[`cointop`](https://github.com/miguelmota/cointop) is a fast and lightweight interactive terminal based UI application for tracking and monitoring cryptocurrency coin stats in real-time.

The interface is inspired by [`htop`](https://en.wikipedia.org/wiki/Htop) and shortcut keys are inspired by [`vim`](https://en.wikipedia.org/wiki/Vim_(text_editor)).

## Colorschemes

cointop supports custom colorschemes (themes).

<img src="https://user-images.githubusercontent.com/168240/59164231-165b9c80-8abf-11e9-98cf-915ee37407ff.gif" alt="cointop colorschemes" width="880" />

To use standard colorschemes, clone the [colors](https://github.com/cointop-sh/colors) repository into the config directory:


```bash
$ cd ~/.cointop
$ git clone git@github.com:cointop-sh/colors.git
```

Then edit your config `~/.cointop/config.toml` and set the colorscheme you want to use:

```toml
colorscheme = "<colorscheme>"
```

The colorscheme name is the name of the colorscheme TOML file.

For example, if you have `matrix.toml` in `~/.cointop/colors/` then the `colorscheme` property should be set to:

```toml
colorscheme = "matrix"
```

Alternatively, you can run cointop with the `--colorscheme` flag to set the colorscheme:

```bash
$ cointop --colorscheme matrix
```

To create your own colorscheme; simply copy an existing [colorscheme](https://github.com/cointop-sh/colors/blob/master/cointop.toml), rename it, and customize the colors.

## Config

The first time you run cointop, it'll create a config file in:

```
~/.cointop/config.toml
```

You can then configure the actions you want for each key:

(default `~/.cointop/config.toml`)

```toml
currency = "USD"

Keep in mind that some coin APIs, such as CoinMarketCap, update prices every 5 minutes so constant refreshes aren't necessary.

- Q: I'm getting the error `open /dev/tty: no such device or address`.

    -A: Usually this error occurs when cointop is running as a daemon or slave which means that there is no terminal allocated, so `/dev/tty` doesn't exist for that process. Try running it with the following environment variables:

    ```bash
    DEV_IN=/dev/stdout DEV_OUT=/dev/stdout cointop
    ```

- Q: I can only view the first page, why isn't the pagination is working?

  -A: Cointop uses ~15MB of memory so you can run it on a Raspberry Pi Zero if you wanted to (one reason why cointop was built using Go instead of Node.js or Python).

- Q: How does cointop differ from [rate.sx](https://rate.sx/)?
