To test the functionality, I asked AI to show me the result of the `operator70395` variable:

1. Init protocol connection
```json
{"jsonrpc":"2.0","id":0,"method":"session/initProtocolConnection","params":{"clientId":"d8e948fd-6418-43c8-9f02-54827f09e10a"}}
```

2. Create execution context
```json
{"jsonrpc":"2.0","id":0,"method":"session/initProtocolConnection","params":{"clientId":"d8e948fd-6418-43c8-9f02-54827f09e10a"}}
```

3. Push the main method
```json
{"jsonrpc":"2.0","id":0,"method":"executionContext/push","params":{"contextId":"730a66ef-4222-46f8-8a03-d766946ab2bd","stackItem":{"methodPointer":{"module":"local.New_Project_1.Main","definedOnType":"local.New_Project_1.Main","name":"main"},"positionalArgumentsExpressions":[],"type":"ExplicitCall"}}}
```

4. Ask AI for the variable contents
```json
{"jsonrpc":"2.0","id":1,"method":"ai/completion_v2","params":{"contextId":"730a66ef-4222-46f8-8a03-d766946ab2bd","expressionId":"f09a4372-3231-4f2e-99f4-84aa751f9b60","prompt":"There is 'operator70395' variable defined in the program. What is the result of the variable 'operator70395'?"}}
```

I got the following responses:
```json
{"jsonrpc":"2.0","method":"ai/completionProgress","params":{"code":"Visualization.AI.print(operator70395)","reason":"To provide the result of 'operator70395', I need to know its current value.","visualizationId":"edfb00a3-6ce5-41e1-bb8f-ab191809114e"}}
```
```json
{"jsonrpc":"2.0","id":1,"result":{"Success":{"fn":"def get_operator70395_result():\n    return operator70395","fnCall":"get_operator70395_result()"}}}

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:

The protocol messages are broken up into documents as follows:
