Test and submit solutions to BOJ (Baekjoon Online Judge) problems.
Defaults are geared towards Rust solutions, but non-Rust usage is supported as well.
A stable Rust toolchain.
cargo install cargo-boj
The default usage of
submit commands assume that
cargo boj is being run at the crate root with either
src/bin/main.rs being the solution file.
Logging in to BOJ with ID and password cannot be automated because it is protected with reCaptcha. So, the users are expected to log in on their own browser first, and then copy relevant cookies into
$ cargo boj login
