Modifying IkiWiki

(Blog software announcement 2019-2)

It's incredible how flexible IkiWiki is.

For changing the page output, you can create a templates directory and copy your ikiwiki installation's page.tmpl to there - that's it! This will override the template and you can start making changes to it. (That's how I got the additional CTIME/MTIME lines added, where most of the time only one of them was provided so it felt for me as if information was missing when looking only at a single page...)

For changing code (at least as long as it's part of a plugin), you can set a libdir in the config, set up the required subdirectories IkiWiki/Plugin, copy your ikiwiki installation's comments.pm to there - and it'll override the installed plugin, so you can start to make live code changes.
