Update local development workflow to not involve zed.dev (#4103)

Max Brunsfeld created

When testing Zed locally, it's rarely necessary to log in the real with,
via Zed.dev and GitHub. We usually use `zed-local`. Since zed.dev is not
going to be open source (at least right away), this PR removes it from
our local development workflow.

* Remove zed.dev from the Procfile
* Change the `seed` script to not create an admin user for your
signed-in github user
* Instead have both `zed-local` and the `seed` script read from an
`.admins.json` file, which the user can create in order to customize who
they sign in as when running `zed-local`.
* Update all of the docs for building and developing zed.

 # Building Zed
 
-🚧 TODO:
+## Dependencies
 
-- [ ] Remove ZI-specific things
-- [ ] Rework any steps that currently require a ZI-specific account
+- Install [Rust](https://www.rust-lang.org/tools/install)
+- Install [Xcode](https://apps.apple.com/us/app/xcode/id497799835?mt=12) from the macOS App Store
 
-How to build Zed from source for the first time.
+- Install [Xcode command line tools](https://developer.apple.com/xcode/resources/)
 
-### Prerequisites
+    ```bash
+    xcode-select --install
+    ```
 
-🚧 TODO 🚧 Update for open source
+- Ensure that the Xcode command line tools are using your newly installed copy of Xcode:
 
-- Be added to the GitHub organization
-- Be added to the Vercel team
-- Create a [Personal Access Token](https://github.com/settings/personal-access-tokens/new) on Github
-  - 🚧 TODO 🚧 What permissions are required?
-  - 🚧 TODO 🚧 What changes when repo isn't private?
-  - Go to https://github.com/settings/tokens and Generate new token
-  - GitHub currently provides two kinds of tokens:
-    - Classic Tokens, where only `repo` (Full control of private repositories) OAuth scope has to be selected
-      Unfortunately, unselecting `repo` scope and selecting every its inner scope instead does not allow the token users to read from private repositories
-    - (not applicable) Fine-grained Tokens, at the moment of writing, did not allow any kind of access of non-owned private repos
-  - Keep the token in the browser tab/editor for the next two steps
+    ```
+    sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer.
+    ```
 
-### Dependencies
+* Install the Rust wasm toolchain:
 
-- Install [Rust](https://www.rust-lang.org/tools/install)
+    ```bash
+    rustup target add wasm32-wasi
+    ```
 
-- Install the [GitHub CLI](https://cli.github.com/), [Livekit](https://formulae.brew.sh/formula/livekit) & [Foreman](https://formulae.brew.sh/formula/foreman)
+## Backend Dependencies
 
-```bash
-brew install gh
-brew install livekit
-brew install foreman
-```
+If you are developing collaborative features of Zed, you'll need to install the dependencies of zed's `collab` server:
 
-- Install [Xcode](https://apps.apple.com/us/app/xcode/id497799835?mt=12) from the macOS App Store
+- Install [Postgres](https://postgresapp.com)
+- Install [Livekit](https://formulae.brew.sh/formula/livekit) and [Foreman](https://formulae.brew.sh/formula/foreman)
 
-- Install [Xcode command line tools](https://developer.apple.com/xcode/resources/)
+    ```bash
+    brew install livekit foreman
+    ```
 
-```bash
-xcode-select --install
-```
-
-- If `xcode-select --print-path prints /Library/Developer/CommandLineTools…` run `sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer.`
+## Building Zed from Source
 
-* Install [Postgres](https://postgresapp.com)
+Once you have the dependencies installed, you can build Zed using [Cargo](https://doc.rust-lang.org/cargo/).
 
-* Install the wasm toolchain
+For a debug build:
 
-```bash
-rustup target add wasm32-wasi
 ```
-
-### Building Zed from Source
-
-1. Clone the `zed` repo
-
-```bash
-gh repo clone zed-industries/zed
+cargo run
 ```
 
-1. (Optional but recommended) Add your GITHUB_TOKEN to your `.zshrc` or `.bashrc` like this: `export GITHUB_TOKEN=yourGithubAPIToken`
-1. (🚧 TODO 🚧 - Will this be relevant for open source?) Ensure the Zed.dev website is checked out in a sibling directory and install its dependencies:
+For a release build:
 
-```bash
-cd ..
-git clone https://github.com/zed-industries/zed.dev
-cd zed.dev && npm install
-pnpm install -g vercel
+```
+cargo run --release
 ```
 
-1. (🚧 TODO 🚧 - Will this be relevant for open source?) Link your zed.dev project to Vercel
-
-- `vercel link`
-- Select the `zed-industries` team. If you don't have this get someone on the team to add you to it.
-- Select the `zed.dev` project
-
-1. (🚧 TODO 🚧 - Will this be relevant for open source?) Run `vercel pull` to pull down the environment variables and project info from Vercel
-1. Open Postgres.app
-1. From `./path/to/zed/` run `GITHUB_TOKEN={yourGithubAPIToken} script/bootstrap`
-
-- You don't need to include the GITHUB_TOKEN if you exported it above.
-- Consider removing the token (if it's fine for you to recreate such tokens during occasional migrations) or store this token somewhere safe (like your Zed 1Password vault).
+And to run the tests:
 
-1. To run the Zed app:
-   - If you are working on zed:
-     - `cargo run`
-   - If you are just using the latest version, but not working on zed:
-     - `cargo run --release`
-   - If you need to run the collaboration server locally:
-     - `script/zed-local`
+```
+cargo test --workspace
+```
 
 ## Troubleshooting
 
-**`error: failed to run custom build command for gpui v0.1.0 (/Users/path/to/zed)`**

 # Local Collaboration
 
-## Setting up the local collaboration server
+First, make sure you've installed Zed's [backend dependencies](/developing_zed__building_zed.html#backend-dependencies).
 
-### Setting up for the first time?
+## Database setup
 
-1. Make sure you have livekit installed (`brew install livekit`)
-1. Install [Postgres](https://postgresapp.com) and run it.
-1. Then, from the root of the repo, run `script/bootstrap`.
+Before you can run the `collab` server locally, you'll need to set up a `zed` Postgres database.
 
-### Have a db that is out of date? / Need to migrate?
+```
+script/bootstrap
+```
 
-1. Make sure you have livekit installed (`brew install livekit`)
-1. Try `cd crates/collab && cargo run -- migrate` from the root of the repo.
-1. Run `script/seed-db`
+This script will set up the `zed` Postgres database, and populate it with some users. It requires internet access, because it fetches some users from the GitHub API.
 
-## Testing collab locally
+The script will create several *admin* users, who you'll sign in as by default when developing locally. The GitHub logins for these default admin users are specified in this file:
 
-1. Run `foreman start` from the root of the repo.
-1. In another terminal run `script/zed-local`.
-1. Two copies of Zed will open. Add yourself as a contact in the one that is not you.
-1. Start a collaboration session as normal with any open project.
+```
+cat crates/collab/.admins.default.json
+```
+
+To use a different set of admin users, you can create a file called `.admins.json` in the same directory:
+
+```
+cat > crates/collab/.admins.json <<JSON
+[
+  "your-github-login",
+  "another-github-login"
+]
+JSON
+```
+
+## Testing collaborative features locally
+
+In one terminal, run Zed's collaboration server and the `livekit` dev server:
+
+```
+foreman start
+```
+
+In a second terminal, run two or more instances of Zed.
+
+```
+script/zed-local -2
+```
+
+This script starts one to four instances of Zed, depending on the `-2`, `-3` or `-4` flags. Each instance will be connected to the local `collab` server, signed in as a different user from `.admins.json` or `.admins.default.json`.
