Lua Decompiler LuaDC Beta 0.9.20; Now with wildcards in commandline

[Demon_Eyes]

Just wanted to say great work Age2uN, your work is greatly appreciated.

[Crook]

I'd like to see a complete, every LUA decompiled ZIP. Is there a way to do this easily, or is someone working on it? An entire lua decompile of the big.

Most of them are in the "Data" directory of the RDN Tools.

[Demon_Eyes]

if the decompiler can work of directory lists then you could just make a batch file for it, atleast that would be my best suggestion/idea.

Anybody managed to decompile the soundscripts files without error? The game crash when I try to load them...?

Which ones exactly do crash your game (look into homeworld2\bin\release\hw2.log) ?
Have you used the latest LuaDC (version 0.9.6) ?

[Riker2600]

All 4 files in Speechlogic, which are status, commands, eventtext and chatter. When chatter is revmoved, the game load, but some sounds aren't played, I've tried loading each files one at a time, but when quitting the game and looking at the HW2log, there is some missing elements written there.

I'm using the latest version of LuaDC...

[Age2uN]

Hi Riker,

Version 0.9.10 online now translates these files OK!

Ok, I've decompiled the files with the latest version, now the game load without crash, but no sounds are played when selecting units, etc..

Here's what the log says:

The problem seems to be with chatter.lua...

thanks for your efforts

[Age2uN]

Hi Riker,

I located the problems.
They are not in chatter but in status.lua and commands.lua,
which get called by chatter somehow.
I'll fix that tomorrow (too tired now).

[Age2uN]

phew,
this was a hard one.
These scripts command.lua etc. in soundscripts directory
do a weird nesting of "if then else end"s.
I had to fight with them hard !
but now LuaDC decompiles them smothly !
So Riker: give it a try ...

[Riker2600]

It works!! Great work Age2uN!!

Now, my new units will have their own sound files!! I'm really happy, thanks a lot Age2uN...

[pantner]

i think it would be REALLY helpful to have a *.* function added in....

ie. you type in

LuaDC *.lua* -o

and it decompiles all lua files in the directory, plus it overwrites the old ones......

[Age2uN]

Version 0.9.20 does work with wildcards now.
So you can issue a command like:
LuaDC *.lua
LuaDC *.ship
....
and get all the files matching the wildcard translated at once.

Yes, but not all. It's a task that only needs doing the once, and we need never bother about lua decompiling again.

[pantner]

YES!!!!

Thats just what i wanted!

[Tel'Quessir]

Hmm, does it support .level files yet? Decoded multiplayer maps refuse to work.

SP Campaign supported? I'll try that - some editing for mod improvement is necessary.

[Tefeari]

I think so... But if it doesn't Thought made a level decompiler a long time ago called Balcora Gate, it also decompiles FX and Nebula scripts.

I've noticed, that in a lot of the decoded Campaign levels, there is a missing "}" in a lot of the Dust Clouds and Nebulae. I don't know if that's an error on the part of LuaDC, ot if that's the way they really are. Anyway, you have to fix those before you can get them to work.

[Tefeari]

I suppose balcora gate is better for that then.

hey guys i wrote a .bat file that makes this stuff a LOT easier, u just drag any file over the batch file and it automatically decompiles with this program without needing to enter the command line directly... you just need to put the EXE and this batch into C:\Program Files\Sierra\LuaC\ and then POOF it works u can set a shortcut to the batch file and put that on desktop its very easy..... output file goes to wherever the file is that you dragged on to it!

here is the batch file:

echo off
cd \
copy %1 "C:\Program Files\Sierra\LuaC\translate.lua"
cls
cd "C:\Program Files\Sierra\LuaC\"
echo Please wait while your LUA file is translated . . .
LuaDC translate.lua
copy translate.lua.LuaDC %1.out
del translate.lua
del translate.lua.LuaDC
cls
echo Please wait while your LUA file is translated . . .  Translation Complete!
echo Thank you for using the LuaDC command-line assistant
echo,
pause

pretty simple... age add credits if u want whatever but this makes a LOOOOOOT easier.

