bencher.plugins.builtins

Built-in chart types wrapped as plot plugins (A1 Phase 2).

Each wrapper delegates to the existing renderer method on the live BenchResult (carried in BenchData.legacy_result), so renderer logic is unchanged — this phase only moves dispatch onto the plugin registry. The registry-level match rule is permissive (PlotFilter.match_all()) because today’s renderers build their shape filters dynamically inside to_plot (scenario lists, over_time special cases) and return None on mismatch; centralizing those filters into declarative signatures is the plot-selection redesign (A2), not this phase.

Priorities encode the legacy default_plot_callbacks() ordering so reports render plots in exactly the same order as before.

Attributes

`PANES_PLUGIN_NAME`
`CALLBACK_TO_PLUGIN`

Classes

LegacyResultPlugin

Thin plugin adapter over a legacy BenchResult renderer method.

Functions

`_declared_kwargs`(→ Optional[frozenset[str]])	The keyword names a fixed-signature callback accepts, or None when it takes
`_builtin_specs`(→ list[tuple[str, str, Callable]])	(name, backend, callback) for the default chart set, in legacy order.
`_named_only_specs`(→ list[tuple[str, str, Callable]])	(name, backend, callback) for chart types that are never auto-selected but can
`register_builtin_plugins`(→ None)	Register the default chart set with the global registry. Idempotent.

Module Contents

class bencher.plugins.builtins.LegacyResultPlugin

Thin plugin adapter over a legacy BenchResult renderer method.

name: str

backend: str

match: bencher.plotting.plot_filter.PlotFilter

priority: int

requires: frozenset[str]

callback: Callable

auto: bool = True

render(data: bencher.plugins.bench_data.BenchData) → panel.viewable.Viewable | None

bencher.plugins.builtins._declared_kwargs(callback: Callable) → frozenset[str] | None: The keyword names a fixed-signature callback accepts, or None when it takes **kwargs or its signature cannot be introspected (no filtering in either case). Deliberately uncached: an lru_cache here would pin every callback — including per-run closures and bound methods with their captured data — for process lifetime, and would crash on unhashable callables.

bencher.plugins.builtins._builtin_specs() → list[tuple[str, str, Callable]]: (name, backend, callback) for the default chart set, in legacy order.

bencher.plugins.builtins._named_only_specs() → list[tuple[str, str, Callable]]: (name, backend, callback) for chart types that are never auto-selected but can be requested by name in plot_list (A1 Phase 3). Plotly appears only where a plot already required it (surface, like volume above); rerun is its own backend and imports the rerun SDK lazily inside the renderer, so registration is safe without the package installed.

bencher.plugins.builtins.PANES_PLUGIN_NAME = 'panes'

bencher.plugins.builtins.CALLBACK_TO_PLUGIN: dict[Callable, str]

bencher.plugins.builtins.register_builtin_plugins() → None: Register the default chart set with the global registry. Idempotent.
