Following the discussion on the Lua talk page, here is the roadmap for the template and module:

Is there a way to made a testcases page for ModuleEUPPs/sandbox to test the impact of the proposed code?

Note: "for the 'share' outputs, should the output have a '%' suffix?" -> I would say no, as my idea was to use this for charts that need a percentage value (as a number, not a string). Julius Schwarz (talk) 08:03, 25 March 2025 (UTC)[reply]

I've copied the tests from User:Julius Schwarz/sandbox into {{test case}} templates at Template:SeatsEUPPs/testcases. I have also changed {{SeatsEUPPs/sandbox}} to use Module:SeatsEUPPs/sandbox. From the ~/testcases results, you can see that the live template rarely agrees with Module:SeatsEUPPs/sandbox. At a glance, testing the live module against the live template in ~/testcases gives similar results. No doubt, the live template uses it parameters differently from the modules.

To change the live template so that it uses the live module, copy the contents of the {{SeatsEUPPs/sandbox}} to {{SeatsEUPPs}}. In {{SeatsEUPPs}}, change the invoke to {{#invoke:SeatsEUPPs|main}}. Save.

Look at ~/testcases again. All tests should produce similar results; the flagged tests should be the result of different error message formatting.

How would one go about adding that "%"? Julius Schwarz (talk) 22:18, 25 March 2025 (UTC)[reply]

With the concatenation operator: ..'%'

@Trappist the monk as you can tell, I am rather new to modules. My idea was that, by creating the module, we would use it directly in relevant pages. But from your last comment about the way forward, I have a sense that we will keep using the template. Does this mean that we should rewrite the template to call the module? For instance, the revised template would be {{SeatsEUPPs|EP|EPP}} and this would actually call {{#invoke:SeatsEUPPs|main|EP|EPP}}? Is it just for writing convenience, then? Julius Schwarz (talk) 08:09, 25 March 2025 (UTC)[reply]

I have no problem with using module invokes in article text... But, not all editors are sufficiently technically minded to do that. The template hides the function call (main) from editors.

The nice thing about Module:Arguments is that it automatically fetches arguments from the both the frame and the parent frame. Writing {{#invoke:SeatsEUPPs|main}} in the template will hand the parent frame parameters (from the template call in article wikitext) to the module. You can see this working in {{SeatsEUPPs/sandbox}}:

{{SeatsEUPPs/sandbox|EP|EPP}} → {{SeatsEUPPs/sandbox}}

Yeah, I have to admit that's neater this way. Thanks, it's all looking really clear. Julius Schwarz (talk) 21:35, 25 March 2025 (UTC)[reply]

Hi @Trappist the monk, before you bow out, allow me to ask one more thing. I started replacing raw calls to wikidata with the module and it hit me that, in most cases, this is being used as part of a composition bar. Not always, but super often.

And all of a sudden, it became a bit irresistible to make another module, based on Module:SeatsEUPPs that would spit out the composition bar :D Now, I got the gist of most of the process, but I could use a quick hand to write the part that actually writes the composition bar using our module. Would you mind having a look? It's at Module:Sandbox/Julius Schwarz/CompositionBarEUPPs Julius Schwarz (talk) 21:43, 25 March 2025 (UTC)[reply]

Forking is a bad idea. Instead, add a new exported function to Module:SeatsEUPPs/sandbox that calls the necessary local functions to produce the output that you want. I've started a function composition_bar() at the bottom of ~/sandbox, added some comments and questions there. Improve on that.

{{#invoke:SeatsEUPPs/sandbox|composition_bar|EC|EPP}} → {{#invoke:SeatsEUPPs/sandbox|composition_bar|EC|EPP}}

Well noted. I started having a look at the comment you made. For line 346, indeed, share has no place here. That was in case "%" or "share" ended up as the party argument. Not happening here. And I will introduce data validation for width and percentage. However, I hit the same issue three times: 1) width should be a percentage and not a number should we can input it as a number but we have attach a "%" sign; 2) I have to attach a "#" sign to the hex code; and 3) I might attach a "%" for seats_share. In all three cases, I am not sure how to concatenate text. Julius Schwarz (talk) 23:57, 25 March 2025 (UTC)[reply]

According to the {{Composition bar}} documentation, width specified as without units assumes px. The documentation also says that the template will also accept % and em units. I've added a snippet of code to validate the width value. Should probably be a separate function. Also added '#' to the color.

