The slang "linter" originates from the specific product PC Lint, though there are many other such tools for various programming languages and coding standards.

The first linter was written by Stephen C. Johnson in 1978 while working in the Unix operating system at Bell Labs. After that, many other linters have appeared for different purposes and languages, not only C.

Tag usage example: .

Also include versions of the programming language, coding standard and tool where applicable.
