line apps in general (not only Ruby ones).
I don't think it should have magic for the bin folder.

Can't you just do:

When I run "bin/spork"

Or am I missing something?

[ashmoran]

Yeah I thought that. But the problem is figuring out what "bin" is relative to. The above won't work, for example, if your project dir isn't in the PATH.

The problem is that as soon as you install the project gem, the command appears in the PATH, but it won't be running the code you actually want to test. It's a subtle gotcha.

This is fixed on master now.

Cool cheers Aslak.
