Subject: [PATCH v3 2/3] libgit-rs: add get_bool() method to ConfigSet
Date: Sat, 27 Sep 2025 03:51:50 +0000	[thread overview]
Message-ID: <479c263bc19aa5cdfe9d990b2521f88b1620759c.1758945111.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1977.v3.git.1758945111.gitgitgadget@gmail.com>

From: ionnss <zara.leonardo@gmail•com>

Add support for parsing boolean configuration values using Git's
git_configset_get_bool() C function. This ensures consistent behavior
with Git's native boolean parsing logic.

The method handles all Git boolean formats (true/false, yes/no, on/off,
1/0) and edge cases like "00" and "100" correctly.

Includes comprehensive tests for various boolean formats and edge cases.
