* allow omitting stmts using `finally` as post expr blocks; make it consistent ↵ringabout2023-02-141-1/+1
| | | | | with `else`, `except` etc. (#21361) allow omitting stmts using `finally` as post expr blocks
* Implemented basic macro expand functionality (#20579)Ivan Yonchovski2023-01-271-5/+65
| | | | | | | | | | | | | | | | | | * 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
* fix in msg `doAssert()` to update grammar.txt (#21179)rockcavera2022-12-271-1/+1

* fix issue #20922 by handling missing expr in `exprList` for `tkOf` (#20930)Vindaar2022-12-081-5/+23
| | | | | | | | | | | | | | | | | | * fix issue #20922 by handling missing expr in `exprList` for `tkOf` * fix line numbers in test case * rewrite exprList requiring expr, add optionalExprList for except As suggested by @metagn. * update test case to reflect new code * update grammar.txt * update line numbers in test case taking into account nimout Given the number of errors that are produced it seems easier to do it this way instead of using `tt.Error`.
