**It is recommended to clean the cache in a new major and minor release** _but is not required_

## Features
- Sets terminal colors sequences on all active terminals
- Config file at `~/.config/wallust/wallust.toml` (documented in the sample `wallust.toml` of this repo):
	* templating integrated in a config file
	* backends, colorspaces and filters
	* configurable threshold
- Cache scheme palette at `~/.cache/wallust`

### Terminal color sequences
By default, `wallust` will send these sequences to all open terminals
(/dev/pts/). You can skip this with the `-s` or `--skip-sequences` flag.

When opening new terminals you will notice that the color sequences are not
applied. To solve this you can send the sequences yourself when your shell
opens. `wallust` will store the sequences in `~/.cache/wallust/sequences`, so
the usual way is to `cat ~/.cache/wallust/sequences` in your `.zshrc`,
`.bashrc`, etc.

### Templating & Config File
You can use `wallust` generated colors in a program by _templating_ the colors
in it's config file, like the following example:
```
# zathurarc config file

#keybindings
...

# colors
set default-bg     "{color2}"
set default-fg     "{foreground}"
set statusbar-bg   "{color4}"
set statusbar-fg   "{color6}"
set inputbar-bg    "{color1}"
```
Then add this file to `~/.config/wallust/` (e.g. _~/.config/wallust/zathurarc_)
and add a new entry to `wallust.toml`
```toml
[[entry]]
template = "zathurarc"
target = "~/.config/zathura/zathurarc"
```

**NOTE:** The template name doesn't have to match the target name: e.g. the
file could be named `sample.conf`, and thus the entry would have `template =
"sample.conf"`, but the target can remain the same, e.g. `target = "~/.config/zathurarc"`.

## Usage
```
wallust my_wallpaper.png
```

## Installation
```
cargo install wallust
```

or, if you cloned the repo
```
cargo install --path .
```
or just build it (`cargo build --release`) and copy the binary to one folder
present in your `$PATH` like `/usr/local/bin`
```
cargo build --release
cp -f ./target/release/wallust /usr/local/bin
```

### NetBSD
If you are using NetBSD, a native package is available from the official repositories. To install it, simply run:
```
pkgin install wallust
```

## TODO
for more, grep the src for TODO `rg TODO`
- **release binaries** - figure out woodkeeper codeberg CI
- Think about using [k means algo](https://en.wikipedia.org/wiki/K-means_clustering)
  similar to [pigmnts](https://github.com/blenderskool/pigmnts) (just without seg faulting :p)
