compress-json 1.0.2

Python package that handles loading and dumping json files in a compressed fashion.

Python package that handles loading and dumping json files in a compressed fashion. The library is loosely based on the compress_pickle library.

How do I install this package?

As usual, just download it using pip:

pip install compress_json

Tests Coverage

Since some software handling coverages sometime get slightly different results, here’s three of them:

Available compression modes

The compression modes, detected automatically by the file name, are gzip, bz2 and lzma, with the notable exception of zip which seems difficult to integrate in the json pipeline.

Usage example

The library is extremely easy to use:

import compress_json

D = {
    "A":{
        "B":"C"
    }
}
compress_json.dump(D, "filepath.json.gz") # for a gzip file
compress_json.dump(D, "filepath.json.bz") # for a bz2 file
compress_json.dump(D, "filepath.json.lzma") # for a lzma file

D1 = compress_json.load("filepath.json.gz") # for loading a gzip file
D2 = compress_json.load("filepath.json.bz") # for loading a bz2 file
D3 = compress_json.load("filepath.json.lzma") # for loading a lzma file

Advanced usage

Clearly you can pass parameters to either the chosen compression mode or the json library as follows:

import compress_json

D = {
    "A":{
        "B":"C"
    }
}
compress_json.dump(
    D, "filepath.json.gz",
    compression_kwargs = {kwargs go here},
    json_kwargs = {kwargs go here}
)

D4 = compress_json.load(
    "filepath.json.gz",
    compression_kwargs = {kwargs go here},
    json_kwargs = {kwargs go here}
)
