nixf-diagnose is a CLI wrapper for nixf-tidy with fancy diagnostic output. It provides enhanced error reporting and variable lookup analysis for your source files.
To use nixf-diagnose, you need to provide the path to the input source file.
Optionally, you can specify the path to the nixf-tidy executable and enable or disable variable lookup analysis.
By default, the nixf-tidy command will be looked up in your $PATH.
You can install it by installing the nixf package from nixpkgs (no need to install the full LSP!).
./nixf-diagnose --input <path_to_source_file> [--nixf-tidy-path <path_to_nixf_tidy>] [--variable-lookup <true|false>]Example output:
Error: duplicated attrname `a`
