[[I|tschwinge]] started writing a plugin to render
[GNU Texinfo](http://www.gnu.org/software/texinfo/)
inside the ikiwiki environment.
wiki pages in the Texinfo format (even though that is possible, of course),
but rather to ease collaboration on existing Texinfo documents.
-The plugin is available at <http://www.schwinge.homeip.net/~thomas/tmp/texinfo.pm>.
+The plugin is available at
+<http://git.savannah.gnu.org/cgit/hurd/web.git/plain/.library/IkiWiki/Plugin/texinfo.pm>.
It's very basic at the moment, but will be improved over time.
+It also has not really been audited for any security issues.

## N-to-M Mapping of Input and Output Files
Conventional ikiwiki [[*htmlize*ing|plugins/write#index6h3]] plugins
* N Texinfo input files (a main `.texi` file,
several helper files (`fdl.texi`, `version.texi`, ...), and
additional text files which are included from the main `.texi`
- file, e.g. `history.texi`, `libfoo.texi`, `libbar.texi`.
-* M Texinfo output files: the main `.texi` file (which `include`s
- the other input files) is usually rendered into a (flat) hierarchy
- of HTML files, one file per node, see the table on
- <http://www.gnu.org/software/texinfo/manual/texinfo/html_node/#Top>
- for an example.

+There needs to be some logic to establish a mapping between the *N* input files
+and the *M* output files.
+(At least for web-editing via CGI this is needed: ikiwiki (currently) needs to be able
+to deduce *one* input file from a given output file)
+Easiest would be either to have *N = 1*
+(plus perhaps some input files that are not meant to be editable, like `gpl.texi`)
+or to have
+*M = N* and have a (?) one-to-one mapping between *input file n* and *output file m*
+(which is not possible in Texinfo's `makeinfo` at the moment).

## `makeinfo` Output
(?) One possibility (which is what I'm doing at the moment) is to simply cut away
everythin until `<body>` is seen and after `</body>` has been seen. --[[tschwinge]]

+# Bugs
+
+## Non-functional Texinfo Commands
+
+Those commands are know to not work currently:
+
+* `@printindex`
+* `@shortcontents`
+* `@contents`
+
+This is due to `makeinfo` not providing this functionality if rendering to stdout.
