Changing map title

Hello, I'm not too skilled in the coding side of wikipedia, so please bear with me! I'm currently trying to change the title of the map Module:Location map/data/China Tibet topography. Right now, it's showing up in the infobox of articles including Mount Everest as China Tibet topography when all it should say is Tibet. Changing the title value in the code didn't seem to change it. Do I have to move the location map module page? Any help is appreciated. --NoGhost (talk) 20:55, 12 March 2017 (UTC)

NoGhost, I searched Mount Everest for "China Tibet topography" and found nothing. What is the problem exactly? Thanks! Plastikspork _―Œ^(talk) 21:26, 12 March 2017 (UTC)

@Plastikspork: Oh, it seems to be displaying correctly now! I guess it just took awhile to update. Thanks for checking. --NoGhost (talk) 21:57, 12 March 2017 (UTC)

Philadelphia map not big enough?

The coordinates for Watson Comly School are outside the Philadelphia box, and I've double checked that the coordinates are correct and are within Philadelphia. The template uses File:Location Map Philadelphia Metropolitan Area.png, which cuts off at or very near the building's location. I can't quite tell from the map styling. Is this an issue with insufficient border coordinates being set, or should there be a larger map for Philadelphia? (Is this even the right place to ask?) kennethaw88 • talk 07:53, 16 March 2017 (UTC)

kennethaw88, if you look at a larger version of the map image, you will see a purple dashed line. that line is the boundary of Philadelphia. it looks like that when User:Vrysxy exported the image from openstreet map, the image was cropped too much. you could try to export a new image from open street map using a larger region. just make sure you keep track of the bounding box lat/long information. or, try asking at WP:Maps or Graphics Lab/Map workshop to see if someone there can help. I would help, but I haven't had any luck with exporting images from openstreetmap. Frietjes (talk) 15:27, 16 March 2017 (UTC)

Thanks, I asked over at WP:Graphics Lab/Map workshop. kennethaw88 • talk 19:01, 18 March 2017 (UTC)

Template-protected edit request on 23 March 2017

Request to enable the following:

OpenStreetMap Central Pretoria

to be used as a map for locations within the city of Pretoria itself. SpringbokSam (talk) 16:40, 23 March 2017 (UTC)

You can do this yourself. Just create the location map data for it, like I did here: Module:Location map/data/Beijing. You only need the precise latitude and longitude of its edges. Or if you have them but are unsure of creating the module post the coordinates here and someone else can easily do it.--JohnBlackburne^words_deeds 17:00, 23 March 2017 (UTC)

Ah, it contains coordinates. I have created the data at Module:Location map/data/Pretoria. To use it simply do {{Location map|Pretoria}} with appropriate coordinates and other parameters. When you do please double-check the location is right, in case the coordinates are not precise enough for the map.--JohnBlackburne^words_deeds 17:07, 23 March 2017 (UTC)

And I made a couple of mistakes but have hopefully now corrected them. I added the map to Transvaal Museum as a test and it seems to be working, and is certainly more useful than a map of the whole province.--JohnBlackburne^words_deeds 17:17, 23 March 2017 (UTC)

Glitch on the Greenwich date line

Location map/Archive 9 (Ghana)

Location map/Archive 9 (Ghana)

Only one of these maps works; the only difference is using E or W for the longitude. Oddly the coordinates both work fine as standalone coordinates:

• 5°40′0″N 0°0′0″E
• 5°40′0″N 0°0′0″W

Noticed and fixed at Tema. Is likely not going to come up often as there can’t be that many places exactly on the date line, but something odd is happening.--JohnBlackburne^words_deeds 07:01, 6 March 2017 (UTC)

JohnBlackburne, if you inspect the HTML source, you will see that the {{coord}} template is returning 5.66667°N 0.00000°E in the metadata for the first one and 5.66667°N -0.00000°E for the second one. the coord2text code expects the two numbers to be positive. the interesting thing is that there is a second chunk of metadata which has the coordinates with sign separated by a semicolon. I wonder if we should just use that chunk instead of the first chunk. this would help with translating the module to other wikis which have different letter symbols for North/East/South/West. I recently had to do this on the Vietnamese Wiki. Frietjes (talk) 14:15, 6 March 2017 (UTC)

