7.7. Regex Mask

Regex mask is a text pattern format based on regular expressions. It is supported wherever a glob or assembly mask is supported. Regex mask can be used to configure the following features:

7.7.1.¬†Syntax‚Äč

Regex mask should start with ^ and end with $ characters. The rest of the syntax follows the usual regular expression syntax.

7.7.2.¬†Behavior‚Äč

Regex mask case-sensitivity depends on a usage context. When it is used in place of a glob mask, the regex mask is case-sensitive. When it is used in place of an assembly mask, the regex mask is case-insensitive.
