dxbc_reader - DXBC to readable HLSL translator
[feature] easy to use & easy to read
[usage]
Run from project root directory:
.\lua\lua.exe dxbc_reader.lua example/fragment.txt -o dxbc.out
Options:
-o, --output Output filename (default: {input}.hlsl)
-d, --debug Enable debug info (use -d t for verbose dump)
-p, --print Print result to stdout (default: true, use -p false to suppress)
[dependencies]
- Lua 5.1+ (or LuaJIT)
- LPeg (lua-pattern-matching)
- argparse (included in lua/)
Optional: crypt (for lua/to_base64.lua, not required for main flow)
[testing]
.\lua\lua.exe run_tests.lua
