Hi,

If I understand it correctly you want to change something inside the "..." block and change the quotas to single '.

It can be done by this expression:

echo '"hello world" "hello again!"' | ./trre "\":'.+?:-\":'"

'-' '-'

So I substitute the text inside "" by symbol - using this expression ".+?:-" and simultaneously changing the surrounding quota.

Question mark means non-greedy mode.
