xrc
A minimal CLI to give your Rust some exercise.
xrc turns a coding-problem URL into a ready-to-solve Rust project: it scrapes
the problem page, writes a clean cargo project with the statement, constraints,
and sample tests already wired up, and gets out of your way so you can focus on
the fun part: solving it. It also tracks your progress as you go.
Install
With cargo:
cargo install xrc
Or, if you live in the Python world, grab the prebuilt binary from PyPI:
pip install xrc # or: uv tool install xrc
Pull a problem
Point xrc at a problem you want to work on:
xrc pull https://dmoj.ca/problem/aplusb
xrc pull https://leetcode.com/problems/two-sum/
This creates a self-contained project under exercises/:
exercises/
└── a_plus_b/
├── Cargo.toml
├── src/
└── tests/
The problem statement lives right in the source as comments, and the sample cases are already turned into tests. Open it up and start writing your solution.
Supported sites today: dmoj.ca and leetcode.com.
Check your progress
When you think you have it, let xrc run the tests for every exercise and keep
score:
xrc check
Solved problems are remembered, so check skips them next time and only runs
what's left. A few flags for when you need them:
xrc check --verbose # show the full build and test output
xrc check --recheck # re-run everything, even already-solved problems
Your progress is saved in exercises/.xrc_progress.json, so you can pick up
right where you left off.
