Frame.theme (7 presets in app/theme_tokens.py) drives font family,
corner radius, drop shadow, and an accent hue for every modern-style
widget's header/accent region. Rich accent colors (not just the 6 flat
panel inks) are approximated via denser Bayer stippling confined to just
that region (html_render.ordered_dither_regions), so icon/text content
elsewhere stays exactly as crisp as it is today -- verified directly
against real Chromium renders, both in unit tests and via run-server.
"classic" is a byte-identical no-visual-change default: weather's header
keeps its original fixed blue gradient, tasks/calendar keep their flat
THEME_* ink.
Themes are purely stylistic -- battery's charge-level color, calendar/
tasks' per-owner event chips, and text's own per-widget font choice are
never touched.
Extends weather's experimental Chromium+Jinja2 render style to battery,
text, tasks, static image, whiteboard, and calendar (all four view
modes -- agenda/today_tomorrow/week/month), and gives the photos widget
its own genuinely independent palette + dithering strength.
Photos: Frame.photo_palette_rgb/photo_dither_strength (mirroring the
existing palette_rgb/dither_strength), with a second "Photos
configuration" card in Advanced Configuration. widgets/photos.py's
render() quantizes itself against these before returning -- no
render_panel changes needed, since photos is the only widget that
genuinely needs a different reference palette and can carry that
itself, the same way modern-style widgets already self-dither via
ordered_dither.
Battery/text/tasks/static image/whiteboard: same render_style pattern
weather established (render_style column, html_render.py build
function, Jinja2 template, dialog toggle). Static image/whiteboard get
their first-ever visual chrome (a rounded-corner shadowed card,
shared framed_image.html.jinja) since classic draws them with zero
frame at all. Fixed the same "preview endpoint bypasses render_style"
bug weather originally shipped with, for tasks/static/whiteboard/
calendar's preview endpoints.
Calendar: own module (app/calendar_html_render.py, mirroring
calendar_render.py's separation from the simpler widgets) covering all
four view modes, not just agenda -- reuses calendar_render's own
private helpers so event colors/times/weather/month-grid math match
classic exactly. Found and fixed two real cross-day layout bugs along
the way: a per-day header height that varied based on whether that
specific day had a weather entry (misaligning where every other day's
event rows started across the week/month grid), and regular-weight
small text being fragile under Bayer ordered dithering (out-of-month
day numbers degraded into unrecognizable speckle) -- fixed by using
bold everywhere and de-emphasizing via size instead of weight/gray,
since gray text has the same dithering fragility this project's PIL
renderers already avoid for exactly this reason.
Migrations 32-38 (Frame's two new columns, then one render_style column
per widget config table). 452 tests passing, including new dispatch/
migration coverage per widget type and a dedicated photos test proving
photo_palette_rgb produces genuinely independent quantization from the
frame's main palette_rgb.
build-and-push failed on the last deploy: chromium-headless-shell's
single ~181MB binary can't be split across Docker layers the way this
project's pip/npm installs were (those are many independently-
installable smaller packages; this is one file), and confirmed-failed
to push past the registry's per-layer size limit.
Moves the `playwright install chromium-headless-shell` step from the
Dockerfile to start.sh, caching into PLAYWRIGHT_BROWSERS_PATH on the
/data volume -- only the very first boot on a fresh volume downloads
it, every boot after that is a no-op check. The image itself no longer
grows by ~262MB, so nothing new gets pushed to the registry at all.
The weather widget's icons/layout are hand-drawn PIL primitives -- clean
under quantization but flat, no gradients/shadows. Adds an opt-in
render_style="modern" (current/daily modes only) that instead renders a
Jinja2 template through a persistent headless-Chromium browser
(app/html_render.py), following the approach of Tesserae, an open-source
e-ink dashboard targeting this same panel family.
Key design points:
- The Chromium dependency (Playwright) is lazily imported only when a
weather widget actually uses "modern" style, and the background browser
itself only launches on first use -- every other widget type, and this
one's own classic/hourly/multi_city paths, never pay for it.
