Revision history for property-matchers

0.7

• Use the Show constraint on equals to produce a better printed actual, not just expected.

0.6

• Add Show constraint to equals and other comparison properties to improve error messages in cases where rtti-derived printing is not as good.

0.5

• Add notEquals property.
• Delete atIndex, endingWith, and startingWith. These can easily be replaced by prisms via match, like with match (ix k), match _head, and match _last.
• Delete bool in favor of equals True.
• Export Getting in case it's useful.
• Add some doctests.
• Update docs.

0.4

• Fix allOf1 which would fail on a non-empty input, instead of the opposite
• Add anyOf
• Rename allTrue to checkAll

0.3

• Add fails function, for asserting that an exception is thrown
• Replace propful with alignExact
• Add alignLax generalizing alignExact
• Add elem
• Add fixity for :=> to be compatible with ?
• Add comparisons other than equals

0.2

• Add bool function
• Add hspec + smallcheck test suite
• Add branch for non-backtracking disjunction of properties
• Monomorphize fail, succeed, assess, branch for ease of use in hspec
• Rename PropertyFailed exception type to PropertyException to recognize the new case for branch
• Add type Assertion = IO ()
• Add a few pragmas
• Reorder PropertyMatchers module for intelligibility

0.1

• Rename to property-matchers
• Rename kth to atIndex
• Change error message formatting for predicate failure

predicate-transformers 0.17.0.0 -- 2024-10-13

• Rename multiple functions to shorter names with the intent that predicate-transformers be imported qualified. In particular also renamed to and, otherHand renamed to or, etc.
• Delete lens and mtl dependencies.
• Delete soleElementOf, for lack of use in favor of match.
• Rename Predicatory to Boolish for ease of reading.
• Delete Exceptional class, folding it into the newly renamed Boolish.
• Delete predJust, predLeft, and predRight in favor of match uses.

predicate-transformers 0.16.0.0 -- 2024-10-13

• Add predicate failure error messages that include the actual value under test and a message explaining what was expected.
• Rename just, left, and right to predJust, predLeft, predRight

predicate-transformers 0.15.0.0 -- 2024-08-23

• Change ? to right associative so that it works with ..

predicate-transformers 0.14.0.0 -- 2024-08-23

• Add ? back in as a useful operator to work with &; & can be used as a predicate applicator, and ? can be used as a predicate transformer applicator, allowing for a form of infix binary application like x & f ? y = f x y.
• Add match back in as a type-restricted alias for soleElementOf.

predicate-transformers 0.13.0.0 -- 2024-07-23

• Remove ?

predicate-transformers 0.12.0.0 -- 2024-07-23

• Rename sole to soleElement
• Add ?, an infix function application operator with lower precedence than !.
• Add satAll = foldr also continue.

predicate-transformers 0.11.0.0 -- 2024-07-21

• Add documentation.
• Rename onlyContains to sole. Add soleOf, generalizing over Folds. soleOf is likely a better replacement for match than allOf1 was.
• Exchange INLINABLE pragmas for -fexpose-all-unfoldings.
• Implement traceFailFunShow.
• Change Exceptional's method assess to make it possible to implement for functional predicates, and delete traceFailFun, now redundant.

predicate-transformers 0.10.0.0 -- 2024-07-21

• Rename oneOfTwo to otherHand, for easier reading.
• Set also and otherHand precedences to those of && and || respectively. That makes them work better with the precedence of !, allowing easier composition.
• Rename only to onlyContains, for easier reading and to avoid a name conflict with Control.Lens.only.
• Set ! precedence to be equal to that of ..
• Add equals predicate.
• Delete match. allOf1 does the same thing more generally, with Fold instead of Prism.
• Make otherHand stop catching async exceptions. Otherwise a thread being killed may appear as a predicate failure.

predicate-transformers 0.9.0.0 -- 2024-07-21

• Add instance Predicatory (e -> a). This will allow for adding extra parameters to predicates, making it easier to compose them; maybe these are called "functional predicates".
• Added traceFailFun. This version of traceFail works on functional predicates.
• Tupling sugar renamed from ==> to :=>, to allow it to be a pattern synonym.
• Minor code style changes.

predicate-transformers 0.1.0.0 -- 2019-10-05

• First version. Released on an unsuspecting world.
