Overview

Package lsppos provides utilities for working with LSP positions.

See https://microsoft.github.io/language-server-protocol/specification#textDocuments for a description of LSP positions. Notably:

• Positions are specified by a 0-based line count and 0-based utf-16 character offset.
• Positions are line-ending agnostic: there is no way to specify \r|\n or \n|. Instead the former maps to the end of the current line, and the latter to the start of the next line.
