Hi
ATM I need plenty of hacks to be able to dynamically see the OP-Tree of a Regex at runtime cause
use re 'debug' emits the code of a regex at compile time to STDERR.
lanx@nc10-ubuntu:~$ perl
use re 'debug';
my $a=qr/(?<C>1)(?<D>2)(3)(?<A>4)/;
Compiling REx "(?<C>1)(?<D>2)(3)(?<A>4)"
Final program:
1: OPEN1 'C' (3)
3: EXACT <1> (5)
5: CLOSE1 'C' (7)
7: OPEN2 'D' (9)
9: EXACT <2> (11)
11: CLOSE2 'D' (13)
13: OPEN3 (15)
15: EXACT <3> (17)
17: CLOSE3 (19)
19: OPEN4 'A' (21)
21: EXACT <4> (23)
23: CLOSE4 'A' (25)
25: END (0)
anchored "1234" at 0 (checking anchored) minlen 4
Freeing REx: "(?<C>1)(?<D>2)(3)(?<A>4)"
In Re^2: Is there really no @LAST_MATCH_START equivalent for named capture groups? I need to recompile a new regex within an eval while redirecting STDERR to a variable...
Thats hacky and cumbersome!
Is there any simpler or cleaner way to achieve this?
