Description

Hi there,

I'm using a CustomContextProvider that sends a selected code snippet to a code analysis tool to enrich the context with its report.

To do this, I use an implementation of getContextItens and access information about the selected code in extras.fullInput and extras.selectedCode.

This works fine in Chat mode, but in Edit mode the expected information is not sent to my implementation. The logs below show the difference in behavior in the two cases.

The interface in each mode is a bit different, so it makes sense that they don't behave the same way at the moment. But I'd like my CustomContextProvider to work the same way in both cases anyway, and I couldn't find anything in the reference that says this is an expected limitation or that offers an alternative implementation for Edit mode.

Thanks for your support guys.

To reproduce

1. Replace your config.ts with my example in Relevant environment information of this post
2. Type ">Developer: Toggle Developer Tools" in the Visual Studio Code search bar to open the Developer Tools window
3. In the Developer Tools window, select the console panel and in the filter bar type "Extension Host"
4. In Visual Studio Code select a piece of code, in my example I selected the entire modfyConfig function from config.ts
5. Open Continue in chat mode (ctrl+L), type "@" and "custom-context", send the request
6. Open Continue in edit mode (ctrl+I), type "@" and "custom-context", send the request

Log output

export function modifyConfig(config: Config): Config {

  return config;
}
