[email protected] - run the macro in register 'a' ten times

Copying text from one VIM instance to another

Tagged vim, paste, indentation  Languages 

Copying and pasting text between two VIM instances messes up the indentation in a very annoying way. To avoid this problem first run this VIM command:

:set paste

After you have pasted the code, run this command:

:set nopaste

A proper vim setup

Tagged vim  Languages bash

Out-of-the-box vim setup is good, but with a few tweaks it gets much better. Install the full version instead of the minimal and also exuberant ctags, which are great for programmers using vim. They let you navigate in the source code like you do in a full fledged IDE.

sudo apt-get install vim exuberant-ctags

Then place the content below into your ~/.vimrc file.
