Code Formatting

Bleep provides a unified fmt command that formats both Scala and Java source files in your project.

Basic Usage

# Format all source files
bleep fmt

# Check formatting without making changes (useful for CI)
bleep fmt --check

Scala Formatting

Bleep uses scalafmt for Scala code formatting.

Configuration is done via .scalafmt.conf in your build directory. If no config exists, bleep creates a default one.

For full configuration options, see the scalafmt documentation.

Example .scalafmt.conf:

version = 3.8.6
maxColumn = 120
runner.dialect = scala3

Java Formatting

Bleep uses google-java-format for Java code formatting.

Configuration is optional via .javafmt.conf in your build directory. If no config file exists, defaults are used.

Configuration Properties

Property	Type	Default	Description
enabled	boolean	true	Whether Java formatting is enabled
version	string	1.33.0	Version of google-java-format to use
style	string	google	Formatting style: google (2-space indent) or aosp (4-space indent)
skipSortingImports	boolean	false	Don't sort import statements
skipRemovingUnusedImports	boolean	false	Keep unused import statements
fixImportsOnly	boolean	false	Only fix imports, don't reformat code
skipReflowingLongStrings	boolean	false	Don't reformat long strings
skipJavadocFormatting	boolean	false	Don't reformat Javadoc comments
excludePaths	list	[]	Glob patterns for files to exclude

Example .javafmt.conf:

version = 1.33.0
style = aosp

# Skip Javadoc formatting
skipJavadocFormatting = true

# Exclude generated files
excludePaths = ["glob:**/generated/**", "glob:**/build/**"]

Notes

• Line length is fixed at 100 characters (google-java-format design decision)
• Indentation is fixed per style (2-space for Google, 4-space for AOSP)
