The '-g' flag is obsolete. Somehow it got into my new docs. The right way is to use '-ma' flags where '-m' is for matching the whole string and '-a' stands for all the outputs.

You got the idea correctly. E.g. to generate all strings of length 5 over alphabet 10 (and truncate to 10000) you can do:

echo '' | ./trre -am ':[a-c]{5}' | head -n 1000

The docs are fixed now. Thanks for pointing this out.

The infinite generators is something nice to have, I agree. Just didn't wrap my hand around how to do this in 'ergonomically' correct way.
