vim : how to write to another file my lines yanked?

Question

I can do it with marks for exemple

But what is the syntaxt with yanked lines ?

Answer 1

Hard Way

You can call vim functions in command mode.
The command below will write yanked lines to /tmp/myFile.

:call writefile(split(getreg('"'), '\n'), '/tmp/myFile')

Note: Yanked lines are in unnamed register ("", type :help registers for help).

Easy Way

Why not do it visually. Just 3 basic commands everyone can understand:

• :tabe -- open new tab
• p -- paste to buffer
• :w /tmp/myFile.txt -- save file

Answer 2

You could use :redir (using register r):

:redir! > /tmp/myFile | silent echon @r | redir END

If you wanted to append you could use redir >> /tmp/myFile (note: no ! here, as "overwrite if exists" wouldn't make sense).

Answer 3

The other answers use special commands like :redir or writefile() to write to a new file. The most direct way is through opening a buffer for the file. This way, you can use the ordinary p / :put. As a bonus, the file stays in the buffer list, so it's easy to recall / edit later.

:split /tmp/myFile | put! | write | bdelete

or shortened:

:sp /tmp/myFile|pu!|w|bd
