Paul King updated GROOVY-11701:
-------------------------------
Description:
Java regex supports named-capturing groups which can still be accessed by
index. Groovy's shortcut syntax only supports the index access:
{code:groovy}
def regex = $/(?<day>\d{1,2})(?<sep>[-/])(?<month>\w{3})\k<sep>(?<year>\d+)/$
def m = '25-DEC-2025' =~ regex
assert m[0][1] == '25'
assert m[0][2] == '-'
assert m[0][3] == 'DEC'
assert m[0][-1] == '2025'
assert m.replaceAll('${month} ${day}, ${year}.') == 'DEC 25, 2025.'
{code}
This issue is to add named support in the normal Groovy way:
{code:groovy}
assert m[0].day == '25'
assert m[0].sep == '-'
assert m[0]['month'] == 'DEC'
assert m[0]['year'] == '2025'
{code}
