VB6 string concatenation with TextBox.Text$ not working #1

Closed maxiz closed 7 years ago

maxiz commented 7 years ago

I'm using the VB6.g4 grammar file. It seems to throw an exception on statements like filepath$ = filename.Text$ & "\abc" & filepath$ & ".txt" and If Func1(filname.Text$ & "\Logfiles", True) = True Then. Removing the $ from filename.Text$ would solve the issue but I would've expected the grammar to successfully match the statement. So I'm trying to understand why $ is throwing off the parser.

Any help in identifying the problem is much appreciated!

Yes, type hints should be parsed by the grammar. Let's see, if we can identify the problem.

To reproduce the problem, I added a unit test TypeHintTest.java that parses TypeHint.cls containing the expressions given by you. The test passes. Also the parse tree TypeHint.cls.tree seems to be correct.

Could you please provide a modified version of TypeHint.cls, which reproduces the problem? Thanks!

I tried to reproduce my issue by modifying the TypeHint.cls file, but the test passed fine. So I'm closing this issue. Thank you for helping :)
