Thanks for your feddback, a commit a08b019 may improved this issuse, could you please follow the install from the lastest source code and try again.

Hello, I’ve added some adjustments for Ren'Py 8.4 compatibility. You can try again using the latest code.

[cnfatal]

@JoeLurmel Hi , I have been able to successfully decompile and run the summertimesaga, you can also try it, wish you good luck.

@JoeLurmel Hi , I have been able to successfully decompile and run the summertimesaga, you can also try it, wish you good luck.

There are still errors in the version decompiled, like tabulation shortened 2 spaces instead of 4.
Arguments after image not always restaured, like
show anon at right with dissolve.nowait
and in your version
show anon
with dissolve.nowait

rpycdec.zip
This zip have the original rpy named .org provided by the dev and the rpy decoded with the current version from the source

Oh, awesome — thanks for providing the original code example! I’ve fixed that issue in the latest commit. If you run into any further problems, just let me know.

[JoeLurmel]

There is always a problem with empty lines. Some are added when others are not restored.

It does not impact the game, except when you use translation via game/tl/language.
Because PID is constructed with the line number, and it does not match if the script stays in an RPA archive.

[cnfatal]

After renpy is compiled, comments, blank lines, and indentation are irrecoverable. While line numbers can be used, considering them would add additional complexity to the decompilation logic, so I intentionally omitted them.
Blank lines in the decompiled file are manually added, always adding a new line after the python: block.

It does not impact the game, except when you use translation via game/tl/language. Because PID is constructed with the line number, and it does not match if the script stays in an RPA archive.

I'm not a renpy expert, is the PID in the example below the identifier "start_bd1ad9e1"?

# game/script.rpy:99
translate piglatin start_bd1ad9e1:
    # e "We aim to provide a comprehensive framework for translating dialogue, strings, images, and styles."
    e "Eway aimway otay ovidepray away omprehensivecay ameworkfray..."
    e "...orfay anslatingtray ialogueday, ingsstray, imagesway, andway ylesstay."

The identifier generate by code like:

    def create_translate(self, block):
        """
        Creates an ast.Translate that wraps `block`. The block may only contain
        translatable statements.
        """

        md5 = hashlib.md5()

        for i in block:
            code = i.get_code()
            md5.update((code + "\r\n").encode("utf-8"))

        digest = md5.hexdigest()[:8]

        identifier = self.unique_identifier(self.label, digest)

The reason for the inconsistent identifiers may be that get_code in Renpy SDK and get_code in rpycdec return different contents. In Renpy SDK, only Say and UserStatement implement get_code. If this is the case, I would check the differences between rpycdec's implementation and Renpy SDK to ensure that the results are consistent to avoid different identifiers. If all goes well, tl can work normally.

How? I basically tried anything and can't do it.
