ELS - the Ember Language Server
summary
ELS implements an Ember language server that provides autocomplete and go-to-definition by parsing templates with @glimmer/syntax and using the vs code language server package for JSON‑RPC plumbing. It finds project roots with find-up and scans components via glob to suggest component names and template targets; it powers link-to resolution and i18n key navigation. It ships as extensions for VS Code and Atom and works well for many cases, but the Glimmer parser fails on incomplete/typing templates so editor robustness is still incomplete.
