github.com/cue-lang/cuelang.org - the home of cuelang.org

This repo is the home of cuelang.org. The site is built using Hugo and is based on the docsy theme.

The CUE Language Specification is generated from source files in the cuelang.org/go module.

The site is deployed and hosted via Netlify.

Issue tracking

To raise an issue about a specific page or piece of content, scroll to the bottom of the published page and use the "Report an Issue" link in the site footer. This link will save you time by prepopulating the issue with information that you'll need to find and fill in if you raise the issue manually.

To raise an issue manually, please open it in the main CUE issue tracker, giving the issue's title a "cuelang.org: " prefix.

Requirements for local development

• NodeJS v20.x
• Go >= go1.23 (not needed for only running hugo)
• Hugo == v0.128.2 ("extended" binary version)
• Docker CLI >= 19.03 (for docker buildx use, amongst other things)
  • Podman has been used successfully, instead of Docker, but its use is currently undocumented
• When adding or changing pages that interact with the CUE Central Registry (or making changes to "infra" bits like the preprocessor), your registry account must have been granted the test manager role, and you must have run cue login successfully.

Directory structure

• content: the unprocessed website content
• hugo: hugo-specific content, likely generated from the content directory by the preprocessor
• playground: the app code for the cue-playground (/play)
• functions: cloud functions
• internal: internal stuff that can be ignored
• cue.mod/go.mod/go.sum: can be ignored

Developing the site locally

To serve the site locally run:

./_scripts/build.bash             # one-off to ensure everything works
./_scripts/serve.bash [--update]  # update flag writes changes back into source files under content/

The site will be served at http://localhost:1313/.

Updating the version of CUE documented by the site

The site's CUE content is formatted, tested, and used to produce output by the latest version of CUE stored in site.cue.

See commit https://github.com/cue-lang/cuelang.org/commit/80c17ba707e239adfe7794ffcfc79f314ed51841 (and the commit that comes after, updating cache files) for an example of how to update this version.

The spec is handled by a different version of CUE, as tracked in cue-lang/cue#3013. It is generated against the required version of the cuelang.org/go module:

go generate ./...

To update the generated spec you need to update the site's required version of cuelang.org/go:

go get cuelang.org/go@latest

tip.cuelang.org

tip.cuelang.org currently redirects to cuelang.org, but it is intended that this site should:

• have the same template and content as cuelang.org, except that all pages will have their data formatted and output emitted by cuelang.org/go@master;
• be redeployed when any commit is added to to master on cue-lang/cuelang.org or cue-lang/cue.

This is not currently implemented, and is tracked in https://cuelang.org/issues/2538.
