About REVISIONUSER
{{REVISIONUSER}} is a "magic word" that returns the last person to change an article. On November 14, 2013, this feature was expanded to include {{REVISIONUSER:(article-name)}}, which makes it possible to query who edited any of a number of other articles. This template does not need to be used in place of the magic word normally, but is provided so that a WP:Lua module can use frame:expandTemplate to access this function. (There may well be some other better way to do this).
Example:
- Straight from the parser function by typing
{{REVISIONUSER:Astronomy}}→ Cosmia Nebula (i.e. User:Cosmia Nebula) - Through this wrapper template
{{REVISIONUSER|Astronomy}}→ Cosmia Nebula
Limitations
Note: Use of REVISIONUSER with a parameter appears to be counted as an expensive parser function against the page limit. This can be confirmed using Module:Preview expense.
There is a Bug in the {{REVISIONUSER}} magic word (tracked in Phabricator as Task T166946) which prevents it from working properly if the user name starts with certain wiki-markup characters such as a * and possible other characters. The work-around is to wrap the call to the magic word with the nowiki function of Module:String2:
- For this page:
{{#invoke:String2|nowiki|{{REVISIONUSER}}}}→ Vaulter - For User:***SkooterBecca***:
{{#invoke:String2|nowiki|{{REVISIONUSER:User:***SkooterBecca***}}}}→ ***SkooterBecca*** - or
{{#invoke:String2|nowiki|{{REVISIONUSER|User:***SkooterBecca***}}}}→ ***SkooterBecca***
For consistency with the magic word, this template does not make that adjustment. The assumption is that if you are using frame:expandTemplate you also have the ability to implement code similar to the nowiki function of Module:String2.
