• Extending Functionality
  • Adding a new input source
  • Adding a new output format

The CLI accepts optional input and output arguments:

• input: the path to the input file (can be a URL or a path to a local file). default: orders.jsonl
• output: the path to the output file - the program will also determine the desired output format based on the file extension (*.csv and *.jsonl are supported). default: out.csv

For convenience, a Makefile is provided which allows for use within a containerized environment.

• Docker
• GNU make

For standard usage:

• make run: runs the CLI, installing dependencies if they haven't been already. You can optionally provide input/output arguments by setting the INPUT and OUTPUT environment variables. When used with local files, paths must be relative to the project root in order to ensure they are accessible from within the container - this applies to both input and output paths.
  • Examples:
    • INPUT="my-orders.jsonl" OUTPUT="processed-orders.jsonl" make run
    • INPUT="https://example.com/orders.jsonl" OUTPUT="processed-orders.csv" make run

Running tests:

• make test: runs all tests using PHPUnit.

Formatting code:

• make fix: uses php-cs-fixer to format the src directory.

If you'd prefer to set up/run the CLI yourself you may do so.

• PHP 8.1 or later
• Composer 2

For standard usage:

• composer install in the project root to install required dependencies.
• php src/app.php to run the CLI, optionally providing the input/output arguments described previously.
  • Examples:
    • php src/app.php my-orders.jsonl processed-orders.jsonl
    • php src/app.php https://example.com/orders.jsonl processed-orders.csv

Running tests:

• bin/phpunit tests: runs all tests using PHPUnit

Formatting code:

• composer install --working-dir=tools/php-cs-fixer: installs the required dependencies for php-cs-fixer.
• tools/php-cs-fixer/vendor/bin/php-cs-fixer fix src: uses php-cs-fixer to format the src directory.

Create a new service in src/Services which extends the App\Services\AbstractStreamReader class and implement the abstract methods defined within (supports, readBytes and close) - the docblocks in AbstractStreamReader describe the expected inputs/outputs for these methods. Once your new service is built you can add it to the $inputStream match block in src/app.php so that it can automatically be resolved based on the input provided to the CLI. You can look at the existing *StreamReader services for inspiration.

Create a new service in src/Services which extends the App\Services\AbstractStreamWriter class and implement the abstract methods defined within (supports and writeLine) - the docblocks in AbstractStreamWriter describe the expected inputs/outputs for these methods. Once your new service is built you can add it to the $outputStream match block in src/app.php so that it can automatically be resolved based on the output provided to the CLI. You can look at the existing *StreamWriter services for inspiration.
