Pasting from cliboard in osx returns ^M instead of newline

Question

I'm having a problem with pasting on MacOS Sierra. When I copy text with newlines, I can paste it in a terminal without issue. e.g.: Text to be copied:

echo 'Foo'
echo 'Bar'

result from terminal (same in iTerm, Term using both bash and zsh):

[23:38:29] ~ $ echo 'Foo'
echo 'Bar'
Foo
Bar

result from vim within terminal

echo 'Foo'^Mecho 'Bar'^MFoo^MBar

As you see, the carriage return is interpreted as a literal string. I have tried in pastemode and fileformat=unix

My .vimrc can be found at https://github.com/zsoobhan/configs/blob/feature/osx/vimrc.

Any help is greatly appreciated

Answer 1

Basically when you paste using cmd + V, it is just throwing the content of the macOS clipboard at vim. It is just like typing each character that is in the clipboard literally into vim. That sometimes works, but often it doesn't. So the use is discouraged.

For this purpose there is the "* and "+ registers which use the system clipboard and paste the content of that into a native vim register. These are buggy on macOS, but well they seem to work in your case.

Also see help quotestart, help quoteplus and help clipboard

The other alternative is using pbpaste and pbcopy and use line filtering. When you .!pbpaste, the current line is the input and the output (that's signaled by the dot) of the external following command (that's signaled by the exclamation mark) used.

So you can use :.!pbpaste to paste the content.

And you can use :.!pbcopy to copy a single line. But the line vanishes if you do this, because pbcopy has no output. However you can do this: .!tee >(pbcopy)

Quoting from Bram:

I assume you are talking about the command line, or entering search. Yes, it's intentional that the line break does not work like pressing Enter. The idea is that you are pasting text, not a command. You are supposed to view the text before deciding to execute it. The thread that started it mentioned that the source of the text may give you something else than what you expected. In practice, what often happens is that you accidentally copy the wrong text and include the line break when that is not intended.

This has been recently been changed when bracketed paste support was added. You can disable bracketed paste mode by :set t_BE=
