mars-rover

Nix is a requirement for dependency management

Live edit Mars rovers!

Ensure mars-rover.hs is executable with:

chmod u+x mars-rover.hs

Now run it with:

./mars-rover.hs

  • On first run Nix will install all dependencies then run the file which will print the result of running tests.
  • You can now edit the file mars-rover.hs and the tests will automatically re-run in the terminal every time you save the file.

Compile binary and parse input files

Open a Nix shell with the required dependencies:

nix-shell -p "haskellPackages.ghcWithPackages (p: [p.hspec p.hspec-megaparsec p.megaparsec])"
Then compile with:

ghc mars-rover.hs

  • A binary (mars-rover) will be created.
  • If you pass the file path as an arg to the binary it will parse and run the simulation.
Parse and run the example file with:

./mars-rover $(readlink -f example.txt)

Output should look like:

(4, 4, E)
(0, 4, W) Lost
(2, 3, W)
(1, 0, S) Lost
