Replace ant with Grunt

[baalexander]

Just because JavaScript has Java in it, doesn't mean we need to use an antiquated build environment. I'll assign this to me unless someone else wants to look at it first.

I see no reason to use something fancier for concatenating files together. The (large) advantage of using ant is the fact that it comes ready-to-roll on any Ubuntu system. Grunt, from what I can tell, is early so I went with something more stable for such a simple task.

If it was just concatenating files, maybe. But we can do a lot more, like doc generation, linting, running tests, and minification with grunt.js.

[rctoris]

It does that too:

minification:

<target name="-minify" depends="-concatenate" description="Minifies JavaScript files"> <exec failonerror="true" executable="${yui}"> <arg value="${build}/${js}" /> <arg value="-o" /> <arg value="${build}/${js.min}" /> </exec> <echo>${js.min}created.</echo> </target>

JS Doc (btw, I added JS doc to everything and it gets generated in the doc folder)
<target name="-doc" depends="-minify" description="Documents JavaScript files"> <exec failonerror="true" executable="${jsdoc}"> <arg value="-d=${doc}" /> <arg value="${src}" /> <arg value="-r" /> </exec> <echo>JSDOC created.</echo> </target>
