Tool Ren'Py UnRenGUI, UnRen-forall(v9.4), UnRen-Powershell-forall(v9.4), UnRen-old

[joelurmel]

Good morning, good afternoon, or good evening. I don't know if it works that way for him, but when I try to use this new version in Renpy 7.4 to 8.0 games, it shows the rpyc files but closes the program. In the forall version (v9.4) (240216), they extract normally without closing, but it doesn't work in Renpy 8.4

The temporary fix for 8.4 have a side effect for older Ren'Py.
So, use the previous version for Ren'Py 7 and the new with Ren'Py 8.4.*.

Summertime Saga can be decompiled with 9.6.48, but some script files were decompiled incorrectly and failed to execute.
Thanks for the updated tool by the way.

I know, but no solution for now, sorry

A favor...
Could you please upload your version of the decompiler somewhere or at least cite the changed code areas? I'm curious what you tried and i don't want to go and dismantle first you unren variant just to see it.

What Ren'Py version has Summertimesaga? Keep also im mind they heavily modify the engine, so decompiling could be never possible... Better users ask the devs for the sources if a good enough reason.

Joined the modified version and Summertime Saga use now 8.4.1.
And the log for some rpyc files, seems to have new objects that are not taken right.

Thanks.

AttributeError: 'Scene' object has no attribute 'imspec'

I fixed this one with a short hack to see what happens and in the next run 27 other files acted up instead...

So, i think there is possible more modified on this game as just a new Ren'Py. You could compare with another v8.4.1 game to see from "what" exactly the errors come.

# FYI short fix:
# __init__.py Line 234:

if hasattr(ast, "imspec") and ast.imspec is None:

There is more wrong if ast.imspec is accessed but as said we need another game with this engine version. If this problem persists, we can add it on GH too the error issue.

 

[joelurmel]

We need your help to try to properly support Ren'Py games in version 8.4.1.
Can you give me a game using Ren'Py 8.4.1 for testing.
For now, we know One Week Away 0.4 and Summertime Saga 21.0.0

Tried the short fix with OurBrightDays-0.2.0 which use Ren'Py 8.4 and still have error with imspec

And the game does not start with this errors

 

[Madeddy]

Tried the short fix ... and still have error with imspec

Already known. You missed perhaps i mentioned this already in my post above.

I overlooked how ast.imspec is multiple times used, so the hasattr check i used isn't enough. Try to write the line instead with
if not getattr(ast, "imspec", None):
Edit: Warning, this is just a hack to see where things lead, even if this works. There is a better solution.

But as said i get also multiple errors with

AttributeError: 'ArgumentInfo' object has no attribute 'extrapos'

and thats old friends from a few years back. Apparently they changed them again, unrpyc mistakes these code parts as older Ren'Py versions and forks in the false handling mechanic. ATM i have no ideas how to circumvent this as it got again more complicated.

After inspecting the new rpyc v2, there is no more imspec in the scene struct. You have only
linenumber, col_offset, filename, name_version, name_serial, layer.

OK. The state of things, as i see it, is:

• "<class 'renpy.astsupport.PyExpr'> was instantiated with unexpected arguments": was already in Jan'25 reported and solved:
  You must be registered to see the links
• if block missing: PyExpr lives from v8.4 on in the module "astsupport" so in unrpyc it just needed to be added as seen here: https://f95zone.to/threads/unrengui...ell-forall-v9-4-unren-old.92717/post-17655202 This works AFAIK.
• imspec attr in class Scene can now be missing instead just empty: The nasty hacks i did with hasattr/getattr showed its the same root cause as already in January:
  You must be registered to see the links
  solved this the same way
• language attr in class TranslateString now missing: solved, see above
• Class ArgumentInfo attributes changed: (maybe i solved it and someone else used already the same code)
  • arguments can now be a empty tuple instead None
  • starred_indexes can be completely missing
  • doublestarred_indexes can be completely missing
• So far unknown AST changes(?) which lead to these errors on game exec:

Ok. I figured out whats wrong with the bugs in my last bulled point:
The error roots in sl2decompiler.py in the class SLUse and is related to the move of PyExpr from module ast to astsupport. We import there just the old style PyExpr, but the new one appears there now also and it uses (logically) the wrong code for such appearances, because unrpyc supports it so far not.

So, just a bit more work needed to figure out how to deal with both variants. Yeah, soooooooo fun! </sarcasm-node=off>

Ok, i think/hope i got it. Three of the games above, including STS, decompiling with this clean and run also fine! All new fixes are in here:

Thanks for the great work, BUT... it unpacks without errors, but there is one nuance: for some reason, it doesn't work correctly with the menus. Here's an example of what it should be and what it is. The selection conditions are lost. STS (game\src\plot\judith.rpyc)

 

[Madeddy]

Right. I have this errors here also in my files. Thanks for bringing it to attention kwazimoda.
Something, somewhere is still skipped for some reason. Well shit. You all know the saying about "finding the needle in a haystack", right? The problem with this error is: I don't even know what our needle is or how it looks.

Edit: Found the needle, fixed. Was way easier then thought. Updated the PR on Github. (see post 1521)

After decompiling the game High Scool Days, this error appears when launch the game. The decompiler report shows that it was decompiled correctly.
