This setup runs scc.exe to export script source file info for use with the redscript decompiler (namely this branch - a binary of this is included at tools/redscript-cli.exe) to generate fully decompiled redscript files.
The workflow replaces tools/redmod/bin/redlexer_native.dll and expects the old one to exist at tools/redmod/bin/redlexer_native_real.dll - the CMake target compile does this all automatically (including putting the old one back in place).
Below is the compile command you can run manually to test it out (it creates a final.redscripts in the redmod directory):
scc.exe -compile "C:\Program Files (x86)\Steam\steamapps\common\Cyberpunk 2077\tools\redmod\scripts\" "C:\Program Files (x86)\Steam\steamapps\common\Cyberpunk 2077\tools\redmod\final.redscripts" -rttiSchemaPath "C:\Program Files (x86)\Steam\steamapps\common\Cyberpunk 2077\tools\redmod\metadata.json" -Wnone -threads 4 -no-testonly -no-breakpoint -profile=off
The decompile target uses the included tools/redscript-cli.exe to decompile the compiled final.redscripts into redscripts/.
