Questions tagged [lint]

Lint is a C program checking developped in 1978 at the Bell labs and was used as a UNIX utility in 1979. There has now been several Lint-like programs (also code linters) that analyze source code written in possibly different languages, most notably:

  • Pylint: Python linter
  • JSHint: JavaScript linter with out-of-the-box support for renowned libraries
  • ESLint: JavaScript linter with support for ES6 and JSX
  • Findbugs: Java linter

Some linters support IDE integration which can allows to have real-time detection of possible bugs, and possibly automatic fixes.