I can see what you mean; Seems to me the problem is with {{coord}}, if it’s outputting plus and minus zero for the same coordinate, especially as there are no negative numbers in the inputs which are valid inputs. But it’s not something I’m confident fixing or proposing a fix as I have no experience with either template, and would be far too wary of breaking anything. This is a particular edge case that’s broken, but fixing it might impact other edge cases.--JohnBlackburne^words_deeds 06:58, 8 March 2017 (UTC)

One more instance of it: Bilanga-Yanga. Fixed, posted for reference.--JohnBlackburne^words_deeds 15:41, 13 March 2017 (UTC)

JohnBlackburne, those poor people who have to live in the middle of a lake! I fixed the imprecise coordinates. thank you! Frietjes (talk) 16:18, 13 March 2017 (UTC)

Ah,.thanks. This one I thought "I’ve seen this before!" and rapidly fixed it checking it only in preview. I did not think to check whether the position made sense.--JohnBlackburne^words_deeds 16:22, 13 March 2017 (UTC)

Maplandia map problem?

And one more: Ganta, Burkina Faso. This was another one which was wrong, though not horribly wrong so it was easy to find and fix. Except oddly I too got it wrong first time as I copied the values from here: Ganta Map — Satellite Images of Ganta which has the minutes as 30'W instead of 3'W, despite locating it correctly on the map. I don’t know if this is a syatemic error with this service, in which case a lot of other locations could be wrong if people are basing them on it.--JohnBlackburne^words_deeds 13:24, 18 March 2017 (UTC)

@JohnBlackburne and Frietjes: Fixed; the issue was that the coord2text regex didn't allow negative numbers. {{coord}} should probably be modified so it outputs 0.0°S/W instead of -0.0°N/E. Jc86035 (talk) Use {{re|Jc86035}}
to reply to me 08:46, 23 April 2017 (UTC)

Thanks. I think I’ve encountered it a couple more times since, but was easy to fix, checking the coords for more precise ones, working round it if zero was correct. I do agree, outputting negative zero makes no sense at all; even if output values ranged over positive and negative numbers, zero is not normally considered negative, outside of some fairly esoteric cases in mathematics.--JohnBlackburne^words_deeds 15:13, 23 April 2017 (UTC)

Icon position error

Moved from Template talk:Coord § Icon position error

 – Jonesey95 (talk) 14:49, 23 April 2017 (UTC)

I noticed that the position of the airplane icon (the "pushpin_mark" graphic) is misleading in the Joint Base Anacostia–Bolling article. It appears at the tip of Greenleaf Point, even though the coordinates for JBAB appear to be correct in the template. Clicking on the Coordinates text in the article as displayed shows the correct location about a mile south of Greenleaf Point. At first I thought this error was related to the fact that the pushpin label wraps across three lines, but reducing the label to one line doesn't solve the problem. So I don't know how to fix the problem, but it seems to be real enough. 76.22.118.146 (talk) 02:00, 23 April 2017 (UTC)

JB Anacostia–Bolling

See the pushpin map at right. Is the aeroplane icon displayed in the correct position here? If it is, there is some sort of problem in extracting coordinate values from {{Coord|38|50|34|N|077|00|58|W|name=JB Anacostia–Bolling|display=inline,title}} but if it is also wrong, the problem is nothing to do with {{coord}} but concerns {{Location map}}, and is most likely to be the corner coordinates that are recorded at Template:Location map USA District of Columbia. The best place to discuss that is at Module talk:Location map. --Redrose64 🌹 (talk) 08:53, 23 April 2017 (UTC)

JB Anacostia–Bolling

Replacing the map name with "Washington, DC" works for some reason, even though the location map in question appears to be a redirect. I must be looking in the wrong place for the map that is used. I don't know if this helps, but the map corner coordinates used at Module:Location map/data/USA District of Columbia and Template:Location map USA District of Columbia do not match. – Jonesey95 (talk) 14:44, 23 April 2017 (UTC)

@Jonesey95: The template should probably be deleted and its bounding box values moved to the module subpage. (The module subpage also seems to have other problems, like a second image which doesn't exist.) Jc86035 (talk) Use {{re|Jc86035}}
to reply to me 15:02, 23 April 2017 (UTC)

Fixed the module. Jc86035 (talk) Use {{re|Jc86035}}
to reply to me 15:09, 23 April 2017 (UTC)

That works for me. Now the two maps match. Why did "Washington, DC" work though? Where is the file or data for that? I see that you also fixed Module:Location map/data/Washington, DC, which was making "Washington, DC" work as a map name.