P.S. yes i mean sierra\luaC not luaDC

[Riker2600]

Age2uN: I've just realised that the decoded version of Status.lua in Speechlogic doesn't seems to work, any changes I make in the file don't make it ingame, however, the game doesn't crash and I see no error message in the Log.

But when I remove the file, all sounds that should be loaded with status.lua play...??

[Demon_Eyes]

also, when you gonna upload 9.20 ?!

[BlueTech]

hey hey mikail that was MY idea i was spammin spooky to put in auto LUA decompilation even before this was made, stop stealin my ideas :P

so anyone using my batch file yet??

[Mikali]

I was wondering if you could include the option of expanding all tables so that there is only one entry per line, and brackets are all on their own line and indented properly.
A lot of the tables in the source are all on one line...
[edit] Also, if you could make it so that when a function is called from within a pair of quotes, the quotes are replaced by "[[" and "]]", it would be great.
E.g.,

"Sensors_EnableCameraZoom( 0 )",

becomes

[[Sensors_EnableCameraZoom( 0 )]],

[Mikali]

so anyone using my batch file yet??

It's not working for me. What operating system are you using?

[Skrollster]

Will this decompiler work on other .lua scripts/programs?
i tried it with a DirectConnect script for ptokax but it didn't work..

[CQD]

I think you can try this batch file. It can decompile mutiple files in one shoot.

Creat a .bat file like this:

@echo off
:start
if (%1)==()  goto end

:go
X:\WHEREYOUPUTLUADC\LuaDC %1 -o
shift
goto start

:end
@echo on

X:\WHEREYOUPUTLUADC\ is the complete path of your LuaDC.exe. Now drag about twenty or thirty files into this batch file, and it will automatically decompile them. It can't accept too much files each time, I guess it's becouse length of arguments is not unlimited.

There is another problem with it. After "tons" of drag-and-decompile operation(about 2500 files decompiled), my computer become very unstable. File Explorer does not work well so I must reboot. I think it's a windows bug(unlikely), or my script/LuaDC left some trash in memory.


----
Oh, i've put everything I decompiled here:
http://w3.nctu.edu.tw/~u8912009/hsmcDL/Data_11.zip

It should contain every single script in homeworld2.big(v1.1). Notify me if any one is missing or not decompiled...

[lurkily]

Mikail, you WILL have to edit that .bat file to match your directory for LuaDC. For instance, I put LuaDC directly into my Data directory(Where I use it - I keep a "BIG" directory under data, with all the data files directly taken from the BIG).

So in my file, instead of
copy %1 "C:\Program Files\Sierra\Homeworld2\LuaDC\translate.lua"
I used
copy %1 "C:\Program Files\Sierra\Homeworld2\Data\translate.lua"

Bluetech, wouldn't it be more helpful to use
copy %1 %1.bak
Before using
copy translate.lua.LuaDC %1

?

For those unfamiliar with .bat files, it would make a backup of the original, compiled file, then overwrite the original with the decompiled version. So you'd have file.lua(decompiled), and file.lua.bak(compiled).

Finally, what I really wanted to post. .bat files are great, yeah, but can anybody figure out how to recursively decode all the files in a directory tree? That is, decompile *.* in c:/sierra/data/BIG/, and in c:/sierra/data/BIG/ai, /art, /leveldata, /missile, /scripts, /scripts/building and research, etc etc etc etc? I've never been a heavy-duty programmer, but is it so difficult to get the program to search the directory tree?

It was one of my favorite features of the HW1 .big editor, being able to get it to save entire chunks of data files at once . . .

And . . . is it just me, or does this smiley look almost pornographic?

hmm it doesn't seem to create file paths correctly in .anim files.

when I try to make custom sprite animations it gets an invalid file reference (fxtool also cannot find the file.)

technically .anim files are .lua files but renamed (art/fx/)

if you could look into this it would help a lot.

[Ghent]

Isn't there a |tree piping command/filter you can use in bat files or DOS commands?
