wmii is cool since it's configurable with *ANY* language. As a rubist I use ruby-wmii by Mauricio (who is well known as mfp).

One problem is you can't assign shortcuts to resize a window in the latest wmii release. I asked for this in wmii's mailing list and luckily Kris, the author of wmii, quickly replied and implemented this. It's great, but the new problem is I found that WMII_ADDRESS, a environment variable, which will be set when wmii start in latestest stable release, does no longer exist in development version. And ruby-wmii will ask for it when wmii starts, so in one sentence, wmii version 'hg2307+' won't work with ruby-wmii.

Have no time to dig more, just create a quick patch to fix this:

around line#96 In cmd/wmii/main.c

Original:

    if(address)
        setenv("WMII_ADDRESS", address, true);
    else
        address = smprint("unix!%s/wmii", ns_path);

To:

    if(!address)
        address = smprint("unix!%s/wmii", ns_path);

    setenv("WMII_ADDRESS", address, true);

May post a better solution later.