—Trappist the monk (talk) 00:45, 26 March 2025 (UTC)[reply]

Thanks and now indeed the colour displays properly. I did a similar operation to add "%" to the share_fc function, but reverted it as bar charts may need to do some calculation on the percentage, so better to leave it out until I create a separate function for this :) Julius Schwarz (talk) 08:05, 26 March 2025 (UTC)[reply]

Thanks for the help @Trappist the monk. I think we are nearing completion. I updated the roadmap above and I think when these items are done this can be considered completed for the time being and I will start using it on all relevant pages. Julius Schwarz (talk) 11:02, 27 March 2025 (UTC)[reply]

If {{CompositionBarEUPPs}} is going to mimic {{composition bar}}, it seems to me that {{CompositionBarEUPPs}} should use the same parameter names for the options:

• |background-color=
• |border=
• |width=
• |per=
• |ref=

That means no {{{3}}}, {{{4}}}, {{{5}}}.

To override the wikidata-supplied bar color we might reinstate {{{3}}} for use as {{composition bar}} uses it, or create a new option parameter |bar-color=. This latter would be my preference. Of course, I would also spell-out |percent= and |reference= (and also rename {{CompositionBarEUPPs}} to {{Composition bar EUPPs}} or better, {{EUPP composition bar}} because English is written with space characters between words; I might even suggest {{EUPP seats}} as a better name).

—Trappist the monk (talk) 14:35, 27 March 2025 (UTC)[reply]

That seems all very sensible. For the colour element, I think it is nice to have it, but it should just be the exception; by default, we just take the registered party colour. And I am happy to rename the modules and templates. As for the arguments, like I wrote in the table, I was unfortunately stuck when I tried to use something else than 'yes' for percentage or reference, for instance. Julius Schwarz (talk) 14:58, 27 March 2025 (UTC)[reply]

I've added a 'thisparty' test to validate_institution_party(). Seems to work, you might want to test it further.

—Trappist the monk (talk) 15:27, 27 March 2025 (UTC)[reply]

Added support for |width= ({{{3}}}), |pc= ({{{4}}}), and |ref= ({{{5}}}). Still to do is to remove support for those positional parameters.

—Trappist the monk (talk) 16:16, 27 March 2025 (UTC)[reply]

Rewrote get_colour(). The hash prefix is added there because it should be possible to use named colors in |bar-color= (which overrides the wikidata color). Other color parameters also appear to be working:

{{EUPP composition bar/sandbox|EC|EPP|bar-color=blue|border=red|background-color=#3a3}} → {{EUPP composition bar/sandbox}}

|percent= and |ref= are now case-insensitive. Positional parameters {{{3}}}, {{{4}}}, and {{{5}}} are now ignored.

Thanks for this, @Trappist the monk; this is now all reflected in the testcases and it is all working correctly. I will therefore move the code to the main module and update the documentation accordingly. Julius Schwarz (talk) 09:08, 28 March 2025 (UTC)[reply]

In the module sandbox, I have streamlined seats() and seats_share(). Template:EUPP seats/testcases seems to show that I did not break anything. If you agree then the live module should be updated from the sandbox.

—Trappist the monk (talk) 15:42, 28 March 2025 (UTC)[reply]

The changes are deployed and I confirm that nothing is broken! However, I started having a look at translation and it won't be as easy as planned since the Wikidata templates are not the same on all wikis. I think I can handle it, though. Julius Schwarz (talk) 15:52, 28 March 2025 (UTC)[reply]

Just wanted to massively thank @Trappist the monk for their help on this. Given my own knowledge of Lua (or lack thereof), none of this would have been possible without them, and the code in the articles look much much neater now! I also learned a whole lot, which feels great. Admittedly, this does not impact too many pages per wiki, but it is directly applicable to many other wikis, so I look forward to working on translating it and replicating it!
