Packaging and running OurPaint and LaGUI https://twitter.com/ChengduLittleA/status/1609921080923402241

• Does exist a public development repository?

• At first launch of OurPaint ~/preferences.udf is created, this should go in ~/.config/ourpaint (or ~/.config/OurPaint) (XDG stuff https://wiki.archlinux.org/title/XDG_Base_Directory)

• LaGUI without fonts fails in package() step because there aren't the fonts

• OnePaint can't find systems fonts, I have installed the noto-fonts packages in the official Arch repo noto-fonts, noto-fonts-cjk, noto-fonts-emoji, noto-fonts-extra. Didn't check on AUR

• LaGUI (with fonts) install them in ~.local/share/fonts/lagui/ this is not welcome in Arch packaging

• OurPaint can't find one of the fonts even if it is installed in ~/.local/share/fonts/lagui/ and segfault

Hi! I'm the author of Our Paint and LaGUI.

I sort of developed Our Paint for it to be portable so I packaged those fonts together with the program so if the appimage runs it will simply check its own directory. It's just so that fonts especially CJK ones are rather big and apparently a lot of systems doesn't come with that by default. The reason I didn't install those fonts into more "known" location in the system is because for some systems that has these fonts they might get overwritten and there are some differences with e.g ubuntu's cjk font file and the one acquired from google's site (I don't know the exact reason, but I suppose licensing and font variant localization plays a part), and to overwrite those system fonts might not be desired either. The fonts installed in .local/share/fonts/lagui are mostly for convenience of developing LaGUI programs, and those programs will be shipped later with font files directly packaged within. (LaGUI is a static lib, and users should not need to install LaGUI dev packages when they receive a LaGUI-based application)

Same with user preferences and brush files for portability. I think I can save a copy of preference inside .confg too. I did know XDG base directories so I think I can make it happen.

Does exist a public development repository?

I haven't quite set up a public repo yet, my web server is acting up on some of those stuff. Also the repo needs some additional cleaning. I'll notify here and on my page when public repo is okay to go.

OurPaint can't find one of the fonts even if it is installed in ~/.local/share/fonts/lagui/ and segfault

I found the issue. My font loading function for mono font didn't anticipate this path while regular font loading do. I'll fix this behaviour. LaGUI programs will search 11 different paths for these fonts, if you put the font directory simply adjacent to the executable it will find it.
