Wikipedia and its sister sites make heavy use of templates. I want to find the source code behind those templates, i.e. the code that renders the HTML from a given template reference.
Looking here, I found a few files which seem to deal with templates, but I could not find any results when looking for a specific one. For example, the template {es-conj}, which renders a conjugation table for a given Spanish verb, did not show up in the search list.
Turns out, the source code of the template is saved as plain-text in the template's wiki page itself. To see the source code of the template {es-conj}, just go to its page and click Edit:
You can check the templates involved in generating the page via page information, linked from the sidebar on desktop skins (e.g.). There's an edit / view source link for each.
You can also add ?action=raw&templates=expand to the URL of a page to see the page source after all templates have been processed.
