There is currently a code mistake in Module:String.replace(): if provided with plain = '' (argument present, empty string), the "plain mode" is unexpectedly set to "false", instead of the default "true".
To better understand the issue, see this diff: 1123206365.
The template {{Replace}} is consequently affected: if doing {{replace|...|plain=}}, the "plain mode" is also unexpectedly set to "false", instead of the default "true".
Therefore, I am suggesting the following code, that replaces {{{plain|true}}} with {{{#if:{{{plain|}}}|{{{plain}}}|true}}. In addition to being better practice, it will "detach" the template behavior from the module behavior, so that the template works as expected (i.e. empty parameter gives default mode "true"), whether the module remains as currently, or gets fixed in the future.
<includeonly>{{safesubst:#invoke:String|replace|source={{{1}}}|{{{2}}}|{{{3}}}|plain={{safesubst:#if:{{{plain|}}}|{{{plain}}}|true}}|count={{{count|}}}}}</includeonly><noinclude>
{{documentation}}
</noinclude>
I have checked in the whole wiki, and there is no {{replace|...|plain=}} use currently. So the change is completely safe.
Finally, note that if the module is fixed in the future, it would be possible to simplify the template code to |plain={{{plain|}}}.

- I have just noticed that
Module:String.find()is affected by the exact same issue. And I have already noticed a consequently affected template: {{If string}} (which is very rarely used), and another one: {{In string}}. These templates currently useString.find()by default in "plain = false" mode (because of the module bug), and fixing the module would change the default mode of these templates to "true" if they are not modified adequately. - By "detaching" behaviors (as in the current edit request) and leveraging the powerful in-wiki search engine (that allows regex searching) to examinate the existing uses, fixing all of that is quite simple actually.
- (edit: just noticed that
Module:String.count()({{string count}}, {{str count}}…) is affected by the same issue) - Od1n (talk) 08:45, 19 August 2024 (UTC)

- Thanks. A few other edit requests should be following up, to fix the situation step by step.
- As a reminder, the "plain mode" may also be specified as an unnamed parameter. Fortuitously, it is very unlikely that someone has specified a "plain mode" as a both unnamed and empty parameter. However, when fixing the module, we should consider that the parameter value may have spaces.
