"""Generate the Mesh America configurator provider catalog for ZephCore.
The Mesh America Device Configurator (apps.meshamerica.com) merges third-party
"provider catalogs" with the official MeshCore catalog. This script emits our
catalog.json from a release's firmware assets, following the provider API spec
(the `version -> {notes, files:[{type,name,url}]}` shape with absolute HTTPS
URLs -- NOT MeshCore's internal `github`+regex+staticPath mechanism).
Hosting note: GitHub *Release assets* do NOT return Access-Control-Allow-Origin
(they redirect to release-assets.githubusercontent.com, which omits the header),
so the browser-based configurator cannot fetch them. Firmware + this catalog are
instead published to a force-pushed `firmware-dist` orphan branch and served from
CORS-clean hosts: firmware via jsDelivr (`--url-base`), the catalog itself via
raw.githubusercontent.com. `--url-base` is prepended to each firmware filename.
Usage (CI, scanning the built firmware/ dir):
python gen_provider_catalog.py --firmware-dir firmware \
--url-base "https://cdn.jsdelivr.net/gh/liquidraver/ZephCore@firmware-dist" \
--version v20260704.220543 --out catalog.json
Usage (local test, from a GitHub release API json):
python gen_provider_catalog.py --assets-json rel.json \
--url-base "https://cdn.jsdelivr.net/gh/liquidraver/ZephCore@firmware-dist" \
--version v20260704.220543 --out catalog.json

DESCRIPTION = (
"ZephCore is an independent, ground-up implementation of the MeshCore "
"protocol on the Zephyr RTOS. It is wire-compatible with stock MeshCore "
"and adds features such as an adaptive contention window, LoRa RX "
"duty-cycling, and support for additional boards. Companion (BLE + USB), "
"Repeater, and native-Linux builds are provided."
)
# Device thumbnails for our NEW tiles only (folded devices inherit MeshCore's on
# merge). Reused from the configurator's own image set via jsDelivr -- a stable,
# CORS-clean absolute URL. `![]()
` display isn't CORS-restricted, but the spec
# asks for absolute URLs. Boards without dedicated art use the neutral lora icon.
# An `img` starting with http is taken as a full URL and used as-is (vendor
# product shots), instead of being resolved against IMG_BASE.
IMG_BASE = "https://cdn.jsdelivr.net/gh/meshcore-dev/flasher.meshcore.io@main/img"
# Art we ship ourselves, for devices the configurator has no picture of. Source
# of truth is this repo's img/ dir; build.sh copies it into firmware/ so it is
# published alongside the firmware, and the URL is resolved against --url-base
# like every other asset -- so nothing here hardcodes a host. Vendor product
# shots are copied in rather than hot-linked: a vendor CDN path is theirs to
# reshuffle, and a tile whose picture 404s is worse than one that never had it.
# Set `own_img` (a bare filename) instead of `img` to use one.
# A single custom role for the native-Linux companion, which speaks TCP rather
# than BLE/USB. Custom roles render with a plain label and never map to the
# in-app Configure step -- that is fine for these download-only entries.
CUSTOM_ROLES = {
"companionTcp": {
"icon": "lan",
"title": "Companion",
"subTitle": "TCP",
"tooltip": "Native-Linux companion radio -- connect over TCP.",
}
}
# ---------------------------------------------------------------------------
# Board -> device mapping
#
# `stem` : the exact filename stem build.sh emits (board_clean_for_path).
# `kind` : nrf | esp32 | nrf54l | mg24 | stm32wl | linux -- drives device
# type, file types, extensions.
# `device` : the MeshCore-canonical device name to FOLD into, or a new tile name.
# `new` : True if this device is not in the official catalog (its own tile).
# `img` : filename in MeshCore's own image set (resolved against IMG_BASE).
# `own_img`: filename we ship from this repo's img/ dir (resolved against
# --url-base). Takes precedence over `img`.
# `variant`: optional filename infix (e.g. "noscreen") + shown as subTitle.
# `subtitle`: optional role-row subTitle to disambiguate hardware variants.
