CUE LSP

Language Server implementation for CUE, with built-in support for Dagger.

Install

CUE LSP can be used in one of two ways:

• As a standalone binary cuelsp: go install github.com/dagger/cuelsp/cmd/cuelsp@latest
• As a subcommand of the Dagger CLI: dagger cuelsp. This requires dagger v0.2.27 or later.

Development & CI

We use Dagger to lint, test and build CUELSP. Using Dagger, commands running in the CI behave the same as on your local system 🚀

Action	Command
Run linter	dagger do lint
Run test	dagger do test
Build binary	dagger do build

If you are on Mac M1, you should build binary using go build -o cuelsp because Buildkit does not support darwin/arm64 platform, yet.

Release

CUELSP is versioned through tagged release.

There is a complete release workflow to produce CUELSP binaries for multiple platforms.

To publish a new release, we just create a new tag.

# Tag current commit
git tag vX.X.X

# Push tag to repository
git push origin vX.X.X
