Bash integration not working for `--color=(always|never)`

Tested again. Now it's fixed!

Here's what works:

for path in ~/.config/complgen/*.usage; do
    stem=$(basename "$path" .usage)
    eval "
_complgen_jit_$stem () {
    local words cword
    _get_comp_words_by_ref -n = words cword
    local prefix="\${words[\$cword]}"
    local -a completions=(\$(complgen complete \"$HOME/.config/complgen/${stem}.usage\" bash --prefix="\$prefix" -- \${words[@]:1:\$cword-1}))
    for item in "\${completions[@]}"; do
        if [[ \$item = "\${prefix}"* ]]; then
            COMPREPLY+=("\$item")
        fi
    done
    __ltrim_colon_completions "\$prefix"
    return 0
}
"
    complete -o nospace -F _complgen_jit_$stem "$stem"
    unset stem
done

Thanks for reporting!

Still broken: mygrep --color=n<TAB> completes to mygrep --color=--color=never.

I have built using cargo build from latest commit and tested with bash --noprofile --norc -i; source /usr/share/bash-completion/bash_completion.

Take another look please, it should work better now: https://github.com/adaszko/complgen/blob/4927e628c54244114a7d9d691a125333f9eeaafc/README.md#bash-integration

We are getting there. These autocomplete correctly now:

mygrep <TAB>
mygrep --color=<TAB>
mygrep --color=a<TAB>
mygrep --color=al<TAB>

but mygrep --color completes to mygrep =

[adaszko]

mygrep --color<TAB> works on my end:

To be clear, I'm talking about the JIT mode, with Bash and complgen at commit 4927e62. Perhaps you're at some older commit?

[Ordoviz]

I was using this grammar:

complgen/e2e/bash/test_bash_shell_integration.py

Lines 61 to 62 in 4927e62

	mygrep --color "use markers to highlight the matching strings"=<WHEN>;
	<WHEN> ::= always | never | auto;

Changing it to

mygrep --color=<WHEN>;
<WHEN> ::= always | never | auto;

fixes the bug.

Check again please. The issue was Bash weirdness to do with handling $COMP_WORDBREAKS characters in completions (= and : are among which). Special filtering needs to be performed then to get correct results. I did that for shell script output in the past but seem to have forgotten about it for the JIT mode.
