Wow, nice! Did you use the VisualStudio functionality to move all the strings?
Should I open a PR to your branch for the German translation, or create a new PR when this one is merged?

I used Atom and my mouse to move all the strings 🤕, but I based the changes on a demo from Microsoft, so it should match up with how VS would do it:
https://code.msdn.microsoft.com/CSWinFormLocalization-59675a87

As for a Deutsch PR, either way is fine with me. I'd be happy to include it here or add it later.

Wow, that must have been a lot of work.
Okay, I will do the PR to your branch then, since I found some things to correct (missing strings, formatting...), I can include them in my PR this way.

Just an idea: What about an option to set the language manually? Can imagine some people wanting it.

And a FYI: You can set the localization yourself in the code if you add those 3 lines (found here) as early as possible (before any localized strings are loaded), e.g. right at the start of GUI.Main():

System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo("en-US");
System.Globalization.CultureInfo.DefaultThreadCurrentCulture = ci;
System.Globalization.CultureInfo.DefaultThreadCurrentUICulture = ci;

If you want to test the German translation for example later on. If you found a better way to do this, I'm all ears.

If you found a better way to do this

That was exactly how I did it. :) Except I only set one of those.

Wow, massive piece of work there, @HebaruSan! Is this ready for our point release, or shall we leave it for the next one?

I think it's pretty safe. If there are bugs, they should be of the "this dialog has a strange string here" variety rather than crashes or corrupted installs.

Can somebody by any chance tell me, why my tranlations work when compiling in VisualStudio (2019), but not when when compiling with the BuildTools (15) installed without VS on Windows, nor when compiling on Linux with mono?

And btw, does anybody know how to prevent VS from overwriting all the auto-generated comments?
(See here for example)

The en-US translations seem to be working for me on Mono (after the commit I just pushed):

I'll take a look at your branch shortly...

The en-US translations seem to be working for me on Mono (after the commit I just pushed):

Sorry, forgot an important bit: The normal 'per form' translations work perfectly fine, just the translations of Properties/Resources.de-DE.resx (so 'dynamic' strings) are missing, the default text is shown.

The Properties/Resources.en-US.resxseems OK on Mono as well (this would say "favourites" otherwise):

Yeah, I'm seeing some weird stuff in de-DE.

I'll let you know if I can figure out why...

Yeah, I'm seeing some weird stuff in de-DE.

Oh that's probably due to mono/mono#12643.
Problem is: I have to use ContentAlignment.MiddleCenter, else one language will always be off-center.

The Properties/Resources.en-US.resxseems OK on Mono as well (this would say "favourites" otherwise):

Well, it does say 'favourites' on my system (with en-US)...
Seems I changed something (probably in CKAN-GUI.csproj) by accident. You tested on my branch, right?
That's weird...

BTW, in case it's useful, my command for testing on Linux is:

LC_ALL=de_DE _build/ckan.exe

Oh that's probably due to mono/mono#12643.

Huh, you're right. I have a local build of mono's current HEAD (which includes that PR), and it works there:

You tested on my branch, right?

My "favourites" test was on my branch, to establish a baseline of whether there's a known-working version here. I'm checking your branch now.

This is where Resources.de-DE.resx broke, it needs to be a SingleAssemblyResourceManager object or it won't check the satellite assemblies bundled in the EXE:

https://github.com/DasSkelett/CKAN/blob/ceae2c58b7f70881fc7eaa0921af0a14f871da9d/GUI/Properties/Resources.Designer.cs#L42

Can you revert all your changes to that file? You should be able to use my version without changes.

Huh, you're right. I have a local build of mono's current HEAD (which includes that PR), and it works there:

I recognize the issues I fixed ;)
It should be fixed since mono-5.16.0.235.

BTW, in case it's useful, my command for testing on Linux is:

LC_ALL=de_DE _build/ckan.exe

Thanks, that might be easier than hardcoding the CultureInfo manually and recompile. Just Windows doesn't offer an option, as always.

I recognize the issues I fixed ;)

Oh nice! I didn't even think to check if that was you. 😆 Congrats on getting that merged!

