== Issues with national party seats in national legislatures ==

Hey @[[User:Trappist the monk|Trappist the monk]], how are you? I am working on the translation of the module to use it across various Wikis, wanna help? I think key will be to find a way to localise the calls to Wikidata.

But a lower-hanging fruit is the case of Portugal, where the calls to wikidata and the composition bar are quite compatible with the English version. As you can see [[:pt:Módulo Discussão:European and national party data/Exemplos para testes|here]] and [[:pt:Módulo Discussão:European and national party data/Exemplos para testes composition bar|here]], most tests work. The ones that don't seem to only concern the number of seats of national parties (called with their qIDs in the tests) in national legislatures, which would concern the function <code>npp_seats_and_seat_share_in_national_institutions</code>. However, I am not quite seeing what could be breaking it. Any ideas? [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 08:57, 24 April 2025 (UTC)

:Ok, I am thinking that the member state name may be translated. I am going to try and move from using the member state's name to its qID. [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 09:13, 24 April 2025 (UTC)
::Yes, that was it and I added european_party_qid and member_state_qid to the online table, in order to run checks on qIDs instead of on names. [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 13:06, 24 April 2025 (UTC)
:A quick look at [[:de:Modul:Wikidata]], [[:es:Módulo:Wikidata]], [[:fr:Module:Wikidata]], [[:it:Modulo:Wikidata]], [[:nl:Module:Wikidata]], [[:pt:Módulo:Wikidata]] seems to show that while there may be similarities among them, they do not appear to be the same as [[en:Module:Wikidata]].  I suspect that the politics necessary to unify these modules would be a daunting task.  Perhaps the better solution is to roll-your-own access to wikidata using the mw.wikibase library.  Such documentation as there is for that is at https://doc.wikimedia.org/Wikibase/master/php/docs_topics_lua.html.
:
:Similarly, you might also create a custom lua version of {{tlx|composition bar}} so that you avoid anomalous variations that might crop up at the various wiki language editions.

::Thanks @[[User:Trappist the monk|Trappist the monk]], I can look into that, but that seems daunting too. I was kind of hoping that with a nice if conditionality on the language, we could spread the arguments as needed based on per-Wiki structures. But I will check your link.
::The composition bar point is probably less feasible, since this template would most likely be sitting next to other composition bars and would therefore really need to look the exact same. [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 11:31, 25 April 2025 (UTC)

== Preventing error message inside composition bar ==

Hi @[[User:Trappist the monk|Trappist the monk]], I have made some good progress on the translation of arguments and parameters, and that should pretty much be ready. Doesn't solve the wikidata/composition bar template implementation issue just yet, but at least I can test deploy to Portuguese Wikipedia (which so far seems to work, see [[:pt:Módulo Discussão:European and national party data/sandbox/testcases composition bar|testcases composition bar]]). 

One separate issue that I have is as follows (in the [[Module:European and national party data/sandbox|sandbox]]): when I ask for the number of seats of a party where Wikidata does not have that information, the function returns an error message, as it should. For instance (note: maybe no longer the best error message, but that's a separate issue): 
 * <code><nowiki>{{#invoke:European and national party data|main|national_party|seats|Q173152|ep}}</nowiki></code> -> <code>{{#invoke:European and national party data|main|national_party|seats|Q173152|ep}}</code>
However, when I call the same function to retrieve that number ''for the purpose of a composition bar'', then I should not have that error message returned, and instead just have the composition bar function itself return an error. I have tried to make this work, but no to avail. Any ideas?
* <code><nowiki>{{#invoke:European and national party data/sandbox|main|national_party|seat composition bar|Q173152|ep}}</nowiki></code> -> {{#invoke:European and national party data/sandbox|main|national_party|seat composition bar|Q173152|ep}}
[[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 12:47, 29 April 2025 (UTC)
:You can have the code that returns the error messages from allpp_seats_in_eu_institutions() return a second value (a boolean) so, at [[Special:Permalink/1287785738#L-457|line 457]] this ([[Special:Permalink/1287785738#L-459|line 459]] similar):

:Then, change [[Special:Permalink/1287785738#L-740|line 740]] to this:
::<syntaxhighlight lang="lua">local has_error;
party_seats, has_error = allpp_seats_in_eu_institutions (frame, party, institution, cfg.body_prop_t[institution]);

