I was editing some code today in eclipse (yeah, I know, I should be using vim, but I got used to it for django projects).
But a fellow coder apparently did use vim. And had his settings to tab meaning an actual tab, whilst my eclipse settings turn a tab stroke into four spaces.
So hijinks totally ensued!
But it was an easy fix: I used the regular expression replacemente option and replaced every occurrence of four spaces with \t
So, there's that.