- No Frame-level dithering setting needed: html_render dithers its own
rendered widget to exact palette colors (Bayer/ordered, not
Floyd-Steinberg) before compositing, so the shared whole-canvas
Floyd-Steinberg pass sees zero quantization error there and leaves it
untouched -- same trick draw_text/hand-drawn icons already use. Floyd-
Steinberg keeps working unchanged for photos and every other widget.
- A "Load calibrated Spectra 6 preset" button in Advanced configuration
offers a community-measured palette (data ported from
paperlesspaper/epdoptimize, Apache 2.0) as an alternative starting
point to the existing idealized DEFAULT_PALETTE_RGB -- fills the
existing palette table, doesn't save by itself.
Known open risk, not resolved here: a headless Chromium binary is far
larger than the ~100MB single-layer limit that already forced this
project's pip/npm installs into split layers, and (unlike those) is a
single ~180MB file that can't be split across layers by ordinary
Dockerfile restructuring. Flagged prominently in server/Dockerfile and
docs/widgets.md -- treat this render style as experimental/local-only
until that's resolved.
Next/back button assignment moves from a frame-level "Button
assignments" card into each widget's own gear-icon dialog, prefilled
with a sane default at creation (photos/calendar -> advance/back,
whiteboard/weather -> check_now, others -> none). At most one binding
per (widget, button) now -- cross-widget execution order never
mattered since each widget's action only touches its own state.
New firmware capability: holding NEXT or BACK past a configurable
duration (min 3s, server-side default) triggers a frame-wide action
instead of the per-widget short-press one -- cycling saved layouts,
refreshing all widgets, or freezing/unfreezing every photo widget (see
app/global_actions.py). Firmware next/back checks gain the same
hold-duration polling the combo button already had; the threshold
comes from the previous wake's /frame/config fetch (persisted in NVS),
since this wake's button decision happens before that request.
Not done here: firmware/version.txt is intentionally left unbumped --
this hasn't been built or hardware-tested (no ESP-IDF toolchain in this
environment), so no firmware release build should be triggered yet.
A "Lock this photo" button in the photos widget's dialog toggles
PhotoWidgetConfig.locked, which suppresses both the timer-elapsed
auto-advance and the advance/back button actions until unlocked. The
Layout tab canvas shows a lock badge on any locked photo widget's box.
A Widget-level property (border_style/border_thickness/border_color_index),
not a per-type config field, since every widget type can have one -- drawn
once centrally in device.py's _render_widgets before compositing, using
an exact panel palette color so it never dithers. Styles: solid, dashed,
dotted, and a fancy double-line picture-frame-mat look. Configurable from
a shared "Border" card in every widget's gear-icon dialog.
Shows Frame.battery_percent/battery_as_of, already set by every device
wake-on-battery report, plus routers/common.py's existing
battery_estimate_s time-remaining estimate -- nothing new to fetch or
cache. Compact (icon + percent) or detailed (+ estimate, last report
age) display mode. No button actions.
The vendored EC bitmaps looked good but dither into a visible speckle
once quantized to the panel's 6-color palette (their colors are
anti-aliased/arbitrary RGB, essentially never an exact palette match).
Hand-drawn icons filled with the frame's actual ink colors quantize with
zero dithering error to diffuse -- confirmed by running both through the
real quantize pass: the bitmap version speckles, the hand-drawn one is
pixel-identical before and after.
Redrawn to look more like EC's style this time around: pointed
triangular sun rays (the earlier attempt's thin-line rays read as a
crosshair, not a sun) and dendrite snowflakes (tick marks near each tip,
not a bare asterisk), plus the same cloud/raindrop/lightning-bolt shapes
as before. Removed the vendored server/app/weather_icons/ directory
entirely -- no longer used, and removes the icon-image licensing
question along with it.
The hand-drawn glyphs (draw_cloud/draw_sun/draw_raindrop/draw_snowflake/
draw_lightning_bolt) are replaced by 7 vendored bitmaps, one per shared
weather category, sourced from weather.gc.ca's public icon set -- these
are small, flat-shaded images that dither cleanly onto the panel's
6-color palette and read as recognizable weather icons in a way the
hand-drawn attempt (a plain circle-with-ticks "sun") didn't. Used for
every provider's rendering (Open-Meteo, NWS, EC), not just when EC is
selected.
