SHDRR is a live shader compiler, as in, it will automatically detect if a file changed within a directory and recompile it to SPIR-V using shaderc.
Right now, it detect the shader type (compute, vertex, fragment) using the file extension: - *.cs -> compute - *.fs -> fragment - *.vs -> vertex
See shdrr --help for usage:
```
SHDRR: Live compiler for SPIRV based on shaderc.
USAGE: shdrr [FLAGS] [OPTIONS]
FLAGS:
-h, --help
Prints help information
-r
Look for shader file recursively
-V, --version
Prints version information
-v
Verbose output
OPTIONS: -d
-e <env>
This option let you choose the target environnement for Shaderc,
Accepted value are:
vulkan, opengl, opengl_compat [default: vulkan]
-O <optimization>
The optimization level follow the ones used by shaderc:
1 or nothing is performance optimization,
0 is no optimization for debugging,
s is optimization for size. [default: 1]
-o <output>
Output directory
-s <spirv>
This option let you choose the SPIR-V version to be used for the compiled shader,
Accepted value are: 1.0, 1.1, 1.2, 1.3, 1.4 [default: 1.0]
```
Exemple: To compile every shader contained in the directory ./shaders/src and its sub-directory to .shaders/bin, with verbosity:
shdrr -rv -d shaders/src -o shaders/bin
With cargo:
cargo install shdrr
