Support incomplete parsing #5764
Conversation
|
This brings the project a step closer to having a single REPL implementation! There's still some deficiencies in the stdlib parser for parsing blocks for functions/classes though. |

Does this work? Then partially reverting #5743 to the original code will be better, including the upper comment.

That doesn't work, since _IncompleteInputError doesn't necessarily have that string in the error. I've removed the comment and changed this block to just match python 3.15's implementation at least.

looks good, thank you so much!
This PR adds support for incomplete parsing both in the native REPL and in the stdin REPL (in particular multiline input support is expanded for to allow more cases such as multiline strings). The implementation adds compatibility for cpython's
PY_CF_ALLOW_INCOMPLETE_INPUTcompile flag and adds a new exception type similar to python 3.14.
