# SHDRR: Live shader compiler 

[![Crates.io](https://img.shields.io/crates/v/shdrr.svg)](https://crates.io/crates/shdrr)

[![Build Status](https://travis-ci.org/maeln/shdrr.svg?branch=master)](https://travis-ci.org/maeln/shdrr)

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](https://github.com/google/shaderc).

Right now, it detect the shader type (compute, vertex, fragment) using the file extension:

- *.cs -> compute

- *.fs -> fragment

- *.vs -> vertex

## Usage

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                  

            Directory with the shaders

    -e                  

            This option let you choose the target environnement for Shaderc, 

                        

                        Accepted value are: 

                        vulkan, opengl, opengl_compat [default: vulkan]

    -O         

            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 directory

    -s                

            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`

## Installation

With `cargo`:

```

cargo install shdrr

```
