I've tried using this new version of pspg with the --clipboard-app=4 parameter, and when I press the Ins key to copy some information to the clipboard, I receive the following error:

Cannot write to clipboard (clip.exe) (press any key)

clip.exe is available and works in the same way as pbcopy; for example:

echo Test | clip.exe

... effectively copies the Test text to the clipboard.

Is it possible for pspg to use clip.exe in the same way that it is using pbcopy?

I've tried using this new version of pspg with the --clipboard-app=4 parameter, and when I press the Ins key to copy some information to the clipboard, the text is now copied correctly. Thank you for this useful addition to pspg!

If I ran pspg without the --clipboard-app=4 parameter, the clipboard detection algorithm automatically selects xclip instead of clip.exe, since xclip is also available in my WSL2 environment, but it doesn't work because I don't have an X-server running. The error I receive when I press the Ins key in this case is:

 Cannot write to clipboard (Error: Can't open display: :0) (press any key)

Is it possible for the clipboard detection algorithm to look for clip.exe before looking for xclip, so that in a WSL2 environment clip.exe can be automatically selected?

yes, it does https://github.com/okbob/pspg/blob/463ab29b596c316c153acfbfc9a584fe6668073f/src/pspg.c#L1832

There will be always conflict - what clipboard application should be used (when there are more possibilities). This is reason why there are an option --clipboard-app. Maybe I can do check if xserver is defined or not, if this is possible by some way.

[okbob]

Unfortunately is not easy detect, so xserver is not installed or doesn't work. I didn't find any environment variables that should to work on modern and old unixes. You can save this option to configure file, and it should to work

[gus-sipc]

I think it should be safe to check for "clip.exe" first, since a ".exe" program should never be available outside a WSL2 environment.

Inside a WSL2 environment, "clip.exe" is the best option because it is provided by the host Windows operating system. The other clipboard programs provided by Linux environments require further configuration (such as X-server installation) to work correctly with Windows clipboard.

If you agree, I can send a PR to check for "clip.exe" first.
