Copy to clipboard functionality

[TyberiusPrime]

It would be nice if I could still copy to clipboard instead of just yaking within ipython notebook from the keyboard. Can't seem to find a keybinding for that.

[lambdalisue]

It would be nice for me as well but I don't know how.

[lambdalisue]

it seems impossible. most browser does not allow to access clipboard because of security reason.

[TyberiusPrime]

Yes, but if we manage to release ctrl-c back to it's default browser binding, we should have a regular copy event?

[lambdalisue]

Good point. I'll remove the line https://github.com/lambdalisue/jupyter-vim-binding/blob/master/nbextensions/vim_binding.js#L104

[TyberiusPrime]

I think something lower down is also hogging the shortcut :(

[lambdalisue]

It is a difficult topic. I don't have any compas to select which shortcut is necessary thus I just copied most of that from jupyter's default.

which one do you think "bad mapping"?

[TyberiusPrime]

All I know right now is that ctrl-c doesn't work for copy for me even if I remove that line. Ctrl-V in insert mode does work though - even though it works as visual selection in command mode.

[lambdalisue]

Hum.... In my case, C-V doesn't work as well. I'll check it

Probably we have to end up for enabling system clipboard. It won't work in CodeMirror's Vim mode. While this plugin rely on CodeMirror's Vim mode, it is not possible to enable the system clipboard.

Although we are vimmer, we have to use a mouse to copy and paste text... Really inconvenient :angry:

I think I found a compass https://github.com/LightTable/LightTable/issues/688

[lambdalisue]

Sigh. https://github.com/codemirror/CodeMirror/blob/master/keymap/vim.js#L1265

[TyberiusPrime]

I take it that's not just the input mode callback :(

[lambdalisue]

Anyway, this is a problem of CodeMirror so I close it.

[TyberiusPrime]

Not so fast with the closing, I found a way that works by disabling all ctrl-c binding, which then has the browser take over:

this.code_mirror.addKeyMap({"Ctrl-C": false});

[lambdalisue]

Well. It is good to know but while CodeMirror's default behavior disable Ctrl-C, I would like to follow that and that kind of trick should be performed by user.

But anyway, thanks to found the solution. I will add the tips to README.md later
