lsp_ui

LSP UI mount panel — composes the Z.lsp.* widgets with state + polling + Z.app lifecycle. Mount it from any scene/component to get a tabbed Diagnostics / Docs / Settings panel that stays fresh on its own. This is Layer B in the stack: Layer A's widgets stay pure builders under Z.lsp.*, Layer C (system_tools) embeds those widgets inside its existing tab strip, and Layer B turns them into a standalone window with state + polling.

Exports

• M.mount(opts: MountOpts?) -> LspUiHandle — mount the panel, return a handle whose update / onCallback / destroy / setVisible the caller drives each frame.

Types:

• MountOpts = { title: string?, refreshIntervalMs: number?, initialTab: string?, layer: string?, showAsWindow: boolean? }
• LspUiState = { ...activeTab, diagnostics, summary, namespaces, methods, ... } — the live state map shared between update and onCallback.
• LspUiHandle = { state: LspUiState, update: (dt) -> (), onCallback: (id, data) -> boolean, destroy: () -> (), setVisible: (b) -> (), screenName: string }

Usage

local LspUi = require("@builtin::modules.engine.editor.lsp_ui")

local handle = LspUi.mount({
    title = "LSP",
    refreshIntervalMs = 1000,
    initialTab = "diagnostics",
})

-- In your component:
function update(dt) handle.update(dt) end
function onCallback(id, data) return handle.onCallback(id, data) end
function onDestroy() handle.destroy() end

Notes

• mount primes namespaces and strict-mode synchronously so the first frame isn't a blank shell; polling thereafter is gated on the active tab and the refreshIntervalMs clock.
• showAsWindow = false returns the body widget unwrapped — useful when embedding into another panel.
• The handle's state field is the live reactive state; treat it as opaque except where documented.
