[Feature Request] tab completion for / commands

[ndrew222]

I see that when you type /, a completion menu pops up. It would be great if you could press Tab to access the suggestions.

Even better would be to add subcommand completion, but I'm not sure how that would be implemented

Just in case you weren't aware, you can access the suggestions via Tab then Enter to select the highlighted entry (which inserts it into the text input). An option could be added to have the command inserted via Tab itself.

I like the idea of adding auto-completion to sub-commands. In the meantime, sub-commands are currently listed in the tooltip of the sub command argument in the command description (if enabled).

Oh! I was not able to see that because the highlighted entry is so barely highlighted in my current theme lmao Thanks

[ndrew222]

do you know which parameter in the theme I should change for the command highlight?

I'd like to see this happen, too.

To my experience, there are two styles for choosing completion candidates from a tooltip or pop-up:

• TAB cycles through the candidates, RET inserts the candidate
• arrow up/down selects the candidate, TAB inserts it

In that light, a new configuration option would probably be needed to switch between the two.

For the sake of example:

# Type: string
# Values: "enter", "tab"
# Default: "enter"

[buffer.text_input.autocomplete]
insert_key = "enter"

It would also seem useful to me, if it were possible to turn off the wrap-around between completion candidates, i.e. so that it stops when the first or last candidate is reached.

For instance:

# Type: boolean
# Values: true, false
# Default: true

[buffer.text_input.autocomplete]
cycle = true
