wesleysimplicio 8e3cfdfb61 fix(webui): allow native text selection in chat via xterm.js bypass (#25720)
The chat panel renders via xterm.js, and when the inner Hermes TUI
enables mouse-events mode (CSI ?1000h family — used for nav inside
Ink overlays/pickers) every drag/double-click/triple-click in the
canvas is consumed by the terminal instead of producing a native
text selection. The reporter (macOS, Brave) confirmed:

- click-and-drag selects nothing
- Cmd+C with no selection copies the entire visible buffer
- existing CSS overrides and event handlers at the document layer
  have no effect — the issue is at xterm.js's mouse layer, not the
  DOM

Fix: two xterm.js options the user can opt into without disabling
mouse-events mode for the inner TUI:

- `macOptionClickForcesSelection: true` — holding Option (macOS)
  or Alt (Linux/Windows) during a click-and-drag bypasses mouse-events
  mode and produces a native xterm selection. This is the documented
  xterm.js path for this exact scenario. Selected text is copyable
  via Cmd+C / Ctrl+C through the existing OSC 52 + manual handlers.
- `rightClickSelectsWord: true` — right-click highlights the word
  under the pointer. Single-action path on top of the modifier-based
  bypass.

The two options coexist with the existing `macOptionIsMeta: true`
(which only affects keyboard, not mouse). No other code change
needed.

Fixes #25720.

Hermes Agent — Web UI

Browser-based dashboard for managing Hermes Agent configuration, API keys, and monitoring active sessions.

Stack

  • Vite + React 19 + TypeScript
  • Tailwind CSS v4 with custom dark theme
  • shadcn/ui-style components (hand-rolled, no CLI dependency)

Development

# Start the backend API server
cd ../
python -m hermes_cli.main web --no-open

# In another terminal, start the Vite dev server (with HMR + API proxy)
cd web/
npm run dev

The Vite dev server proxies /api requests to http://127.0.0.1:9119 (the FastAPI backend).

Build

npm run build

This outputs to ../hermes_cli/web_dist/, which the FastAPI server serves as a static SPA. The built assets are included in the Python package via pyproject.toml package-data.
