[pmwiki-users] [PATCH] create links to individual changes on history page

[Johannes Winkelmann]

Hi,

For a setup of ours, we wanted to link directly to particular wiki
changes from the history. To achieve this, I've introduced a link anchor
using the timestamp of a change, allowing to link via
  ?action=diff#<timestamp>

I also added a small link (using a hashmark as link text) to allow
copying a link to a particular change on the history view, i.e. for
e-mail exchange/discussion. An example of how this looks like can be
found here:
 http://www.ife.ee.ethz.ch/qbic/wiki/Main/QBICBuildroot?action=diff
direct link to a change:
 http://www.ife.ee.ethz.ch/qbic/wiki/Main/QBICBuildroot?action=diff#1154934947

I also exported a new variable $CurrentTimestamp similar to
$CurrentTime, allowing to change the formatting on the RecentChanges
pages to something like:

  $RecentChangesFmt['$Group.RecentChanges'] = 
    '* [[$Group/$Name]] ([[$FullName?action=diff#$CurrentTimeTimestamp|diff]])  . . .  $CurrentTime $[by] $AuthorLink: [=$ChangeSummary=]'; 

which will display a '(diff)' link next to each change, linking directly
to a particular change. Again you can find an example here:
  http://www.ife.ee.ethz.ch/qbic/wiki/Main/RecentChanges


Finally, the patch is at 
  http://jw.tks6.net/files/pmwiki-history-anchors-and-links.diff
with an alternate version omitting the anchor link text at
  http://jw.tks6.net/files/pmwiki-history-anchors.diff
Note that the patches include a description text, so the real changes
affect three lines of code only :-).


I'm not sure if this is interesting for others or even inclusion into
pmwiki, but it's been quite helpful for us and I'd appreciate to get
some feedback here.

Regards, Johannes
