Unison.WatchKind

Description

A "watch kind" is the slug that comes before a ">" in a Unison file:

foo> bar = baz

In this example, the watch kind is "foo".

Synopsis

type WatchKind = String
pattern RegularWatch :: (Eq a, IsString a) => a
pattern TestWatch :: (Eq a, IsString a) => a
pattern RunWatch :: (Eq a, IsString a) => a
watchKindShouldBeStoredInDatabase :: Maybe WatchKind -> Bool

Documentation

type WatchKind = String Source #

pattern RegularWatch :: (Eq a, IsString a) => a Source #

A non-test watch, such as > 3 + 4

pattern TestWatch :: (Eq a, IsString a) => a Source #

A named test watch, such as

test> x = expect (1 == 1)

Note: currently test watches don't need to be named by the user, but that "feature" will be removed soon.

pattern RunWatch :: (Eq a, IsString a) => a Source #

A "run" watch, such as

run> do printLine "hello"

Unlike a regular watch, a run watch expects an expression of type '{IO, Exception} a, forces it (running its side effects), and is never cached — it re-evaluates on every save.
