[[!template id=gitbranch branch=wtk/raw_inline author="[[wtk]]"]]

summary
=======

Extend inlining to handle raw files (files with unrecognized extensions).

Also raise an error in `IkiWiki::pagetype($file)` if `$file` is blank, which avoids trying to do much with missing files, etc.

I'm using the new code in my [blog][].

Reviewing your patch the first thing I see is this:

<pre>
+        if (! $file) {
+               error("Missing file.");
+        }
</pre>

This fails if the filename is "0". Also, `pagetype()`
currently cannot fail; allowing it to crash the entire
wiki build if the filename is somehow undefined seems
unwise.

I didn't look much further, because it seems to me what you're trying to do
can be better accomplished by using the highlight plugin. Assuming the raw
file you want to inline and comment on is some source-code-like thing,
which seems likely.

Or, another way to do it would be to use the templates plugin, and make
a template there that puts an inline directive inside pre tags.

If `pagetype()` cannot fail, then I suppose that check has to go ;).

I was under the impression that [[plugins/highlight]] didn't support
inlining code.  It looks like it supports highlighing stand-alone
files or embedded code.  Perhaps I should extend it to support inlined
code instead of pushing this patch?

The `raw.tmpl` included in the patch *does* include the inlined
content inside `pre` tags.  The problem is that the current inline
code insists on running `htmlize()` on the content before inserting it
in the template.  The heart of my patch is an altered
`get_inline_content()` that makes the `htmlize()` call dependent on a
`$read_raw` flag.  If the flag is set, the raw (non-htmlized) content
is used instead.

I just rebased my patches against the current Ikiwiki trunk (no major
changes) to make them easier to review.
