62+## Development Workflow (If you plan on using Stack)

63+

64+Here we outline a general workflow new contributors could adopt for a nice incremental development experience.

65+

66+The root folder consists of two stack-*.yaml config files.

67+

68+1. stack-nightly.yaml - Config file defines all the settings to build and test any changes.

69+2. stack-bench.yaml - Used to run benchmark tests.

70+3. stack-ffi-unescape.yaml - This is for replacing certain parts with a C-implementation.

71+

72+Therefore, a ghci development experience would be:

73+

74+1. `stack ghci --stack-yaml stack-nightly.yaml --test`

75+2. :r to recompile

76+3. `main` to run all tests, or `:main --pattern Foo` to run specific tests matched by pattern.

77+

78+Some discussion on this topic can also be found here [here](https://github.com/bos/aeson/issues/733)

79+

80+Of course before submitting a PR, the following steps are recommended:

81+

82+1. 'stack test --stack-yaml stack-nightly.yaml` - Run the entire suite of tests

83+2. `make hlint` - Run hlint on the source folders.

84+3. 'stack test --stack-yaml stack-bench.yaml` - Run the benchmark tests if you believe your changes could affect the benchmarks.

85+

86+## Development Workflow (If you plan on using Cabal)

87+

88+A ghci development experience would be:

89+

90+1. `cabal new-repl test:tests`

91+2. `:r` to recompile

92+3. `Main.main` to run all tests, or `:m Main; :main --pattern Foo` to run specific tests matched by pattern.

93+

94+Of course before submitting a PR, the following steps are recommended:

95+

96+1. `cabal new-test` - Run the entire suite of tests

97+2. `make hlint` - Run hlint on the source folders.

98+3. Uncomment the `benchmarks` line in `cabal.project` - Run the benchmark tests if you believe your changes could affect the benchmarks.

3+### upcoming

5+* `FromJSON` instance of `Ratio a` now parses numbers in addtion to

6+ standard `{numerator=..., denumerator=...}` encoding.

8+### 1.4.6.0

10+* Provide a clearer error message when a required tagKey for a constructor is missing, thanks to Guru Devanla.

11+ The error message now looks like this: `Error in $: parsing Types.SomeType failed, expected Object with key "tag" containing one of ["nullary","unary","product","record","list"], key "tag" not found`

12+

13+* Add `formatPath` and `formatRelativePath` functions to turn a `JSONPath` into a `String`, thanks to Robbie McMichael

14+

15+

3### 1.4.5.0

16### 1.4.5.0

5* Expose `(<?>)`, `JSONPath` and `JSONPathElement(..)` from `Data.Aeson.Types`. Previously only available through internal modules. Thanks to Luke Clifton.
