CSS hackers needed.
Yes, the first test version of roojs1 is built and working you can have a look here to see the old ExtJS1 examples (which where sourced from a 0.40 release licenced under a BSD licence)
http://www.akbkhome.com/roojs1/examplesWarning this may break occasionally as I do daily builds of the library Most of the main layout, windows, grid and tree work pretty well, but there are some problems with toolbars, menus and forms. Basically I could not find complete licence free sources for any of them. So if you know anyone who can create CSS for the missing parts (and can illustrate reasonably well that it was not based on the original ExtJS CSS) send them over this way. That will help RooJS2 as well, as the CSS is probably pretty similar.
Have a look at
http://www.akbkhome.com/roojs1/css/roojs-debug.css for details on the status of the css build..
A big leap forward in building a truely free high quality JS UI toolkit.
Anyway onto my geeking techo fun.Rooscript compressor
As part of the whole build toolkit, I've ported the yui compressor to rooscript (the dmdscript based Javascript interpreter), The results are pretty good.
The current output from the compressor is 8K less that the ~497K that ExtJS 1.1.1 files are (built I presume using yui compressor). Along with this, it's pretty easy to tweak, and remove Files and add your own application (eg. create an all in one javascript file for your application)
Speedwise I've been trying to get the compressor to go faster (It normally caches the minification result to a file and can do a 'reparse' in arround 2 seconds, but for a fresh build it takes about 6 minutes to parse all the ~100 files in Roojs1
In the process of speeding it up, I've added a few switches to rooscript
- -p for a very simple profiler (gives you the total time taken for all the opcodes exculuding call/new etc. in each function) along with how many times they where called.
- -U to turn on Unicode for strings, as I've disabled it by default, although I'm not that sure now, that it produced the speed hit that I thought it might. ** mostly affect things like xx.indexOf("\n")
- -d (to show all the opcodes as they run) - old but handy sometimes...
The code is reasonably simple, so If you have any great ideas on how to improve compression, it's extremely easy to test how well they work. (rather than the usual compile/run cycle that all the Java versions have)
In looking at the resulting code, one simple opmization that I've started adding to RooJs is changing the constructor code in the object from Roo.data.Connection.superclass.constructor.call(this,....) to Roo.superC(this,....) and Roo.data.Connection.superclass.somemethod.call(this,....) to Roo.superM('somemethod', this,.....)
I'm guessing that's could be ~ 2K of rather wastefull code removed..
Basically since the compressor is working now, I'm going to re-look at the Docs, and sort out the bug's in those - probably replacing the scoping code in jsdoctoolkit, with something closer to the ported yui compresser version.
