Not working under WSL2 (tcgetpgrp failed: Not a tty)

[monologconnor]

Hi, there!
I just found this plugin and installed it via lazy.nvim

When I tried this plugin under the Powershell environment, everything works well, however when I entered the :PasteImage command under the WSL environment, following error occured (I got no idea on why the error output is not selectable so I have to take screenshot. There are also some character displaying issue might due to my system language):

I have also checked this issue #34, but it seems like not related.

Thanks for your help!

Hi, just switched to another device and get the correct displaying error output like below, hope it helps

Thanks!

Can confirm this is an issue. Occurs in both alacritty and normal windows terminal.

With the health patch, and modifying the powershell command, I'm able to get :PasteImg working in WSL.

But the tcgetgrp failed occurs, and the terminal starts freaking out and neovim doesn't refresh the screen properly, leaving artifacts behind, until I close out of the terminal.

I just modified the powershell command in the utils file to the following, which is simpler and avoids as many special characters.

cmd_check = 'powershell.exe "(Get-Clipboard -Format Image)"'
cmd_paste = 'powershell.exe "(Get-Clipboard -Format Image).save(' .. "'%s'" .. ')"'

I did troubleshoot this to at least narrowing it down to being able to run this to reproduce this issue with neovim wigging out after :PasteImg is run.

:lua print(require('clipboard-image.utils').get_clip_content('powershell.exe "(Get-Clipboard -Format Image)"'))

And after this single command is run, neovim no longer refreshes properly. I'm guessing something to do with the os.popen.

That might actually be a neovim bug. os.executue('powershell.exe /?'), causes the same issue... Weird.

[diablozzq]

So may be two bugs.

1. Neovim wigging out - have no clue, can reproduce with os.execute. Trying to reproduce without plugins....
2. tcgetgrp failed. - May be a powershell path issue with using powershell from within WSL. See the scrapy issues.

scrapy/scrapy#4589

Did some more testing. I disabled this plugin, and was able to reproduce some issues. So likely some neovim issues to resolve lol.

These fixes definitely fixed the paste not working:

cmd_check = 'powershell.exe "(Get-Clipboard -Format Image)"'
cmd_paste = 'powershell.exe "(Get-Clipboard -Format Image).save(' .. "'%s'" .. ')"'

But when we use the "os.execute" within WSL right now, it causes some issues with Neovim not refreshing.

And using os.execute with powershell.exe on WSL is what causes the tcgetgrp error. If you use it with another command, no error.

Edit: was able to use io.pipe instead of os.execute to get rid of the tcgetgrp error. Only have to figure out why neovim wiggs out now... lol

Edit2: Nvim inside tmux seems to do MUCH better at not getting bugged screen refreshing.... So tmux + io.pipe + fixed powershell command + fixed help = fully working markdown paste image.

Alternative would have been just sending the above powershell command directly to a terminal... wouldn't have been that hard.

I fixed powershell command and create PR. #44
and also you can create a PR as your great work.
