This checking is performed by a static code analysis tool called a linter. A code formatter, however, is a tool concerned with formatting source code so that it strictly adheres to a pre-configured set of rules. A linter will typically report violations, but it's usually up to the programmer to fix the problem, while a code formatter tends to apply its rules directly to the source code, thus correcting formatting mistakes automatically. The task of creating a more consistent code style in a project usually necessitates the introduction of a separate linting and formatting tools, but in some cases, a single tool will be capable of addressing both concerns.
