cleanup-whitespace.py

cleanup-whitespace.py is a Python script that cleans up common whitespace inconsistencies in Java files.

What It Does

The script performs the following cleanup operations:

1. Removes consecutive blank lines - Maximum of 1 blank line allowed between code sections
2. Removes trailing whitespace - Strips whitespace from the end of all lines
3. Removes blank lines before final closing brace - Ensures files end cleanly with }
4. Ensures proper file endings - Files end with } with no trailing newline

Usage

Clean the entire Juneau codebase

cd /Users/james.bognar/git/juneau
python3 scripts/cleanup-whitespace.py

Clean a specific directory

python3 scripts/cleanup-whitespace.py juneau-core/juneau-marshall

When to Use

Use this script when:

• Preparing code for commit
• Fixing whitespace inconsistencies
• Ensuring consistent file formatting

Requirements

• Python 3.6 or higher
• No external Python dependencies (uses only standard library)

Notes

• The script only modifies .java files
• Files are modified in-place
• Always review changes with git diff before committing
