Exercism Purescript track setup

https://exercism.org/tracks/purescript

The goal

• Uses local spago and purescript libraries.
• Prevents the downloading of equal packages in every exercise folder.

The usage

• Requirements: exercism-cli https://exercism.org/cli-walkthrough.
• Install npm dependencies npm i
• Add an exercise with npm run addex <exercise> (for example, pangram)
• Go in the exercise folder cd exercises/<exercise>
• Run test npm test

Npm scripts

setup

• setup-dirs - creates ./.spago and ./output folders
• setup-link - links <exercism-workspace>/purescript to ./exercises

exercise

• addex <exercise> consists of other two npm scripts:
• ex-download <exercise> - downloads the exercise into exericsm workspace folder (in this case, <exercism-workspace>/purescript/<exercise>)
• ex-link <exercise> - links ./exercises/<exercise>/{.spago,output} to ./.spago and ./output folders.

vscode

• vscode-workspace creates (if not exists) vscode workspace file in ./.vscode/ with ./exercises/* sub-folders, updates settings.purescript.pursExe to ./node_modules/.bin/purs.

idea

• open the . folder
