RooJS update - form CSS, better docs, and compressor eval hints. : RooJSolutions

Another update on progress on RooJS (the ExtJS v1 Fork)

The CSS was created by documenting how the existing examples where rendered in ExtJS - A document describing this was created (see form_design.svg in the css folder). Then that document was used to create a brand new CSS file. I believe this can be regarded as not breaking the copyright and having a reasonable reverse engineering process.
the x-box borders are missing, although not critical
the HTML editor needs to be fixed.

I have done the design diagram for CSS of the menu's and will be working on that soon.
The doc's are improving as well, The doc's appear to be listing all the correct elements now, future work will focus on tidying up the templates.

Most of the improvements came from replacing the Walker code in the jsdoctoolkit so that it understands scope in a similar way to the compressor. I also had to add a few extra comments in the source to give the documentation tool a few hints.
/** @scope Roo.somescope */ -- changes the scope in the documentation engine (as sometimes it just can not guess what the scope is.
/** @scopeAlias avar=Roo.xyz.prototype */ -- adds an alias to the parser engine alias map, so when it sees 'avar', it will replace it with Roo.xyz.prototype

The compresser is working well, someone asked on #roojs on freenode about using it for other code, including ExtJs2.0 - There should be no problem doing that - have a look at the bundle build file to see how to set up a builder for any project.

One thing to note is that the compresser uses hints when it sees 'eval'. The YUI compresser basically turns off compression for a large chunk of the code if it sees 'eval', I've added code to pick up a comment before the eval statement:

/** eval:var:abcd */ will turn variable compresion back on, and exclude 'abcd' from the list of variables to be compressed (use multiple eval:var:... statement on multiple lines to exclude multiple variables)

Anyway back to work tommorow, after celebrating (eg. doing nothing) the glorious reunification with the motherland day (HKSAR day)
