[[!tag wishlist patch]]
# Context
I may have missed a simple way to achieve what I need without
modifying ikiwiki, so here is the context.
I have a first-level directory (called `bricks`) containing a bunch of
wiki pages :
/bricks
|
|- bla.mdwn
|
|- bli.mdwn
|
`- ...
I have two groups of tags called `direction` and `usage`, stored in
two sub-directories of `$tagbase` :
/tag
|
|- direction
| |- d1.mdwn
| |- d2.mdwn
| |- ...
|
|- usage
| |- u1.mdwn
| |- u2.mdwn
| |- ...
Any page in `/brick` can be tagged with one or more tags from any of
these tags-groups.
I need to present different views for these wiki pages, so a `/view`
tree is dedicated to this mission :
/view
|
|- dev
| |- d1.mdwn
| |- d2.mdwn
| |-...
|
|- howto
|- u1.mdwn
|- u2.mdwn
|- ...
... where e.g. `/view/dev/d1` lists a subset (depending on other tags)
of the pages tagged d1.
My current plan is :
- thanks to the edittemplate plugin, `/view/dev/*` and `/view/howto/*` would contain respectively `\[[!template id=dev_direction]]` and `\[[!template id=howto_usage]]`
- `/templates/dev_direction.mdwn` and `/templates/howto_usage.mdwn` would use `\[[!map ...]]` directives to build their views
# My issue
Such map directives would look something like the following (more
complicated, actually, but let's focus on my current issue) :
\[[!map pages="bricks/* and link(tag/usage/<TMPL_VAR BASENAME>)"]]
Where `BASENAME` value would be, e.g., `u1` or `d2`, depending on the
page inserting the template. But `BASENAME` does not exist. I found
that `<TMPL_VAR PAGE>` is replaced with the full path to the page, but
I did not found how to get the page's basename in a template included
with a `\[[!template id=...]]` directive.
Any idea ?
I guess it would be possible to provide the templates inserted by the
template plugin with more `TMPL_VAR` variables, but I don't know ikiwiki
codebase well, so I don't know how hard it would be.
I sure could write a ad-hoc plugin that would use the pagetemplate
hook to add a custom `<TMPL_LOOP>` selector I could use in my
templates, or another one that would use the filter hook to add the
needed `\[[!map ...]]` where it belongs to, but since ikiwiki's
preprocessor directives already *almost* do what I need, I'd like to
avoid the ad-hoc plugin solution.
(Adding a parameter such as `name=d1` in every `/view/dev/d*.mdwn` and
`/view/howto/u*.mdwn` page is not an option : I want to factorize the
most possible of these pages.
