This plugin, which can be downloaded
|
|
[here](http://www.jk.fr.eu.org/ikiwiki/showdiff.pm),
|
|
adds a "Show Diff" button to the page edition template.
|
|
When clicked, a diff between the stored page and provided content
|
|
is shown in the "Page Preview" area.
|
|
|
|
It depends on
|
|
[this patch](http://www.jk.fr.eu.org/ikiwiki/pluggable_editpage_buttons.diff),
|
|
which does the following:
|
|
|
|
* add a title to the editpage form;
|
|
* pass a reference to the list of buttons to the formbuilder_setup
|
|
hooks, so we can add ours;
|
|
* relax asumption about the possible submit values (use "Save Page"
|
|
explicitly);
|
|
* de-hardcode the submit buttons from the editpage template
|
|
(was this intended to work around something?).
|
|
|
|
> That was there to work around a bug in CGI::FormBuilder 3.0401
|
|
> that broke FORM-SUBMIT on customised templates. That seems to be
|
|
> fixed in the newer version ikiwiki already depends on. Patch accepted.

## Problems
|
|
|
|
No special handling is done of concurrent edits: changes introduced
|
|
independently will show up in the requested diff, although they will
|
|
be merged when the page is saved. I suspect even detecting this case
|
|
would require changes in the RCS backends.
