dictsdiff 0.1.0

Examples

$ echo '{"a": 1, "b": {"c": 0, "d": 0, "e": 0}}' > 0.json
$ echo '{"a": 2, "b": {"c": 0, "d": 1, "e": 0}}' > 1.json
$ echo '{"a": 2, "b": {"c": 0, "d": 1}}' > 2.json
$ dictsdiff *.json
        a  b.d  b.e
path
0.json  1    0  0.0
1.json  2    1  0.0
2.json  2    1  NaN
$ cat *.json | dictsdiff
   a  b.d  b.e
0  1    0  0.0
1  2    1  0.0
2  2    1  NaN

If JSON files are pre-processed by jq, dictsdiff can handle its output when --compact-output/-c is passed:

jq --compact-output '' **/*.json | dictsdiff

To pass the original file path of JSON files to dictsdiff, use --info-key option combined with jq’s input_filename, e.g.,:

jq --compact-output '.path = input_filename' **/*.json \
  | dictsdiff --info-key=path
