Is Match Formatter

Use the Is Match Formatter to evaluate regular expressions to control the output. The Is Match Formatter is not included by default. You can add it to the Formatters in the Smart Format Settings.

Note

In the options part of the formatter, not all regular expression characters are valid. For example, curly braces and parentheses aren’t supported because the same parser is used for all other extensions.
