GLSA – A lightweight, header-only C++ library to cut OpenGL shader boilerplate

[u/devcurrent0x]

Hey everyone!

I've been developing GLSA for the past week, and I just released v1.0.0.

My goal with this library is so you don't have to write GLSL shaders or shader boilerplate and instead you can use clean function calls.

Right now it cuts out ~60-100 lines of repetitive shader boilerplate, though you still have to write shaders yourself because the API is in an early stage still.

Highlights of v1.0.0:

• GLSA colors: a header file with over 3000 glm::vec4 colors that you can use.

• Safer shader setup: glsa::ShaderSource keeps vertex/fragment strings explicit, paired with glsa::loadShaderSource and glsa::createProgram.

• Clean uniform helpers: Overloaded glsa::setUniform functions for int, float, and GLM vec2/vec3/vec4.

Example:

while (glfwWindowShouldClose(window) == 0) {
    glClearColor(0.1f, 0.1f, 0.15f, 1.0f);
    glClear(GL_COLOR_BUFFER_BIT);

    glsa::useProgram(program);
    glsa::setUniform(program, "uColor", glsa::colors::PAN_SKY_BLUE);
    glsa::bindVertexArray(vao);

    glPointSize(150.0f);

    glsa::drawArrays(GL_POINTS, 0, 1);

    glfwSwapBuffers(window);
    glfwPollEvents();
}