Will try, thanks 🎉.
Mind if I force-push my branch? Easiest for me is resetting the commit and unstaging the file.

Please do, I won't be making changes to your branch.

Regarding the LinkArea bug (short summary for those reading this and don't want to check the linked PR: Mono doesn't (yet) take text alignment into account when rendering LinkLabels, which makes all non-upper-left aligned LinkLabels unreadable):

It should be fixed since mono-5.16.0.235.

That's wrong it seems, since I run 5.20.1.19which is from April 11th and my PR is not included. So I have no idea how the release mechanism of mono works, and when a PR is included.

Why is this bug a problem for us/me?
I changed the layout of the AboutDialogin my branch so that every (link)label spans from left to right (excluding the last row with three LinkLabels) and set

linkLabel.TextAlign = ContentAlignment.MiddleCenter

for easy centering in every language.
But with the mono bug the dialog is unreadable, most links are unclickable.
Basically, the AboutDialog is unusable like this.
If we stick to this, we must hope that the next mono release includes that fix and everyone updates to it.

A workaround/how it was before: Set the location of every link label for every language (by now only two for this form) manually so they appear centered (which is very fiddly to do!).
But at least you can read something like this.
Another idea: Calculate the string size during runtime and set the position and size accordingly. A bit dirty, but should do it.

Okay, I just found out that the icon problem is not introduced by our changes!
Other CKAN versions (i.e. current master@75deab0) have the same problems, at least on my system. It just never noticed it. But as I tested if you can remove the icon of the resource files, I obviously put attention there and spotted it.

From my side only the issue with the wrapping menu entry is left now.

the wrapping menu entry

This issue is unreal! There's nothing different in how we treat that object, but that effect is completely consistent and persistent no matter what changes I make.

... I think we're looking at a one-in-a-million Mono bug related to the exact pixel length of the resource string. I tried changing it to "afsdkamjsldk fdjklpa" (same number of characters with same grouping, but the letters aren't the exact same width) and it started working normally. But as long as the exact text is "Empfehlungen ansehen", it goes weird. Can you think of a slightly different translation for that string?

"Empfehlungen installierter Mods", translated to "Recommendations of installed mods" should fit well.

👍
Mono is so weird.

So we're all good to merge this, now? Are we sure those weird alignment errors don't appear with different app window sizes, or something like that?

So we're all good to merge this, now?

@HebaruSan needs to rebase once more for #2762.
@HebaruSan, if you want to include the German translation for the new string yourself, I suggest "Durchsuche GameData nach DLCs und manuell installierten Modulen...".

Are we sure those weird alignment errors don't appear with different app window sizes, or something like that?

I don't remember if I tried resizing the window, but I doubt that would affect the issue. Resizing the dropdown menu at least didn't fix it.
I can try it out tomorrow.

So after the rebase you have a Go from my side 👍.

Rebased!

I suggest "Durchsuche GameData nach DLCs und manuell installierten Modulen...".

I decided the English string sounded better without GameData. Does "Durchsuche nach DLCs und manuell installierten Modulen..." make sense?

"Suche nach DLCs und manuell installierten Modulen..." (without the "Durch") would be a bit more natural.

@politas, yes, this is ready now. I haven't merged it because I wasn't sure whether to count it as "reviewed" given that both @DasSkelett and I have made commits to the branch.

I don't remember if I tried resizing the window, but I doubt that would affect the issue. Resizing the dropdown menu at least didn't fix it.

No, resizing the window does indeed nothing. Would have been weird, because I'm sure @HebaruSan doesn't use the exact same window size, and it happened on his system too.

Is it possible to add the translation files into a separate folder like en-US and de-DE, because every translation wil add 18 new files. This way it would be easier to find a specific language file and will prevent the GUI folder to get cluttered with .resx files.

Good idea. Rebased to get the NuGet updates and moved those to a Localization/de-DE folder. I couldn't figure out how to make it work with Resources.de-DE.resx, but those are already in the Properties folder so that shouldn't be as much of a problem.

For me this is good to merge. If nobody finds any alignment errors anymore for the German translation, this can be merged.
