# Language Server
|
|
|
|
The Enso Language Server is responsible for providing language services to the
|
|
Enso IDE (and other clients). This mainly involves speaking the Enso protocol
|
|
and orchestrating the runtime in response to this. It is responsible for:
|
|
|
|
- **Introspection Services:** Giving clients the ability to observe information
|
|
about their running code including values, types, profiling information, and
|
|
debugging.
|
|
- **Code Execution:** The ability for clients to execute arbitrary Enso code in
|
|
arbitrary scopes. This can be used in conjunction with the above to provide a
|
|
REPL with an integrated debugger.
|
|
- **Code Completion:** Sophisticated completion functionality that refines
|
|
suggestions intelligently based on context.
|
|
- **Node Management:** Tracking and providing the language server's internal
|
|
node representation of the Enso program.
|
|
- **Code Analysis:** Analysis functionality for Enso code (e.g. find usages,
|
|
jump-to-definition, and so on).
|
|
- **Refactoring:** Refactoring functionality for Enso code (e.g. rename, move,
|
|
extract, and so on).
|
|
- **Type Interactions:** Features for type-driven-development that allow users
|
|
to interact with the types of their programs.
|
|
|
|
This folder contains all documentation pertaining to the Language Server, which
|
|
is broken up as follows:
|
|
|

|
|
and types
