# sp-variant - detect the Linux distribution for the StorPool build system The `sp-variant` library is mainly useful within the StorPool internal build and QA environment, as well as the first step of installations on end-user systems. It examines several files and tries to determine what distribution and what version it is running on. ## Basic command-line usage - `sp_variant detect` - identify the current Linux distribution - `sp_variant show current` - show JSON data about the current distribution - `sp_variant show all` - show JSON data about all supported distributions - `sp_variant show NAME` - show JSON data about a specific distribution - `sp_variant command list` - show a list of distribution-specific commands - `sp_variant command run category.item [arg...]` - run a distribution-specific command - `sp_variant repo add` - add the Apt or Yum repository definitions for the StorPool package repository ## Basic Python API The `sp_variant.variant` module exports several constants and functions, among them: - `detect_variant()` - return an object describing the detected distribution - `get_variant()` - get an object describing the specified distribution - `get_by_alias()` - same, but specify the StorPool builder alias for the distribution - `get_all_variants()` - get objects describing all supported distributions - `command_run()` - run a distribution-specific command ## Basic Rust API The `sp-variant` crate exports several constants and functions, among them: - `build_variants()` - return information about all supported variants - `detect()` - get an object describing the detected distribution - `get_from()` - get an object describing the specified distribution - `get_by_alias_from()` - same, but specify the StorPool builder alias for the distribution For more information, as well as for suggestions and problem reports, please contact [the StorPool support team](mailto:support@storpool.com).
