Module defined in lua/common/extensions/ui/imguiWire.lua. ImGui wire protocol - serializes ImGui draw commands into a buffer for remote/deferred execution. Enables ImGui rendering across process boundaries.

Exports

Functions

M.clear()

Clear the accumulated draw command buffer.

Internal Notes

  • generateId(t, idCache) creates unique IDs for ImGui elements, uses caching
  • funcWrap(name) wraps ImGui function names for serialized dispatch
  • execute(buf) replays serialized ImGui commands from a buffer
  • Known issue: swallows nil arguments (e.g., ProgressBar(0.4, nil, "FOO") becomes ProgressBar(0.4, "FOO"))
  • Used for cross-context ImGui rendering (e.g., flowgraph editor)

ui/imguiUtils Reference

Module defined in `lua/common/extensions/ui/imguiUtils.lua`. Higher-level ImGui widget utilities - dropdowns, key-value tables, recursive tree displays, texture objects, and sampled float displays.

ui/improfiler Reference

Module defined in `lua/common/extensions/ui/improfiler.lua`. ImGui-based LuaJIT profiler visualization - renders profiling data as an in-game overlay using ImGui.
