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.

The default branch of ZLS targets 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, payload capture type resolution, custom packages, and others. Support for comptime and semantic analysis is Work-in-Progress.

The majority of LSP features are supported:

• Completions
• Hover
• Diagnostics and opt-in build-on-save
• Go to definition/declaration
• Workspace symbols and document symbols
• Find references and rename symbol
• Formatting based on zig fmt
• Semantic tokens highlighting
• Inlay hints
• Code actions

We'd like to take a second to thank all our awesome contributors and donators/backers/sponsors; if you have time or money to spare, consider partaking in either of these options - they help keep ZLS awesome for everyone!