I fixed a typo in the documentation to make that image appear. – Jonesey95 (talk) 15:17, 23 April 2017 (UTC)

@Jonesey95: I've replaced all the redirects to the template as module subpages as well and CSDed the template. Jc86035 (talk) Use {{re|Jc86035}}

Looks fine now. Thanks to all for your help. 76.22.118.146 (talk) 23:51, 27 April 2017 (UTC)

Selecting maps to show based on coordinates?

I'm trying to incorporate location maps in infoboxes that are entirely using data from Wikidata, such as Template:Infobox telescope. See South Pole Telescope for an example of this in action, where it is working well by using coordinate location (P625) and country (P17). However, in cases like Arecibo Observatory, this does not work so well, since the country is the United States, but File:Usa edcp relief location map.png doesn't include the right part of the US. Even worse is places that are located in Hawaii! I was wondering if there was a way of automatically selecting the map to show based on the coordinate given at all? Alternatively, is there a good matching between the location maps here and a Wikidata property that could be applied here? Thanks. Mike Peel (talk) 22:57, 4 May 2017 (UTC)

For frwiki, we decide to choose to use the coordinates to determine the map. Note that isn't a perfect solution, it always give the United States map for places in southern Ontario or Quebec. --Fralambert (talk) 23:31, 4 May 2017 (UTC)

@Mike Peel: Sooner rather than later we will be able to link to map data on Commons on Wikidata items. I would guess this could be used to select the correct maps. You probably shouldn't use country but instead "is in administrative territory" (though there are a few other possibilities, that one will be the most relevant), which will get you the smallest place in which the 'scope is located. --Izno (talk) 02:44, 5 May 2017 (UTC)

@Izno: What's the barrier with linking map data on Commons to Wikidata items? Can the location map code cope with, e.g., Arecibo (Q640728)? Thanks. Mike Peel (talk) 02:46, 5 May 2017 (UTC)

@Mike Peel: I... don't actually know if I can answer that? Maybe I'm wrong on this point. Maybe drop this question at d:WD:PC for once. --Izno (talk) 02:50, 5 May 2017 (UTC)

@Izno: OK, I've started a discussion at [1]. Thanks. Mike Peel (talk) 03:02, 5 May 2017 (UTC)

Location map error category

I've been fixing errors in the category Category:Location maps with different longitude and latitude precisions. I have cleaned-up all the errors in articles, and a few in Draft/User space too. The category is now empty except for one item, an archived 7-year-old Module talk page. While not causing any "problems", I'd like to get rid of this just to have an empty category, which I will monitor for new errors. Since archives aren't supposed to be edited, and "fixing" the problem there would obscure point of the discussion, is there some technical solution. Can the module be changed to not cause the error report from a talk page perhaps? MB 01:46, 17 May 2017 (UTC)

I have removed the category from the template output on the talk page.[2] I used Special:ExpandTemplates to see the exact code generated, and used {{Replace}} to replace it with nothing. PrimeHunter (talk) 21:57, 17 May 2017 (UTC)

Glitches

• end after if not map then is not needed because we don't want to go further if map does not exist ("Template:Location map" will be found, "Module:Location map/data/" not).
• local moduletitle = mw.title.new('Module:Location map/data/' .. map) and if not moduletitle then error(string.format('%q is not a valid name for a location map definition', map), 2) should be deleted too, because if module with its subpage does not exists that does not mean that we have invalid name for a location map definition.
• A frame must be provided when using a legacy location map should be changed to Type of "frame" must be "table" and type of "frame.expandTemplate" must be "function" when using location map via template "Location map ~". Are location templates really regarded as legacy on en.wiki?
• elseif moduletitle.exists then should be changed to elseif mw.title.new('Module:Location map/data/' .. map).exists then.

