elbow_helper.cli_click module
click command-line interface — the optional, ergonomic CLI twin.
Identical behaviour to elbow_helper.cli_argparse, but built on click
for a nicer help/UX. click is an optional dependency (pip install
'elbow-helper[cli]'): the argparse CLI is the always-available one, so
importing this module lazily requires click and fails with an actionable
message if it is missing. Every command delegates to the shared
elbow_helper._core_cli, so the two CLIs can never drift apart.
Consumes: click (optional), elbow_helper._core_cli, os_helper.
Produces: cli() (the elbow-helper-click console-script entry point).
- elbow_helper.cli_click.main()[source]
Console entry point (
elbow-helper-click).click’s own
main()only special-casesClickException/Abort(and a broken pipe); a plain library exception (e.g.ValueErrorfromlocatoron a malformed curve) would otherwise propagate as a raw Python traceback instead of a clean CLI error. This wraps the whole invocation and translates that last case into a one-line stderr message + exit 1 — click’s own control flow (usage errors,--help, an explicitsys.exit(1)in a subcommand) already raisesSystemExit, aBaseExceptionthis does not catch, so it passes through untouched.- Return type:
None
