PostCSS Inherit Parser

postcss-inherit-parser is a specialized parser for PostCSS, designed to interpret a custom CSS syntax that facilitates "inherit" declarations, specifically in conjunction with the `postcss-inherit` plugin. This parser enables the processing of CSS where rules can leverage inheritance from other selectors, including those with pseudo-classes, as exemplified by syntax like `.a { inherit: .b:before; }`. The package, currently at version 0.2.0, was last published approximately 8 years ago, suggesting it is no longer actively maintained. Its core functionality is to provide the Abstract Syntax Tree (AST) representation for this non-standard inheritance syntax, allowing subsequent PostCSS plugins to apply transformation logic. A key feature is the configurable `propertyRegExp` option, which allows consumers to define custom keywords for inheritance, such as `extend` instead of `inherit`. Given its age and low version, developers should be aware of potential compatibility issues with newer Node.js or PostCSS versions.
