Minify

bunpy build --minify app.py

The --minify flag strips:

• Blank lines and indentation (byte-safe - preserved inside strings)
• Single-line # comments
• Module-level and function-level docstrings

The minified source is embedded in the .pyz. The bytecode compiled from the minified source is functionally identical to the original.

Combining with –compile

bunpy build --compile --minify app.py -o dist/myapp

Minification reduces the embedded source size in the binary, not the binary size itself (the VM is the dominant factor).

When to use

Minification is primarily useful when distributing .pyz files where source confidentiality is a concern. It is not a security measure - the bytecode is still human-readable with a disassembler.
