[[!template id=plugin name=texinfo author="[[tschwinge]]"]]
|
|
|
|
[[I|tschwinge]] started writing a plugin to render
|
|
[GNU Texinfo](http://www.gnu.org/software/texinfo/)
|
|
inside the ikiwiki environment.
|
|
|
|
This plugin is not neccessarily meant to enable people to write arbitrary
|
|
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://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.

# Issues
|
|
|
|
## How can I use verbatiminclude?
|
|
|
|
I only can post a file ...
|
|
|
|
## N-to-M Mapping of Input and Output Files
|
|
|
|
Conventional ikiwiki [[*htmlize*ing|plugins/write#index6h3]] plugins
|
|
have a one-to-one mapping of input file and output file:
|
|
`some/where/page.mdwn` is rendered to `some/where/page.html`.
|
|
This can also be achieved for Texinfo files, but is somewhat
|
|
unusual there, when rendering them to HTML. In general, there
|
|
is a N-to-M mapping:
|
|
|
|
* 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`. --[[tschwinge]]

|
|
|
> As far as multiple input files, you'd need to use add_depends()
|
|
> to let ikiwiki know that a change to any of those files should cause a
|
|

|

|
|
>> the others. --[[tschwinge]]
|
|
|
|
* 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. --[[tschwinge]]

|
|
|
|
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
|
|
|
|
`makeinfo --html` is being used for rendering. It creates stand-alone
|
|
HTML files, while ikiwiki only needs the files' `<body>`s.
|
|
|
|
(?) 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.
