• Line Matcher for text data, like grep but more opinionated.

Usage

• match vars.conf TEMPLATE < INPUT_FILE

File formats

• vars.conf (example)

ANY = \S+
NUM = \d+

• template.conf (example, any text that will match with INPUT_FILE)

The quick brown ANY jumps over the lazy dog NUM times

• INPUT_FILE (any text that will match with TEMPLATE)

The quick brown fox jumps over the lazy dog 100 times
The quick brown fox jumps over the lazy dog X times
The quick brown cow jumps over the lazy dog 100 times
The quick brown cow jumps over the lazy dog 100

Output for above example

% ./match examples/vars.conf examples/template.conf < examples/input.txt

  • abc(TEXT) and abc*(VARS)

• No backtracking, when there is two route a->B->c, and a->Z->y

  • if B is chosen and c does not match, program will not attempt to backtrack to c->Z->y
