Code of conduct Apache-2.0 license named-regexp This library backportsnamed capture groupsfrom Java 7 to Java 5/6. Usage You can use the same constructs for named capture groups from Java 7 (i.e.,(?<name>patt), etc.), as in the following example: ...
JavaScript regex named group example Simple example code that demonstrates how to use named capture groups in JavaScript: const regex = /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/; const match = regex.exec('2023-06-14'); console.log(match.groups.year); console.log(match.g...
Greta doesn’t support named groups; instead, it uses the more standard approach of numbering them. So you should check your regex to "^(\\w+):(\\w+)" Then you access the first group as capture number 1 and the second as capture number 2, as in Perl, etc. As far as I know, ...
这也是为什么在使用 capture groups 的时候输出里老是有一个 groups === undefined 解构小技巧 值得注意的是, named group 其实也是 capture group, 只不过是特殊的 capture group, 所以下面的代码依然可以运行 constre=/(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/constmatch=re.exec('2020-...

The issue here is that resolve() will return None for any optional capture groups that aren't captured, but reverse() will use force_text() and convert it to the literal string 'None'. This causes an asymmetry between resolve() and reverse(). I think it's a better idea to treat thi...
