Note: This is taken from the Chicken Wiki, where a more recent version could be available.

This is version 0.1 of the eggdoc-svnwiki extension library for Chicken Scheme.

Description

Render eggdoc source to svnwiki syntax

Documentation

eggdoc-svnwiki produces svnwiki output for Chicken eggs from eggdoc SXML source.

Your eggdoc and you

procedure: (eggdoc->svnwiki DOC [STYLESHEET])

Transform the SXML document DOC into svnwiki format using the optional SXSLT stylesheet STYLESHEET. If not specified, the built-in stylesheet will be used, which is also accessible with eggdoc:make-svnwiki-stylesheet.

procedure: (eggdoc:make-svnwiki-stylesheet DOC)

Returns the default SXSLT stylesheet, which transforms eggdoc input to svnwiki output. This is a procedure because the stylesheet is built dynamically using the contents of the SXML document DOC.

You can append to or modify this stylesheet and then pass it to eggdoc->svnwiki.

procedure: (eggdoc:make-defsig TAG SIG . [BODY])

Use this procedure inside a stylesheet to generate a new signature tag, just like procedure or macro. It expands to a (definition (signatures (signature ...))) expression. For example,

(eggdoc->svnwiki doc `( ,@(eggdoc:make-svnwiki-stylesheet doc)
                        (constant *macro* . ,eggdoc:make-defsig)
                        (method   *macro* . ,eggdoc:make-defsig) ))

will create new constant and method tags.

Batch conversion

Inside the egg under extras/ I included some simple scripts to help with conversion of one or more eggdoc sources to svnwiki format.

eggdoc-svnwiki-shim.scm: Overrides standard eggdoc functions with eggdoc-svnwiki versions, so you do not have to modify the source.
eggdoc-html-to-svnwiki.sh: Converts standard eggdoc source to svnwiki plain text.

Limitations

This extension has only been tested on a few eggs, unlike eggdoc-texinfo (which was tested on a hundred). There are undoubtedly unresolved formatting issues that will be encountered. Additionally, svnwiki has some peculiarities and bugs of its own. Overall, however, the conversion quality is not too bad.

Nested lists are not handled
Nested definition lists won't render correctly (limitation of svnwiki)
#xxx at beginning of line or within <td> is rendered as list (svnwiki bug)
Certain eggdocs may contain extraneous whitespace; if at beginning of line, may result in inadvertent PRE.
Escaping of command characters is not really bothered with.
Table attributes are ignored (limitation of svnwiki)
All other attributes are ignored except for href
Etc.

Examples

For the direct, tedious approach, edit the source and change the eggdoc->html call to eggdoc->svnwiki, and (use eggdoc) to (use eggdoc-svnwiki), then just call the eggdoc source script.

To use the example script to convert existing eggdocs, unpack the egg and run the conversion script against the desired source:

~/scheme/eggdoc-svnwiki$ mkdir output
~/scheme/eggdoc-svnwiki$ sh extras/eggdoc-html-to-svnwiki.sh ~/eggdoc/eggdoc-objc.scm
~/scheme/eggdoc-svnwiki$ cat output/eggdoc-objc.scm.svnwiki

For batch conversion and addition to svnwiki I did something silly like

cd output
for i in *; do perl -e '$_ = $ARGV[0]; 
  $f = $_; s/eggdoc-//; s/\.scm\.svnwiki//; 
  print "mv $f ~/scheme/chicken-eggs/wiki/$_\n"; 
  print "(cd ~/scheme/chicken-eggs/wiki && svn add $_)\n" ' $i;
done

resulting in script output which you can later direct to a shell:

mv eggdoc-args.scm.svnwiki ~/scheme/chicken-eggs/wiki/args
(cd ~/scheme/chicken-eggs/wiki && svn add args)
mv eggdoc-doctype.scm.svnwiki ~/scheme/chicken-eggs/wiki/doctype
(cd ~/scheme/chicken-eggs/wiki && svn add doctype)
mv eggdoc-eggdoc.scm.svnwiki ~/scheme/chicken-eggs/wiki/eggdoc
(cd ~/scheme/chicken-eggs/wiki && svn add eggdoc)
mv eggdoc-hostinfo.scm.svnwiki ~/scheme/chicken-eggs/wiki/hostinfo
(cd ~/scheme/chicken-eggs/wiki && svn add hostinfo)
mv eggdoc-sxml-tools.scm.svnwiki ~/scheme/chicken-eggs/wiki/sxml-tools
(cd ~/scheme/chicken-eggs/wiki && svn add sxml-tools)

Ugly but effective.
