Features

1. YAML validation:

• Detects whether the entire file is valid yaml

2. Validation:

• Detects errors such as:
• Node is not found
• Node has an invalid key node type
• Node has an invalid type
• Node is not a valid child node
• Detects warnings such as:
• Node is an additional property of parent

3. Auto completion:

• Auto completes on all commands
• Scalar nodes autocomplete to schema's defaults if they exist

4. Hover support:

• Hovering over a node shows description *if available*

5. Document outlining:

• Shows a complete document outline of all nodes in the document

6. Go to definition for Templates

• Referenced templates can be resolved to a local file (if it exists)

Developer Support

This repo consists of 2 separate projects/packages: 1. * azure-pipelines-language-service - language service implementation for azure-pipelines 2. * azure-pipelines-language-server - language server implementation that dependes on azure-pipelines-language-service

In order to tighten the dev loop you can utilize npm link that will sync changes to service package without re-installing.

1. First, install dependencies in the language service and start watching for changes:

• cd language-service
• npm install
• npm run watch

2. Next, link the language service to the language server and start watching for changes:

• cd ../language-server
• npm install
• npm link ../language-service
• npm run watch

3. Now, any changes you make in the service will automatically be reflected in the server

Connecting to the language server via stdio

There's an option to connect to the language server via stdio to help with intergrating the language server into different clients.
