Yate supports the insertion of capture groups where the inserted text is converted entirely to lower or upper case alphabetic characters. These sequences are supported in the regular expression replace template.
The $number and ${name} forms can specify an L or U character immediately after the $ character.
Examples:
- $U3
Insert capture group 3 entirely in upper case.
- $L0
Insert capture group 0, (the entire matched sequence), entirely in lower case.
- $L{test}
Insert the capture group named test entirely in lower case. Named capture groups are only supported on macOS 10.13 or higher.
