Summary

  • add_gear_to_activity()/remove_gear_from_activity() only link/unlink existing gear; there was no way to register a new piece of gear via the API without a manual detour through the Garmin Connect app (Feature request: create new gear (equipment) via API #418).
  • New Garmin.create_gear() mirrors the payload Garmin Connect's web "Add Gear" form sends to gear-service/gear/v2, captured from a real account. Only gear_type="SHOES" and usage_type="DISTANCE" are confirmed; other values are accepted as plain strings (normalized to the confirmed SCREAMING_SNAKE_CASE convention) rather than a guessed enum, since the full set isn't publicly documented.
  • activity_type_keys (e.g. ["running"]) stays lowercase, matching the confirmed payload — a different casing convention than set_gear_default()'s uppercase activityType.
  • demo.py: added an interactive "Create new gear" menu entry, and wired up the activitysubtype filter added to get_activities() in feat: add activitysubtype filter #419 (it never had a demo entry). The type/subtype picker pulls the live type list from api.get_activity_types() rather than needing a config edit.
  • README's API coverage stats were stale well before this PR (missing an entire "Activity Editing" category, wrong Training Plans count) — recomputed from demo.py's menu_categories and corrected throughout.

Test plan

  • python -m pytest tests/test_garmin_unit.py -q (230 passed)
  • ruff check / ruff format --check / mypy all clean
  • Exercised create_gear_data() and get_activities_filtered_data() end-to-end against a fake API

Summary by CodeRabbit

  • New Features

    • Added the ability to create and configure new gear, including usage limits and associated activity types.
    • Added activity filtering by type and subtype in the demo.
    • Expanded the demo to showcase additional API capabilities, including gear creation and activity editing.
  • Documentation

    • Updated the README with revised API coverage statistics, category descriptions, and demo references.
  • Bug Fixes

    • Improved validation for numeric gear usage limits.
  • Tests

    • Added coverage for gear creation, validation, defaults, and request data.

add_gear_to_activity()/remove_gear_from_activity() only link/unlink
existing gear; there was no way to register a new piece of gear itself
without a manual detour through the Garmin Connect app (issue 418).

Mirrors the payload Garmin Connect's web "Add Gear" form sends to
gear-service/gear/v2, captured from a real account. Only
gear_type="SHOES" and usage_type="DISTANCE" have been confirmed; other
values are accepted as plain strings (normalized to the confirmed
SCREAMING_SNAKE_CASE convention) since the full enum isn't publicly
documented and guessing at it risks silently wrong behavior.

Closes #418
… stats

Adds interactive demo.py menu entries for get_activities()'s
activitysubtype filter (already in the library, never had a demo entry)
and for create_gear(). The activity type/subtype picker pulls the live
type list from api.get_activity_types() rather than requiring a config
edit, so it always reflects the account's real taxonomy instead of a
guessed one. Updates the API coverage numbers in README, which had
drifted well before these two additions (missing an entire "Activity
Editing" category, wrong Training Plans count) — recomputed directly
from demo.py's menu_categories rather than hand-counted.

Walkthrough

The PR adds Garmin.create_gear, interactive gear creation, and activity filtering to demo.py. It adds validation tests for gear payloads and updates README API coverage statistics to 145+ methods across 14 categories.

Changes

Gear and activity features

Layer / File(s) Summary
Gear creation API contract
garminconnect/__init__.py, tests/test_garmin_unit.py
Garmin.create_gear validates inputs, converts usage limits, builds the gear payload, and posts it to the gear service. Tests cover payload fields, normalization, validation, finite numbers, and defaults.
Interactive demo workflows
demo.py, tests/test_demo_gear_and_filters.py
The demo adds activity filtering and gear creation prompts, menu entries, dispatch mappings, uppercase A option validation, and regression tests.
API coverage documentation
README.md
README method counts, category counts, descriptions, and demo references now state 145+ methods across 14 categories.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to f5a52

The interactive activity filter may fail before retrieving activities because it assumes a different activity-type response shape than the client contract. Align the client response handling and demo test fixture before merge.

In `@demo.py`:
- Line 3598: Update the caller around call_and_display() to capture its success
flag and print “Gear created!” only when the flag is True; preserve the existing
behavior for rejected payloads or failed requests.
- Line 3518: Validate selected_index is within the range 0 through
len(activity_types) - 1 before the activity_types lookup that assigns
activitytype. Reject negative and out-of-range indexes so invalid input cannot
select an unintended activity type.

In `@garminconnect/__init__.py`:
- Around line 2830-2835: Update the usage-limit conversion logic around
_validate_positive_number for both distance and time limits to reject non-finite
values before conversion and require the converted integer value to be at least
1. Preserve the existing validation flow, but ensure infinite values do not
reach round() and positive sub-unit values cannot become zero in the payload.
- Line 2847: Update the logic surrounding the activity_type_keys iteration to
require activity_type_keys to be a list whenever it is not None, rejecting other
container types such as strings before iteration; then retain or add validation
for each list entry before creating activity associations.

- _validate_positive_number() now rejects non-finite values (inf/nan),
  which previously passed through and then raised an uncaught
  OverflowError from round() in create_gear().
- create_gear() rejects a max_usage_distance_km/max_usage_duration_min
  small enough to round to 0 after unit conversion, since 0 collides
  with the payload's "no threshold" sentinel.
- create_gear() rejects a non-list activity_type_keys (e.g. a bare
  string), which iterated character-by-character and silently created
  one bogus activity association per character.
- demo.py's activity-type picker rejects negative indexes, which are
  valid Python list indexing (selects from the end) but not a valid
  menu selection.
- demo.py's create_gear_data() only prints success after checking the
  success flag call_and_display() returns, instead of unconditionally.

Added regression tests for all five in tests/test_garmin_unit.py and a
new tests/test_demo_gear_and_filters.py.

3506-3508: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Align get_activity_types() with the activity-filter workflow.

Garmin.get_activity_types() declares dict[str, Any], but get_activities_filtered_data() treats the result as a list of activity mappings. Under the declared contract, the loop iterates string keys, so Line 3508 can call .get() on a string and stop before querying activities. connectapi() returns untyped JSON, so the declaration must match the endpoint response.

If the endpoint returns a list, change get_activity_types() to return and declare list[dict[str, Any]]. If it returns a wrapper object, unwrap the activity-list field before iteration. Update tests/test_demo_gear_and_filters.py to use the same contract.
