Quickstart

This is the fastest path from zero to a working algo program.

What algo is

algo is a competitive programming language that compiles to readable C++17.

The workflow is:

1. Write input.alg
2. Optionally run ./algo format input.alg
3. Run ./algo compile input.alg -o output.cpp
4. Compile the generated C++ with g++
5. Run or submit the result

Prerequisites

• A POSIX shell for the ./algo wrapper
• JDK 17 or newer
• g++ with C++17 support

On Ubuntu or Debian:

sudo apt install openjdk-17-jdk g++

Get the repo

git clone https://github.com/jiupr/algo.git
cd algo

Compile your first program

Create aplusb.alg:

input:
    a, b: int
println a + b

Compile it:

./algo format aplusb.alg -o aplusb.alg
./algo compile aplusb.alg -o aplusb.cpp
g++ -std=c++17 -O2 aplusb.cpp -o aplusb

Run it:

echo "3 4" | ./aplusb

Output:

7
