v0.1.0MIT

Use Tern from omp: a tern_lua tool running Lua with Tern's window API (agents, layout, blocks, git, settings) and a tern skill

GitHubOpen Website

piebird-tern-bridge

Let omp work the Tern window it runs in. Ask in plain words: open a file beside you, split a pane and run the tests there, start a Tern agent (omp, Claude Code or Codex in its own pane) and read its answer, name a tab. The tern_lua tool runs Lua with Tern's window API in the window holding omp's pane.

omp opens a file beside itself, then starts a Tern agent and reads its answer

Install

omp plugin marketplace add georgelubaretsi/piebird
omp plugin install piebird-tern-bridge@piebird

The plugin's Tern half (so.stencil.tern/) comes with it: the next time omp starts in a Tern pane, it installs it into Tern and says so in the chat. After omp plugin upgrade it updates it the same way. Turned off in Tern's settings, it is left alone.

What it adds

  • tern_lua: Lua in the Tern window, with cx, the window API Tern's own assistant has. The tool reports a Lua error as an error, and a call that may have run as "outcome unknown".
  • The tern skill: the common calls (panes, files, Tern agents, git, layout), the tern CLI for the rest, and the rules (don't take focus unless asked, close only what you opened).
  • The tern-agents rule: in Tern, read the skill first, and keep omp's own subagents apart from Tern agents in panes.

Requirements

  • Tern on macOS or Linux, omp in a pane on the same machine. Panes on a remote host don't get the tool: Tern never lets a remote host run code in your window.
  • macOS: App Nap off for Tern, or a Tern window in the background is too slow to answer. The tool says so when it's on; the fix is defaults write so.stencil.tern NSAppSleepDisabled -bool YES, then restart Tern.

What the model sees: the tool, the rule and the skill, word for word.
