Installation

Deputy can be installed as an extension from:

The Visual Studio Marketplace (VSCode)
The Open VSX Registry (Cursor, Windsurf, ...)
The Zed Extensions registry ^[1]

^[1] Additional extensions for TOML/Go language support may need to be installed first for corresponding Deputy features to be recognized and work in Zed.

Extensions can also be built and installed from source:

Manual Installation - VSCode

Install Bun
Clone this repository, and navigate to the editors/vscode directory
Build and install the extension by running these three commands, in order:
```
bun install
bun pm trust --all
bun run extension-install
```

Manual Installation - Zed

Install Rust
Clone this repository, and navigate to the root directory
Install the Zed extension at editors/zed as a dev extension

Features

Autocomplete for names, versions, and features
Hover for information - includes description, links to documentation & more
Diagnostics:
- A newer version is available
- The specified tool / package / version does not exist
Quick actions on diagnostics - update to newest version

Command Line

Deputy can also run diagnostics over a workspace without starting an editor:

deputy analyze

By default, this checks the current directory for supported manifests and prints diagnostics with source snippets. Error diagnostics will cause the command to exit with a non-zero status code, making it suitable for CI.

Why "Deputy"?

This project was previously called "Tooling Language Server", but I felt it was a bit too generic and verbose.

Deputy is mostly just a fun wordplay on "Dependency" and "Utility", but you can also interpret it using the literal meaning of the word.
Deputy helps you (the sheriff of dependencies) stay informed, and keep your versions up to date. 🤠
