Getting Started

Basic Usage

Format a file (in-place):

qasmfmt input.qasm

Format multiple files:

qasmfmt *.qasm

Format from stdin:

cat input.qasm | qasmfmt

Check Mode

Check if files are already formatted (useful for CI):

qasmfmt --check input.qasm

Exit codes:

• 0: File is formatted
• 1: File needs formatting
• 2: Error (parse error, file not found, etc.)

qasmfmt --diff input.qasm
