Are there any plugins for eclipse that add syntax highlighting and other niceties for editing Haml and Sass? Google searches only seem to point to a dead project on lucky-dip.net.

Note: it’s Sass I’m most interested in. A solution for using just Sass (or something similar to it like less) in Eclipse would suit my needs.

Also, I’m developing for Google App Engine (Java), using the App Engine plugin for Eclipse. So switching to another IDE isn’t an option.

Update: So I’ve got syntax highlighting now using Pascal’s answer and I’ve installed Ruby and Compass to compile sass into css.

However I’m aware that the syntax of sass will be changing with 2.4 so I’d still like to get the Haml and Sass Editors that come with Aptana to work. When I tried to use them they threw an exception and wouldn’t display the files. I’d be interested to know if that’s because I misconfigured Aptana or is an actual bug in the editors.

I’d also be very interested in any way of compiling Sass that integrated with Ecplise so that I didn’t have to run something separate from it. (or a way of putting Sass/Compass in the Ecplise build process.)

    Well, what about Aptana? According to the Haml/Saas Syntax Highlighting in Aptana/Eclipse blog post:

    Recently, I have been using Haml in
    some my Rails projects. It simply
    makes your views clean and readable.
    One issue I had was syntax
    highlighting in my favorite IDE,
    Aptana Studio. The Haml syntax
    highlighting support     has been stopped
    a while ago and more issues have
    raised after Aptana recent updates.

    After some research, I found a
    solution posted by Max Kostovetski, a
    member of Haml Google group. Now, to
    the steps:

    1. Download the following files to your hard drive:>
    2. From AptanaEclipse “Window” menu, select “Preferences…”
    3. In the the preferences window, select “Editors” > “Generic Text”
    4. Press “Add…” to add new file extensions: *.haml and *.sass
    5. For each of the new extensions, click it and press “Browse…” to
      select the proper lexer file (*.lxr)
    6. For colorization, press “Import…” to import the *.col files
    7. Press “OK”
    8. Enjoy you Haml views

    PS: Refer to the original blog post as it provides up-to-date links.

    Note: this can be used with the Aptana RadRails Eclipse plugin as well as Aptana Studio

    UPDATE: At the time of writing, RadRails and Studio seems to support Haml and Sass so it might now be unnecessary to follow the steps above.

    To compile SaaS in an “integrated” way inside Eclipse, you could maybe just use an External Tool (Run > External Tools). Another more elaborated option would be to add a “Program Builder” to your project’s Builders like in this blog post. Of course, the described solution would require to be adapted to Saas but the principles behind it seems to apply. Caution: I didn’t implement it myself, it’s just an idea and I’m not even sure it makes sense.
