• introduce matcher-combinators.config namespace to toggle use of ansi color codes and the new output abbreviation mode.
• [Experimental] add (matcher-combinators.config/enable-abbreviation!), an experimental feature to print only the mismatched parts of a data-structure while elliding the matched parts.
• fix more issues when using non-composite matchers (m/regex, m/pred, etc) inside match-with.

3.8.6 / 2023-07-18

• Add all-of matcher, which takes any number of matchers, successfully matching when all match.
• Add 2-arity pred matcher where the second argument is a description text.
  • Useful for mismatch messages when the pred is an anonymous function.

(match-roughly? <delta> <expected> <actual>)

BREAKING CHANGE

We removed matcher-combinators.utils/match-roughly in 3.0.0. If you were using it, you should use matcher-combinators.matchers/within-delta instead. We've documented matcher-combinators.utils as "Internal use only." for clarification.

[2.1.1]

• fix issue matching false in the context of sets #124

[2.1.0]

• extend Matcher protocol to Symbol in cljs #131

[2.0.0]

• add matchers/matcher-for #123
• use set matching logic for java.util.Set #125
• add core/indicates-match? and deprecate core/match?
  • core/match? is mostly for internal use and occasionally used to build match? fns in other libraries

BREAKING CHANGE

matcher-combinators-2.0.0 includes a breaking change for custom implementations of the matcher-combinators.core/Matcher protocol:

• change the implementation of match to -match (required)
• add an implementation of -matcher-for (optional, but recommended)
  • should just return this e.g. `(-matcher-for [this] this)

[1.5.2]

• fix double eval of clojure.test match-equals? arguments

[1.5.1]

• refactor macro to align w/ Clojure docs (no behavioural change)

[1.5.0]

• Implement default equality matching for objects. If classes don't explicity implement the match protocol, they now default to using equality matching.

[1.4.0]

• add matcher-combinators.standalone/match (test-framework independent)

[1.3.1]

• add arglist for cljtest assert expressions

[1.3.0]

Add new matching context for clojure.test:

• match-roughly?: Matches all numerics as long as they are within a given delta of the expected.

[1.2.7]

• Optionally allow omitting the first argument to thrown-match?: (thrown-match? {:foo 1} (bang!)

[1.2.6]

• replace +' with + and -' with - in roughly matching
• Default to equals matcher for array-seq

[1.2.5]

• Default to equals matcher for chunked-sequences

[1.2.4]

• Default to equals matcher for URIs

[1.2.3]

• Fix performance regression with order-agnostic matchers (in-any-order, embeds, set-{embeds|equals})

[1.2.2]

• Fix clojurescript import issue No such namespace: clojure.test

[1.2.1]

• Fix issue where clojure.test mismatches wouldn't report the correct line number or file

[1.2.0]

Add new matching contexts: For Midje:

• match-with: takes a class->matcher map and an expected matcher. The map defines what matcher will be used by default when a particular class instance is found.
• match-equals: Allows for exact matching of datastructures by using the equals matcher instead of embeds for maps.
• match-roughly: Matches all numerics as long as they are within a given delta of the expected.

For clojure.test:

• match-with?: same as the midje version above
• match-equals?: same as the midje version above As well as matcher-combinator.test/build-match-assert to help build new matcher contexts

[1.1.0]

• Improve cider + cursive integration by using :fail, which is the standard in clojure.test for reporting mismatches. Thanks to Arne Brasseur (@plexus) for implementation

[1.0.1]

• Provide clearer message on incorrect arg count to match? and thrown-match?

[1.0.0]

• [BREAKING] When a record is in the expected position of the matcher, the actual value must be a record of the same type.

  Previous behavior would match if the actual was a map with the same keys, or a record of a different type with the same keys

[0.9.0]

• matcher for asserting absence of key

[0.8.4]

• fix cljs related warning in math.combinatorics

[0.8.3]

• fix compatibility issue with shadow-cljs

[0.8.0]

• parser support for java classes

[0.7.0]

• clojurescript support

[0.6.1]

[0.4.2]

• parser support for LocalTime

[0.4.1]

• multiple-arity fix for standalone matching api

[0.4.0]

• api for using matching logic as a yes/no predicate, without access to mismatch info

[0.3.4]

• fix typo in spec that causes errors when spec checking is enabled

[0.3.3]

[0.3.2]

• fix for embeds sequence matching where some matches weren't found

[0.3.1]

• fix issue matching core clojure sequence types like Repeat (#26)

[0.2.7]

• fix issue where a 'missing' was showing as a 'mismatch'

[0.2.6]

• namespace the custom :mismatch directive for clojure.test reporting

[0.2.5]

• add default parser for Integer and Float
• make mismatches for sets and the prefix matcher more informative

[0.2.4]

• fix issue when matching in the presence of midje metaconstants

[0.2.3]

• fix issue matching empty sets

[0.2.2]

• implement default matcher parser for sets

[0.2.1]

• stop using boolean? which is only in clojure 1.9

[0.2.0]

• BREAKING:
  • rename equals-map, equals-seq, and equals-value to all be equals and do dispatch based on type
  • rename sublist to prefix
  • rename subset sequence matcher to be embeds
  • rename contains-map to embeds and make it do dispatch based on type
• implement matchers for sets: equals and embeds as well as set-equals and set-embeds which allow one to use sequences to match sets, skirting the issue that a set matcher of form #{odd? odd?} will reduce to #{odd?}.
