CodeTime for Zed

Automatic coding-time tracking for codetime.dev, ported from codetime-vscode.

Open files in Zed and your activity (project, language, file, git branch/origin, read vs. write) is reported to the CodeTime API. View the stats on your dashboard.

How it works (and what's different from VS Code)

Zed extensions cannot subscribe to editor events or draw a status-bar item the way the VS Code API allows. The only hook into editing activity that Zed exposes to extensions is the language server protocol. So this project ships two parts:

Part	Crate	Role
Zed extension	codetime-zed (WASM)	Registers and launches the language server for every language.
Language server	codetime-ls (native)	Receives didOpen/didChange/didSave, POSTs event logs to the CodeTime API.

Consequence: there is no in-editor status bar with your total time — that VS Code feature has no Zed equivalent. Tracking (the core feature) works the same.

Configuration

If you have already signed in with another CodeTime client (the CLI, the VS Code extension, …), a token is in ~/.codetime/config.json and this extension picks it up automatically — no setup needed.

To set it explicitly, get your token from codetime.dev and add it to Zed's settings.json:

{
  "lsp": {
    "CodeTime": {
      "initialization_options": {
        "token": "<your-token>"
      }
    }
  }
}

The token is resolved in this order, first match wins:

1. initialization_options.token in settings.json (above)
2. the CODETIME_TOKEN environment variable in the shell Zed inherits
3. the token field of ~/.codetime/config.json

Optional key under initialization_options: api_url overrides the API base (default https://api.codetime.dev). An HTTPS_PROXY / HTTP_PROXY env var is honored automatically.

Installing as a dev extension

The published flow downloads a prebuilt codetime-ls from GitHub releases. To run from source:

1. Build and expose the language server on your PATH (the extension prefers a codetime-ls found there before downloading one):

   cargo install --path codetime-ls
   # or: cargo build -p codetime-ls --release && cp target/release/codetime-ls ~/.local/bin/

2. In Zed, open the command palette → zed: install dev extension and select this repository's root. Zed compiles src/lib.rs to WASM and loads it.

3. Add your token (see above) and start editing. Watch the language server log (command palette → dev: open language server logs → CodeTime) to confirm events are sent.

Building

cargo build -p codetime-ls                          # native language server
rustup target add wasm32-wasip1                      # once
cargo build -p codetime-zed --target wasm32-wasip1   # the extension itself
