4.20 Option for parenthesis matching

Brief: Control the style of matching delimiters produced by show-paren-mode.

Symbol: modus-themes-paren-match (‘choice’ type, list of properties)

Possible values are expressed as a list of properties (default is nil or an empty list). The list can include any of the following symbols:

The default (a nil value or an empty list) is a subtle background color.

The bold property adds a bold weight to the characters of the matching delimiters.

The intense property applies a more prominent background color to the delimiters.

The underline property draws a straight line under the affected text.

Combinations of any of those properties are expressed as a list, like in these examples:

(bold)
(underline intense)
(bold intense underline)

The order in which the properties are set is not significant.

In user configuration files the form may look like this:

(setq modus-themes-paren-match '(bold intense))

This customization variable affects the built-in show-paren-mode and the ‘smartparens’ package.
