Unable to yank / copy in neovim

tagptroll1 commented 1 month ago

Tested with

neovim v0.11.0-dev-621+g172cc23d8
latest stable v0.10.1

There is no way for me to extract text from neovim to the clipboard. I've tried the + and * registry, setting these as defaults in my config, ctrl + shift +C and right click copy the highlighted text.

# apt list --installed | grep cosmic-term  
cosmic-term/noble,now 0.1.0~1723901703~24.04~8c55fef amd64

This is making the terminal unusable as a daily driver, any assistance would be greatly appreciated!

Do you have clipboard set to unnamedplus?
Do you have an applicable clipboard tool installed, from the ones listed in :help clipboard?
More info about your environment could be helpful (X11 or wayland, compositor, WM/DE, ...)

@MoSal Sorry for the late reply. I have tried having clipboard set to unnamedplus and unnamed. I have both xsel and xclip installed (and $DISPLAY echos to :1) I'm on PopOS 24.04 With cosmic-de / wayland. inxi output for more details:

Since you are on Cosmic (Wayland), do you have wl-clipboard installed?

tagptroll1 commented 1 month ago

I did not, i tried to install it but it did not solve my issue. Still unable to yank or right-click copy anything out the terminal with neovim. I also noticed I also seem unable to paste anything through P in neovim. I have to ctrl+shift+V while in insert mode to actually paste anything in.

MoSal commented 1 month ago

When you yank text, do you see a wl-copy process, something similar to this:

% ps aux | grep wl-copy
user1   1945872  0.0  0.0   2672   644 ?        S    23:20   0:00 /usr/bin/wl-copy --type text/plain

Does wl-copy work when used directly, e.g. wl-copy 'some text' from one terminal, and Ctrl-Shift-v in another terminal?
Does running wl-paste in a terminal work (it prints clipboard content)?

tagptroll1 commented 1 month ago

I did them backwards, but wl-copy and wl-paste works (between different cosmic-terminals), yanking doesn't change anything with processes. I started `htop --filter "wl-copy" before opening neovim and yanking. This was the result before and after (same)

https://github.com/neovim/neovim/blob/0ebc4de0ff93e4edf853b177eb5b1eb898510423/runtime/autoload/provider/clipboard.vim#L96-L101

elseif !empty($WAYLAND_DISPLAY) && executable('wl-copy') && executable('wl-paste')
    let s:copy['+'] = ['wl-copy', '--type', 'text/plain']
    let s:paste['+'] = ['wl-paste', '--no-newline']
    let s:copy['*'] = ['wl-copy', '--primary', '--type', 'text/plain']
    let s:paste['*'] = ['wl-paste', '--no-newline', '--primary']
    return 'wl-copy'

If g:clipboard is undefined (check with :echo g:clipboard), and WAYLAND_DISPLAY is exported, then the above code path should be executed. So try to figure out why it's not, or why it's failing.

Hmm... when I open a new nvim instance and try to yank I get "clipboard: No provider. Try ":checkhealth" or ":h clipboard" Checking health gives me Clipboard (optional)

OK clipboard tool found: wl-copy

Closing the healthcheck, going back to my document I am suddenly able to yank to the + register, but not "" or just yanking without targeting a clipboard. This is with clipboard set to unnamed or unnamedplus.
I am not able to yank without a register, or to + or `` before "checkhealth-ing"

I should add. I also do not get the same "clipboard: No provider..." warning when using any yank alternatives after checkinghealth. It just wont register to my computers clipboard unless i use the + register, and checking health :thinking:

@tagptroll1

I don't know about Cosmic, but primary clipboard is not supported in all Wayland compositors. I just tested with weston, and it's not supported there for example.

% wl-copy --primary 'hi hi'
The compositor does not seem to support primary selection

You can test by passing --primary to wl-copy/wl-paste (or using Shift-Insert for pasting).

If that's the issue here, you can report it to the applicable project.

Seemed to work fine

~ $ wl-copy --primary "hihi"                                                                      21:55
~ $ wl-paste --primary                                                                            21:55
hihi

Cool. Update to the latest version, and test with double-clicking some text, then Shift-Insert. If that works, then the primary clipboard is definitely working in the terminal. So whatever issue you're having is probably not related to the terminal or Cosmic.
