Feature/Bug: Disable cache for Parse Tree #264

Open lublak opened 4 months ago

lublak commented 4 months ago

I sometimes have the problem that the Prae Tree does not update. I have adjusted the rules but the parse tree does not update after "F5". Only a complete restart of vscode solves the problem. Is a cache to blame here? And would it be possible to simply have an option to deactivate it?

lublak commented 4 months ago

Another thing: apparently the parse tree is already updating itself. But not the rules behind it. So as soon as I change the input file, the tree updates. but based on the opened grammar file. If I change the grammar file, it does not update. Even if I then change the input file, it still adopts the state from before the change in the Grammar file.

Example, bevor change:

grafik grafik

Example, after change:

grafik grafik

Example, after restarting vscode:

grafik

I assume that after you change the grammar, you save it and start the debugging process again. You didn't mention these essential things, so I better ask.

lublak commented 4 months ago

@mike-lischke Oh, right! Sorry that I gave you this information directly. But yes, I'll start the debugging process again.

For further information, the other graphs are up to date: ATN Graph Railroad Call Graph

More information: Breakpoints are also not working at all for me at the moment. I hardly use them personally, but maybe it will help with the problem here. I leave nothing untried!

lublak commented 4 months ago

I don't know if it might be due to a vscode update. But since I reported it here, it's just that the parse tree only updates if you restart vscode completely. (Version 1.88.1, system setup)

Everything indicates that the internal grammar representation (ATN etc.) is not up to date. Needs investigation.
