isContextRequiredForChatQuery

• counts from a database if the query is similar to messages that require context. Has a low threshold of 0.02, so need to be really sure no context is needed.

There are predefined recipes you can click on

export const recipesList = {
    'explain-code-detailed': 'Explain selected code (detailed)',
    'explain-code-high-level': 'Explain selected code (high level)',
    'generate-unit-test': 'Generate a unit test',
    'generate-docstring': 'Generate a docstring',
    'improve-variable-names': 'Improve variable names',
    'translate-to-language': 'Translate to different language',
    'git-history': 'Summarize recent code changes',
}

Each Recipe’s main method is getInteraction()

ChatQuestion is also a Recipe - that’s the freeform one

• getInteraction() = human prompt, empty asst, and .getContextMessages()
• getContextMessages():

  • If isContextRequiredForChatQuery, then append codebaseContext.getContextMessages()

    • contextType defaults to embeddings (in VSC config). For this…

      • (context is split into multiple human messages followed by asst responding “Ok.”, truncated by token limit)

      • embeddings search (via Sourcegraph servers)

        • up to 8 code results and 2 text results

      • Snippets are included with:

        const CODE_CONTEXT_TEMPLATE = `Use following code snippet from file \\`{filePath}\\`:
        \\`\\`\\`{language}
        {text}
        \\`\\`\\``
        

      • There’s also slightly different handling of markdown

  • If code or editor context required (determined from regex for “current file” etc.), then append getEditorContext()

    • include visible content

    const CURRENT_EDITOR_CODE_TEMPLATE = `I have the \\`{filePath}\\` file opened in my editor. You are able to answer questions about \\`{filePath}\\`. The following code snippet is from the currently open file in my editor \\`{filePath}\\`:
    \\`\\`\\`{language}
    {text}
    \\`\\`\\``
    

Another example: GenerateTest

• human:

  `Generate a unit test in ${languageName} for the following code:\\n\\`\\`\\`${extension}\\n${truncatedSelectedText}\\n\\`\\`\\`\\n${MARKDOWN_FORMAT_PROMPT}`
  

• asst:

  `Here is the generated unit test:\\n\\`\\`\\`${extension}\\n`
  

• getContextMessagesFromSelection: include similar snippets search for selection (codebase context), and include selection, using the standard codebase context stuff

Interaction(human, asst, context) = […context, human, asst]

Searches and sources are from Sourcegraph server, so it may be different from what’s local
