Editing Template talk:If empty (section)

== Error transclusion issue with the new Lua version ==
Since [[Module:If empty]] went live, all uses of {{tl|Infobox mountain}} are transcluding errors. There is just one {{tl|error}} check in this template, to ensure that the parameter '''name''' is given. I verified with {{tl|Infobox mountain/sandbox}} that the old template did not transclude  false errors unless the name truly was not given.

:{{ping|Codehydro|Jackmcbarn}} any comments? Can either of you fix this? I'm not following what you mean by "fragile, convoluted, hacky way to do it". Thanks, [[User:Wbm1058|Wbm1058]] ([[User talk:Wbm1058|talk]]) 22:47, 26 December 2014 (UTC)
:* Please describe how you found this error and what exactly is wrong. I do not see any problems on any of the pages that use {{t|Infobox mountain}}  —[[User:Codehydro|<span style="color:#aaaaaa;font-family:Unicode;font-size:12pt;">'''Code'''</span>]][[User talk:Codehydro|<span style="color:#5577aa;">'''Hydro'''</span>]] 23:48, 26 December 2014 (UTC)
:**Look at the pages transcluding {{tl|error}}s in [//en.wikipedia.org/w/index.php?title=Special%3AWhatLinksHere&target=Template%3AError&namespace=0 main namespace]. Most are mountain articles such as [[Mount Kilimanjaro]], which transclude {{tl|Infobox mountain}}. There are no actual errors in these articles, and that's why I call these "false transclusions".  {{tl|error}} should only be transcluded in these articles when the name is missing and the error message "Mountain name required" is shown at the top of the infobox. This is how I patrol for these, by looking for {{tl|error}} transclusions. [[User:Wbm1058|Wbm1058]] ([[User talk:Wbm1058|talk]]) 00:04, 27 December 2014 (UTC)

:*** Thanks for pointing this out. I've rewritten the error check at {{t|Infobox mountain}}'s sandbox as not to use this module at all. While using {{t|If empty}} to produce a transclusion is clever, it's not at all a common use (based on the relatively tiny number of transclusions of {{t|error}} in template space). The purpose of this module is to check multiple variables... even though this module is much less expensive than the old wikitext template, it is more expensive than a simple #if call, which is what should be used to check a single empty param. While I have an idea how to make the module avoid false transfusions, I do not want to encourage this usage.  —[[User:Codehydro|<span style="color:#aaaaaa;font-family:Unicode;font-size:12pt;">'''Code'''</span>]][[User talk:Codehydro|<span style="color:#5577aa;">'''Hydro'''</span>]] 04:50, 27 December 2014 (UTC)
:****Thanks, {{U|Codehydro}}. Now I see that similar changes are needed for {{tl|Infobox mountain pass}}, {{tl|Infobox cave}} and {{tl|Infobox landform}}. I'm willing to make these fixes myself, but thought I'd offer them to you as an opportunity to build up your template-edit-request track record, if you would like to do that.

:**** Thanks. I've applied the change to each of those templates. None are protected so doesn't really help me get template editor at all since I've no shortage of non-protected edits, but the thoughtfulness is appreciated.  —[[User:Codehydro|<span style="color:#aaaaaa;font-family:Unicode;font-size:12pt;">'''Code'''</span>]][[User talk:Codehydro|<span style="color:#5577aa;">'''Hydro'''</span>]] 15:17, 27 December 2014 (UTC)
:****: Great. One more: {{tl|Infobox climbing area}}. [[User:Wbm1058|Wbm1058]] ([[User talk:Wbm1058|talk]]) 15:50, 27 December 2014 (UTC)
:****::{{ping|Wbm1058|Codehydro}} This is actually a bug in Module:Arguments. Once I get it fixed, this won't be a problem anymore. You don't need to "fix" any more templates that use this, as they'll all be fixed again soon. [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 05:00, 28 December 2014 (UTC)
