Shell completion after unexpected word messes up the prompt #596

on Jun 1, 2026 I see that the attempted fix has been rejected because it silences potentially important and informative error messages. I understand that, but it doesn't make the issue itself less annoying. I wonder: could the solution be to adjust the
misecompletion script and make it swallowusagestderr output instead?I.e., the last line of the following block:
do local -a parts=("${(@ps:\t:)line}") values+=("${parts[1]}") descs+=("${parts[2]}") inserts+=("${parts[3]}") [[ "${parts[3]}" == "'"* ]] && needs_menu=1 done < <(command usage complete-word --shell zsh -f "$spec_file" -- "${(Q)words[@]}")
could be changed to:
done < <(command usage complete-word --shell zsh -f "$spec_file" -- "${(Q)words[@]}" 2>/dev/null)
WDYT? This would allow anyone to debug the usage script itself by invoking the appropriate completion command manually (i.e., the error message would be printed on the console), but it would also fix this issue:
$ usage complete-word --shell zsh -f /tmp/usage__usage_spec_mise_2026_7_2.spec -- mise help "" Error: × unexpected word: help
Update:
Just confirming, that using this in
.zshrcworks fine:source <(mise completion zsh | awk '/command usage/ { gsub(")$", " 2>/dev/null)"); }; { print $0; }')

When I attempt to perform shell completion after an unexpected word in an argument with
mise, the verbose error message from usage messes up the shell prompt.For example:
After pressing typing
mise helpand pressing tab, a multi-row error message is printed, and the prompt, including the current input, becomes garbled and overwritten. This makes it really hard to figure out what's already typed and what's new.
