Changes for version 0.07
- Oh my head. Massive rewrite. The calltree was conceptually totally wrong. Changed call tree from a tree to a stack. No longer keep different branches around.
- Multiple quantifiers now work together. The following grammar now works:
- $grammar = match( series( capture(greedy(lit('x'),'s'),$first_callback), capture(greedy(lit('x'),'s'),$second_callback) ) );
- $grammar->('xxxxx')
- The first greedy will swallow the entire string, then release one character. This will allow second greedy to match on the last x, and the entire grammar passes.
- first capture eq 'xxxx'. second capture eq 'x'
- The commit function doesn't work with quantifiers yet. Changed the commit test to use a long series of lits instead. all tests now pass. However, there are some known bugs that don't have tests for them.
