# Termbox2 renderer demo
Terminal-based renderer using [termbox2](https://github.com/termbox/termbox2)
This demo shows a color palette and a few different components. It allows
changing configuration settings for colors, border size rounding mode,
characters used for borders, and transparency.
```
Keybinds:
c/C - Cycle through color modes
b/B - Cycle through border modes
h/H - Cycle through border characters
i/I - Cycle through image modes
t/T - Toggle transparency
d/D - Toggle debug mode
q/Q - Quit
```
Configuration can be also be overriden by environment variables:
- `CLAY_TB_COLOR_MODE`
- `NORMAL`
- `256`
- `216`
- `GRAYSCALE`
- `TRUECOLOR`
- `NOCOLOR`
- `CLAY_TB_BORDER_CHARS`
- `DEFAULT`
- `ASCII`
- `UNICODE`
- `NONE`
- `CLAY_TB_IMAGE_MODE`
- `DEFAULT`
- `PLACEHOLDER`
- `BG`
- `ASCII_FG`
- `ASCII`
- `UNICODE`
- `ASCII_FG_FAST`
- `ASCII_FAST`
- `UNICODE_FAST`
- `CLAY_TB_TRANSPARENCY`
- `1`
- `0`
- `CLAY_TB_CELL_PIXELS`
- `widthxheight`
## Building
Build the binary with cmake
```sh
mkdir build
cd build
cmake ..
make
```
Then run the executable:
```sh
./clay_examples_termbox2_demo
```

# Termbox2 renderer demo
Terminal-based renderer using [termbox2](https://github.com/termbox/termbox2)
This demo shows a color palette and a few different components. It allows
changing configuration settings for colors, border size rounding mode,
characters used for borders, and transparency.
```
Keybinds:
c/C - Cycle through color modes
b/B - Cycle through border modes
h/H - Cycle through border characters
i/I - Cycle through image modes
t/T - Toggle transparency
d/D - Toggle debug mode
q/Q - Quit
```
Configuration can be also be overriden by environment variables:
- `CLAY_TB_COLOR_MODE`
- `NORMAL`
- `256`
- `216`
- `GRAYSCALE`
- `TRUECOLOR`
- `NOCOLOR`
- `CLAY_TB_BORDER_CHARS`
- `DEFAULT`
- `ASCII`
- `UNICODE`
- `NONE`
- `CLAY_TB_IMAGE_MODE`
- `DEFAULT`
- `PLACEHOLDER`
- `BG`
- `ASCII_FG`
- `ASCII`
- `UNICODE`
- `ASCII_FG_FAST`
- `ASCII_FAST`
- `UNICODE_FAST`
- `CLAY_TB_TRANSPARENCY`
- `1`
- `0`
- `CLAY_TB_CELL_PIXELS`
- `widthxheight`
## Building
Build the binary with cmake
```sh
mkdir build
cd build
cmake ..
make
```
Then run the executable:
```sh
./clay_examples_termbox2_demo
```
