filesystem

Documentation

Overview

Package filesystem implements a virtual filesystem which reflects the needs of both the language server and the HCL parser.

- creates in-memory files based on data received from the language client - allows updating in-memory files via diffs received from the language client - maintains file metadata (e.g. version, or whether it's open by the client)
