purescript v0.10.2 Release Notes

Release Date: 2016-11-07 // over 7 years ago

  • Major Changes

    Type-directed search (@kRITZCREEK)

    This extends the typed holes error messages to include suggested replacements for a typed hole, by using type subsumption to determine which identifiers in scope are appropriate replacements.

    A blog post will accompany this feature soon.

    📦 psc-package (@paf31)

    📦 This is an experimental package manager for PureScript packages. It supports the following commands:

    • 📦 init - create a new project using the package set for the current compiler version
    • ⚡️ update - sync the local package collection with the package set
    • 📦 install - install a specific package from the current set and add it to the package config
    • 🏗 build - run psc on any active packages
    • 📦 sources - list source globs for active package versions
    • dependencies - list transitive dependencies of the current project

    For example:

    $ psc-package init
$ psc-package install transformers
$ psc-package build

    📦 Eventually, psc-package might replace the use of Bower, but that will require support from tools like Pulp. For now, package authors should continue to publish packages using Bower and Pursuit.

    Data.Generic.Rep.Generic Deriving (@paf31)

    👀 This is an alternative generic programming implementation based on GHC.Generics. It should allow deriving of more interesting classes, such as Semigroup. See the purescript-generics-rep package for examples.
