feat: universal element style system — resolver, schema expansion, live preview (#394)
* feat(element-style): universal per-element style resolver One shared implementation of the three things every customizable plugin re-invented: a font loader, the customization.layout x/y-offset reader, and the "did the user actually override this font?" check. The override check is the load-bearing piece: the web UI's save flow writes full schema defaults into config.json on every save, and the plugin manager merges defaults again before instantiation, so key presence never means user intent. The resolver compares against the plugin's own schema defaults (via schema_manager), degrading to caller-supplied classic defaults when unavailable. This retires the hand-maintained _CLASSIC_FONT_DEFAULTS dicts that shipped broken twice. The loader is a superset of the four per-plugin variants: alias resolution (baseball), truetype for TTF/OTF/BDF (FreeType loads BDF at native size), .pil sidecar fallback for BDF (football), fallback font, PIL default — never raises. Also introduces the text_color convention ([r,g,b], absent = keep the plugin's hardcoded color). BasePlugin gains a lazy style_resolver property (invalidated on config change) and element_style() sugar; standalone helpers receive the resolver from their owning plugin.

SchemaManager.load_schema expands declarations before caching, so the config form, save path, validation, and defaults generation all see the same shape; the single expansion implementation lives in src.element_style and is also applied by defaults_from_schema_file, keeping the web UI's view and a plugin's raw-schema-file view of the defaults provably identical (parity test). Generated blocks use only widgets the config form already renders (font-selector, color-picker, number inputs) and update x-propertyOrder when present (the template only renders listed keys). Expansion is idempotent, never mutates its input or the cached/on-disk schema, and a hand-written block for the same element always wins. Color gets the same provenance rule as fonts: the web form always posts the RGB inputs, so a saved config carries the schema-default color whether or not the user touched it — the resolver now only honors a color that DIFFERS from the schema default, and keeps the plugin's classic (possibly state-dependent, e.g. gold-on-touchdown) color otherwise. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FqzC1nzTWL4kaqgMaQZFam * feat(web): live plugin preview on the config page Adds POST /api/v3/plugins/preview: renders a plugin headlessly with the CANDIDATE (unsaved) config and returns a PNG — so users can see exactly what the panel will show before saving, at their real panel size (from display.hardware) or a chosen test size. Two extractions make it drift-proof rather than parallel-implemented: - dev_server's _render_once moves to src/plugin_system/testing/render_service.py (pure PIL via VisualTestDisplayManager, install_deps=False always — safe in the web process, which never touches display hardware); the dev server now wraps it. - save_plugin_config's ~350-line form->config conversion is extracted verbatim as parse_plugin_config_form and shared by the preview endpoint, so preview and save can never interpret the form differently. update() is skipped by default (no network on the request thread); plugins with a test/harness.json get their mock-data fixture primed instead, and ?skip_update=0 opts into a live update. The config page gains a Live Preview panel (HTMX hx-include of the existing form, size selector, pixelated img fragment) — works for every plugin with zero per-plugin code, including the x-style-elements font/size/color fields. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FqzC1nzTWL4kaqgMaQZFam * fix(web): expand x-style-elements in the config-page form render too pages_v3's plugin-config partial loads config_schema.json directly from disk rather than through SchemaManager.load_schema, so declared style elements expanded everywhere EXCEPT the form the user actually sees. Found live on the devpi: the API served the expanded schema and the save path validated against it, but the config page rendered no font/color/offset fields. Apply the same (idempotent) expansion here. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FqzC1nzTWL4kaqgMaQZFam * fix(web): preview size selector — htmx caches hx-post, use hx-vals Found live on the devpi: selecting a preview size did nothing because htmx snapshots the request path when it processes the button, so the size dropdown's onchange mutation of hx-post never took effect. The size now travels as a __preview_size=WxH form field attached via hx-vals (evaluated at request time); the endpoint honors it (query args still win for API callers) and strips it before form parsing so it can't leak into the candidate config. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FqzC1nzTWL4kaqgMaQZFam * fix(web): allowlist plugin_id in the preview endpoint's dir lookup Same defense as the dev server's find_plugin_dir (and pages_v3's existing pattern): plugin_id arrives in request input and is used to build filesystem paths — reject anything outside ^[a-zA-Z0-9_-]{1,64}$ before touching the filesystem. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FqzC1nzTWL4kaqgMaQZFam * fix: harden preview + resolver edges found in self-review - extract_schema_defaults now matches SchemaManager's array handling ([] for arrays without defaults, [item] for item-level defaults) — the documented parity guarantee was false for array-typed properties; parity test extended to cover them. - render_plugin_once calls plugin cleanup() in a finally (image captured first — cleanup may clear the canvas): preview instances could leak sessions/threads per request in the long-running web process. - Preview JSON path deep-merges the candidate onto the saved config, matching the form path — a shallow update() silently dropped saved sibling values in any nested section the candidate touched. - Preview render is bounded (15s, 504 on timeout, daemonized worker): a hanging plugin display() no longer pins a web worker forever. - ElementStyleResolver.is_for(config): public staleness check for callers that cache a resolver, instead of poking _config. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FqzC1nzTWL4kaqgMaQZFam * fix(render-service): adopt the dev server's exception-detail policy Port c6962701's convention into the shared render service (which supersedes the inline _render_once it patched): full tracebacks to the server log via exc_info, only the exception class name to the client.

"""Universal per-element style resolution for plugin customization.
|
||||
|
||||
Plugins expose per-element user customization under ``config['customization']``:
|
||||
|
||||
"customization": {
|
||||
"score_text": {"font": "PressStart2P-Regular.ttf", "font_size": 10,
|
||||
"text_color": [255, 255, 255]},
|
||||
"layout": {"score": {"x_offset": 2, "y_offset": 0}}
|
||||
}
|
||||
|
||||
Before this module, every plugin re-implemented the same three pieces —
|
||||
a font loader, an x/y-offset reader, and (for adaptive layout mode) a
|
||||
"did the user actually override this?" check. The loaders diverged four
|
||||
ways across the sports plugins and music, the offset reader was copied
|
||||
twice, and the override check is subtle enough that it shipped broken
|
||||
twice: the web UI's save flow (schema_manager.merge_with_defaults) writes
|
||||
the FULL schema default object into config.json on every save, and the
|
||||
plugin manager merges defaults into ``config`` again before instantiation,
|
||||
so a key being *present* never means the user set it. The only correct
|
||||
test is "present AND different from the schema default", which requires
|
||||
knowing the schema defaults — previously a hand-maintained dict per plugin.
|
||||
|
||||
This module is that logic, once:
|
||||
|
||||
resolver = ElementStyleResolver(config, schema_defaults)
|
||||
style = resolver.style('score_text', classic_font='PressStart2P-Regular.ttf',
|
||||
classic_size=10)
|
||||
style.font # loaded PIL font, ready for draw.text
|
||||
style.user_forced # True only for a genuine user override
|
||||
dx, dy = resolver.offset('score')
|
||||
|
||||
``BasePlugin.element_style()`` wires this up automatically (schema defaults
|
||||
come from the plugin's own config_schema.json via the schema manager).
|
||||
Standalone helper classes (e.g. a plugin's GameRenderer) should receive a
|
||||
resolver from their owning plugin rather than build one themselves.
|
||||
|
||||
Deliberately pure PIL + stdlib: no imports from the plugin system or web
|
||||
layer, so it is usable from any renderer and trivially testable.
