Code Linter

A simple code linter for Rust that detects common issues like unused variables and improper naming conventions.

Features

• Detects unused variables.
• Ensures functions follow snake_case naming conventions.
• Warns about high cyclomatic complexity in loops and nested if statements.
• Identifies dead code (unused functions).
• Provides JSON output for easy integration with CI/CD tools.
• Automatically fixes some linting issues using rustfmt.
• Uses multi-threading to speed up linting for larger files.

How to Run

1. Clone the repository:

   git clone <repository_url>
   

2. Build and run the project:

   cargo run -- <file_to_lint.rs>
   

3. Lint a Rust file by specifying its path as a command-line argument.

4. To specify the output format (plain or JSON):

   cargo run -- <file_to_lint.rs> -o json
   

5. To automatically fix formatting issues using rustfmt:

   cargo run -- <file_to_lint.rs> --fix
