# Zed
[![CI](https://github.com/zed-industries/zed/actions/workflows/ci.yml/badge.svg)](https://github.com/zed-industries/zed/actions/workflows/ci.yml)
Welcome to Zed, a lightning-fast, collaborative code editor that makes your dreams come true.
## Development tips
### Dependencies
* Install Xcode from https://apps.apple.com/us/app/xcode/id497799835?mt=12, and accept the license:
```
sudo xcodebuild -license
```
* Install homebrew, node and rustup-init (rustup, rust, cargo, etc.)
```
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install node rustup-init
rustup-init # follow the installation steps
```
* Install postgres and configure the database
```
brew install postgresql@15
brew services start postgresql@15
psql -c "CREATE ROLE postgres SUPERUSER LOGIN" postgres
psql -U postgres -c "CREATE DATABASE zed"
```
* Install the `LiveKit` server, the `PostgREST` API server, and the `foreman` process supervisor:
```
brew install livekit
brew install postgrest
brew install foreman
```
* Ensure the Zed.dev website is checked out in a sibling directory and install its dependencies:
```
cd ..
git clone https://github.com/zed-industries/zed.dev
cd zed.dev && npm install
npm install -g vercel
```
* Return to Zed project directory and Initialize submodules
```
cd zed
git submodule update --init --recursive
```
* Set up a local `zed` database and seed it with some initial users:
[Create a personal GitHub token](https://github.com/settings/tokens/new) to run `script/bootstrap` once successfully: the token needs to have an access to private repositories for the script to work (`repo` OAuth scope).
Then delete that token.
```
GITHUB_TOKEN=<$token> script/bootstrap
```
* Now try running zed with collaboration disabled:
```
cargo run
```
### Common errors
* `xcrun: error: unable to find utility "metal", not a developer tool or in PATH`
* You need to install Xcode and then run: `xcode-select --switch /Applications/Xcode.app/Contents/Developer`
* (see https://github.com/gfx-rs/gfx/issues/2309)
### Testing against locally-running servers
Start the web and collab servers:
```
foreman start
```
If you want to run Zed pointed at the local servers, you can run:
```
script/zed-with-local-servers
# or...
script/zed-with-local-servers --release
```
### Dump element JSON
If you trigger `cmd-alt-i`, Zed will copy a JSON representation of the current window contents to the clipboard. You can paste this in a tool like [DJSON](https://chrome.google.com/webstore/detail/djson-json-viewer-formatt/chaeijjekipecdajnijdldjjipaegdjc?hl=en) to navigate the state of on-screen elements in a structured way.
### Licensing
We use [`cargo-about`](https://github.com/EmbarkStudios/cargo-about) to automatically comply with open source licenses. If CI is failing, check the following:
- Is it showing a `no license specified` error for a crate you've created? If so, add `publish = false` under `[package]` in your crate's Cargo.toml.
- Is the error `failed to satisfy license requirements` for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the `accepted` array in `script/licenses/zed-licenses.toml`.
- Is `cargo-about` unable to find the license for a dependency? If so, add a clarification field at the end of `script/licenses/zed-licenses.toml`, as specified in the [cargo-about book](https://embarkstudios.github.io/cargo-about/cli/generate/config.html#crate-configuration).
### Wasm Plugins
Zed has a Wasm-based plugin runtime which it currently uses to embed plugins. To compile Zed, you'll need to have the `wasm32-wasi` toolchain installed on your system. To install this toolchain, run:
```bash
rustup target add wasm32-wasi
```
Plugins can be found in the `plugins` folder in the root. For more information about how plugins work, check the [Plugin Guide](./crates/plugin_runtime/README.md) in `crates/plugin_runtime/README.md`.
