JSON Configuration Validator

A modular Bash-based utility designed to automate the validation of JSON schema requirements across a project directory. This tool demonstrates the use of functional libraries, shell scripting, and automated file discovery.

Getting Started

1. Installation & Setup

Clone the repository and ensure the scripts have the correct execution permissions:

chmod +x bin/validate_json.sh
chmod +x lib/tools.sh

2. Project Structure

The application uses a modular architecture to separate logic from utility functions:

bin/validate_json.sh: The main execution script containing the validation loops.

lib/tools.sh: A shared library providing standardized error handling (error_msg).

3. Create Your Test Data

Run these commands in the terminal to create a "Good" and "Bad" file:

echo '{"version": "1.0", "author": "Student"}' > config_good.json
echo '{"name": "test_app"}' > config_bad.json

4. Execution

Run the validator from the project root:

./bin/validate_json.sh

5. Output

Determine if the output for the json files test are perfect:

Starting JSON Schema Validation...
PASS: ./data/config_v1.json
PASS: ./settings/user_profile.json
ERROR [2026-03-24 20:20:45]: Mandatory 'version' key missing in ./temp/old_config.json
Validation Complete.
