Query certain editor ranges for inlays with a delay (#2891)
Part of
https://linear.app/zed-industries/issue/Z-2750/investigate-performance-of-collaborating-on-large-files-with-inlay
Fixes
https://linear.app/zed-industries/issue/Z-2824/inlay-hints-affect-code-layout-in-multibuffer

We query hints for visible part of the screen, and two parts above and
below the visible range, of the same range (if applicable, we can be on
the edge of the document).

When rapidly typing, we do not care about the invisible range updates,
yet still query a lot of them + rust-analyzer sends /refresh hint
requests shortly after every modification too, forcing us to re-query.

Instead querying both visible and invisible ranges altogether, wait for
visible range query first and wait add a `400ms` delay afterwards before
querying the invisible ranges.
This allows any /refresh requests or rapid typing to avoid 2 extra
requests, cancelling them before they start.
Visible part of the screen is still queried after every change, without
any debouncing.

Release Notes:

- Delay certain inlay hint requests to reduce general LSP server load

Zed

CI

Welcome to Zed, a lightning-fast, collaborative code editor that makes your dreams come true.

Development tips

Dependencies

  • Install Postgres.app and start it.

  • Install the LiveKit server and the foreman process supervisor:

    brew install livekit
    brew install foreman
    
  • Ensure the Zed.dev website is checked out in a sibling directory and install it's 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 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
    

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 to navigate the state of on-screen elements in a structured way.

Licensing

We use 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.

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:

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 in crates/plugin_runtime/README.md.
