I'm curious if there is a recommended way to implement lookahead in Ragel? Are
there any built in constructs or must it be done via external control
structures?
For example, I have a grammar:
FOO = 'foo' ' '+ BAR BAZ >execute_once;
BAR = alpha+ ('.' alpha+)*;
BAZ = ' '* '.' ' '* newline;
If the input is "foo bar.baz.\n", is there any way to know when Ragel has
finished with bar.baz for sure?
Thanks,
Rich
