Submit a challenge

You can submit a new challenge by running the command programming-challenges generate challenge --challenge="<your-challenge-name>" --github-user="<your-github-user>"

After running this command, a new folder will be created inside the challenges folder.

You can start editing the test folder of the challenge with corresponding input.txt and output.txt also don't forget to update README.md with appropriate exercise statement, to explain what is intended for this challenge.

Submit a solution

You can submit a new solution by running the command programming-challenges generate solution --challenge="<name>" --github-user="<your-github-user>" --language="<your-favorite-language>" --solution="<your-solution>".

After running this command, a new folder will be created inside the solutions folder of the challenge.

Start writing some code, inside the solution file with your favorite programming language, you will get the input thanks to STDIN, and you should output what is intended to STDOUT.

Before submitting the solution, make sure it passes all the tests by running programming-challenges run test --affected.

Add a programming language

You can add support for a new language, so you can solve the challenges with even more programming languages!

First create a new folder inside templates/docker with the file extension of the new programming language (e.g: js, cpp, etc.)
Inside this new folder create a Dockerfile, to compile and execute the solution
Create a new template inside templates/solution folder with the file extension of the new programming language, with the basic boilerplate to read from stdin and print to stdout the result
Every programming language should have at least one working solution for challenges/hello-world.

To generate the solution for the hello-world challenge with your new language, run the command programming-challenges generate solution --challenge="hello-world" --github-user="<your-github-user>" --language="<your-new-language>" --solution="function"

Before submitting the new programming language, make sure it passes all the tests by running programming-challenges run test --affected
