pHAML - Smarty Haml
Even though its capitalized correctly as “Haml”, here is another attempt at a PHP templating language inspired-by-Haml.
Looks pretty interesting, actually. Though, I haven’t done PHP in a long time and haven’t gotten a chance to look at it closely. Apparently it uses the Smarty system to do most of the rendering dirty work, which is pretty smart. We were considering early on compiling into ERB, but in the end shied away from it. Anyhow, pHAML has some interesting stuff like a debug-mode that is started by the ? character on a line. I’d love to read a tutorial on how it works, but right now, I don’t have the time to dive back into PHP. ;)
