PureScript v0.10.2 发布了，PureScript 是个小巧而强大的静态类型语言，可以编译成 JavaScript。PureScript 主要是由 Haskell 和 PureScript 编写的。

该版本更新内容如下：

主要变化

类型导向搜索 (@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 的派生 (@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.
