history
Project history and usage
WartRemover is a Scala linting tool focused on compile-time detection of language features and idioms that a project wants to forbid. Its package-nerd identity is unusually direct: individual checks are called "warts", and users opt into sets of warts as errors or warnings in sbt, scalac, or the standalone command-line tool.
Project history
The public GitHub repository was created on January 5, 2013. Brian McKenna's 2013 write-up for WartRemover 0.4 described a rewrite from a linter for features he considered bad into a more flexible framework for lint rules over Scala compiler trees, with wrappers for macros, the command line, and the compiler plugin.
The project later standardized around the wartremover organization and the wartremover.org documentation site. Current documentation presents the sbt plugin as the normal entry point, while still documenting use as a command-line tool, a manually configured compiler plugin, and a macro-derived checker.
Adoption history
WartRemover occupies the compiler-plugin side of the Scala linting ecosystem. Scala Center's Scalafix documentation compares it with Scalafix, Scalastyle, and IntelliJ inspections, noting that WartRemover has more linter rules out of the box than Scalafix but does not automatically fix code.
How it is used
Typical use is to add the sbt plugin and then configure `wartremoverErrors` or `wartremoverWarnings` in `build.sbt`. Projects commonly enable a stable or custom subset of warts, suppress checks with annotations for exceptional cases, or exclude generated source directories.
Why package nerds care
For package managers, WartRemover represents the Scala compiler-plugin era of code-quality tooling: it is not just a formatter or external scanner, but a package that participates in compilation and can make disallowed constructs fail the build.
Timeline
- 2013-01-05: Public GitHub repository created.
- 2013: WartRemover 0.4 write-up describes the flexible rule/traverser design.
- 2020s: Documentation continues to support sbt, command-line, manual compiler-plugin, and macro-based usage.
Related projects
- Scalafix, Scalastyle, and IntelliJ Scala inspections cover adjacent Scala linting and refactoring workflows, while WartRemover's distinctive niche is compiler-driven configurable warts.
