JsonDiffEx
Diff and patch for JSON in Elixir, works really well and is really fast
Installation
First, add JsonDiffEx to your mix.exs dependencies:
def deps do
[{:json_diff_ex, "~> 0.5.0"}]
end
Then, update your dependencies:
$ mix deps.get
Using
Diff
Simple example:
JsonDiffEx.diff %{"test" => 1}, %{"test" => 2}
#=> %{"test" => [1, 2]}
Now with list:
JsonDiffEx.diff %{"test" => [1,2,3]}, %{"test" => [2,3]}
#=> %{"test" => %{"_0" => [1, 0, 0], "_t" => "a"}}
Now with a map in the map:
JsonDiffEx.diff %{"test" => %{"1": 1}}, %{"test" => %{"1": 2}}
#=> %{"test" => %{"1": [1, 2]}}
Now with a map in an list in the map:
JsonDiffEx.diff %{"test" => [%{"1": 1}]}, %{"test" => [%{"1": 2}]}
#=> %{"test" => %{"0" => %{"1": [1, 2]}, "_t" => "a"}}
Patch
Simple example of a patch:
JsonDiffEx.patch %{"test" => 1}, %{"test" => [1, 2]}
#=> %{"test" => 2}
Now a patch with list:
JsonDiffEx.patch %{"test" => [1,2,3]}, %{"test" => %{"_0" => [1, 0, 0], "_t" => "a"}}
#=> %{"test" => [2,3]}
Now a patch with a map in the map:
JsonDiffEx.patch %{"test" => %{"1": 1}}, %{"test" => %{"1": [1, 2]}}
#=> %{"test" => %{"1": 2}}
Now with a map in an list in the map:
JsonDiffEx.patch %{"test" => [%{"1": 1}]}, %{"test" => %{"0" => %{"1": [1, 2]}, "_t" => "a"}}
#=> %{"test" => [%{"1": 2}]}
Compatibility
Should work with jsondiffpatch and the test cases currently test make sure we keep that compatibility.
Profiling
Get medium profiling tests
$ MIX_ENV=test mix run profile/get_usda_json.exs
Run medium profiling tests
$ MIX_ENV=test mix run profile/medium.exs
Run medium profiling tools
$ MIX_ENV=test mix profile.fprof profile/medium.exs
Get big profiling tests
$ MIX_ENV=test mix run profile/get_mtg_json.exs
Run big profiling tests
$ MIX_ENV=test mix run profile/big.exs
Do not run the big profile with mix profile.fprof unless you
have a really good computer and don't mind crashing your computer,
haven't been able to finish it my self.
