# Nuklear
|
|
This is a minimal state immediate mode graphical user interface toolkit
|
|
written in ANSI C and licensed under public domain. It was designed as a simple
|
|
embeddable user interface for application and does not have any dependencies,
|
|
a default renderbackend or OS window and input handling but instead provides a very modular
|
|
library approach by using simple input state for input and draw
|
|
commands describing primitive shapes as output. So instead of providing a
|
|
layered library that tries to abstract over a number of platform and
|
|
render backends it only focuses on the actual UI.
|
|
|
|
## Features
|
|
- Immediate mode graphical user interface toolkit
|
|
- Single header library
|
|
- Written in C89 (ANSI C)
|
|
- Small codebase (~17kLOC)
|
|
- Focus on portability, efficiency and simplicity
|
|
- No dependencies (not even the standard library if not wanted)
|
|
- Fully skinnable and customizable
|
|
- Low memory footprint with total memory control if needed or wanted
|
|
- UTF-8 support
|
|
- No global or hidden state
|
|
- Customizable library modules (you can compile and use only what you need)
|
|
- Optional font baker and vertex buffer output
|
|
|
|
## Building
|
|
This library is self contained in one single header file and can be used either
|
|
in header only mode or in implementation mode. The header only mode is used
|
|
by default when included and allows including this header in other headers
|
|
and does not contain the actual implementation.
|
|
|
|
The implementation mode requires to define the preprocessor macro
|
|
`NK_IMPLEMENTATION` in *one* .c/.cpp file before `#include`ing this file, e.g.:
|
|
```c
|
|
#define NK_IMPLEMENTATION
|
|
#include "nuklear.h"
|
|
```
|
|
IMPORTANT: Every time you include "nuklear.h" you have to define the same optional flags.
|
|
This is very important not doing it either leads to compiler errors or even worse stack corruptions.

## Example
|
|
```c
|
|
/* init gui state */
|
|
struct nk_context ctx;
|
|
nk_init_fixed(&ctx, calloc(1, MAX_MEMORY), MAX_MEMORY, &font);
|
|
|
|
enum {EASY, HARD};
|
|
int op = EASY;
|
|
float value = 0.6f;
|
|
int i = 20;
|
|
|
|
if (nk_begin(&ctx, "Show", nk_rect(50, 50, 220, 220),
|
|
NK_WINDOW_BORDER|NK_WINDOW_MOVABLE|NK_WINDOW_CLOSABLE)) {
|
|
/* fixed widget pixel width */
|
|
nk_layout_row_static(&ctx, 30, 80, 1);
|
|
if (nk_button_label(&ctx, "button")) {
|
|
/* event handling */
|
|
}
|
|
|
|
/* fixed widget window ratio width */
|
|
nk_layout_row_dynamic(&ctx, 30, 2);
|
|
if (nk_option_label(&ctx, "easy", op == EASY)) op = EASY;
|
|
if (nk_option_label(&ctx, "hard", op == HARD)) op = HARD;
|
|
|
|
/* custom widget pixel width */
|
|
nk_layout_row_begin(&ctx, NK_STATIC, 30, 2);
|
|
{
|
|
nk_layout_row_push(&ctx, 50);
|
|
nk_label(&ctx, "Volume:", NK_TEXT_LEFT);
|
|
nk_layout_row_push(&ctx, 110);
|
|
nk_slider_float(&ctx, 0, &value, 1.0f, 0.1f);
|
|
}
|
|
nk_layout_row_end(&ctx);
|
|
}
|
|
nk_end(&ctx);
|
|
```

Big thank you to Omar Cornut (ocornut@github) for his [imgui](https://github.com/ocornut/imgui) library and
|
|
giving me the inspiration for this library, Casey Muratori for handmade hero
|
|
and his original immediate mode graphical user interface idea and Sean
|
|
Barret for his amazing single header [libraries](https://github.com/nothings/stb) which restored my faith
|
|
in libraries and brought me to create some of my own.
