# Regular Expression Replace Template Format

Note that in addition to the standard metacharacters described in the table, Yate supports \V# sequences via a prescan to insert the contents of a Variable. The contents of the variable are escaped to ensure that they do not interfere with any of the standard sequences.

The replacement text may contain references to capture-group text from the find. References are of the form $n, where n is the number of the capture group.

Character | Descriptions
--- | ---
$n | The text of capture group n will be substituted for $n. n must be >= 0 and not greater than the number of capture groups. A $ not followed by a digit has no special meaning, and will appear in the substitution text as itself, a $.
\ | Treat the following character as a literal, suppressing any special meaning. Backslash escaping in substitution text is only required for '$' and '\', but may be used on any other character without bad effects.
