Using lookbehind patterns in regex fails for python.
Repro code
open System.Text.RegularExpressions
let positiveLookbehind = """(?<=A).*"""
Regex(positiveLookbehind)
let negativeLookbehind = """(?<!A).*"""
Regex(negativeLookbehind)
Transpile to python and run.
Expected and actual results
Regex should be created, but fails with:
Traceback (most recent call last):
File "C:\Users\HLWei\Downloads\FableTesting\output\abc_.py", line 5, in <module>
create(positive_lookbehind)
...
re.error: missing >, unterminated name at position 4
This is caused by the following code in Fable reg_exp.py:
Which was probably originally added because of the different Regex syntax for grouping constructs.
