08265c1135 feat(vegas): let live content keep its place in the ticker (#457)
* feat(vegas): let live content keep its place in the ticker

Live content used to preempt Vegas outright: while any plugin reported
live priority the display controller refused to run the ticker at all and
showed a full-screen scoreboard instead. Keeping the marquee meant not
seeing live scores; seeing live scores meant losing the marquee.

Two changes, both off by default.

vegas_scroll.live_in_ticker keeps the ticker running through a live game.
Three places assumed the takeover and all three now honour it: the
controller's gate, the coordinator's per-frame pause, and the rotation
switch that would otherwise move current_mode_index underneath a ticker
that never yields.

And the rotation is no longer a strict round robin. It was one slot per
plugin per cycle, so with a dozen plugins enabled a live score came round
once a lap and could be minutes old on screen. A plugin can now hold
several slots, placed by Smooth Weighted Round-Robin -- the same
scheduler the sports plugins already use to rotate their own games. The
property that matters is that repeats are spread through the cycle
rather than clumped: three in a row and then silence would be worse than
no boost at all.

Weight comes from the plugin first, via a new optional
get_vegas_priority_weight(), then from the core: live content earns
live_weight, everything else 1. So existing plugins gain the behaviour
without changes, and the hook exists for the one thing the core cannot
work out -- the core can see that a game is live but not whose, so only
the plugin can say a favorite is playing.

Documented in ADVANCED_FEATURES (worked example, why weights are per
plugin not per game, and that frequency is not freshness),
CONFIG_REFERENCE, PLUGIN_API_REFERENCE, and the config template.

* fix(vegas): carry the new keys through config, and correct two docs

Three findings from CodeRabbit, all valid.

to_dict() and update() enumerate keys explicitly and had not learned the
three new ones, so get_status() never reported them and a live config
change never applied -- turning live_in_ticker on in the web UI would
have done nothing until a restart. update() clamps the weights exactly
as from_config does.

The vegas_scroll key count in ADVANCED_FEATURES said 29; the template
has 30. My arithmetic, not the reviewer's.

The third was a documentation error rather than a code one, and I have
fixed it the other way round. The docs claimed a raising
get_vegas_priority_weight() is treated as weight 1. The code instead
falls through to the core's own live-content check, and that is the
better behaviour: the hook is only how a plugin asks for *more* than
live_weight, and has_live_priority/has_live_content are separate methods
guarded separately, so a plugin with a broken weight calculation should
lose the favorite distinction and keep the live boost. Said so in the
code, the base-plugin docstring and the API reference.

The test fake now fails in each place independently, because the two
failures mean different things: a broken hook still earns live_weight, a
plugin that cannot say whether it is live has nothing to fall back on
and weighs 1.

* fix(vegas): stop the heaviest plugin doubling across the cycle seam

Smooth Weighted Round-Robin spaces repeats well within a pass, but it
schedules the heaviest item first and usually last as well. The strip
loops, so those two are neighbours: the marquee showed the same plugin
twice running at exactly the one join a within-cycle check cannot see.
Observed on a live rig at 28 slots -- gaps of 6, 7, 7, 7 and then 1.

Rotating the list does not fix it. Rotation preserves the cyclic order
exactly, so it moves where the seam is drawn rather than the adjacency
itself; the trailing entry has to be swapped with one from the middle.

The first version swapped with the first slot that merely fitted, which
undid the spacing this exists to protect -- it moved a repeat from a gap
of 7 into a gap of 2, more clumped than the seam had ever been. It now
picks the candidate furthest from any other appearance, so the repeat
lands in the widest gap.

Left alone when no candidate exists. A plugin holding most of the slots
has to neighbour itself, and scheduling it is better than refusing to.

* fix(vegas): stop the seam repair creating the duplicate it removes

Swapping the trailing repeat with a middle slot moves two elements, and
the candidate filter only guarded one of them. It checked the neighbours
`repeated` would acquire at j, but not what the displaced element would
sit beside at the end -- so ['a','b','c','d','x','y','x','a'] came back
as [...,'x','x'], the seam duplicate traded for a fresh one. Reported by
CodeRabbit with that exact case.

Adding the missing condition fixed it and immediately broke something
else: schedule[j] is schedule[-2] when j is the second-to-last slot, so
that candidate was always excluded, and ['a','b','c','a'] lost the only
repair it has. The same class of mistake twice, from reasoning about
which neighbours two moved elements end up with.

So it no longer reasons. It performs each candidate swap, counts the
cyclic duplicates in the result, and keeps the best one that has none --
preferring whichever leaves the boosted plugin most evenly spread. When
no such swap exists the schedule is returned untouched, which is the
unavoidable case: a plugin holding most of the slots has to neighbour
itself.

Fuzzed across 6,956 seam schedules: none made worse, none lost an entry.

Raw Blame History

Configuration Reference

Every key in config/config.json, what it does, its default, and where the code reads it. The file is created from config/config.template.json on first run, and ConfigManager._migrate_config() merges any template keys added by later releases into your existing config (your values are never overwritten). Secrets live in config/config_secrets.json and are merged into the config at load time.

Most settings are editable from the web interface; this page documents the underlying keys for people editing config.json directly or writing tooling against it.

Top level

Key Type / default Meaning Read by
web_display_autostart bool, true Whether the web interface service starts with the system scripts/utils/start_web_conditionally.py
timezone string, "America/New_York" IANA timezone for schedules and displays ConfigManager.get_timezone()
target_fps int, 100 Frame-rate ceiling for plugin rendering src/plugin_system/base_plugin.py, src/common/sports_scroll.py
location object city / state / country, offered to plugins that need a location (weather, etc.) plugins via merged config

schedule — display on/off hours

Key Type / default Meaning

dim_schedule — scheduled brightness dimming

Same shape as schedule, plus:

Key Type / default Meaning
dim_brightness int, 30 Brightness percentage applied while the dim window is active

Read by DisplayController (src/display_controller.py around line 770; saved via POST /api/v3/config/dim-schedule). The display returns to display.hardware.brightness outside the window.

display.hardware — matrix panel hardware

All keys map to the corresponding rpi-rgb-led-matrix options and are read in DisplayManager (src/display_manager.py, ~lines 270295).

Key Type / default

orientation string, "normal""180" rotates the rendered image 180° for panels physically mounted upside down (e.g. to move the Pi/wiring to a more convenient side); composed onto pixel_mapper_config as a trailing Rotate:180 mapper, so it stays independent of any custom pixel_mapper_config value
row_address_type int, 0 — non-standard panel row addressing
multiplexing int, 0 — panel multiplexing scheme
panel_type string, "" — set to "FM6126A" or "FM6127" for panels needing init

Where "code default" differs from the template value, the code default only applies if the key is missing entirely from your config.

display.runtime

Key Type / default Meaning
gpio_slowdown int, 3 GPIO timing slowdown for faster Pis
rp1_rio int, 0 RP1 RIO mode on Pi 5 (applied only if the installed matrix library supports it)

display.double_sided

Drives _LogicalMatrix in src/display_manager.py — renders the same logical image to multiple chained physical panels.

Key Type / default Meaning

Plugin config blocks

Every installed plugin stores its settings under a top-level key equal to its plugin id (the template ships one for the bundled web-ui-info plugin). The shape of each block is defined by that plugin's config_schema.json; common keys are enabled and display_duration. See PLUGIN_CONFIG_CORE_PROPERTIES.md.

config/config_secrets.json

Key Meaning
github.api_token Optional GitHub token the Plugin Store uses to avoid API rate limits (src/plugin_system/store_manager.py:348)
