Releases: purescript/purescript
v0.15.8
New features:
-
Generated documentation now supports dark mode (#4438 by @sometimes-i-send-pull-requests)
PureScript documentation has a new dark theme available. It will
automatically be used based on your browser or system's color scheme
preferences.
Bugfixes:
-
Outputs what label the type-error occurred on when types don't match (#4411 by @FredTheDino)
-
Account for typed holes when checking value declarations (#4437 by @purefunctor)
The compiler now takes into account typed holes when ordering value declarations
for type checking, allowing more top-level values to be suggested instead of
being limited by reverse lexicographical ordering.Given:
module Main where newtype K = K Int aRinku :: Int -> K aRinku = K bMaho :: K bMaho = ?help 0 cMuni :: Int -> K cMuni = K dRei :: Int -> K dRei _ = bMaho
Before:
Hole 'help' has the inferred type Int -> K You could substitute the hole with one of these values: Main.cMuni :: Int -> K Main.K :: Int -> KAfter:
Hole 'help' has the inferred type Int -> K You could substitute the hole with one of these values: Main.aRinku :: Int -> K Main.cMuni :: Int -> K Main.K :: Int -> K

New features:
-
Allow IDE module rebuilds eschewing the filesystem (#4399 by @i-am-the-slime)
This allows IDE clients to typecheck the module the user is currently typing in without modifying the output.
This allows for faster feedback cycles in editors and avoids producing a broken/outputbefore the user actually saves the file. -
Add
purs idedependency/imports filter (#4412 by @nwolverson)This allows IDE tooling to filter type searches according to the imports of a given module,
restricting to identifiers in scope. -
Shorten custom user-defined error message's prefix (#4418 by @i-am-the-slime)
Improves clarity and gets to the relevant information faster.
-
The compiler can now derive instances for more types and type classes (#4420 by @rhendric)
New type classes that the compiler can derive:
BifunctorBifoldableBitraversableContravariantProfunctor
Moreover, the compiler can also use these classes when deriving
Functor,Foldable, andTraversable, enabling more instances to be derived
whereas before such instances would need to be written manually.