PS "What links here" gets links of all modules that don't exist after template is found in second elseif. I've semi-fixed this sr.wiki by reordering module-template check (because templates are used there more than modules, only 12 modules exist). I suppose mw.title.new() is doing this. Is there a way to prevent it?--Obsuser (talk) 13:47, 10 May 2017 (UTC)

Try your changes out in the sandbox and review the test cases for the templates in which that module is used. --Izno (talk) 13:57, 10 May 2017 (UTC)

@Obsuser: Unfortunately, none of these changes are good. Specifically:

• I'd agree about the "end" becoming an "elseif" if not for the intervening code (which was incorrectly removed, as I'll explain below).
• if not moduletitle then doesn't mean "if this module doesn't exist"; it means "if this isn't a valid title at all". Compare these links: https://en.wikipedia.org/wiki/Module:Location_map/data/Some_nonexistent_thing and https://en.wikipedia.org/wiki/Module:Location_map/data/Something_with_an_%5B_in_it
• Regarding the frame error, the checks I'm doing are just to see if the thing is a frame or not. That just makes the error more obscure.
• Changing the exists line causes a Lua error if a bad title (see above) is used.
• Eventually, all map definition templates should be converted to modules, so modules should have priority in the loading order.
• Not being able to find a name makes no sense.

Jackmcbarn (talk) 00:41, 26 May 2017 (UTC)

@Jackmcbarn:

• Why to have end and go further if we don't have map?
• OK.
• No, module checks if type(frame) is not table or if type(frame.expandTemplate) is not function and if one of these is true then flags error. That's why 'A frame must be provided when using a legacy location map' shuld be changed into more descriptive 'Type of "frame" must be "table" and type of "frame.expandTemplate" must be "function" when using location map via template "Location map ~"'. Again, are location templates really regarded as "legacy" on en.wiki?
• OK.
• Then how to stop mw.title.new() from polluting "What links here" special page which gets all modules that don't exist after template is found in second elseif? Currently there is way more templates, so one solution is to reorder check or find other way to check if title is going to be valid (use replace to check if there are any for-title-forbidden characters).
• What was Not being able to find a name makes no sense. related to? --Obsuser (talk) 05:28, 31 May 2017 (UTC)

@Obsuser:

• The error function never returns, so none of the code below it runs anyway. Adding an else would just add another indentation level for no actual gain.
• There's no isFrame() function. If there were, I'd use it instead. type(frame) ~= 'table' or type(frame.expandTemplate) ~= 'function' is just how I make sure that frame is actually a frame. If someone gets that error, they should just pass an actual frame, not add an expandTemplate function of their own to whatever object they're passing.
• Either the template or module "What links here" pages will be polluted. There's no way to avoid that. I chose to pollute the module one, since the goal is to eventually convert all location map templates to modules, which will end the pollution. The template form is regarded as legacy, and in fact, you can't create new map definitions in template form. The only reason there's more templates is that conversion is currently a slow, manual process.
• "Not being able to find a name makes no sense." refers to your sandbox edit that changed the error message "Unable to find the specified location map definition." to "Unable to find the specified location map definition or name."

Jackmcbarn (talk) 21:07, 2 June 2017 (UTC)

@Jackmcbarn:

• We have if not map then error('The name of the location map definition to use must be specified', 2) end and then local moduletitle with .. map and rest; if there is no map, we will not have moduletitle (it will be "Module:Location map/data/" or "Template:Location map "). That's why I don't understand need for running rest of the code, or I miss something...

OK for the rest.--Obsuser (talk) 21:52, 2 June 2017 (UTC)

@Obsuser: The rest of the code already isn't running. Once you call error(), it immediately bails out of the function you're in. Jackmcbarn (talk) 22:37, 3 June 2017 (UTC)

Infobox map

Jackmcbarn, can we merge template:infobox map here? all it does is (1) if the location map exists, then calls location map and (2) if the location map doesn't exist, it assumes that the value in map is an image, and calls the InfoboxImage module. it seems as though if we were able to specify an action for when the map doesn't exist, then we could directly replace template:infobox map with template:location map. for example, something like,

{{Location map|{{{map}}}
| coordinates = {{{coordinates|}}}
| badmaperror = {{#invoke:InfoboxImage | InfoboxImage | image={{{map}}} }}
}}

which is (of course) an abbreviated version of what would actually be put in the transcluding infoboxes. Frietjes (talk) 15:30, 3 June 2017 (UTC)

@Frietjes: I personally don't like that a template with that purpose ever existed (specifically, I think it should be explicit whether you want a map or a static image). Anyway, since I doubt it's going away now, my preferred approach would be to replace it with a nicer Lua wrapper (like /multi is now), rather than to make it part of the main code that every map needs to load. Jackmcbarn (talk) 22:39, 3 June 2017 (UTC)

