New layer: clipboard support on terminal for multiple systems

[viccuad]

Right now, there doesn't seem to be clipboard support with spacemacs TUI on Linux, and from the gitter chat I get that it doesn't work on other systems too.

Maybe is a good idea to gather here together the relevant configs to make a layer with them, with some layer docs on external dependencies.

👍 If you make a PR, i'm sure people would love you.

The only stuff I can find about the terminal so far is stuff involving custom functions that call out to xclip or some other external plugin. This might be interesting to look at, though. The wiki seems mildly useful. And lastly, as further research, this answer which gives a nice useful hint as to how yanking behavior changes from emacs 24 to emacs 25 (notably that x-get-selection is obsolete in 25.1 and a new method gui-get-primary-selection, deriving from gui-get-selection becomes available)

Well, color my surprised. I have tried defining interprogram-cut-function and interprogram-paste-function myself and couldn't get it to work. I report it works with those definitions in the Arch wiki: (on Linux, with xclip installed in the system)

(unless window-system
  (when (getenv "DISPLAY")
    (defun xclip-cut-function (text &optional push)
      (with-temp-buffer
    (insert text)
    (call-process-region (point-min) (point-max) "xclip" nil 0 nil "-i" "-selection" "clipboard")))
    (defun xclip-paste-function()
      (let ((xclip-output (shell-command-to-string "xclip -o -selection clipboard")))
    (unless (string= (car kill-ring) xclip-output)
      xclip-output )))
    (setq interprogram-cut-function 'xclip-cut-function)
    (setq interprogram-paste-function 'xclip-paste-function)
    ))

Looking forward to see other working configs in other SOs, to bundle them in a layer.

#3064 may as well be included here (instead of in spacemacs layer as I suggested there).

I have some custom elisp code that does just this and would be happy to make a pull request to fix this. It works across remote machines using xsel, and also works gracefully inside tmux when reattaching from different machines.

Where would be the appropriate place to put such code for custom spacemacs layer?

[viccuad]

I'm personally glad that you are willing to share that code :), many thanks.

From what I know, You can use the configuration-layer/create-layer command from the contributing docs:
https://github.com/syl20bnr/spacemacs/blob/master/CONTRIBUTING.org#contributing-a-layer

This will create a all the needed file templates. For the layer structure, the read is:
https://github.com/syl20bnr/spacemacs/blob/master/doc/LAYERS.org

[cweill]

Thanks, I'll put a layer together. Which spacemacs/layers/ directory should this go under?

[wilhelmy]

Any updates on this?

Looking forward to see it merged eventually.

[mgsloan]

👍 I want convenient access to this too

[cweill]

I've just updated the PR to resolve the comments. PTAL.

[cweill]

This post on hacker news today is relevant to this topic. Maybe it will be useful for someone else here.

[syl20bnr]

Oops wrongly closed it.
Thank you @cweill, merged in develop branch.

[cweill]

@syl20bnr: My pleasure. Thank you for your review.

[NightMachinery]

Any way to make this work on macOS? I have xclip installed, but it doesn't work.

[NightMachinery]

@syl20bnr https://github.com/joddie/osx-clipboard-mode works great. I think it should be added to the osx layer.

[suonlight]

@NightMachinary, @syl20bnr : I had a PR to add osx-clipboard-mode to osx layer: #11215

[wilhelmy]

I think the correct OS X commands to use instead of xclip (which is X11 specific) are pbcopy and pbpaste, there's no need for a separate mode.

Edit: just my 2 cents, in the spirit of code deduplication. I don't actually use OS X, so I don't really care that much.

[NightMachinery]

The mode makes copy-paste just wor. Using those commands is very cumbersome. The mode is just a wrapper around them anyways.

Is it possible to have this layer support cygwin terminal like https://github.com/ArthurTu/cygwin-terminal-clipboard
