scalafmt

Code formatter for Scala. Configurations are stored in the .scalafmt.conf file. More information: https://scalameta.org/scalafmt.

• Reformat all .scala files in the current directory recursively:

scalafmt

• Reformat specific files or directories with a custom formatting configuration:

scalafmt --config {{path/to/.scalafmt.conf}} {{path/to/file_or_directory}} {{path/to/file_or_directory}} {{...}}

• Check if files are correctly formatted, returning 0 if all files respect the formatting style:

scalafmt --config {{path/to/.scalafmt.conf}} --test

• Exclude files or directories:

scalafmt --exclude {{path/to/file_or_directory}} {{...}}

• Format only files that were edited against the current Git branch:

scalafmt --config {{path/to/.scalafmt.conf}} --mode diff
