Fresh Copilot

GitHub Copilot plugin for the Fresh terminal based IDE & text editor.

Provides inline ghost text completions and a chat panel, both powered by the official Copilot Language Server.

Examples

Asking Copilot a question about the open file

Copilot proposing and applying edits directly in the file

Requirements

• Python 3.6+
• Copilot Language Server:

  npm install @github/copilot-language-server

• A GitHub Copilot subscription (free tier works)

Features

• Ghost text completions - suggestions appear inline as you type, accepted with Tab
• Chat panel - ask Copilot questions about the file you have open
• Inline edits - Copilot can edit the file directly from chat, with full undo support
• Status bar indicator - shows connection state and last action
• Sign in/out from inside the editor

Setup

Copy (or symlink) this folder to ~/.config/fresh/plugins/packages/copilot/.

The plugin auto-starts when the language server is found. On first use run Copilot: Sign In from the command palette and follow the browser flow.

Architecture

copilot.ts             - Fresh plugin (UI, keybindings, IPC glue)
copilot_server.py      - LSP bridge for inline completions
copilot_chat_server.py - HTTP chat bridge (talks to Copilot Chat API)

Known Issues

• Space before ghost text - inline suggestions appear with a leading space. This seems to be a quirk in Fresh itself.
• Line numbers visible in chat panel - the chat panel shows line numbers even though none are needed. As there doesn't seem to be a way for plugins to override per-split display settings (Fresh appears to copy them from global config when creating a virtual buffer in a split), this can't be worked around from the plugin side.
• Rulers visible in chat panel - same issue as above.
• Chat panel shows a tab - the panel appears as a regular tab in the tab bar. hiddenFromTabs is not available for createVirtualBufferInSplit, so there is currently no way to hide it.
• Undo applies in two steps - each edit hunk from Copilot chat is a delete followed by an insert, so undoing requires two Ctrl+Z presses per hunk. There is no batch/atomic edit API available in Fresh plugins at this time.
