Enhancing PureScript's Pursuit

Harry Garrood

The problem

• A fair bit of reusable PureScript code exists
• We want to make it accessible and discoverable

What kind of questions do we want Pursuit to answer?

Pursuit now

• Haskell web application (Yesod)
• Small amount of JavaScript (!)

HTML documentation

• Package overview page
• Links to dependencies
• Source links via GitHub
• Package authors run a tool locally and upload

GitHub integration

• Authentication (OAuth)
• Displaying readme files
• Source links
• Backup

Interlude: Rows

type Person = { name :: String, age :: Int }

p :: Person    =>    p.name :: String

type Person = Prim.Object (name :: String, age :: Int)

log :: forall e. String -> Eff (console :: CONSOLE | e) Unit

Hoogle

• Store an intermediate form of data
• Generate Hoogle input files
• Fiddle to make it parseable by haskell-src-exts
• Use Hoogle library to create a database
• Regenerate periodically
