Create a diagnostics collection.
The name of the collection.
A new diagnostic collection.
Get all diagnostics for a given resource. Note that this includes diagnostics from all extensions but not yet from the task framework.
A resource
An array of diagnostics objects or an empty array.
Get all diagnostics. Note that this includes diagnostics from all extensions but not yet from the task framework.
An array of uri-diagnostics tuples or an empty array.
Return the identifiers of all known languages.
Promise resolving to an array of identifier strings.
Compute the match between a document selector and a document. Values greater than zero mean the selector matches the document.
A match is computed according to these rules:
DocumentSelector is an array, compute the match for each contained DocumentFilter or language identifier and take the maximum value.language-part of a DocumentFilter, so "fooLang" is like { language: "fooLang" }.DocumentFilter will be matched against the document by comparing its parts with the document. The following rules apply:DocumentFilter is empty ({}) the result is 0scheme, language, or pattern are defined but one doesn’t match, the result is 0* gives a score of 5, matching via equality or via a glob-pattern gives a score of 10Samples:
// default document from disk (file-scheme)
doc.uri; //'file:///my/file.js'
doc.languageId; // 'javascript'
match('javascript', doc); // 10;
match({language: 'javascript'}, doc); // 10;
match({language: 'javascript', scheme: 'file'}, doc); // 10;
match('*', doc); // 5
match('fooLang', doc); // 0
match(['fooLang', '*'], doc); // 5
// virtual document, e.g. from git-index
doc.uri; // 'git:/my/file.js'
doc.languageId; // 'javascript'
match('javascript', doc); // 10;
match({language: 'javascript', scheme: 'git'}, doc); // 10;
match('*', doc); // 5A document selector.
A text document.
A number >0 when the selector matches and 0 when the selector does not match.
Register a code action provider.

Register a completion provider.
Multiple providers can be registered for a language. In that case providers are sorted by their score and groups of equal score are sequentially asked for completion items. The process stops when one or many providers of a group return a result. A failing provider (rejected promise or exception) will not fail the whole operation.

Register a formatting provider for a document range.
Note: A document range provider is also a document formatter which means there is no need to register a document formatter when also registering a range provider.
Multiple providers can be registered for a language. In that case providers are sorted by their score and the best-matching provider is used. Failure of the selected provider will cause a failure of the whole operation.
