AtributeError in multiple files while decompiling project

[madeddy]

Possible some intended behavior/obfuscation try by the apps devs.

Outtake from original bug report #83:

!NSFW Warning! If one try's to decompile Summertimesaga v0.19.5 i got this outcome:

Decompilation of 926 files successful, but decompilation of 269 files failed

The fail's give afaik for all the 269 fails the same error:

Error while decompiling ./rpa_extract/scripts/core/user_interface/computer/app/dir.rpyc:

Some info addition:

I compiled un.rpyc from current dev branch (used just compile.py -d) and t from the look of it the decompiling did run without errors.

However trying to run the app with the resulting *.rpy files isn't working: errors.txt I guess this is the bug from #82 though.

I looked at this closer and I think you've just made a mistake and accidentally edited sl2decompiler.py by yourself. That line is not supposed to end in .py, and it doesn't on any branches in this repo. Try redownloading unrpyc ; )

Thanks for looking into it.

Wrong. I edited nothing. However you're right that "unrpyc" wasn't at fault. A corrupt base game was the problem.

Wrong. I edited nothing.

I understand it might've not been intentional, but the error says:

  File "/home/olli/Code/rpa_tools/unrpyc-dev/decompiler/sl2decompiler.py", line 304, in print_keywords_and_children
    self.print_nodes(children_after_keywords, 0 if has_block else 1).py

While that line in the codebase on git is actually (and has been for the last 5 years).

        self.print_nodes(children_after_keywords, 0 if has_block else 1)

Notice the lack of a trailing .py, which, since it is the file extension for python files leads me to think that a silly mistake happened somewhere, but it's definitely not a fault of unrpyc.
