| editor | |
| app | |
| EditorApp.h | RenderSession — the headless sandbox/render-session core used by REPL and tooling. Owns the current document state (URI, raw bytes, rendered bitmap, wire stream) and exposes a narrow state-transition API that higher layers (a REPL, a GLFW/ImGui shell, a wasm frontend) call into |
| EditorRepl.h | RenderSessionRepl is the stdin/stdout-driven command loop that sits on top of RenderSession. It exists so that the sandbox/render-session tooling can be driven (and tested) without an ImGui window — the shell layer is a thin parser that maps line-based text commands to RenderSession methods and writes human-readable output |
| gui | |
| EditorWindow.h | EditorWindow — RAII wrapper around GLFW + OpenGL + Dear ImGui. Keeps the main binary thin by encapsulating everything that would otherwise be boilerplate: GLFW init, window creation, context current, glad loader, ImGui context, imgui_impl_glfw + imgui_impl_opengl3 setup, plus texture upload from a RendererBitmap |
| repro | |
| ReproFile.h | Data model for a .donner-repro file: a recorded sequence of editor UI inputs (mouse events, keyboard events, wheel events, window resizes) plus enough session metadata to re-instantiate the editor and replay the events deterministically |
| ReproRecorder.h | Live UI-input recorder. Install one instance in EditorShell when the user passes --save-repro <path>; call snapshotFrame() once per editor frame (before any UI widgets have consumed input events — right after window_.beginFrame() / ImGui::NewFrame()). On process exit, call flush() to serialize the recording to the destination path |
| sandbox | |
| FrameInspector.h | Headless frame inspection: decode a sandbox wire stream into an indexed list of commands with human-readable summaries, and replay any prefix of those commands into a real backend. This is the engine that S4's eventual ImGui frame inspector panel will sit on top of; keeping it UI-free means we can test it now and reuse it from non-editor contexts (bug reports, .rnr replay CLIs, structural diffs) |
| PipelinedRenderer.h | PipelinedRenderer — a multi-threaded, in-process renderer that reuses the sandbox wire format as a producer/consumer boundary between the main thread (parser + driver + serializer) and a worker thread (deserializer + real backend) |
| ReplayingRenderer.h | Decodes a SerializingRenderer wire stream and dispatches its messages onto a wrapped, real RendererInterface. The replay is host-side: the target can be RendererTinySkia, RendererGeode, or a test mock |
| RnrFile.h | .rnr — Donner Renderer Recording — is a compact on-disk container for a single sandbox wire stream plus enough metadata to reproduce the original render. The file body is the raw wire bytes from SandboxHost::renderToBackend (or SerializingRenderer::takeBuffer) appended verbatim — no re-encoding, no compression |
| SandboxCodecs.h | Encoders and decoders for Donner value types that cross the sandbox wire boundary. Every Encode* writes its type into a WireWriter; every Decode* reads from a WireReader and sets the reader's failure flag on any problem (truncation, invalid variant tag, out-of-range enum, length cap). Decoders never throw and never crash on adversarial input |
| SandboxDiff.h | Structural diff engine for .rnr recordings. Compares two decoded command streams (and their headers) using a longest-common-subsequence alignment, producing a unified-diff-style report suitable for regression triage |
| SandboxHardening.h | Defense-in-depth hardening applied inside the sandbox child process immediately after startup, before it reads any untrusted input. See docs/design_docs/0023-editor_sandbox.md §"Milestone S6" |
| SandboxHost.h | Host-side driver for the sandbox child process. See docs/design_docs/0023-editor_sandbox.md (S1 for the process model, S2 for the wire format, S3 for the host-side replay path) |
| SandboxProtocol.h | Shared protocol constants between the editor host and the donner_parser_child sandbox binary. See docs/design_docs/0023-editor_sandbox.md Milestone S1 for the one-shot byte-in / PNG-out contract these exit codes implement |
| SerializingRenderer.h | SerializingRenderer is a RendererInterface implementation that encodes each virtual method call to a WireWriter instead of rasterizing. It runs the normal RendererDriver inside its draw() entry point, so every call the driver would have made into a real backend (transform stack, paint state, draw primitives) ends up as a wire message |
| SvgSource.h | SvgSource resolves a user-supplied URI into a raw byte buffer that the sandbox child can parse. This is the host-side half of the address bar design: the host has filesystem (and eventually network) privilege, and hands the sandbox child only the resulting bytes — never the filename, never the URL |
| Wire.h | Milestone S2 wire format for the editor sandbox. See docs/design_docs/0023-editor_sandbox.md §"Wire format" |
| AsyncRenderer.h | AsyncRenderer owns a svg::Renderer and runs its draw() + takeSnapshot() on a dedicated worker thread so heavy renders don't block the UI thread |
| AsyncSVGDocument.h | AsyncSVGDocument is the editor-owned wrapper around svg::SVGDocument that gates DOM mutations through the CommandQueue and provides the snapshot hand-off to the render thread described in the M1.5 design note in docs/design_docs/editor.md |
