From: Jiamu Sun <39@barroit.sh> Date: Tue, 10 Mar 2026 11:40:59 GMT Subject: [PATCH v3 0/8] parseopt: add subcommand autocorrection Message-ID: In-Reply-To: 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. By default, this implementation enables autocorrection for builtins with mandatory subcommands. However, for those using PARSE_OPT_SUBCOMMAND_OPTIONAL, autocorrection is skipped to avoid misinterpreting legitimate unknown arguments as mistyped subcommands. To allow builtins with optional subcommands to explicitly opt in, this series adds the PARSE_OPT_SUBCOMMAND_AUTOCORR flag. This flag is subsequently enabled for git-remote and git-notes. Additionally, the existing autocorrection logic is extracted from help.c so subcommand handling can reuse the same config parsing and prompt/delay logic. Some split string literals are also combined so the full text is easier to grep for. Changes in v3: - Align with the coding guildline Changes in v2: - Reword the explanation of default autocorrection behavior Jiamu Sun (8): parseopt: extract subcommand handling from parse_options_step() help: make autocorrect handling reusable help: move tty check for autocorrection to autocorrect.c autocorrect: rename AUTOCORRECT_SHOW to AUTOCORRECT_HINTONLY autocorrect: provide config resolution API parseopt: autocorrect mistyped subcommands parseopt: enable subcommand autocorrection for git-remote and git-notes help: add tests for subcommand autocorrection Makefile | 1 + autocorrect.c | 89 +++++++++++++++++ autocorrect.h | 21 ++++ builtin/notes.c | 10 +- builtin/remote.c | 12 +-- help.c | 104 ++++---------------- parse-options.c | 156 ++++++++++++++++++++++-------- parse-options.h | 1 + t/t9004-autocorrect-subcommand.sh | 51 ++++++++++ 9 files changed, 305 insertions(+), 140 deletions(-) create mode 100644 autocorrect.c create mode 100644 autocorrect.h create mode 100755 t/t9004-autocorrect-subcommand.sh base-commit: 795c338de725e13bd361214c6b768019fc45a2c1 -- 2.53.0
