What I'm looking for is to get at the hash structure described in Rx: A Regex Debugger for Perl, it is the hash version of this printout
$ perl -Mre=debug -e " /larry.wall+!/ "
Compiling REx "larry.wall+!"
Final program:
1: EXACT <larry> (4)
4: REG_ANY (5)
5: EXACT <wal> (7)
7: PLUS (10)
8: EXACT <l> (0)
10: EXACT <!> (12)
12: END (0)
anchored "larry" at 0 floating "l!" at 9..2147483647 (checking anchore
+d) minlen 11
Freeing REx: "larry.wall+!"
Rx-0.53/dump_regexes.pl requires recompiling perl (and I haven't tried it yet), so any options besides parsing the output of re=debug ?
