YAML language support, including JSON Schema validation, for Visual Studio Code

YAML for Visual Studio Code

Features

• JSON Schema validation
• Quick Navigation (Ctrl + Shift + O)
• Document formatting
• Hover data descriptions (when provided by active schemas)

How to associate schemas

Schemas are handled exactly same way they are with JSON in Visual Studio Code and your schema file must still be written in JSON. This means you can:

• Declare in the current file by specify a $schema element.
• Map files by settings using the json.schemas settings key in User Settings, Workspace Settings, or even define your schema within Settings.
• Define in extensions using the jsonValidation contribution point.

Known Issues

• No support has been implemented for include references. (relevant code)
• Formatter strips comments and --- yaml marker. see issues/#9
• Formatter renames anchors/references in the style &ref12/*ref12

Acknowledgments

This extension would not have been possible without numerous open source projects. Please see ACKNOWLEDGMENTS.md.

vscode-yaml's Issues

unpublished from marketplace

Why was this extension unpublished from VS Marketplace?

Merging in multiple anchors results in validation error

When using anchors and merging multiple anchors into the same object Visual Studio Code complains about invlid document.

Document:

.numbers: &numbers
  one: "1"
  two: "2"

.countries: &countries
  us: "United States"
  uk: "United Kingdom"

instance1:
  <<: *numbers
  <<: *countries
  something: "else"

Expected result: The document is valid

Actual result: Error in validating document

JS-YAML: duplicate key at line 10, column 3
JS-YAML: duplicate key at line 11, column 3

Include support for JSON Schema in YAML format

JSON is already unnecessarily verbose, and JSON Schema definitions don't make it any better. I would like to see support for JSON Schema validation against definitions in YAML format instead of JSON, so we can forget about the format entirely.

unknown tag <tag:yaml.org,2002:str>

"yes as a boolean": yes
"yes as a string": "yes"
"yes as a string with tag": !!str yes

The third line causes the error in the title of the issue. Is there currently no support for the recommended schemas? If so, there should be at least some documentation on how to add this support locally.

Option to disable validation

I have some Symfony config files that currently do not fit into valid yaml, meaning some properties start with % and no ' or " before that.
Is there a way to disable the validation for valid yaml but keep the highlighting.

the operation of format while remove comment

when format the file, it while remove comment also, how to change this?

Auto-completion when using JSON Schema

I noticed auto-completion doesn't work when using a JSON schema, although the validation works fine. Is expected to be working? If it is, then would this be a bug in the vscode-yaml extension or in VS Code?Whatever the case, congrats for this excellent extension - it saved me and my team countless hours.

Auto-completion by context

Would it be possible to have auto-completion based on the YAML context. For example, if I'm typing a key in an associative array, it would complete based on other keys, if I'm typing a value, other values, etc?

The server crashes

VSCode said the server crashed 5 times in 3 minutes. It won't be started again.

feature request: jinja support?

Thanks for this plugin, very useful.

Not sure how this might be done, but I'll ask anyway 😄 ... is it possible to somehow enable jinja2 support for validation? I guess this might be a wider issue for vscode too, not only for this plugin. But I have a yaml file with some jinja2 tags that looks like this:

The errors/warnings I get are:

It'd be great if this could look a bit nicer somehow.

FYI, these yaml files are from openstack rally

Thanks!

Possible to disable linting onChange?

I’d prefer the linting to occur only when I save, or trigger it manually. I apologize if this is obvious; I’m new to VS Code and couldn’t figure this out after ~15 minutes of searching.

clientSnippetSupport field in yamlServerMain.ts is unused

The clientSnippetSupport field is assigned but never actually used. Should it be removed instead?

vscode-yaml/server/src/yamlServerMain.ts

Lines 55 to 85 in 7b6097a

	let clientSnippetSupport = false;
	let clientDynamicRegisterSupport = false;
	// After the server has started the client sends an initilize request. The server receives
	// in the passed params the rootPath of the workspace plus the client capabilities.
	let workspaceRoot: URI;
	connection.onInitialize((params: InitializeParams): InitializeResult => {
	workspaceRoot = URI.parse(params.rootPath);
	function hasClientCapability(...keys: string[]) {
	let c = params.capabilities;
	for (let i = 0; c && i < keys.length; i++) {
	c = c[keys[i]];
	}
	return !!c;
	}
	clientSnippetSupport = hasClientCapability('textDocument', 'completion', 'completionItem', 'snippetSupport');
	clientDynamicRegisterSupport = hasClientCapability('workspace', 'symbol', 'dynamicRegistration');
	return {
	capabilities: {
	// Tell the client that the server works in FULL text document sync mode
	textDocumentSync: documents.syncKind,
	// Disabled because too JSON centric
	// completionProvider: { resolveProvider: false },
	hoverProvider: true,
	documentSymbolProvider: true,
	documentFormattingProvider: false
	}
	};
	});

YAML syntax errors crash vscode

Running latest vscode and your plugin

When i make some syntax mistakes in yaml files, and vscode correctly tries to highlight those the whole vscode will eventually crash

• The error is highlighted, along with every line in the file (seems wrong?)
• Not sure where to look for logs, but eventually the window crashes

JS-YAML: unknown tag <!Join>

Hi,

Unfortunately I have some problems to validate yaml documents for AWS CloudFormation.
I have following line in my Template:
TemplateURL: !Join ["/", [ !FindInMap [CFNBucket, !Ref "AWS::Region", !Ref "Environment" ], "cfn-generic/s3_single.yaml"]]

Starting with !Join I get following error:
JS-YAML: unknown tag <!Join> at line 37, column 20

Is there a solution to workaround with this, so that I can validate my templates. E.g. CustomTags that are ignored.

Comments removed when formatting

I can't figure out how to stop it but this plugin removes all comments # Foo from my yaml files.

yaml server crashing

Running vscode on osx. Tried re-installing the plugin but no luck.
