Unexpected effects

I found this, not sure if it has to do with TemplateStyles etc. Article Great Western Railway uses {{Infobox GWR}}, {{Track gauge}} and {{Convert}}.

It has template output like:

{{Track gauge|uksg}} (in lede)

expct: 4 ft 81⁄2 in (1,435 mm)

shows: 4 ft 8+½ in (1,435 mm)

{{Convert|11+1/2|mi|km|0|adj=on}} section (in body)

expct: 111⁄2-mile (19 km) section

shows: 11+½-mile (19 km) section

That is: the "+" and "½" (fraction character) are unexpected. This also happens within {{Infobox GWR}}.

Research & reproduce: I found that when {{Infobox GWR}} is removed (absent), the output is regular. To reproduce: in Special:ExpandTemplates put the lede (and the {{Convert}} code from body), and check with/without {{Infobox GWR}}.

This is as far as I could get. Has to do with TS? @Izno: -DePiep (talk) 09:52, 17 May 2021 (UTC)[reply]

This is due to the specific template first using this module when the module is wrapping the gauge in a link and is fundamentally this issue. Let me see if I can fix it here. Izno (talk) 15:10, 17 May 2021 (UTC)[reply]

The issue is in formatImp. I think I can do a limited fix though I hate that I must do it the way in question. Let me tweak the sandbox. Izno (talk) 15:17, 17 May 2021 (UTC)[reply]

First fix works. I will see if I like one of the other solutions I was thinking about. Izno (talk) 15:32, 17 May 2021 (UTC)[reply]

I think I do prefer this version. Please feel free to sync as desired. Izno (talk) 15:49, 17 May 2021 (UTC)[reply]

Test #1. Basic input options look fine, using Module:Track gauge/sandbox: see Template:Track_gauge/testcases#All

. -DePiep (talk) 21:23, 17 May 2021 (UTC)[reply]

Test #2: Article Great Western Railway with {{Track gauge/sandbox}}, also in {{Infobox GWR/sandbox}}. OK in preview.

. -DePiep (talk) 21:38, 17 May 2021 (UTC)[reply]

OK. Edit request: Please someone put all code Module:Track gauge/sandbox into Module:Track gauge (diff). -DePiep (talk) 21:38, 17 May 2021 (UTC)[reply]

Recurring bug

@DePiep: I'm still seeing the + (but not the fraction character) at Track gauge#Early track gauges ("the Dundee and Newtyle Railway (1831) in the north-east of Scotland adopted 4 ft 6+1⁄2 in (1,384 mm)"). The correct output appears in preview. Hairy Dude (talk) 12:48, 24 August 2021 (UTC)[reply]

@Hairy Dude:. OK here. Did you try to Purge the article (=click on clock topright on the page)? (Could be you have an old version in the cache). Anyway, I have made a minor edit, so the article should reload anyway. OK now? -DePiep (talk) 12:55, 24 August 2021 (UTC)[reply]

That was the first thing I tried after I saw the preview was correct. And I also made a minor edit to check. Are you not seeing it? Maybe it's some quirk of the mobile interface. Hairy Dude (talk) 13:04, 24 August 2021 (UTC)[reply]

ah, mobile. Yes wrong on my mobile device too. Don't know from here. -DePiep (talk) 18:47, 24 August 2021 (UTC)[reply]

Izno, could you take a look?

In mobile view, Track gauge#Early track gauges using {{Track gauge|4ft6.5in}} shows the "+"-sign in a fraction. -DePiep (talk) 11:02, 11 September 2021 (UTC)[reply]

This change should work around it. Izno (talk) 13:22, 11 September 2021 (UTC)[reply]

Coming back two years later, I'm still seeing these pluses at Track gauge. Hairy Dude (talk) 13:00, 21 August 2023 (UTC)[reply]

And another year and a half: it's still happening, on the desktop version of Beer Heights Light Railway. @Izno's work-around fixes it. Bazza 7 (talk) 11:38, 10 February 2025 (UTC)[reply]

@Bazza 7 it should not be necessary there. Infoboxes are not impacted by this issue. And actually, sidebars should not be impacted by this issue these days either, as they have special code that goes and finds the relevant tags. Izno (talk) 21:45, 10 February 2025 (UTC)[reply]

The actual issue is that you (general) put {{RailGauge}} inside a link, which is due to a different interaction with the parsing software, see phab:T200704. If you want to link a rail gauge, please use the appropriate option |lk=on. Izno (talk) 21:48, 10 February 2025 (UTC)[reply]

@Izno: Thanks for the explanation. I didn't code that part of the article but came across it in passing. The error appeared in the main article text as well as the info box, which is what made me think the fault still existed. Thanks for correcting the article.
