[WIP] Caprica Papyrus Compiler

[Orvid]

Because I'm not a patient enough person to wait for the Creation Kit to come out, I went and wrote my own Papyrus compiler. Available on the nexus here, it supports what I believe to be the syntax for the new features present in FO4, and, as of v0.0.4 can also disassemble and re-assemble .pex files.

 

The Caprica compiler is also far faster than the CK compiler, as it is able to compile all 2.4k scripts for Fallout 4 in just over 8 seconds on my computer when compiling one file at a time, and 4 seconds when parallel compilation is enabled. (the current releases have parallel compilation disabled, but there will eventually be a command-line option to enable it)

 

Feel free to leave any feedback you have on it here, on the mod page, or on Github.

I am flabbergasted that this hasn't been getting more attention. A working Papyrus compiler opens up enormous new horizons for pre-Creation Kit modding. Even something as simple as Power Armor Delivery would have been impossible without it.

Could someone please explain how I can convert my psc file into something that the game could use, like say a .pex file?

You have to use cmd. Best write yourself a small batch file. Here is mine, just edit the paths:

@echo off

set compdirectroy="D:\Modding\Fallout4\Tools\ScriptCompiler"
set srcdirectory="D:\Modding\Fallout4\Data\Scripts\src"
set bindirectory="D:\Modding\Fallout4\Data\Scripts"
set fo4scriptdirectoy="D:\Steam\steamapps\common\Fallout 4\Data\Scripts"

:start
echo Enter filename without extension:
set /p filename=

cd %compdirectroy%
caprica.exe "%srcdirectory%\Custom\%filename%.psc" -i "%bindirectory%" -o "%bindirectory%\Custom" --champollion-compat yes --allow-compiler-identifiers

echo Copy compiled .pex to scripts directory? (y/n)
set /p bCopyToFO4=

if "%bCopyToFO4%" == "y" (
	copy %bindirectory%\Custom\%filename%.pex %fo4scriptdirectoy%
	copy %srcdirectory%\Custom\%filename%.psc %fo4scriptdirectoy%\src\DarthWayne
)
pause
cls
goto start

Edit: This bat compiles only compiles psc files in subfolder named "Custom". It can also cause problems if you have blanks in your paths...

I've tried to troubleshoot, but it keeps giving me this error

 

Enter filename without extension: QF_MS17_00022A08

Compiling C:\Users\eric\Desktop\psctopex\src\QF_MS17_00022A08.psc

Compilation failed, 0 warnings and 1 errors were encountered.

Copy compiled .pex to scripts directory? (y/n)

Here is my batch file

 

 

echo off

set compdirectroy="C:\Users\eric\Desktop\psctopex\"
set srcdirectory="C:\Users\eric\Desktop\psctopex\src"
set bindirectory="C:\Users\eric\Desktop\psctopex\bin"
set fo4scriptdirectory="CC:\Program Files (x86)\Steam\steamapps\common\Fallout 4\Data\scripts"

:start
echo Enter filename without extension: QF_MS17_00022A08
set /p filename=

cd %compdirectroy%
caprica.exe "%srcdirectory%" -i "%bindirectory%" -o "%bindirectory%" --champollion-compat yes --allow-compiler-identifiers

echo Copy compiled .pex to scripts directory? (y/n)
set /p bCopyToFO4=

if "%bCopyToFO4%" == "y" (
	copy %bindirectory%\QF_MS17_00022A08.pex %fo4scriptdirectoy% 
	copy %srcdirectory%\QF_MS17_00022A08 %fo4scriptdirectoy%
)
pause
cls
goto start

What did I do wrong?

[Orvid]

The issue is that QF_MS17_00022A08.psc needs to be Fragments/Quests/QF_MS17_00022A08.psc
