The scalafmt
command is used in Scala programming for source code formatting. It is a tool that automatically formats Scala code according to a given set of formatting rules.
By executing the scalafmt
command on a Scala codebase, the tool analyzes the code and rearranges it to adhere to a predefined coding style. This helps to maintain consistent formatting and improve code readability. scalafmt
works by parsing the Scala code and then performing a series of transformations to format it.
Some key features of scalafmt
include:
-
Configurable rules: It allows customization of formatting rules according to a team or project's coding standards.
-
Integration:
scalafmt
can be integrated into popular development tools like build systems (sbt, Maven, Gradle), IDEs (IntelliJ, Visual Studio Code), and editors (Vim, Emacs). -
Incremental formatting:
scalafmt
can format only the changed parts of a codebase, which makes it suitable for use in continuous integration pipelines to apply formatting on code commits.
The scalafmt
command usually takes the input source file or directory as an argument and formats the code following the specified rules. By properly formatting the code, scalafmt
helps to enforce a consistent coding style and improves code maintainability.
