Different behaviour for Cmd+C, Cmd+v, etc on Mac

[petethepig]

It allows you to copy/paste any text from/into the terminal.
I suggest it, since this is the default behaviour in Terminal.app on Mac.

Copy and paste doesn't work for Macs, at least in the way that everyone tries. No one will try Opt-C/V!

Now I'm confused. The isMac and ev.metaKey check is there to check for a mac's equivalent of Alt (which is Option, I think?). Why would that if statement affect the Command key? This change would also stop a whole range of key combinations from working.

Could either of you show me the raw event output for keydown of Cmd+[anything] in the browser? It should be event.ctrlKey.

[jagill]

The check for Cmd in mac is event.metaKey. Option is event.altKey. Ctrl is event.ctrlKey.

Here is Cmd-C:

Ah, okay. So command is considered meta (seriously unfamiliar with mac keyboards). Gotcha. Yeah, I'll add a better check that won't disrupt any other key combinations either. Thanks for checking.

[jagill]

Yeah, the mode key event attributes in mac are very non-intuitive.

[soumith]

@petethepig thanks for your patch, works great.

[jessetane]

@chjj would be nice to have this or something to its effect

See also PR #37. I'm not a Mac user, but assuming that Option+key on Mac should work like Alt+key on other systems, I think that one is preferable - this one appears to disable all Alt shortcuts on Macs.

I tried to support Cmd-C, Cmd-V on Mac using hidden textarea.
