Feature: CLI docstring example validation As a documentation maintainer I want to ensure CLI docstring examples respect positional argument order So that published documentation accurately reflects the command signature Scenario: Validator detects positional arguments before options Given I have a CLI command with positional arguments and options When I validate the command's docstring examples Then the validation should pass for examples with positional args before options Scenario: Validator rejects options before positional arguments Given I have a CLI command with positional arguments and options When I validate the command's docstring examples Then the validation should fail for examples with options before positional args Scenario: Validator handles commands without examples Given I have a CLI command without docstring examples When I validate the command's docstring examples Then the validation should pass for commands without examples Scenario: Validator parses example lines with shlex Given I have a CLI command with quoted arguments in examples When I validate the command's docstring examples Then the validation should correctly parse quoted arguments Scenario: Validator reports clear error messages Given I have a CLI command with invalid docstring examples When I validate the command's docstring examples Then the error message should identify the command and example line And the error message should explain the positional argument order requirement
