ZLS is a non-official implementation of the Language Server Protocol for Zig in Zig. It provides developers with IDE features in their editor.

The complete installation guide is available on the Zigtools website. It covers editor setup, prebuilt binaries and additional documentation.

Building ZLS requires a build of Zig master.

git clone https://github.com/zigtools/zls
cd zls
zig build -Doptimize=ReleaseSafe

When upgrading Zig, make sure to update ZLS too keep them in sync.

ZLS supports most language features, including simple type function support, using namespace, payload capture type resolution, custom packages, cImport and others. Support for comptime and semantic analysis is Work-in-Progress.

The following LSP features are supported:

• Completions
• Hover
• Goto definition/declaration
• Document symbols
• Find references
• Rename symbol
• Formatting using zig fmt
• Semantic token highlighting
• Inlay hints
• Code actions
• Selection ranges
• Folding regions
