purescript-ps-cst

Objectives:

• types are a copy of purescript-cst (on hackage, github)
• don't aim to be a complete copy of purescript-cst (because these types were created for parsing, not printing), but support 80% of most used printing functionality
• parentheses are added automatically, there is no need to use ExprParens or TypeParens (which are added by purescript parser on parsing phase)

TODO:

• use https://pursuit.purescript.org/packages/purescript-optparse/3.0.0/docs/Text.PrettyPrint.Leijen instead of Boxes to allow for example:

  • configuring width of printed document
  • conditionally print Type's in one line or in multiple lines based on expected line width (and not based on context as it is now)

• support comments

• calculate imports automatically based on Declarations

• finish pending tests in spec directory

• provide configuration for printing function (e.g. allow to use ∀ instead of forall)
