Previously, we would simulate disk-based diagnostics finishing after saving a buffer. However, the language server may produce diagnostics right after emitting the event, causing the diagnostics status bar item to not reflect the latest state of the buffer. With this change, we will instead simulate disk-based diagnostics finishing after 1s after saving the buffer (only for language servers that don't have the concept of disk-based diagnostics, such as TypeScript). This ensures we always reflect the latest state and doesn't cause the UI to flicker as a result of the LSP sending us diagnostics after every input.
Zed
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
LiveKitserver and theforemanprocess supervisor:brew install livekit brew install foreman -
Ensure the Zed.dev website is checked out in a sibling directory:
cd .. git clone https://github.com/zed-industries/zed.dev -
Set up a local
zeddatabase and seed it with some initial users: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](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 specifiederror for a crate you've created? If so, addpublish = falseunder[package]in your crate's Cargo.toml. - Is the error
failed to satisfy license requirementsfor 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 theacceptedarray inscript/licenses/zed-licenses.toml. - Is
cargo-aboutunable to find the license for a dependency? If so, add a clarification field at the end ofscript/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.