| AttributeWriteback.h | Builds a TextPatch that updates an SVG element's attribute in the source text. This is the bridge between a canvas tool mutation (e.g. a drag that changes transform) and the source pane |
| ChangeClassifier.h | Classifies a text edit as either an attribute-value change on a specific element (fast path → SetAttributeCommand) or a structural change (fallback → ReplaceDocumentCommand). This is the M5 gate: when structured editing is enabled, the main loop calls classifyTextChange instead of unconditionally emitting a ReplaceDocumentCommand |
| ClipboardInterface.h | Abstract clipboard interface used by the editor's text-editor core (see text_editor_refactor.md). Decouples copy/cut/paste from ImGui so headless unit tests can inject an in-memory implementation instead of requiring an ImGui context |
| CommandQueue.h | CommandQueue is the per-frame EditorCommand queue described in the "AsyncSVGDocument: single-threaded command queue" section of docs/design_docs/editor.md. It accumulates editor-initiated DOM mutations on the UI thread and coalesces them at flush time |
| DialogPresenter.h | |
| DocumentSyncController.h | |
| EditorApp.h | EditorApp is the editor's top-level shell — the mutation-seam frontend that tools and the main loop interact with. Owns the AsyncSVGDocument, the active selection, and (eventually) the active tool dispatcher |
| EditorCommand.h | EditorCommand is the discriminated union of every UI-thread→DOM mutation in the M2 scope of the editor. New tools (path, node-edit, etc.) extend this variant in their own follow-up milestones — one new case per logical operation, NOT one per ECS write |
| EditorInputBridge.h | |
| EditorShell.h | |
| ExperimentalDragPresentation.h | |
| GlTextureCache.h | |
| ImGuiBackendIncludes.h | |
| ImGuiClipboard.h | Production ClipboardInterface implementation backed by ImGui's clipboard functions (ImGui::GetClipboardText / SetClipboardText) |
| ImGuiIncludes.h | |
| ImGuiInternalIncludes.h | |
| InMemoryClipboard.h | Header-only in-memory implementation of ClipboardInterface. Stores a single std::string in the object — no OS / ImGui interaction |
| KeyboardShortcutPolicy.h | |
| MenuBarPresenter.h | |
| OverlayRenderer.h | OverlayRenderer draws editor chrome (currently selection path outlines) directly into the renderer's existing frame buffer using the canvas primitives RendererInterface already exposes. It is not a separate compositing layer and not a fabricated SVG subtree — chrome and document share one render target so there is no subpixel drift between them |
| PinchEventMonitor.h | Platform-specific render-pane pinch gesture capture. On macOS this installs a local magnify-event monitor and feeds synthetic zoom scroll events into the existing editor queue |
| RenderCoordinator.h | |
| RenderPaneGesture.h | Headless classification for render-pane scroll gestures. main.cc feeds raw GLFW scroll events into this helper so tests can cover pan vs. zoom routing without depending on ImGui or GLFW |
| RenderPanePresenter.h | |
| SelectionAabb.h | |
| SelectTool.h | SelectTool is the editor's first and (in this milestone) only tool. It dispatches three different gestures off onMouseDown: |
| SidebarPresenter.h | |
| SourceSync.h | Helpers for keeping the source pane, command queue, and DOM parse state in sync when editor-owned code writes bytes back into the text buffer |
| TextBuffer.h | |
| TextEditor.h | |
| TextEditorCore.h | Headless editing substrate for the ImGui TextEditor widget |
| TextPatch.h | The TextPatch type and applyPatches function form the editor's canvas-to-text writeback sideband. When a tool mutates an attribute via EditorApp::applyMutation, it also produces a TextPatch that describes the corresponding byte-level splice in the source text. The main loop drains pending patches after flushFrame() and before rendering the source pane |
| Tool.h | Tool is the abstract interface for editor pointer tools (Select, future Path, future Node-edit, etc.). Tools observe the editor state via the EditorApp& parameter and produce DOM mutations exclusively by calling EditorApp::applyMutation() — they never touch the DOM directly |
| TracyWrapper.h | Conditional Tracy profiling macros for the editor. When ENABLE_TRACY is defined, the real Tracy profiler client is included; otherwise the macros expand to no-ops so editor code can be instrumented unconditionally |
| UndoTimeline.h | |
| ViewportGeometry.h | |
| ViewportInteractionController.h | |
| ViewportState.h | ViewportState is the single source of truth for the editor render pane's screen↔document coordinate mapping. See docs/design_docs/0025-editor_ux.md for the full design rationale; this header is the public API |

| geode_embed_surface.h | Platform-native WebGPU surface creation helper for the geode_embed example. The implementation lives in platform-specific translation units (geode_embed_surface_linux.cc, geode_embed_surface_macos.mm) that include native-window headers (X11, Cocoa) in isolation so their macro pollution — X11/Xlib.h defining None, True, False, Status — never reaches donner headers. The consumer (geode_embed.cc) only sees this small facade |
| geode_embed_surface_macos.mm | MacOS (Cocoa/Metal) implementation of CreateSurfaceFromGlfwWindow |
