Darktable version 4.4.2

[trougnouf]

Did you add dtmediawiki to your luarc file?

[trougnouf@bd ~]$ cat ~/.config/darktable/luarc 
require "contrib/dtMediaWiki/dtMediaWiki"

Is Lua properly installed and dtMediaWiki is in your darktable/lua/contrib directory? (eg /usr/share/darktable/lua/contrib/dtMediaWiki/)

If so you can run darktable as darktable -d lua and it should give you an error message describing what went wrong.

[vitaly-zdanevich]

I checked your paths - yes and yes.

Tried darktable -d lua - empty terminal

[vitaly-zdanevich]

OOps, I found that on my Gentoo - I need to enable Lua USE flag, will try now...

[vitaly-zdanevich]

darktable -d lua:

Darktable 4.6.0

[trougnouf]

Do you have lua-sec installed? (It's one of the dependencies listed in the README)

[vitaly-zdanevich]

On my Gentoo I emerged luasec 1.3.2 (the url is https://github.com/brunoos/luasec) but still the same error.

[trougnouf]

You should have the file /usr/share/lua/5.4/ssl/https.lua then. Maybe it's installed for a different lua version?

[vitaly-zdanevich]

I have another version: 5.1

[trougnouf]

Darktable uses Lua 5.4 so you would need that.

I don't know if you can get away with copying the content of /usr/share/lua/5.1 into /usr/share/lua/5.4 (They are not binaries and I believe that darktable has its own Lua 5.4 built-in so maybe?)

Or you may be able to compile with DONT_USE_INTERNAL_LUA set to OFF.

Either way it's an issue with Darktable (not supporting other versions of Lua) and Gentoo (not shipping Lua 5.4), there is nothing we can do here to fix your issue.

Now I see it, is inputs width can be increased?

[trougnouf]

Now I see it, is inputs width can be increased?

I don't think so. There is limited control in what we can do there (per the documentation on https://darktable-org.github.io/luadocs/lua.api.manual/darktable/darktable.preferences/ ). Maybe it would be done in darktable's CSS?