Jackmcbarn, I totally agree with you that it's a bad design to overload the parameters like that. we can get rid of it, but it will be a process to do so. luckily there are only about 850 pages passing images instead of location maps. but there are about 10 templates which are using it. so we either (a) start discussions on the individual pages, gain consensus, and change the parameter syntax template-by-template, (b) start another TfD for {{infobox map}} and discuss the design flaws there, or (c) start an RfC elsewhere. Frietjes (talk) 13:37, 4 June 2017 (UTC)

@Frietjes: Unless you foresee major objections, my personal opinion would be to WP:BOLDly start fixing articles and individual templates, then if there's an objection, taking it to WP:TFD. Jackmcbarn (talk) 15:54, 7 June 2017 (UTC)

sounds like a good plan. Frietjes (talk) 14:29, 14 June 2017 (UTC)

Allow a static image to be in the list of toggled maps?

Jackmcbarn and others, there is currently an RFC at Middlebury, Connecticut discussing whether or not to include the location map. the primary objection for the location map is that the location map makes the infobox even longer while the static image already shows the location. so, I was thinking that it should be possible to include a static image in the list of toggled maps in this template. so, the static image would be shown first (smallest scale), but one could then toggle to the wider scale location. what do you think? Frietjes (talk) 14:32, 14 June 2017 (UTC)

No objection, although there might need to be a new parameter for the "Show map of the …" image description. Jc86035 (talk) Use {{re|Jc86035}}
to reply to me 15:03, 14 June 2017 (UTC)

It's already possible to do this, although it might not be clear how. I'll set it up on that page. Jackmcbarn (talk) 17:29, 13 July 2017 (UTC)

Okay, having tried it, this module supports the required functionality, but I don't think Template:Infobox settlement does. I set this up in User:Jackmcbarn/sandbox2 without the infobox. I'm not sure what the cleanest way to do this inside an infobox would be. Jackmcbarn (talk) 17:38, 13 July 2017 (UTC)

Coordinates input

@Frietjes and Jackmcbarn: Should |coordinates= allow forms of input which are easier to type and don't involve {{Coord}}, such as the German Wikipedia's d/m/s/[N/S] d/m/s/[E/W] or ±d ±d? This would be useful for e.g. {{Location map many}}. Currently the module only searches for d°m′s″[N/S] d°m′s″[E/W] or d°[N/S] d°[E/W]. Jc86035 (talk) Use {{re|Jc86035}}
to reply to me 09:47, 8 June 2017 (UTC)

Jc86035, I made Module:German coord convert back in 2015 to assist with converting from the German coordinates style. I wouldn't object to having it merged somewhere. if I recall, the reason why slashes are used as delimiters was that back before LUA the only easy way to split strings was to use "titleparts".

Toggle options appear in the wrong place

At Hafenstraße the options to view different maps (of Hamburg, of Germany, or both) appear between the first and second paragraphs of the lede, to the left of the maps. This isn't necessarily confusing or disruptive, but common sense dictates that they ought to appear below the map, and the lede ought to be uninterrupted. I expect the best way to fix this will be to incorporate the map(s) into an infobox, but is this a problem people are aware of, and can it be fixed any other way? – Arms & Hearts (talk) 00:21, 10 August 2017 (UTC)

Jonesey95, On the right, I am seeing where the map should be, just a blue link that says "Location map is located in the Bogota savanna" inside the boxes with the caption properly displayed.

Namespace sort for the tracking categories

@Jackmcbarn and Jc86035: MB made a request on my talk page that we could help with the tracking category cleanup by sorting (or splitting) the tracking categories so that the non-articles were separated from the articles. I have implemented this untested modification in the sandbox to prefix the sort key with a 'μ' for anything that's not in the article namespace. note that the string transformations and namespace detection only happens when there are tracking categories, so the overhead should be minimal. another option would be to have a table with the tracking categories with keys for both main and non-main namespaces, then do a lookup at the end. this could help with localization as well. I just went for the least complicated solution here. comments? Frietjes (talk) 13:37, 4 July 2017 (UTC)

@Frietjes: Two things I'd suggest:

1. Possibly count articles and templates together, since a lot of these problems I see in articles seem to come from a template that contains a location map with an error.
2. Since the sort key already contains useful information, rather than replacing it with a non-useful 'μ', why not use separate categories for articles and non-articles so that that information can be preserved?

