So I've been actually trying to use Apoche::Test to test this module and I'm slowly getting there. It's quite swish when it works (we don't use it ourselves at work because apparently it's too clever and autodetects things outside of our build system!) I'm currently playing with writing dummy AxKit lanaguages that unconditionally dump different things in the pipeline so that I can test that the TT language reads and understands the previous data from the pipeline fine.
Once I've got the basic version done there's still big problems ahead. Firstly, there's the issue of caching. Currently I'm creating a new TT object every time, which means that every single time a TT stylesheet is used it's turning the template into Perl code. This is about ten times slower than reusing an existing lump of code. So I need to somehow merge TT's providers with AxKit's providers so that caching works. Which should be fun. The second major issue is configuration. As far as I can see it atm, the configuration for things like INCLUDE_PATH that kip's already done is on a per server not per stylesheet basis (or perl Location block directive). I'm not sure what the right thing to do here is...I'll have to give it some thought.
Anyway, slowly but surely.
