Once logged in to GitHub, in the top right press Fork.
Continue through to make your own copy of this repo.
Now in your personal copy of this repo, click "Code" in the top right, then "Codespaces", then click + or "New Codespace".
Now you're in a codespace, follow the below instructions.
Run ./install.sh to get the ghci compiler ready.
This takes around 5 minutes to complete on first run, from then on it takes no time at all to run.
- Answer [P] or [Y] to any questions it asks you (yes).
- If it looks like it's not doing anything, you may need to press ENTER to proceed.
- Once it's finished, you'll see a smiley face and a lot of green text.
NOTE: When coming back to this, you don't need to create another new codespace! Simply click on the name of the Codespace you created before - it's likely to be the only one in the list. If ghci isn't working, try the Troubleshooting steps at the bottom. If that fails, run the install script again!
To access the console, enter ghci
To run a file, enter ghci filename.hs
To exit the console, enter CTRL+D
You may want to create a .hs file to store your functions in.
On the left, click on the 4 squares (extensions)
Search for Haskell
Then install the Haskell extension. This makes Haskell nicer to work with.
It should "just work", but if not, you may need to tell it we're using the GHCup compiler, and it can be found on bash. But you shouldn't need to do this.
If running ghci fails, you should run:
. /home/codespace/.ghcup/env
This tells codespaces where it's installed, so it should then work.
