Stage3D is a relatively new addition to Adobe Flash player and compiling shaders can be difficult and cumbersome to write in AGAL.
HLAG is a compiler written in Adobe AIR that compiles a high level shader language to AGAL instructions for use in Flash or AIR Stage3D. It has an integrated preview window to test shaders after compilation with tools to manipulate shader parameters in real time. It also supports multiple passes and preprocessor constant permutations for export. Shaders are exported as XML data that can be parsed and integrated in to any Stage3D application.
This version is a windows stand alone application for this release but will be provided as an AIR application for multiple platforms after the test releases. There is currently no scroll bar for the source window but you can use the mouse wheel as a replacement for the time being. The UI parts still need a lot more work but the compiler and export tools should all work correctly. There will be bugs which is why it is currently just an alpha test release.
Documentation will be provided soon but for the time being you can use F1 to bring up some information on keywords and there are some basic starting templates provided. I hope to keep this application free to use for hobby or commercial purposes. More information is provided on the website:

I'd be interested to hear feedback through this post or the contact me section of www.jrmcv.co.uk. Hopefully some people will find this useful for their own AIR/Flash projects .
My main website wasn't written using HLAG but it inspired me to write HLAG after a lot of the headaches I had with the shaders.
