Command-line interface for DICE

DICE Command Line Interface (CLI)

Installation

The best way to install dice-cli is via pipx. This will setup a separate virtualenv for dice-cli preventing interference with your normal Python setup.

pipx install dice-cli

For tab-completion of the DICE CLI, you can run

dice --install-completion

which will install the completion for your shell.

Should you be using a "non-standard" shell, you can check what will be installed through

dice --show-completion

Development

Development cycle

dice-cli has a direct, tight dependency on dice-lib. New features are usually developed within dice-cli first, and then common functionality is moved to dice-lib.

Code layout

CLI commands are currently grouped into two categories: admin and user. All categories, except for user need to be placed in their respective folders. Each category should use its own logging and error handling to allow for individual tuning.

Main commands are implemented directly into <category>/__init__.py, e.g. dice admin scan_groups_and_users, while subcommands should be placed in <category>/<command>/__init__.py, e.g. dice job why_is_my_job_not_running.

Should a command require extensive logic, it should be placed in its own file , e.g. admin/_print_used_id_ranges.py. This will be the main point of change when things move to dice-lib.
