I suck at regex. But the fact that Eclipse leaves trailing whitespace everywhere is pretty fucking annoying. Although, this will apparently be solved in 3.3, that's still a month or so away (IIRC). Anyways, while I normally just use a $ regex search (whitespace switches don't like working in Eclipse's find dialog) to repeatedly weed out the bastards, today, I came across a more robust expression. Here goes:
Find: [\t ]+(?:(\n)|$)
Replace: $1
and Jesus wept (with joy).