Jackmcbarn (talk) 17:25, 13 July 2017 (UTC)

What I was after was segregating things that should be fixed (like articles) from errors that probably shouldn't (like drafts in User sandboxes). So I would agree templates should be fixed as well as errors in other names spaces except User.

I also like the idea of separate categories because that would give a number of errors to be fixed.

Also, the "precision errors" are in a separate sub-cat, but the others are lumped together in the main category which I found highly confusing in the beginning. Can all errors be put in individual categories? MB 18:13, 13 July 2017 (UTC)

@Jackmcbarn and MB: I have modified the sandbox code, so this is now the untested proposed change. splitting the "Page using removed parameter" and "Outside flag not set with mark outside map" into two separate categories would be very easy to do (see this additional change). please feel free to make any further comments, corrections, suggestions (i.e., names for the categories, implementation, etc.). Frietjes (talk) 18:44, 13 July 2017 (UTC)

I note that at least in the documentation, there are two additional possible errors - "Map using removed parameter" and "Name containing pipe".MB 05:56, 14 July 2017 (UTC)

Frietjes, just wondering if you are going to implement this; there hasn't been any update in six weeks or so. MB 01:12, 6 September 2017 (UTC)

MB, I was hoping to hear back from Jackmcbarn about this untested change, which would put 'articles and templates' in a separate category. Frietjes (talk) 13:47, 6 September 2017 (UTC)

@Frietjes: I've been kind of busy lately, so I don't have time to test that myself, but I looked over it, and if it works, I have no objections. (Just remember to create the new category pages, and to link between them and the old ones). Jackmcbarn (talk) 17:36, 9 September 2017 (UTC)

okay, I ended up creating more subcategories and sorting the only non-empty subcategory by "fullpagename", which I believe satisfies the original request. please feel free to adjust it, or point out problems with what I did. Frietjes (talk) 14:52, 14 September 2017 (UTC)

@Frietjes and Jackmcbarn: This last change has been a big help and enables me to easily find articles that contain map errors which should be fixed. There are none right now and I have been quickly catching some cases of vandalism that previously went unnoticed for months. There are still about 150 "outside" errors, mostly in user space. This number fluctuates slightly; unless I remember the last number exactly I still have to scan the entire list to look for new mainspace errors to fix. I believe it would be better to just not have errors that are not in mainspace. (If a template is causing an error, the articles it affects would be flagged - so the check could be simplified to article-space only). I asked PrimeHunter if he was aware of any general practice and he said "Many templates and modules make a namespace check to only add maintenance categories in mainspace. For example, {{Lang}} adds Category:Articles containing unknown ISO 639 language template to articles and nothing to other pages." Can we add such a check here? Can it be done within a Module with little overhead? MB 15:55, 12 November 2017 (UTC)

definitely possible, perhaps we restrict to (1) article and (2) template namespace as suggested above? if we only check the namespace right before adding the tracking categories, then the overhead is only added for the pages being tracked. Frietjes (talk) 15:58, 13 November 2017 (UTC)

I'm not sure anymore that there is a good reason to include Templates. The current category includes about a dozen errors from Template namespace and they are all in unused templates or other subpages - none of which cause mainspace errors. I am assuming that if a template had a map location error, and it was actually transcluded in an article, then that article would be in the category also. Investigation of the error would lead to the template and a template fix would resolve the problem.

Is there is some aspect of testing template changes before they are made live that would make this useful? MB 22:44, 13 November 2017 (UTC)

Multi-map not working on some browsers?

I am having a disagreement with Boeing720 at Talk:Gråen#Maps again over whether the multiple map feature should be used at all because on his system the multiple map radio buttons are not working and all the maps display at once. I am unable to verify that any browser has this problem and have checked Edge, Explorer and Chrome on Windows 10 and Safari, Firefox, Chrome and Opera on macOS. I am not clear what OS or versions of browsers Boeing720 is using. To me, if the feature is here and widely used it should be used on any article where it is helpful. Does anyone know how many browsers might be affected by this? Even if it is a significant portion of browsers that visit Wikipedia, which I seriously doubt, how could this be an argument against using it on any given article when it is widely used? Thanks for input. —DIYeditor (talk) 21:06, 4 January 2018 (UTC)

