jsonselect.py is a python implementation of https://github.com/fd/json_select
You can find more information here http://jsonselect.org/
There are plenty of other currently maintained libraries that accomplish the same thing
However, if you submit a concise and tested patch, I will probably merge it in.
jsonselect.py currently implements levels 1 & 2 of these conformance tests https://github.com/lloyd/JSONSelectTests
level 3 is unimplemented because I was having trouble understanding what the correct behavior should be
jsonselect can be called directly from the command line.
python -m jsonselect <selector> < jsonfile
This is usefull, for example, for parsing out values from JSON APIs.
$aws ec2 describe-instances --filters "Name=tag:Name,Values=kafka" | python -m jsonselect .InstanceId
["i-12345678", "i-23456789", "i-3456789A"]usage: __main__.py [-h] [--list | --machine-readable] selector [infile]
parse json with jsonselect.
positional arguments:
selector
infile
optional arguments:
-h, --help show this help message and exit
--list, -l new-line separated list of values. works best on lists.
--machine-readable Print json with no formatting
##Tests
get the upstream conformance tests: git submodule update --init
Run specific level conformance tests with nosetests -m '.*_level_1' ./tests/test_conformance.py
