# JSON Expand-O-Matic
Expand a dict into a collection of subdirectories and json files or contract (un-expand) the output of expand() into a dict.
## Overview
Construct
expandomatic = JsonExpandOMatic(path=data_path, logger=logger)
Expand -- become or make larger or more extensive.
data = { ... }
data_path = sys.argv[1] if len(sys.argv) > 1 else '.'
Create {data_path}/root.json and {data_path}/root/...
expandomatic.expand(data)
Create {data_path}/foo.json and {data_path}/foo/...
expandomatic.expand(foo, root_element='foo')
Warning: expand() is destructive unless `preserve=True`
Contract -- decrease in size, number, or range.
data = expandomatic.contract()
Or use jsonref
import jsonref
with open(f'{data_path}/root.json') as f:
data = jsonref.load(f, base_uri=f'file://{os.path.abspath(data_path)}/')
## Quick Start
Setup wrapper scripts:
./wrapper.sh
Install for development:
./tox.sh
Do a thing:
rm -rf output
./expand.sh output tests/testresources/actor-data.json 2>&1 | tee log.txt
find output -type f | sort
Do another thing:
rm -rf output
./expand.sh output tests/testresources/actor-data.json '[{"/root/actors/.*": ["/[^/]+/movies/.*"]}]' 2>&1 | tee log.txt
find output -type f | sort
## Testing
Install & use tox:
./tox.sh
Update requirements.txt and dev-requirements.txt:
./tox.sh -e deps
Reformat the code to make it pretty:
./tox.sh -e fmt
Manually run the commands:
./wrapper.sh
./expand.sh output tests/testresources/actor-data.json
./contract.sh output | jq -S . > output.json
ls -l output.json tests/testresources/actor-data.json
cmp output.json <(jq -S . tests/testresources/actor-data.json)