	return party_seats;												-- <party_seats> has an error message

== Translation of calls to wd/wikidata and composition_bar templates ==

Hi @[[User:Trappist the monk|Trappist the monk]], so the translation of parameters and arguments now works, and I am just getting to the translation of the calls to wd/wikidata and composition_bar templates. I wrote a xlate_wikidata function in the [[Module:European and national party data/sandbox|sandbox]] and will test it early next week. Would you mind having a quick look to see whether this at least has the possibility of working? That would be helpful. Thanks a lot! Note: the idea is to develop the function in the English wikipedia, to make sure that it does not break anything with the current module, and then to move it to the French Wikipedia to work on adding another language. [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 14:31, 2 May 2025 (UTC)
:At [[Special:Permalink/1288420601#L-145|line 145]], you create <code>args_t</code>.  Are you saying that {{tlx|wikidata}} takes a lua sequence as its options positional parameter?  Are you sure about that?
:
:Is it your intention to duplicate [[Special:Permalink/1288420601#L-146--L-160|lines 146–160]] for each language?
:
:At [[Special:Permalink/1288420601#L-144|line 144]], you fetch the local wiki's language tag.  That happens 9 other times in the module.  Perhaps the best way to do that is to do it only once as an export from the ~/config module.   [[Special:Permalink/1288420601#L-146|line 146]] then becomes:
::<syntaxhighlight lang="lua" inline="1">	if 'en' == cfg.this_project_language then</syntaxhighlight>
:and line 144 goes away.  The other calls to set <code>this_project_language</code> also go away.

::Hey, thanks for the reply! Let me try and address your points in order. 1/ Maybe not, you are right. I was hoping that returning args_t would be akin to return the options one after the other. 2/ Yes, duplicating the lines for each language was kind of my plan. I realise that if we went for an own implementation of the call to Wikidata, as you suggested, we would not need that, but I have no real idea of how to do that (and I still think that wouldn't really work in the case of the composition_bar template, which would still need to look like what the template looks like in each local version). 3/ That's a really good point, I will give that a try. [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 20:55, 2 May 2025 (UTC)
::Hey @[[User:Trappist the monk|Trappist the monk]], I implemented the changes you suggested and went ahead with replacing the use of "frame:expandTemplate" with calls to the new "xlate_wikidata" function, and it just "kinda" works. If you check the regular [[Module talk:European and national party data/sandbox/testcases|testcases]] (not the ones for the composition bar yet), some values work, but some are off. I am having the feeling that the xlate_wikidata function returns the first preferred value for the right entity/property, regardless of the qualifier, which is odd. For instance:
::* <code><nowiki>{{#invoke:European and national party data/sandbox|main|european_entity|seats|EPP|EC}}</nowiki></code> returns 11, which is right, but it is also the first preferred value for seats [https://www.wikidata.org/wiki/Q208242 here];
::* <code><nowiki>{{#invoke:European and national party data/sandbox|main|european_entity|seats|PES|EP}}</nowiki></code> returns 4, which is false, but it is the first preferred value [https://www.wikidata.org/wiki/Q220945 here], under a different qualifier;
::* same thing when asking about [https://www.wikidata.org/wiki/Q25079 ALDE] and the [https://www.wikidata.org/wiki/Q639383 EFA] returning 5 and 8, respectively. 
::This is surprising because these are rather straightforward calls. Any ideas? [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 07:33, 6 May 2025 (UTC)

::::* In <code>xlate_wikidata</code>, we do a check to see whether <code>value_of_qualifier</code> is <code>nil</code> or not. However, even when it is <code>nil</code> (as, for instance, it is in the <code>test2</code> function), it still seem considered as <code>not nil</code> (like if you change the return value in the <code>if nil ~= value_of_qualifier</code> case, this is what will be returned by <code>test2</code>).

== Own implementation  ==

Hey @[[User:Trappist the monk|Trappist the monk]], I just finished rolling out the French version, and am starting the Italian one, so things are moving forward. Say, in a previous question, you had opined that, since templates were different from wiki to wiki, maybe the better solution would be to roll-our-own access to wikidata using the mw.wikibase library.

While I continue to think that this should not apply to the composition_bar templates (so that we keep wikis' respective look and feel) and that doing this for the wikidata templates is above my competencies, I do agree that this would make things easier in the longer run -- for instance, the different implementation in fr-wiki means that several options (reference, width, bar-color, etc.) are not available, which is unfortunate. So I was wondering: is this something that you might consider doing? I would be really useful help! [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 15:12, 13 May 2025 (UTC)
:Yep, I did, but I think that I meant that suggestion as something for {{em|you}} to do; I don't think that I was volunteering to do it.  I don't know much about wikidata and, for me, wikidata isn't all that interesting because it isn't used in my normal areas of interest (with the exception of {{tlx|cite q}} which I will tweak when I have to but otherwise prefer to ignore).

::Ahah, don't worry, I did understand that that was a suggestion for me to do -- I was just wondering whether you actually might consider making an exception and volunteerting in the end.

:Thanks a lot for your help, @[[User:Ahecht|Ahecht]], this is really appreciated. From what I see, your change greatly simplifies the code of the <code>xlate_wikidata</code> function.

:With your solution, can we make [[Module:European and national party data/Wd]] available to other wikis as well? Because of course, as things stand, the module is broken when used in other languages -- see [[:pt:Módulo Discussão:European and national party data/sandbox/testcases composition bar|here]] for example.

== New translation system ==

Hi @[[User:Ahecht|Ahecht]], thanks again for the help; I am just getting to this now. Following @[[User:Trappist the monk|Trappist the monk]]'s message above, I created "/Wd" modules across all relevant wikis. Once that was done, I got an error saying that a "/Wd/i18n" module was also needed, which I understand is for translation. So I went ahead and created those in all relevant wikis (and I will have to localise them).

