Please add at least one test.

Hi! @vstinner I’ve pushed the updated changes to the add-extra-metadata branch. Integrated the --extra-metadata feature cleanly into the existing compare_to flow. Fixed implementation issues that caused errors when formatting metadata output. Resolved merge conflicts during branch sync and ensured the final code reflects only the correct logic. Added a dedicated test file: Verified full test suite — all tests pass successfully (174 passed). Ensured that: Baseline behavior of compare_to is unchanged Metadata output only appears when explicitly requested No regressions in table, CLI, verbose, or non-significant cases. Updated the PR branch cleanly using cherry-pick without opening a new PR. Happy to make any additional adjustments if required! |

Please leave this code unchanged, I prefer to fit into 80 columns.

I would prefer to reuse one of the existing benchmark file in pyperf/tests:
mult_list_py36.json
mult_list_py36_tags.json
mult_list_py37.json
mult_list_py37_tags.json
mult_list_py38.json
telco.json

Can you add a test to pyperf/tests/test_perf_cli.py instead?

pyperf/tests/test_perf_cli.py already has a run_command() method.

Hi @vstinner , thanks for the review! I have addressed all your comments: Moved the test to pyperf/tests/test_perf_cli.py and used the existing create_bench helper. Fixed the merge conflict in main.py and cleaned up the argument definition. Fixed the code style in _compare.py (indentation, comments, and line wrapping) as requested. Tests are passing locally. Please let me know if there is anything else! |

Summary
This pull request adds support for a new --extra-metadata argument to the compare_to command.
It allows users to include selected metadata keys as additional columns in the comparison table output.
Motivation
The current compare_to output does not show metadata values such as CPU model, OS version, Python build info, etc.
This feature was requested in Issue #162 (“Display additional information through table”) to make analysis more informative.
What This PR Does
Adds a new CLI flag:
--extra-metadata "key1,key2,..."
Passes metadata keys into _compare.py
Updates table generation to show metadata for both reference and changed benchmarks
Ensures geometric mean rows remain aligned
Testing
Manually tested using sample benchmark files
Verified table output for:
No metadata requested
Single metadata key
Multiple metadata keys
Mixed significant / non-significant benchmarks
Notes
Feedback is welcome! I’m happy to update the PR if changes are needed.