Vendored (not fetched live at render time), matching this project's
existing convention for the Noto Emoji fonts -- server/app/weather_icons/
SOURCE.md documents the source, attribution, and the licensing caveat
(this is a personal, non-commercial project; the icon images' own
copyright terms are less clearly permissive than the weather data's own
End-use Licence, since they're served from the public website rather
than ECCC's data servers).
draw_weather_icon's signature changes from (draw, cx, cy, r, category,
palette_rgb) to (img, cx, cy, r, category): pasting a bitmap needs the
Image object, not just an ImageDraw handle, and palette_rgb is no longer
needed since the shared _quantize step already maps whatever's on the
composited canvas to the frame's actual palette -- no per-icon color
resolution required anymore.
app/weather/ec.py -- api.weather.gc.ca's MSC GeoMet OGC API
(citypageweather-realtime collection), the modern replacement for the
old dd.weatheroffice.gc.ca XML feed (that host no longer resolves).
Unlike Open-Meteo/NWS's simple lat/lon REST, this collection is only
queryable by bounding box, so _nearest_site widens the box
progressively and picks the closest of the ~844 sites by straight-line
distance -- capped at 300km, calibrated against a real bug caught in
development where an unconditional "nearest site, however far" matched
a Miami, FL query to a site in Ontario 1824km away once the box widened
to cover the whole country.
EC's own numeric icon codes get a small confirmed-against-live-data
mapping table plus the same keyword-on-condition-text fallback NWS
already uses for anything unmapped. Daily periods are named ("Today"/
"Tonight"/"Tuesday"/...) rather than dated, so dates are inferred by
walking them in issued order.
Verified end-to-end against the real live API (Toronto, rural
Saskatchewan, a US border city, and a rejected far-away match) and
through the browser (daily mode, composited panel preview). Test
fixtures mirror the actual response shapes captured live. docs/
widgets.md and CLAUDE.md's TODO updated -- EC is no longer a documented
gap.
New widget type with four display modes -- current conditions, an
hourly forecast strip, a multi-day forecast, and several cities' current
day side by side -- backed by a pluggable provider registry (app/weather/,
mirroring the app/widgets/ dispatch pattern): Open-Meteo (worldwide) and
NWS (US-only) both wired up now, Environment Canada documented as the
next one to add given its more involved station/grid-lookup API.
The calendar widget's existing embedded weather strip is untouched and
still Open-Meteo-only; this lifts the same underlying icon-drawing
primitives (now shared via app/weather_render.py, calendar_render.py
still imports draw_weather_row unchanged) into a widget that can be
placed and sized on its own. Icons are redrawn in the panel's actual ink
colors (yellow sun/bolt, blue rain/snow) instead of flat black, and
build_multi_city's icon/font sizing now scales with how many cities need
to fit rather than the box's height alone -- both fixed after catching
them via live browser verification, along with a mode-switch cache-shape
crash and a mobile-width dialog overflow.
New WeatherWidgetConfig table (migration 24), grid footprint, widget
module, common.py fetch/cache helper, router endpoints (location set/
clear, city add/remove, preview), dialog template + JS, and full test
coverage (providers, widget render, HTTP endpoints, migration replay).
docs/widgets.md and CLAUDE.md's TODO updated accordingly.
A new self-contained widget type showing user-authored rich text -- no
live upstream to poll, like the static image widget, just word-wrapped
styled text instead of an uploaded image.
The dialog's contenteditable HTML is never stored or replayed as HTML:
app/text_content.py parses it server-side (on save) into a plain
paragraphs-of-styled-runs structure -- the actual sanitization
boundary, since raw HTML never round-trips back into any browser DOM
(the dialog rebuilds its editor from that same JSON via
createElement/textContent). app/widgets/text.py renders it with a
custom word-wrap/shrink-to-fit layout, using real vendored font weights
(app/fonts/NotoSans-{Regular,Bold,Italic,BoldItalic}.ttf, OFL-licensed
like the emoji fonts already there) rather than every other widget's
single ImageFont.load_default() -- the one widget type where that
distinction matters.
