name: Cache ESP-IDF
description: >
Resolve the pinned ESP-IDF version and cache the native ESP-IDF install
(toolchains + source) at ~/.esphome-idf. Every job that installs ESP-IDF
natively (clang-tidy for IDF/Arduino and the component test batches) shares
one cache, since the install is identical (ESPHOME_IDF_DEFAULT_TARGETS
defaults to "all", so all toolchains are present regardless of the chip).
Callers must set env ESPHOME_ESP_IDF_PREFIX: ~/.esphome-idf and have the
Python venv already restored.
inputs:
framework:
description: 'Which pinned IDF version to key on: "espidf" (recommended) or "arduino".'
default: espidf
restore-only:
description: >
When "true", only restore -- never save the cache, even on dev. Use from
jobs that may not produce an ESP-IDF install (e.g. a component batch with
no esp32 target), so a partial/empty install is never written to the key.

# Mirror the adjacent PlatformIO cache: only dev-branch runs write the

# their own scope / the repo quota (e.g. on a version-bump PR).