If anyone has time on their hands and is familiar with the map creating software Ecal saputra has uploaded a couple of images for maps, File:Location map Jakarta Metropilitan Area.png and File:Location map Jabodetabek.png, but the coordinates on their description pages are wrong. I only discovered this when trying to create location map data for the first one, and the second one has the same problem. If someone corrects the coordinates for each then it will be easy to create the Location map data for Jabodetabek, and repair the data for Jakarta Metropilitan Area.--JohnBlackburne^words_deeds 17:26, 24 January 2018 (UTC)

@Ecal saputra and JohnBlackburne: I created Module:Location map/data/Indonesia Jabodetabek after some experimentation with Open Street Map to visually match the borders of the image. better would probably be to reexport the images while keeping track of the edge coordinates. I also corrected the edges in Module:Location map/data/Jakarta Metropolitan Area. Frietjes (talk) 17:40, 24 January 2018 (UTC)

@Ecal saputra: the best way to track edge coordinates, I find, is the URL of OpenStreetMap. So, I assume you used the "Share" button. Firstly, Wikipedia generally does SVG, as they scale better. But, when you press that button, it takes you to a page like [3] (you may need to "Copy link address" on your downloads). In that url you have your edge coordinates - bbox=-1.2672472000122073,51.75764705243149,-1.2530851364135744,51.76374974924039.

Multi-map captions?

Hi, recently been working on the Template:Infobox UK place. I worked out the syntax for multi-maps, and applied it to St Anne's College, Oxford, by adding a location_map2 to Template:Infobox residential college. I noticed that there was no way within {{Location map}} to specify captions for multiple maps - I suggest using the # separator as in the {{{1}}} parameter. ∰Bellezzasolo✡ Discuss 23:07, 14 January 2018 (UTC)

I have implemented my changes in the sandbox. ∰Bellezzasolo✡ Discuss 23:57, 14 January 2018 (UTC)

Made an edit request.

Changes:

• caption is now parsed for a # sign, as the Location Map is. This will then provide the different captions for the different maps.
• Any caption with a # is added to the tracking category of possible errors, to allow easy correction of existing pages.

Question: has this change been fully tested? — Martin (MSGJ · talk) 09:19, 16 January 2018 (UTC)

@MSGJ: somewhat, of course I can only edit the sandbox, and this module doesn’t have a good set of testcases. Obviously, if I was editing the live module, I’d be able to preview multiple pages with this change. However, it shouldn’t have any effect except on captions with a #. I added a tracking category, but would a different delimiter be better, such as #$#? My regex knowledge is rather limited. ∰Bellezzasolo✡ Discuss 10:15, 16 January 2018 (UTC)

Bellezzasolo, I like this idea. how about if we start by (1) adding tracking for all captions with a "#", then (2) inspect any that show up in the tracking category, (3) code to make sure we don't break anything. my concern is that if there are URLs or section links in the caption, then a "#" in a URL or a section link might break things. if we find any of these, we can make sure we don't break these with the new syntax. however, if this is not actually happening in practice, then we can use less complicated regular expressions. Frietjes (talk) 15:48, 16 January 2018 (UTC)

@Frietjes: Yeah, after I proposed the # (because of uniformity with {{{1}}}) I realized how frequently used the # might be. I'd definitely go for tracking category first, and perhaps change to a single character that is very unlikely to be used, like ⨌ ? ∰Bellezzasolo✡ Discuss 15:54, 16 January 2018 (UTC)

Bellezzasolo, okay, I have added "Category:Pages using location map with a number sign in the caption" and temporarily disabled the "edit request". it will take some time for the category to fill up (if there as anything that should be in there). once it's done filling, we can decide what to do next.

That's pretty silly syntax, makes errors really easy to make. ∰Bellezzasolo✡ Discuss 17:04, 16 January 2018 (UTC)

Frietjes Looks to me like the contents of the category are using the '#' symbol for colour codes. It also looks like a manageable category, although I don't know how long it will take for everything to filter through. ∰Bellezzasolo✡ Discuss 21:33, 18 January 2018 (UTC)

