[[!tag patch wishlist]]I quite often find myself repeating a boiler-plate
|
|
pagespec chunk, e.g.
|
|
|
|
and !*.png and !*.jpg...
|
|
|
|
it would be quite nice if I could conveniently bundle them together into a
|
|
pagespec "alias", and instead write
|
|
|
|
and !image()...
|
|
|
|
I wrote the following plugin to achieve this:

I need to reflect on this a bit more before I send a pull request. In
|
|
particular I imagine the strict/warnings stuff will make you puke. Also, I'm
|
|
not sure whether I should name-grab 'alias' since [[todo/alias_directive]] is
|
|
an existing wishlist item.
|
|
|
|
Here's an example setup chunk:
|
|
|
|
pagespec_aliases:
|
|
image: "*.png or *.jpg or *.jpeg or *.gif or *.ico"
|
|
helper: "*.css or *.js"
|
|
boring: "image() or helper()"
|
|
|
|
The above demonstrates self-referential dynamic pagespec aliases. It doesn't work,
|
|
however, to add ' or internal()' to `boring`, for some reason.
