Putting this here first as a draft, I haven't tested it at all. Will update the descriptions after I've done testing.

Shell completions can be added with something like this in post_install

	for _shell in bash fish zsh; do
		vtargetrun ${DESTDIR}/usr/bin/fj completion ${_shell} > forgejo-cli.${_shell}
		vcompletion forgejo-cli.${_shell} ${_shell} fj
	done

Done. Thanks, @hosaka.

You can workaround the cross build issues with something like this:
#57605 (comment)

@Duncaen The cross-build still fails for armv6l, armv7l, and aarch64. The linker can't resolve libgit2, libssh2, libssl, and libcrypto for the cross target. It finds the sysroot libraries but rejects them as incompatible. The _setup_env workaround doesn't seem to help here since the issue is with the linker rather than cc-rs mixing CFLAGS.

Should I restrict the build to x64 and i686 instead? Does that seem reasonable, or is there a better approach for the C dependencies?

Looks like the target is x86_64, so it's building it for the host (for some reason, maybe it's executed during the build) which means you have to add those libraries to hostmakedepends too.

Done :) Thanks

those are deps of libgit2, it should suffice to put just libgit2-1.9-devel in hostmakedepends, side note, it seems to be used by the ssh2-config crate to clone the openssh repo for some reason oO

EDIT: veeso/ssh2-config#23 (comment) - "The list of defaults [algorithms] should be the same as in openssh2-portable - and these need to be kept in sync with new releases of openssh-portable" upstream seems to have taken that suggestion a bit too literally...

@tranzystorekk I've changed the hostmakedepends as per your suggestion, the cross-build failed again with the same incompatibility errors. I gotta change it back to explicitly put the rest of the dependencies on hostmakedepends, I guess.

seems the cc-rs workaround messes with host build, i managed to get this template to cross build if we choose to downgrade cc instead:

	for _shell in bash fish zsh; do

}

Still failed for armv7l with a gnu/stubs-soft.h: No such file or directory error. I'll just go back to @Duncaen's _setup_env suggestion since that had a passing build.
