Leetr

A CLI tool for setting up local LeetCode projects.

Installation

Using cargo

cargo install leetr

From source

# Clone the repository
git clone https://github.com/pophilpo/leetr

# Navigate into the project directory
cd leetr

# Build the project in release mode
cargo build --release

# Copy the binary to your bin directory (adjust the path if necessary)
sudo cp target/release/leetr /usr/local/bin

Usage

To use leetr, pass the URL of the LeetCode problem or its title and the language of your choice (python/rust) to the tool.

Arguments

• -d, --dir Creates a directory with a custom name for the problem, otherwise uses problem name
• -l, --lang Programming language used to setup the project [default: rust]
• -h, --help Print help

Default language

By default the language used is rust, but if you want to change it and use leetr without passing the --lang argument everytime you can create an env-var LEETR_DEFAULT_LANGUAGE

export LEETR_DEFAULT_LANGUAGE="python"

Using the -l/--lang argument will overrule this env-var.

Examples

This command generates a Python 3 project with the following structure:

• A two_sum/README.md file describing the problem.
• A two_sum/main.py file containing the initial problem code

leetr two-sum -l python

This command generates a Rust project with a custom name and the following structure:

• A my_project/README.md file describing the problem.
• A my_project/main.rs file containing the initial problem code

leetr https://leetcode.com/problems/two-sum/description -l rust -d my_project
