* Implemented basic macro expand functionality (#20579)Ivan Yonchovski2023-01-271-1/+1
| | | | | | | | | | | | | | | | | | * Implemented level based macro expand functionality - it can handle single macro call or expand whole function/proc/etc and it - In addition, I have altered the parser to provide the endInfo for the node. The usefulness of the `endInfo` is not limited to the `expandMacro` functionality but also it is useful for `ideOutline` functionality and I have altered the ideOutline functionality to use `endInfo`. Note `endInfo` most of the time is lost during the AST transformation thus in `nimsuggest.nim` I am using freshly parsed tree to get the location information. * Make sure we stop expanding correctly * Test CI * Fix tv3_outline.nim
