MingaEditor.Renderer.Context (Minga v0.1.0)

Rendering context for a single render pass.

Bundles the per-frame invariants that every line renderer needs: viewport geometry, visual selection bounds, search match positions, gutter width, and the active substitute-confirm match (if any).

Built once per render call and threaded through the line rendering pipeline, keeping individual function signatures focused on the per-line values that actually vary (line text, screen row, buffer line).

Summary

Types

t()

visual_selection()

Represents the bounds of a visual selection for rendering.

Functions

with_decorations(ctx, decorations)

Returns the context with a different decoration set.

visual_selection()

@type visual_selection() ::
  nil
  | {:char, {non_neg_integer(), non_neg_integer()},
     {non_neg_integer(), non_neg_integer()}}
  | {:line, non_neg_integer(), non_neg_integer()}

Represents the bounds of a visual selection for rendering.

nil — no active selection
{:char, start_pos, end_pos} — characterwise selection
{:line, start_line, end_line} — linewise selection

Functions

with_decorations(ctx, decorations)

@spec with_decorations(t(), Minga.Core.Decorations.t()) :: t()

Returns the context with a different decoration set.
