Description

Pressing <tab> after any partially-completed command won't do anything - neither triggers the Pmenu nor completion.

Steps to reproduce

Start typing :P<tab>

Expected behavior

Pmenu and completion for commands starting with P will show up.

Actual behavior

Just nothing... literally nothing...

Additional context

This is pretty much the minimal config plus the cmp.setup.cmdline(":") bit which causes it to fail. Setting up cmdline completion for "/" seems to work fine. This could be related to hrsh7th/cmp-path#38.

[axieax]

oo I tried using cmp.mapping.preset.insert() instead of cmp.mapping.preset.cmdline() and I get my previous issue of ^I characters appearing every time I press <Tab>.

[hrsh7th]

Sorry. I can't understand.

You specified the source for cmdline is path only. So I think if you don't type ~/, nvim-cmp can't show anything.

[axieax]

So I think if you don't type ~/, nvim-cmp can't show anything.

Actually using the path source works. It just also breaks normal command mode behaviour (i.e. without path).

[hrsh7th]

It just also breaks normal command mode behaviour

Please explain what is your expected behaivior?

[axieax]

The expected behaviour is what was defined above in the initial issue post - basically getting completion for my command. Previously, typing :P<Tab> would bring up the Pmenu, but now it does not anymore.

[hrsh7th]

Sorry. I don't know how to achive this without side-effect.
Do you know other plugin that achieve your expected behavior?

[axieax]

Hmm that's weird, everything was working fine before 801a9f9

[hrsh7th]

Ah. Sorry. Maybe the above commit fixes this issue. Could you try latest nvim-cmp?

[axieax]

Unfortunately that didn't fix it :((

[hrsh7th]

really??? In my environment, the last commit fixes this perfectly...

[axieax]

Hmm I'm not sure, but it doesn't seem to work with my default config or the minimal config provided above :((

EDIT: it's because I forgot to updated the plugin oops lemme try again

[axieax]

Works perfectly tysm @hrsh7th :))

[cexoso]

I has the some question, so how you guys resolve the problem? what does the "updated the plugin oops" mean?

it worked, see #809

[axieax]

Sorry by "update the plugin", I mean fetching the latest commits from the plugin (haven't use Vim-plug for a very long time haha). Good to hear it works now. I'll just leave my config here as a reference for others.
