singlejson 0.3.0

Load and save json files as a global object

singlejson

A very simple set of utilities for working with JSON in Python.

View the documentation here.

Features:

• Easy loading of JSON files
• Only one instance for each opened file
• This library doesn't feature much more, just the basics

Installation:

Install singlejson using pip

pip install singlejson

Usage:

Loading JSON from file:

import singlejson

file = singlejson.load('file.json')  # Load file.json
# Returns a JSONfile object which has the json property
file.json["fun"] = True  # Edit some values in the JSONfile

But if we try to load the same file from the filesystem again, we get the same object:

file2 = singlejson.load('file.json')
print(file2.json["fun"])  # will output True

To save the file back to the disk we call file.save()
Maybe you don't want your program to save file contents only upon successful execution, then you just have to call singlejson.sync() at the end of your program to save all changes to the filesystem.

If the requested file doesn't exist, the file and its parent directories will be created and the "default" values will be written to the file. Should the root "node" of your JSON be a List, you may specify that the default to save is an empty list using singlejson.load(file, default="[]")

Building the documentation locally

The docs are configured to install via an optional dependency group in pyproject.toml (PEP 621). You don’t need a separate requirements.txt.

Quick steps:

# From the project root
python -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
pip install -e .[docs]

# Build HTML docs into docs/_build/html
python -m sphinx -b html docs/source docs/_build/html

Notes:

• The Sphinx theme is furo. Versions are declared under [project.optional-dependencies].docs in pyproject.toml.
• For a clean test, use a fresh virtual environment as shown above (preferred over uninstalling global packages).

Contributing:

This is just a fun project of mine mainly to try out python packaging. If you would like to contribute or have a feature-request, please open an issue or pull request.
