Position and Range

Defines positions and ranges within a text document. Positions are zero-based and determine a point in a document by line and character offset. Ranges define a portion of text between two positions.

{ Position, Range } = require('vscode-languageserver-types');
let startPosition = Position.create(1, 5);
let endPosition = Position.create(1, 10);
let range = Range.create(startPosition, endPosition);

Text Edits

Allows for the creation of text edits, which are used to represent changes to a text document. These can be used to manipulate text by inserting, replacing, or deleting text in a document.

{ TextEdit } = require('vscode-languageserver-types');
let edit = TextEdit.replace(Range.create(Position.create(0, 0), Position.create(0, 10)), 'new text');

Diagnostics

Supports diagnostics, which are problems found in the code such as syntax errors or warnings. Diagnostics are associated with a range in the document and can have severities like Error, Warning, etc.

{ Diagnostic, Range, DiagnosticSeverity } = require('vscode-languageserver-types');
let diagnostic = Diagnostic.create(Range.create(Position.create(1, 0), Position.create(1, 1)), 'Syntax error', DiagnosticSeverity.Error, undefined, 'my-linter');
