CI: Discover and build with usermod envs - 0.16 - #5835
Conversation
wled#5649) * ci: discover and build custom PlatformIO envs from usermods platformio_override.ini.sample files Adds two new jobs to the Usermod CI workflow to address issue wled#5648: - get_custom_build_envs: scans all usermods/*/platformio_override.ini.sample files and emits a matrix of {usermod, env} pairs by extracting [env:*] section names - build_custom: builds each discovered environment by copying the .ini.sample as platformio_override.ini and running pio run -e <env> This allows PRs introducing usermods with custom build environments (such as pixels_dice_tray) to have those environments validated in CI without committing platformio_override.ini to the repository. * ci: consolidate usermod build envs into per-usermod platformio_override.ini.sample files Move usermod-specific PlatformIO environments out of the root platformio_override.sample.ini and into dedicated files within each usermod's own directory, making them discoverable by CI: * run on push * Fix AHT10_v2 example * no d1_mini env * no d1_mini env * ci: filter usermod matrix to only build changed usermod directories Instead of building every usermod with a library.json on each PR, use git diff to identify which usermods/ subdirectories were actually touched and intersect that with the known-good library.json list. This reduces CI time significantly for PRs that only modify one or two usermods (previously every PR triggered ~40 usermods × 4 chipsets). Also removes the unnecessary PlatformIO install from get_usermod_envs (the step only uses shell/jq, not pio) and adds fetch-depth: 0 to ensure the base branch is available for the diff. * SN_Photoresistor * fix(ci): use PR base SHA for diff and guard jobs against push events github.base_ref is empty on push events, causing 'ambiguous argument origin/...HEAD'. Fix by: - Adding github.event_name == 'pull_request' guard to both jobs so they never run on push events where pull_request context is absent - Replacing origin/${{ github.base_ref }}...HEAD with ${{ github.event.pull_request.base.sha }} HEAD which uses the concrete base commit SHA provided by GitHub directly * ESP32 builds all V4 * fix: rename/fix platformio_override sample files across usermods - Rename *.ini (gitignored) and *.sample.ini (wrong extension order) to the correct platformio_override.ini.sample convention so CI discovers them - Fix AHT10_v2: custom_usermods AHT10 → AHT10_v2 (match library.json name) - Fix INA226_v2: custom_usermods INA226 → INA226_v2 (both envs) - Fix TTGO-T-Display: replace direct [env:esp32dev] override with a named env that extends esp32dev; add note that library.json is absent so custom_usermods is not available for this usermod Affected usermods: AHT10_v2, DHT, INA226_v2, SN_Photoresistor, TTGO-T-Display, Temperature, four_line_display_ALT, rotary_encoder_ui_ALT * perf: filter custom build matrix to changed usermods on PRs On pull_request events, get_custom_build_envs now only scans usermod directories that changed in the PR (matching the behaviour of the get_usermod_envs job). On push events (e.g. merging a PR) it still scans all usermods to validate the full set. * fix release name * fix release name * fix: resolve 8 CI build failures in custom usermod environments - BME280_v2: fix default_envs typo (usermod_bme280_esp8266_2m → usermod_esp8266_2m to match actual [env:] section name) - DHT: replace extends env:custom32_LEDPIN_16 (not in this fork) with env:esp32dev + -D LEDPIN=16; rename env accordingly - SN_Photoresistor: replace ${common.build_flags_esp8266} (key absent in this fork) with ${env:esp8266_2m.build_flags} / lib_deps equivalent - sht: guard ESP.getChipModel() behind #ifdef ARDUINO_ARCH_ESP32 — method does not exist on ESP8266 (fixes custom_esp8266_2m_usermod_sht build) - EleksTube_IPS: delete platformio_override.ini.sample — library.json is disabled so the env cannot build; delete rather than ship a broken sample - pixels_dice_tray: exclude from build_custom matrix (same as standard matrix) — BLE library incompatibility with current IDF causes build failure - workflow: add PWM_fan / BME68X_v2 to exclusion list in get_custom_build_envs for consistency with get_usermod_envs * Do not add platformio_override.ini.sample just because example was in readme --------- Co-authored-by: Frank Möhle <91616163+softhack007@users.noreply.github.com>
Catch any incorrect debug prints for all targets.
The usermod CI previously ran two parallel tracks: a "plain" build (get_usermod_envs + build) and a separate "custom env" build (get_custom_build_envs + build_custom) for usermods needing bespoke PlatformIO settings. This duplicated most of the gather/build logic. Merge them into a single get_usermod_envs + build pipeline. For each changed usermod, if it supplies a sample ini, use it; otherwise build with the reference platformio_override.usermods.ini. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Enable validation for all pull requests and pushes.
The workflow triggers on pull_request and push changes under usermods/**, but get_usermod_envs runs only for fork pull requests. Same-repository pull requests and pushes skip it, and build skips for the same reason. For pushes, use a push-specific matrix discovery path because github.event.pull_request.base.sha is unavailable.

Use milliseconds for the measurement interval.
The sample documents this option as milliseconds and describes 60 seconds as the intended interval. The value 60 therefore configures 60 ms, not 60 seconds. The usermod uses the macro directly as readingInterval and compares it with millis(). Set the value to 60000 if 60 seconds is intended. (github.com)

Restore the SD-card storage-mode define.
custom_usermods = * includes usermods/sd_card, but [env:usermods] supplies neither WLED_USE_SD_SPI nor WLED_USE_SD_MMC. The usermod therefore compiles without SD_ADAPTER and without a storage initialization call. Keep -D WLED_USE_SD_SPI or add the appropriate storage-mode define.

This was a workaround to support the SD card usermod. We plan to adjust #5679 so this is not needed any more.

@softhack007, thanks for the clarification.
#5679 is still open and is not part of this PR. Its new SD-card sample environments still set either WLED_USE_SD_SPI or WLED_USE_SD_MMC explicitly. Until the usermod build workflow selects one of those environments instead of [env:usermods], this change leaves the default usermods build without a storage mode.
Please include the dependent workflow change here, or merge/rebase the completed #5679 change before removing the define.

Learning: In WLED, `platformio.ini` `[env:usermods]` previously defined `WLED_USE_SD_SPI` as a workaround to compile the `usermods/sd_card` usermod in the aggregate usermods environment. The planned replacement is usermod-specific SD-card environments in pull request `#5679` that explicitly select either `WLED_USE_SD_SPI` or `WLED_USE_SD_MMC`.

Learning: In platformio.ini for WLED, understand that usermods can be pulled as out-of-tree dependencies via lib_deps (external repositories). The custom_usermods setting controls only in-tree usermods; setting custom_usermods = (empty) disables in-tree usermods but does not disable out-of-tree usermods included through library dependencies.
