[Solved] convert extracted filename to lowercase in PKGBUILD

Lone_Wolf · 2024-11-24 12:56:08

I currently have 4 wine prefixes for a Might & Magic 7 : For blood and Honor

vanilla install from cd
gog install
gog install + mod1
gog install + mod2

All 4 have grayface patch installed ( bugfixes and changes to allow running on later directx/windows versions) and the mods also include mmextension .
Currently all those prefixes are created manually on an ext4 /home filesystem .

I expect there will soon be 2 or 3 more as I intend to help testing a mod.
I'm considering to create packages for them.

The original is from around 1998 and uses dos-style uppercase filenames. gog install mixes upper & lowercase names and so do the mods .

As the mods overwrite files from the install the case of the filenames matters.
Fortunately the mods come as zip files and unzip has the option -LL to force lowercase on extraction .

I could download and extract those files manually in prepare() using unzip with that option, but I'd like to put them in source= and let makepkg do the job.

Unzip is fast and takes about a minute to extract the largest mod with 3.1 GiB compressed data.

Is there a way to mount folders case-insensitive ?

If not, how to convert the extracted files and subfolder contents to lowercase efficiently ?

Have you considered using noextract and using the first line of prepare() as your custom extraction with -LL, similar to the 'lrzip' example used in the Wiki?

looks very useful, thanks.

I didn't know there was a noextract array in PKGBUILD, was this recently added ?

It has been there for longer than I have been about here!

For the other part of the question, you can actually enable per dir case insensitivity on ext4 filesystems since some 5.2 kernel or so: https://docs.kernel.org/admin-guide/ext … me-lookups -- though you need to tune2fs enable the casefold functionality on it unmounted if you want to do so after the fact: https://unix.stackexchange.com/a/559022

That reminds me... I've been meaning to enable that on my system for a game that has mods which sometimes rely on Windows' case insensitivity (i.e. basically your situation) but never got around to it, maybe this is the kick in the butt I need.

So there are 2 viable methods :

use noextract= and extract the files using unzip in prepare()

Use the casefold capibility of ext4 (requires changes outside of PKGBUILD) .

Thanls for the responses, declaring solved.
