-- Modified to:
|
||
-- 1) Determine the Git root based on the currently opened file.
|
||
-- 2) If no file is open or not in Git repo, fallback to current working directory.
|
||
-- 3) Add support for configuring a list of default prompt blocks ("go-development", "typo3-development", "basic-prompt") that can override the initial prompt if provided.
|
||
-- 4) Add support for configuring a token limit.
