During May 2025, Efik722life enhanced the Orange-OpenSource/hurl repository by implementing header argument validation for curl commands within hurlfmt. Using Rust, they focused on improving the command-line interface’s parsing logic to enforce strict formatting rules for headers, requiring a colon or a semicolon for empty values. This approach proactively rejected malformed inputs at parse time, reducing runtime errors and increasing user reliability. Efik722life also developed comprehensive tests to cover both valid and invalid header formats, leveraging their skills in testing and parsing. The work contributed to the project’s ongoing efforts to improve CLI robustness and maintainability.