The static-image widget shipped without updating docs/widgets.md's
per-type enumeration -- fixed, and added a skill encoding the full
file-by-file checklist a new widget type touches, so future ones (a
text widget is next) don't repeat either gap.
Tasks widgets could only ever point at one CalDAV task list (a radio-
button picker, owner-only). Now they merge any number of included task
lists across every linked user, same checkbox-inclusion + optional
pinned-color shape a calendar widget already has for its calendars --
FrameTaskList mirrors FrameCalendar exactly, down to the same owner-
adds/anyone-mutes permission split (api_widget_task_list_select/
api_widget_task_list_color). Reused calendar_render._event_colors/
_draw_color_bar as-is for the per-task color bar -- a task dict's
owner_display_name/color_index is exactly that function's single-
source fallback shape.
Also added an opt-in "show tasks completed in the last 24 hours"
toggle (TaskWidgetConfig.show_completed): caldav_client.fetch_tasks
now accepts a completed_since cutoff and returns completed VTODOs
(with their completion time) instead of silently dropping them, and
_draw_tasks gives a completed task a filled checkbox + muted text
instead of the normal empty-box/due-date row.
Migration 18 splits the single-source TaskWidgetConfig columns
(added by 17, splitting tasks out of the calendar widget in the first
place) into frame_task_lists, carrying forward each widget's existing
single source as its first included list -- same shape migration 9
used carrying forward frame_calendars' old single opt-in.
Verified live in the browser (desktop + mobile): the new "Included
task lists" + "Recently completed" dialog sections, the show_completed
toggle actually persisting through a real HTTP round-trip, and no
regression in the calendar widget's own "Included calendars" dialog.
Full suite (192 tests, including new merge_tasks/config_save/migration
coverage) passes.
Task lists used to be a week-view-only sub-feature bolted onto calendar
widgets (CalendarWidgetConfig.tasks_*), so a task list could only exist
tied to a calendar's view and only inside its footprint. Tasks are now
a standalone widget type (TaskWidgetConfig, app/widgets/tasks.py) that
can be placed and sized independently, same as photos/calendar/
whiteboard -- no separate "enabled" flag either, since being on the
grid at all is the on/off switch, matching every other widget type.
Migration 17 creates task_widget_configs, extracts any existing
calendar widget's configured task source into a new sibling tasks
widget (auto-placed in open grid space, source dropped+logged if truly
none is left), then drops calendar_widget_configs' now-dead tasks_*
columns in the same migration -- this project's usual same-migration-
drop convention. Also handles the rarer case of a database jumping
straight from before the widget system existed to after this split in
one boot, via the legacy Frame.calendar_tasks_* columns.
Verified live in the browser at desktop and mobile widths: adding a
Tasks widget, its own dialog (task-list source picker + preview), and
confirming the calendar widget's dialog no longer mentions tasks at
all. Full test suite (180 tests, including new coverage for the widget
render/actions, the migration's data-extraction path, and the
permission-boundary shape for tasks-source) passes.
Repo-tracked context so a fresh Claude Code session (this machine or a
remote/cloud one) gets accurate project context without relying on this
session's local, machine-specific memory: repo conventions (no
co-author trailers, flag copyleft deps explicitly, scope security
gates broadly -- each backed by a real past incident), testing/deploy
workflow, and pointers into the existing docs.
docs/architecture.md's sequence diagram and boot-flow text still
described the pre-widget-system single-photo-queue model (e.g. "force-
advance to next queued photo") even though that was fully replaced by
the widget system across this branch's recent history -- fixed, and
added docs/widgets.md distilling the widget system's actual design
(data model, grid placement, compositor, button-action dispatch) as
current-state documentation, including the still-open Phase 6 cleanup
(legacy Frame columns not yet dropped) as a known gap.
