How to paste under terminal emacs?

How to paste under terminal emacs?

[Shiyao Ma]

Hi,


To be specific, I am under iTerm2 using ssh to a linux box.

I often paste stuff using command+v to terminal emacs.

However, looks like emacs takes the paste char by char, which significantly
makes the paste unnecessarily slow.

How to make emacs take the paste as a whole?

Like the way `:set paste' in vim.


Regards.

Does iTerm2 implement xterm’s [bracketed paste][1] protocol?

[1]: http://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h2-Bracketed-Paste-Mode

Emacs could watch for an ESC [ 2 0 0 ~ sequence and, when it sees one,
stop redrawing until ESC [ 2 0 1 ~ is seen.

This is already implemented in recent-enough Emacs, BTW.

I found a sample snippet here:
https://github.com/hchbaw/bracketed-paste.el/blob/master/bracketed-paste.el

Dunno what do you mean by "alredy implemented in Emacs".

This is more a terminal related stuff.

That recent Emacsen incorporate code akin to bracketed-paste.el, and they
use it without you even noticing it.

OK, I checked and I was partly lying: it's only supported in the
upcoming 25.1.  Excerpt from the NEWS file:

    * Editing Changes in Emacs 25.1
    [...]
    ** Emacs now uses "bracketed paste mode" on text terminals that support it.
    Bracketed paste mode causes text terminals to wrap pasted text in special
    escape sequences that allow Emacs to tell the difference between text
    you type and text you paste from other applications.  Emacs then
    avoids interpreting each character in the pasted text as it does with
    keyboard input, which results in a paste experience similar to that
    under a window system, and significant performance improvements when
    pasting large amounts of text.
    
    Bracketed paste mode is disabled by default, so Emacs automatically
    enables it at startup if the terminal supports it.
