Crate gfx_shader_watch

Provides ability to change shader source files and have them reload on the fly. Also provides macros to simply include the shader code at compile time when running in release mode.

Examples

#[macro_use] extern crate gfx;
#[macro_use] extern crate gfx_shader_watch;

use gfx_shader_watch::*;
use gfx::Primitive;
use gfx::state::Rasterizer;

pub fn main() {
    // {code to setup window / gfx factory etc }

    // Container has SimplePsoCell or WatcherPsoCell type, depending on compile mode
    // if you need to refer to the type, use the `debug_watcher_pso_cell_type!` macro
    let mut pso_cell = debug_watcher_pso_cell!(
        pipe = mypipeline,
        vertex_shader = "shader/vert.glsl",
        fragment_shader = "shader/frag.glsl",
        factory = factory,
        primitive = Primitive::TriangleList,
        raterizer = Rasterizer::new_fill()).expect("psocell");

    let mut running = true;
    while running {
        // ...
        encoder.draw(&slice, pso_cell.pso(), &data);
        // ...
    }
}

Macros

debug_watcher_pso_cell	Returns WatcherPsoCell instance when compiled in debug mode, SimplePsoCell instance when compiled in release mode The type itself can be attained similarly with the debug_watcher_pso_cell_type macro
debug_watcher_pso_cell_type	Returns WatcherPsoCell type when compiled in debug mode, SimplePsoCell type when compiled in release mode Type will match that returned by debug_watcher_pso_cell macro

Structs

SimplePsoCell	Container with compile time shader source, pipeline state is build on initialisation
SimplePsoCellBuilder	Builds SimplePsoCell
WatcherPsoCell	Container that watches shader files and reloads pipeline state object after modification
WatcherPsoCellBuilder	Builds WatcherPsoCell

Traits

PsoCell

Container for pipeline state object and a factory
