# Boomer
|
|
|
|
|
|
|
|
Zoomer application for Linux.
|
|
|
|
- Development is done on https://twitch.tv/tsoding
|
|
- Archive of the streams: https://www.twitch.tv/collections/HlRy-q69uBXmpQ
|
|
|
|
## Dependencies
|
|
|
|
### Debian
|
|
|
|
```console
|
|
$ sudo apt-get install libgl1-mesa-dev libx11-dev libxext-dev libxrandr-dev
|
|
```
|
|
|
|
## Quick Start
|
|
|
|
```console
|
|
$ nimble build
|
|
$ ./boomer --help
|
|
$ ./boomer # to just start using
|
|
```
|
|
|
|
## Developer Capabilities
|
|
|
|
For additional Developer Capabilities compile the application with the following flags:
|
|
|
|
```console
|
|
$ nimble build -d:developer
|
|
```
|
|
|
|
This will enable reloading the shaders with `Ctrl+R`. The shader files (`frag.glsl` and `vert.glsl`) should be located in the same folder as `boomer.nim` for this feature to work. If the shader files not found the program won't even start.
|
|
|
|
**Keep in mind that the developer build is not suitable for day-to-day usage because it creates the external dependency on the shader files. Compiling the program without `-d:developer` "bakes" the shaders into the executable and eliminates the dependency.**
|
|
|
|
## Controls
|
|
|
|
| Control | Description |
|
|
|-------------------------------------------|---------------------------------------------------------------|
|
|
| <kbd>0</kbd> | Reset the application state (position, scale, velocity, etc). |
|
|
| <kbd>q</kbd> or <kbd>ESC</kbd> | Quit the application. |
|
|
| <kbd>r</kbd> | Reload configuration. |
|
|
| <kbd>Ctrl</kbd> + <kbd>r</kbd> | Reload the shaders (only for Developer mode) |
|
|
| <kbd>f</kbd> | Toggle flashlight effect. |
|
|
| Drag with left mouse button | Move the image around. |
|
|
| Scroll wheel or <kbd>=</kbd>/<kbd>-</kbd> | Zoom in/out. |
|
|
| <kbd>Ctrl</kbd> + Scroll wheel | Change the radious of the flaslight. |
|
|
|
|
## Configuration
|
|
|
|
Configuration file is located at `$HOME/.config/boomer/config` and has roughly the following format:
|

<param-2> = <value-2>
|
|
# comment
|
|
<param-3> = <value-3>

| Name | Description |
|
|
|----------------|----------------------------------------------------|
|
|
| min_scale | The smallest it can get when zooming out |
|
|
| scroll_speed | How quickly you can zoom in/out by scrolling |
|
|
| drag_friction | How quickly the movement slows down after dragging |
|
|
| scale_friction | How quickly the zoom slows down after scrolling |
|
|
|
|
## Experimental Features Compilation Flags
|
|
|
|
Experimental or unstable features can be enabled by passing the following flags to `nimble build` command:
|
|
|
|
| Flag | Description |
|
|
|---------------|--------------------------------------------------------------------------------------------------------------------------------|
|
|
| `-d:live` | Live image update. See issue [#26]. |
|
|

|
|
| `-d:select` | Application lets the user to click on te window to "track" and it will track that specific window instead of the whole screen. |
