JAWR css/Javascript combine and compress module

[John Pletka]

I'm looking for a module similar to http://grails.org/plugin/jawr that will automatically combine,compress and version a group of javascript and css files.  I've looked at the Press module (http://www.playframework.org/modules/press) and GreenScript (http://www.playframework.org/modules/greenscript), but they only do the compression.  Does anything like that exist out in Play land?

press (and I think greenscript) will compress and combine.
Could you be more specific about what functionality is missing? Maybe I can add it to the press module.

That great!  From the description on the modules page, I thought it was only using the YUI compressor.  It does not appear to work properly with the latest 1.1 nightly build though.  It creates the "press" directory but fails to write the file into it.

press will aggregate and compress into a single archive any javascript files that have been added with the {press.script} tag. You also need to output a {press.compressed-script} tag to indicate where to output a reference to the archived file.
By default compression is disabled in dev mode, and enabled in production mode.

There's more information in the documentation:
http://www.playframework.org/modules/press-1.0.1/home

Have you replaced all <script> tags with {press.script} tags, and included a {press.compressed-script} tag? If so, check that you have a line like the following in application.conf:
press.enabled=true

If you're still having problems please send me some example code so I can try to work out what might be the problem

I've tried Press with both play-1.1-unstable-r982 and play-1.0.3.2 and got the same behavior (compressed file not written)

In my main.html template, I have:
#{press.stylesheet 'main.css' /}
#{press.stylesheet 'reports.css' /}
#{press.compressed-stylesheet /}

In my application.conf
module.press=${play.path}/modules/press-1.0.1
press.enabled=true

My css is in:
/public/stylesheets

Press creates a directory /public/stylesheets/press automatically, but the combined file is not written into it.

Could you also give an example of the html it generates as well? Not the whole document, just the part where it outputs the javascript files. Also, please check the output window/logs for errors (if you are running play with "play run" it will show exceptions in the console, otherwise in logs/system.out).
Thanks for your persistence!

Could you please set your log level to TRACE in application.conf (look for the line like this: "# application.log=INFO" and change it to "application.log=TRACE"). Press will output a bunch of debug info saying what it's doing, with each line prefixed with the word "Press: ".
Please send anything relevant you find.
Thanks again!
