About learn-yaml
Docs YAML Extension
Provides Docs YAML support via yaml-language-server.
Schemas supported to validate
There are two types of files that we run schema validation against:
1. For YAMLMime-based YAML files, we use the the YAMLMime to identify the schema to validate against according to our config. When schema files get updated, the extension will automatically pick up the latest version after a small latency (around 10 min). There is no need to reopen or reload the extension. When a new schema is added to this repository, we will to update the config and release a new version of the extension.
2. For TOC files, there is no YAMLMime at the beginning of the file, so we use the filename to identify the schema. The file name is case-sensitive; toc.yml and TOC.yml will both be be validated against the TOC schema, but toc.yaml and other variations will not.
Features
• The code intellisense is more intelligent now; the extension can provide the intellisense according to the schema structure, not just text mapping. To invoke intellisense, hit ctrl + space to view the list of schema options. • The extension can generate an input template for object (including required properties and optional properties with default value). • You can type a - and hit ctrl + space to trigger the intellisense for generating a new array item.
1. YAML validation
• Apply schema validation according to the YAMLMime • Detects errors such as: • Invalid property value type • Out of enum scope • Required property is missing • Unexpected property
2. Auto completion
• Generate input template for whole YAML file
For now, VS Code doesn't support auto-completion on a comment, so don't type # to get intellisense, just type YamlMime or YAMLMime type.
• Generate input template for an object (_if provided by schema_)
Including required properties and optional properties with default value
• Support properties intellisense (_if provided by schema_) • Enumerated property value recommendation (_if provided by schema_)
Intellisense is automatically triggered by what you have typed, but you can also hit _Ctrl + Space_ to get what you can type.
3. Hover support
• Hovering over a property shows description (_if provided by schema_)
Extra knowledge
YAMLMime
A YAML syntax to identify the mime type of this YAML document, which will decide the applied schema type, such as:
• YAMLMime should be the first line • There are should be a space between triple # and case-sensitive YamlMime • There are should not be extra space between YamlMime, Mime-type and :
