I’ve recently re-installed OSX and lost my quicklook support for .mxml and .as files. Since I couldn’t find whatever packages I had installed that allowed that quicklook support, I’ve modified QLColorCode to add support for previewing both .as files and .mxml files.
It works on my computer and I hope that it’ll work on yours too.
Please feel free to download my version, qlcolorcodeqlgenerator unzip and install, let me know if it doesn’t work.
Installation instructions for quicklook plugins can be found here.