Bellezzasolo, yes, so far the tracking is matching (a) colours, (b) section links, (c) unicode ndash entities using &#8211; (which I have been fixing) and (d) {{sp}} (used as a hack to add an empty caption which I have been fixing). at a minimum, we should probably expect (a) and (b) to be valid inputs. so, we can either code around those cases or select a different delimiter. it would be best if the delimiter were something on a standard keyboard, but not something that is going to have false positives. if there is nothing suitable on a standard keyboard, another option would be to have an axillary template that takes the captions as input, and outputs the captions with the delimiters inserted. but, in my opinion, that's not the best option. Frietjes (talk) 21:41, 18 January 2018 (UTC)

Frietjes I actually like the auxiliary template idea, and there are several approaches (of course, they would mean another template). However, if we went with a delimiter of ⨌ (I'm pretty sure would get no hits), we could do a template like {{Location map separator}} for people. However, I do think that a template that took a list would be cleaner syntax. Copy/paste isn't too hard, but that way we have an ASCII option. Of course, something on the standard keyboard is ideal, but the options are very limited. ∰Bellezzasolo✡ Discuss 21:48, 18 January 2018 (UTC)

Bellezzasolo, another option would be to use ## or <#> or something with more than one character. Frietjes (talk) 21:51, 18 January 2018 (UTC)

Yeah, that's pretty ideal (originally, I was thinking ## to generate a # rather than a separator, a la printf()). You'd have to do the regex for that one though! ∰Bellezzasolo✡ Discuss 21:53, 18 January 2018 (UTC)

((?!##).(?<!##))+

Seems right ∰Bellezzasolo✡ Discuss 21:59, 18 January 2018 (UTC)

@Frietjes:

local newstr = string.gsub(args['caption'], '##', '⨌')
for caption in string.gmatch(newstr, '[^⨌]+') do

as on the sandbox seems to be the ticket. ∰Bellezzasolo✡ Discuss 22:40, 18 January 2018 (UTC)

Bellezzasolo, I would think that you could do this in one step with mw.text.split(args['caption'], '##', true )? Frietjes (talk) 22:46, 18 January 2018 (UTC)

Frietjes yeah, that works. I used gsplit to get an iterator. ∰Bellezzasolo✡ Discuss 23:33, 18 January 2018 (UTC)

I don't see it either, but in a case like this, I usually try to break down the article into smaller pieces to see which piece(s) trigger the error. So take half of the article and put it in a user sandbox, then take the other half and put it in a different user sandbox. Whichever half has the error, keep dividing that text in half until you have isolated the code with the error. It usually works. – Jonesey95 (talk) 19:20, 20 February 2018 (UTC)

Updating the code of Location map's p.mark method with this change. This allows the support of multiple maps by the method. This is complemented by this change to Location map/multi's p.container method (also copying the switcherHelper from location map).

• Support multiple maps with the same set of multiple marks (see Template:Location map+/testcases). This could be useful for places, like the University of Oxford, with many places in a small area, with a few spread out places.
• Support multiple map captions for multimaps.

• Regarding implementation, how it works is {{Location map+}} calls Module:Location map/multi's p.container method. This method handles creating the map, and also puts the multiple marks onto the map, which are passed as a parameter of multiple {{Location map~}} instances. This template calls Module:Location map's p.mark method to place the mark. That's the current system. I changed /multi to produce the switcher maps (this is done with a Javascript gadget internally), which are currently used by Location map (e.g. in the infobox at Cambridge, Massachusetts). Of course, the mark positions vary depending on the map and the scale. p.mark translates the geographical position of the location into a page position (I believe much like {{Overlay}}, but I didn't need to touch this code). As a result, I changed p.mark to parse the {{{1}}} parameter much like p.main (same module). This is the same parsing performed by my change to /multi as well, and is consistent with the current consensus. What is done in my version is that a set of (page) coordinates is produced for each map by the p.mark call. This then produces a list of positions, all separated by the string #PlaceList#. It looks like this: (Place1Map1, Place1Map2, ..., Place1MapN, Place2Map1, ..., PlaceMMapN). I then essentially transpose this matrix (in list form) to get a list of the places for each map. The resulting lists are fed to the respective maps, and the result is concatenated into the final, switching, map set. Of course, this procedure would go wrong if the editor put the wrong number of maps into one of the {{Location map~}} instances, however this is, I believe, a matter of WP:CIR, and should be fairly obvious in most cases. It is an unfortunate limitation of the current system, that the parameter has to be duplicated like that. As a final change, I added support for multi-map captions as per the above edit.  ∰Bellezzasolo✡ Discuss 21:48, 19 February 2018 (UTC)
