Function compare_source_info

dev-scripts/src/commands.rs:150–190

Run the `alpm-pkgbuild srcinfo format` command on a PKGBUILD and compare its output with a given .SRCINFO file. If the generated and read [`SRCINFO`] representations do not match, the respective files `pkgbuild.json` and `srcinfo.json` are output to the current working directory and the function exits with an exit code of `1`. These files contain pretty-printed JSON, which accurately depicts the

(pkgbuild_path: PathBuf, srcinfo_path: PathBuf)
