Berry 're.dump()'

[s-hadinger]

Description:

Berry added re.dump(pattern_compiled:bytes) -> nil, print a dump of the compiled pattern into the state-machine used by regex engine. This is only available if compiled with #define USE_BERRY_DEBUG

Example:

> import re
> var rb = re.compilebytes("a.*?b(z+)")
> print(rb)
bytes('1B0000000F0000000100000062030260FB7E00016162030260FB01627E02017A...')

> re.dump(rb)

 5: save 0
 7: char a
 9: rsplit 14 (3)
