Pseudo-Indent (two spaces) Multiple Lines

Question

Basically, I need to indent a block of R code. Unfortunately, vim's tab size is bigger than the two spaces that I'm using. Is it possible to accomplish this without hitting the space bar twice for every line I need to indent?

The motivation for this may be of note: I originally wrote the script in Rstudio before moving it to a server. Many indents just go away when I edit the server-side file with vim. However, if I transfer the file to my laptop (via winSCP) and open it in rstudio, all the indents look perfect!

Answer 1

First, you probably want to set tabstop and shiftwidth to 2 to have the indentation work as you want.

Now you want these settings applied only for the files with the filetype r, the best way to do that is to create a custom ftplugin. To do that you want to create the file ~/.vim/after/ftplugin/r.vim.

This file will be sourced when the filetype of a buffer is set to r and after the ftplugin which comes with Vim by default has been sourced (this way you don't loose the already existing settings).

In this file you can simply add:

setlocal tabstop=2
setlocal shiftwidth=2

Here you need to use setlocal instead of set to make sure that the settings will only apply to the current buffer and not to all buffers.

Some interesting related help topics:

• :h ftplugin
• :h :setlocal
• :h 'shiftwidth'
• :h 'tabstop'
