ir-canonical

A canonical media-control vocabulary and a Flipper-IRDB name → canonical mapping, published as a small Python library so both the ESPHome codegen (esphome-ir-codegen) and Concerto can resolve remote buttons semantically instead of matching raw strings.

Why

Flipper-IRDB has no enforced button naming — 54,415 distinct names over 301,921 occurrences. "Volume up" alone appears as VOL+, Vol_up, VOLUME_UP, VOL_^, TV_Vol+, AMP_VOL+, … So you cannot match a control by raw name.

Use it

pip install homeops-ir-canonical

from ir_canonical import resolve, canonical, MAP

resolve("VOL+")        # -> "volume_up"  (curated lookup, baked at build time)
resolve("TV_Power")    # -> "power_toggle"
canonical("Ch_prev")   # -> "channel_down"  (rule engine; maps unseen spellings)
canonical("HDMI_1")    # -> "input_hdmi_1"
MAP["vol+"]            # the flat {alias: canonical} dict, lower-cased keys

• resolve(name) — fast curated lookup via the bundled, human-maintained controls/ tree (compiled to control_map.json at build time).
• canonical(name) — the broad rule-based engine; resolves spellings the curated tree hasn't enumerated yet, and the full vocabulary (not just the core).

Both are case-insensitive.

The curated controls tree (edit this by hand)

src/ir_canonical/controls/ is the human-owned source of truth for the core controls that matter for driving activities (power / volume / channel / transport / navigation / digits / source — a curated subset):

src/ir_canonical/controls/
  Volume_Up/aliases.json     ["VOL+", "Vol_up", "VOLUME_UP", "AMP_VOL+", ...]
  Power_Toggle/aliases.json  ["POWER", "STANDBY", "TV_POWER", "PWR", ...]
  ...

Edit any aliases.json to prune or extend a control. The build bakes the tree into control_map.json (so installs get an instant lookup); CI fails the build if two controls claim the same alias.

Beyond IR: app and gamepad families

Two families extend the vocabulary past classic IR remotes so one control language spans IR, BLE, and native transports:

• app_* — video-app launch hotkeys (app_netflix, app_youtube, app_prime_video, app_disney_plus, …). These appear on real IR remotes, so both resolve() and canonical() map their Flipper spellings.
• pad_* — gamepad controller inputs (pad_a, pad_up, pad_l1, pad_start, …). These have no IR source — they exist purely as cross-transport canonical vocabulary, so resolve()/canonical() only match the namespaced pad_* spellings, not arbitrary remote names.

Layout

Develop

python -m build --wheel --no-isolation     # build (bakes the map)
pip install dist/*.whl && pytest -q         # test as a consumer
python seed.py /path/to/Flipper-IRDB-clone  # re-seed the tree (won't clobber edits)

Release & publish

Versioning is managed by release-please (Conventional Commits). Merging the release PR tags a GitHub Release, which triggers publish.yaml to upload the wheel to PyPI via trusted publishing.

One-time PyPI setup: create the homeops-ir-canonical project and add a trusted publisher → owner HomeOps, repo ir-canonical, workflow publish.yaml, environment pypi.
