How can I compile tjs2?

[Kein]

I know krkrz scene editor can be used to edit tjs2 but I'm trying to remove a line altogether and can't do it with krkrz scene editor. I've managed to decompile with tjs2Disassembler by xmoe but using his tjs2Compiler causes a crash without an error report.

You don't need to compile after editing TJS scripts. Just replace the file on the filesystem or the archive.

Sorry, I mean for krkrz. If it's not compiled it will give a syntax error.

Is it a half width to full width conversion error? If so, save the script in UTF-16 with BOM.

All the error says is "error at initialize line 1 Sytnax Error".

This is what the compiled and uncompiled versions look like, the second works without any problems:

I've tried ctjs2 from here too: http://www.kaede-software.com/2013/02/tjs2_3.html

But I get this error with Japanese locale:

Did you try to use KrkrExtract to decompile the script?

Yeah, it seems that is the problem. I've tried using both tjs compliers now on a decomplied startup.tjs that was included with krkr2bytecode and they compile without a problem. So I'm right now looking for a different method to decompile.

I've found out how to decompile and compile.

First, Furikiri seems to be the only decompiler that exists for tjs, everything else is a dissembler. You can learn the difference here: https://ulysseswu.azurewebsites.net/post/Furikiri

The main thing to know is that you can't use a compiler successfully on a dissembled tjs, only a decompiled one.

I have uploaded the exes here, for people who don't know how to build it: https://mega.nz/#!3HZWTS4L!CFJ2xBI8hhHCPlcLfUz2ySvD725W6MFlg4_4WpSht1o

To use girigiri.exe open the command line with shift + right click, then type "girigiri (tjs name + extension) --dec", or use --help to see all the commands.

For compiling, I recommend xmoe's compiler over the official ctjs2: https://github.com/xmoeproject/KrkrExtract/releases (download from releases and the exe will be under Tool Sources)

After you decompile you also have to change the encoding to UTF 16 (/ UCS 2) LE BOM.

Like it says on the blog post, the decompiler will not usually work if the tjs is complex but this is the only option, overall I wouldn't recommend doing this if you can use use this instead: https://github.com/marcussacana/KrKrZSceneManager

Basically you're correct, there is no "TJS2 decompiler"(*) other than my Furikiri. But Furikiri is not finished (the TJS2 language is a bloated, badly-implemented language after all), and currently the decompilation result can only be used as a reference of TJS2 bytecode's behaviour - that's already useful in my cases. You cannot expect the decompilation result can be directly compiled again, it's impossible for now.

However, it might be more practical to implement a tool to compile the disassmbled assembly. Furikiri has a plan (issue) to do that, but I currently just focused on decompilation.

Furikiri also provides the fastest TJS2 disassemble feature - definitely faster and more complete than the official one. That's the main feature of girigiri for now.

(*): Xmoe said on weibo (at 2019-5-25) that he will release a tjs decompiler after a while. Maybe he can make a better tool than my shit
