Subject: [PATCH v3 2/7] strbuf: split out logic to humanise byte values
Date: Mon, 15 Dec 2025 14:56:34 -0600 [thread overview]
Message-ID: <20251215205639.2700270-3-jltobler@gmail.com> (raw)
In-Reply-To: <20251215205639.2700270-1-jltobler@gmail.com>
In a subsequent commit, byte size values displayed in table output for
the git-repo(1) "structure" subcommand will be shown in a more
human-readable format with the appropriate unit prefixes. For this
usecase, the downscaled values and unit prefixes must be handled
separately to ensure proper column alignment.
Split out logic from strbuf_humanise() to downscale byte values and
determine the corresponding unit prefix into a separate humanise_bytes()
function that provides seperate value and unit strings.
