From: Jiamu Sun <39@barroit.sh> Date: Sun, 08 Mar 2026 12:17:20 GMT Subject: [PATCH 0/5] parseopt: add subcommand autocorrection Message-ID: Git currently provides auto-correction for builtins and aliases, but lacks this functionality for subcommands parsed via the parse-options API. Subcommands are also commands, and typos will occur, too. Like: git remote add-rul So, this series introduces subcommand auto-correction. Currently, builtins with mandatory subcommands enable autocorrection by default. However, those using PARSE_OPT_SUBCOMMAND_OPTIONAL skip it to avoid treating valid unknown arguments as mistyped subcommands. This series adds PARSE_OPT_SUBCOMMAND_AUTOCORR, allowing commands with optional subcommands to explicitly opt in to autocorrection. It then enables this flag for git-remote and git-notes. Additionally, it extracts the existing autocorrection logic from help.c so subcommand handling can reuse the same config parsing and prompt/delay logic.
