# Upaya

> upaya: a means that goes or brings one up to some goal; skillful means

Zig-based framework for creating game tools and helper apps. Consists of the following:

- *Sokol*: used for cross-platform window creation and rendering

- *STB Image and Rect*: image loading, image saving and rect packing

- *Tiny Filebrowser*: cross-platform filebrowsers and dialogs

- *Dear ImGui*: needs no introduction

- *Known Folders*: staple of many zig codebases. See the GitHub page: [known-folders](https://github.com/ziglibs/known-folders)

Upaya provides a set of conveniences to speed up tool building:

- *upaya.fs*: one-liners for saving/loading JSON/binary files

- *upaya.mem*: C allocator and a temp allocator (just use and never free)

- *upaya.menu*: helpers for managing a main menu bar

- *upaya.colors*: ImGui color translations and helpers

- *upaya.math*: math helpers and a random number generator

## Getting Started

First fetch Upaya: `git clone --recursive https://github.com/prime31/zig-upaya/`

Zig is a fast moving target right now and Upaya uses some of the newer features in the language. You will want to be using a [nightly build](https://ziglang.org/download/) of Zig rather than an older release. Once you have zig installed, you can use `zig build help`. The available examples will be listed in the `Steps` section. `zig build run` will always build the most recent example.

## Your First Upaya App

A full basic Upaya app is below. You can start putting code right in the `update` method which will be called each frame.

```zig

const upaya = @import("upaya");

usingnamespace upaya.imgui;

pub fn main() !void {

    upaya.run(.{

        .init = init,

        .update = update,

    });

}

fn init() void {}

fn update() void {

    _ = igBegin("My First Window", null, ImGuiWindowFlags_None);

    igEnd();

}

```

## Building a Command Line App

Parts of Upaya can be used for command line tools as well. For example you may want to build a command line image manipulator that uses the STB Image and STB Image Write libs included in Upaya. To do that, the Upaya `build.zig` file has a separate method that you can use to setup the dependencies for you executable: `linkCommandLineArtifact`. When you call `linkCommandLineArtifact` it will skip linking Sokol, Dear ImGui and Tiny Filebrowser giving you a stripped down binary. Note that you must manually initialize the temp allocator by calling `upaya.mem.initTmpAllocator();` See the "texture_packer_cli" example code.
