Unobtrusive highlighting of trailing whitespace in Vim

Sunday, September 13, 2009

Many programmers highlight trailing whitespace red to expose that unnecessary gunk that is otherwise hard to spot. I did not much care about trailing whitespace, it was never a problem for me, though now the distributed version control systems tend to complain about this.

Highlighting the trailing whitespace is effective but has this unwanted side-effect of a red thing appearing under the cursor when typing space at the end of line (most of the time I type space at the end of line it seems).

This set of commands will only highlight the trailing whitespace on opening the buffer and leaving the insert mode. Inspired by the Vim tip wiki.
