Configurable paths

[vojtajina]

The path - cache key needs to be configurable.

Guys, any ideas on how to call that config ? cacheIdFromPath ?

I'm gonna make it a function that transforms the filepath into the cache key. By default, it's gonna be identity...

So you could pass in another function, which could transform the key in an arbitrary way? That could work. Alternately, the main use-case I see for this is the one we ran into, where your templates are loaded w/ a root-relative URL path. In that context, all we would need is the ability to specify a prefix to be appended to the cache key, similar to basePath.

The former is more flexible, while the latter is simpler.

prefix to basePath would be simpler... but sometimes it's not enough... (you might want to remove some prefix as well)

eg. you have directory basePath/app/tpl/*.html and your web server serves them as /static/tpl/*.html.

So I think, there are two options, I definitely wanna keep it simple.

1/ a transform function that takes the filepath (relative to basePath) and returns the $templateCache key, by default, it's identity function

2/ prependPrefix and stripPrefix (both default to an empty string); stripPrefix is stripped from the relative filepath, prependPrefix is prepended to the filepath.

I'd vote for # 1 (transformation function), it seems to be the most explicit.
