4. Live commands

The imgui_node_editor_live module registers project-agnostic [live_command] functions. Each takes a JSON object with editor — the editor handle (intptr(ctx), surfaced in the node_editor snapshot payload) — plus the fields below, and drives the matching boost v2 entry point. So an external driver (dastest, the MCP live API, a tool) can manipulate any editor with no app-side plumbing. Commands are auto-discoverable at runtime via the live /commands endpoint; require imgui/imgui_node_editor_live to register them. This module has no daslang-callable API of its own — it is the JSON drive surface for the boost layer.

Command	Input fields (besides editor)	Effect

clear_selection_cmd	—	Clear all selection.
add_link_cmd	from, to (pin ids)	Queue a new link for the editor to create next frame.
clear_pending_links_cmd	—	Drop all queued (not-yet-created) links.
new_node_drag_cmd	from (pin id), x, y	Inject a “new node by drag” release; fires the app’s create-node flow.
delete_node_cmd	id	Queue a node deletion (cascades pins / touching links via the app).
delete_link_cmd	id	Queue a link deletion.
clear_pending_deletes_cmd	—	Drop all queued deletions.
flow_cmd	id, backward (optional)	One-shot data-flow pulse along a link.
center_node_cmd	id	Center a node in the viewport.
navigate_to_selection_cmd	zoom_in (opt), duration (opt)	Pan / zoom to frame the current selection.
restore_node_state_cmd	id	Restore a node’s saved position / size from editor settings.
set_node_z_cmd	id, z	Set a node’s draw order (higher draws on top).
set_group_size_cmd	id, w, h	Resize a group node.
ordered_node_ids_cmd	—	List node ids in draw order; returns count + ids.
shortcut_cmd	kind (cut / copy / paste / duplicate / create_node)	Inject a clipboard / edit shortcut, replayed through the app’s accept handler.
clear_pending_shortcuts_cmd	—	Drop all queued shortcuts.
enable_shortcuts_cmd	on	Enable / disable clipboard / edit key chords.
