Oh My Pi Chat

A VS Code extension that gives Oh My Pi (omp) a Copilot / Cursor-style chat sidebar.

It launches a local omp --mode rpc session and streams replies, thinking, and tool activity into a modern webview chat UI.

Features

Multi-tab chats (each tab is its own omp session)
Right-click a chat tab to view / export / copy the full session as plain text
Restores all open omp chat tabs/sessions after VS Code restarts or force-quits
History button lists all past omp sessions for the workspace and can resume any of them
Model picker button (lists omp models --json, restarts session on change)
Per-session context usage meter from omp get_state.contextUsage
Activity-bar Chat sidebar (Copilot-like)
Streaming assistant responses over omp RPC
Collapsible thinking blocks
Live tool call cards
Attach current file / selection from the editor context menu
New chat, stop generation, restart session
Settings for model, thinking level, approval mode, auto-approve

Prerequisites

Install Oh My Pi so omp is on your PATH
Configure provider auth the same way you do for the terminal CLI
VS Code 1.90+

npm install
npm run build

Then press F5 (Run Extension) to open an Extension Development Host.

Settings

Setting	Meaning
`ompChat.ompPath`	Path to `omp` (default: `omp`)
`ompChat.model`	Model override (fuzzy match)
`ompChat.thinking`	Thinking level
`ompChat.approvalMode`	`always-ask` / `write` / `yolo`
`ompChat.autoApprove`	Pass `--auto-approve`
`ompChat.continueLastSession`	Restore all open omp chat tabs/sessions on start (default on; survives VS Code kills)
`ompChat.extraArgs`	Extra CLI args
`ompChat.showThinking`	Show/hide thinking blocks in UI
`ompChat.logFileTouches`	Log edit/write/delete touched paths to OMP File Touches output channel

Quick error log: Command Palette → OMP: Show Error Log (also in the chat ⋯ menu). Entries persist across reloads and auto-clear after 7 days.

Architecture

VS Code extension host
  └─ ChatViewProvider (webview sidebar)
       └─ SessionManager
            └─ OmpRpcClient
                 └─ spawn: omp --mode rpc --cwd <workspace>
                      stdin/stdout: newline-delimited JSON

Prompt command:

{ "type": "prompt", "message": "..." }

Stop command:

{ "type": "abort" }

Package

npm run package

This produces a .vsix you can install with:

code --install-extension oh-my-pi-chat-0.1.0.vsix

Notes / roadmap

Interactive omp questions (extension_ui_request: confirm / select / input / editor) render above the composer
Edit/write/delete file touches are logged to the OMP File Touches output channel (OMP: Show File Touch Log)
Tool auto-approval still uses approvalMode / autoApprove (separate from question cards)
Multi-workspace root picker and inline apply/diff are natural next steps
ACP (omp acp) is an alternative transport; this extension uses native --mode rpc for richer streaming events

Attachments

Click 📎 / Files / Folder in the composer
Type @ in the composer to attach a file or entire folder
Paste an image from the clipboard into the input
Drag & drop files onto the chat panel
Right-click in Explorer → OMP: Attach to Chat

Attachments are sent to omp as @/absolute/path mentions (images/files/folders), except code selections which are inlined.
