fix: References to upstream click causing further side effects (#1754)

[Meizzajanor]

This pull request removes the dependency on click and fully migrates the CLI and related error handling to use typer and its APIs. It updates imports, exception handling, and test code accordingly. Additionally, it refactors the version display logic to use importlib.metadata for version retrieval.

Key changes include:

Dependency and Import Cleanup:

• Removed click from the dependencies in pyproject.toml and all code imports, replacing them with typer or typer._click.exceptions where necessary. [1] [2] [3] [4] [5] [6] [7]

Error and Exception Handling:

• Replaced all uses of click.FileError and click.BadParameter with typer equivalents throughout the codebase and tests, ensuring consistent error handling. [1] [2] [3] [4]

CLI Output and Echo:

• Updated all click.echo calls to typer.echo for output and error messages. [1] [2] [3]

CLI Version Handling:

• Refactored version reporting to use a --version option handled via a typer callback, retrieving the version with importlib.metadata instead of importing from the package. [1] [2] [3] [4] [5]

Test Suite Updates:

• Updated all test cases to use typer.Exit and related exceptions instead of click exceptions, ensuring tests remain valid after the migration. [1] [2] [3]

These changes collectively modernize the CLI implementation, streamline dependencies, and improve maintainability by unifying on the typer library.

Issues:
Closes #1754 .

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Replaces direct click dependency usage with typer equivalents throughout the codebase, and switches __version__ import to importlib.metadata.

Changes:

• Remove click from dependencies and replace click.echo, click.BadParameter, click.exceptions.Exit, click.FileError with typer equivalents.
• Replace click.version_option with an explicit Typer --version callback.
• Use importlib.metadata.version("robotframework-robocop") instead of robocop.__version__.

Since we already store the version under from robocop import version, why not use it? Is there any reason for chosing metadata.version over the version from the package directly?
