* [PATCH v5] help.c: expand options for help.autocorrect @ 2020-11-24 16:37 Drew DeVault 2020-11-24 21:43 ` Junio C Hamano 0 siblings, 1 reply; 3+ messages in thread From: Drew DeVault @ 2020-11-24 16:37 UTC (permalink / raw) To: Junio C Hamano, git; +Cc: Drew DeVault, lanodan While help.autocorrect can be set to 0 to decline auto-execution of possibly mistyped commands, it still spends cycles to compute the suggestions, and it wastes screen real estate. Update help.autocorrect to accept the string "never" to just exit with error upon mistyped commands to help users who prefer to never see suggested corrections at all. While at it, introduce "immediate" as a more readable way to immediately execute the auto-corrected command, which can be done with negative value.

I do not think we should place too much stress on things that are there for "historical reasons"---they do not deserve their own paragraph. That is why the version I queued with tweak said: ... If this value is 0, the suggested corrections will be shown, but not executed. If it is a negative integer, or "immediate", the suggested command is run immediately. If "never", suggestions are not shown at all.

We'd probably want to also add a test for immediate. Taking them together, perhaps like the attached patch.