Now the testcases for en-wiki are working. However, when I try the [[:pt:Módulo:European and national party data/sandbox/testcases|pt-wiki testcases]], for instance, i am told "module 'Module:European_and_national_party_data/Wd/i18n' not found", which is somewhat normal since a module in Portuguese is called "modúlo".

However, it would seem, from the code of the [[:pt:Módulo:European and national party data/Wd|/Wd module]] that "/i18n" is just slapped at the end of whatever the current module is called (in the <code>loadI18n</code> function), which should get the Portuguese name, shouldn't it?

Finally, I note that, in the testcases, line 6 says that it does not recognise the local version of "lower house" ("camara baixa"), which seems to indicate that the translated version doesn't get picked in the /config file; is that what is happening?

Thanks a lot in advance for your help as I get my bearings on the new system :) [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 07:51, 26 May 2025 (UTC)

== Individual members date ==

Hi @[[User:Trappist the monk|Trappist the monk]] @[[User:Ahecht|Ahecht]], very small issue: I think the call to get the "individual members date" no longer works since the move to the own implementation of the calls to Wikidata. I made a test [[User:Julius Schwarz/sandbox|here]] and it is not showing up, neither is it showing up on pages such as [[European People's Party|here]], while I think it did. Any idea why? It's defined around line 324 in the [[Module:European and national party data/sandbox|module]].

Actually, I was trying to find a way to only return the year (by adding something like "individual members year"; how would one do that? [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 21:14, 29 May 2025 (UTC)

I guess I am just not really sure how to square that with the results grabbed by the <code>xlate_wikidata</code>/<code>Wd</code> function, which does not have this format, but maybe I can also try and extract a four-digit string from the result. It just feels a bit hacky, when Wikidata has a date/time system that includes levels of precision, which would feel cleaner.

:::::That actually seems to work! Thanks @[[User:Trappist the monk|Trappist the monk]]! [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 07:19, 4 June 2025 (UTC)
:@[[User:Julius Schwarz|Julius Schwarz]] It doesn't look like it worked in the May 16th version of the main template either, before my changes were implemented. I inserted some debugging statements into the code, and it looks like the "individual members date" line is calling <syntaxhighlight lang="lua" inline>xlate_wikidata("qualifier", "Q208242", "P2124", "P585", "", "reference=no", "preferred=yes", "raw=no", "linked=no")</syntaxhighlight>, which in turn calls <syntaxhighlight lang="lua" inline>require('Module:European_and_national_party_data/Wd')['qualifier']({"", "preferred", "", "", "Q208242", "P2124"})</syntaxhighlight>. Since <code>value_of_qualifier</code> is "", the qualifier ID is not being sent to <code>Wd</code>, and therefore nothing is being returned. <span class="nowrap">--[[User:Ahecht|Ahecht]] ([[User talk:Ahecht|<b style="color:#FFF;background:#04A;display:inline-block;padding:1px;vertical-align:middle;font:bold 50%/1 sans-serif;text-align:center">TALK<br />PAGE</b>]])</span> 15:30, 3 June 2025 (UTC)
::@[[User:Julius Schwarz|Julius Schwarz]] [[Special:Diff/1293776278]] fixes that test case, but I don't know enough about the module to say whether that will break anything else. <span class="nowrap">--[[User:Ahecht|Ahecht]] ([[User talk:Ahecht|<b style="color:#FFF;background:#04A;display:inline-block;padding:1px;vertical-align:middle;font:bold 50%/1 sans-serif;text-align:center">TALK<br />PAGE</b>]])</span> 16:18, 3 June 2025 (UTC)
:::Thanks a lot for this, @[[User:Ahecht|Ahecht]]! I really appreciate. I will have a close look tomorrow, but it should not break anything. As for the reason why it may not have worked before either, it might be because there was an error in the code; I fixed one just earlier today -- even if it didn't actually solve the issue in the present code. In the code you quote, how come "P585" disappears between the two lines? I mean, it makes sense for there not to be a <code>value_of_qualifier</code>, since this is what we are trying to grab.

::::@[[User:Julius Schwarz|Julius Schwarz]] The way the code was written originally (even before my changes) was to not include the qualifier if <code>value_of_qualifier</code> was blank. Since the fifth parameter is <code>""</code>, it didn't include <code>P585</code>. <span class="nowrap">--[[User:Ahecht|Ahecht]] ([[User talk:Ahecht|<b style="color:#FFF;background:#04A;display:inline-block;padding:1px;vertical-align:middle;font:bold 50%/1 sans-serif;text-align:center">TALK<br />PAGE</b>]])</span> 20:33, 3 June 2025 (UTC)
:::::Maybe I am not understanding but, to me, P585 is not the value of the qualifier, it is the qualifier_id, the value would be the date itself. In some cases we already know the value of the qualifier, but here we ask for it. Don't know whether this is clear. I guess what I am trying to say is that if it works, then wonderful, but I am not sure I understand what changed just yet :) [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 20:37, 3 June 2025 (UTC)
