[bug#59688] [PATCH] gnu: Add zls

[guix-patches--- via <guix-patches@gnu.org>]

[-- Attachment #1: Type: text/plain, Size: 241 bytes --]


Hi,

this is a patch that adds the zls - zig language server. It is not currently
the most recent version, as the project follows versions of zig itself, which
is in guix one version behind. (as zig became self hosted)

Kind regards,
Maya
