None! yaml-language-server is bundled with this package.
Features
Code completion (via autocomplete-plus) for YAML properties and values based on the document’s schema. Schemas for some common types are included; others can be configured.
Validation (via linter and linter-ui-default).
Document symbol resolution (via symbols-view) for properties in the document.
Hover (via pulsar-hover) for rich tooltip content based on descriptions in the document’s schema.
Format-as-you-type support (via pulsar-code-format). (Whole-document formatting and selected-range formatting are not yet supported by the underlying language server.)
Outline support (via pulsar-outline-view) for a hierarchical representation of the YAML document.
Configuration
Node path
Tip
Soon pulsar-ide-yaml will be able to use Pulsar’s built-in version of Node. For now, though, the built-in version is too old; you’ll have to tell the language server the path to your local version of Node.
The version of Node inherited from your shell environment will usually suffice; if Pulsar fails to find it, you may specify the absolute path to your version of node in the “Path To Node Binary” configuration field.
Schemas
Builtin schemas
Some common schemas are included out of the box:
docker-compose.yml
GitHub Actions workflow
Explicit schemas
You can opt into a certain schema with a modeline comment…
# yaml-language-server: $schema=<schemaPath>
…where <schemaPath> can be a URL, a relative path, or an absolute path.
Custom schemas
Other JSON schemas can be added — not through the settings UI, but via your config.cson. For each new JSON schema you want to add, create a new object property like so:
The key is a path to a schema (whether local on disk or a URL); the value is either a single glob (described relative to the project root) or an array of multiple such globs.
