Are the examples all actual outputs of the program? It's entirely possible that my understanding of the grammar is off, but it looks like these examples are wrong:

$ echo 'cat dog' | trre 'c:bat|d:hog' bat hog

$ echo '' | trre ':a*' # <- do NOT do this dog

$ echo '' | trre ':(repeat-10-times){10}' dog

The second line actually is an output. I've modified the README. The last example is a typo. Fixed. Thanks!

And the first one? Wouldn't the output be

batat hogog

[c0nstantine]

Can't reproduce.

I have the following:

> echo 'cat dog' | ./trre 'c:bat|d:hog'

bat hog

[robertlutece]

it reads like '(c:b)at|(d:h)og' and not 'c:(bat)|d:(hog)'
