Subject: [PATCH v3 07/12] builtin/show-ref: stop using global vars for `show_one()`
Date: Tue, 31 Oct 2023 09:16:38 +0100 [thread overview]
Message-ID: <bc528db7667cbe9323162b80ad47bc9d46c4b275.1698739941.git.ps@pks.im> (raw)
In-Reply-To: <cover.1698739941.git.ps@pks.im>
[-- Attachment #1: Type: text/plain, Size: 6148 bytes --]
The `show_one()` function implicitly receives a bunch of options which
are tracked via global variables. This makes it hard to see which
subcommands of git-show-ref(1) actually make use of these options.
Introduce a `show_one_options` structure that gets passed down to this
function. This allows us to get rid of more global state and makes it
more explicit which subcommands use those options.
