`colourista` is the library that provides a convenient interface for printing
colourful messages to the terminal. It is based on
[`ansi-terminal`](https://hackage.haskell.org/package/ansi-terminal), however,
in contradistinction to this Haskell library, `colourista` is a high-level
wrapper focused on easily achieved output modification without low-level setup.

## Interface

The two main functions that `colourista` provides are:

* `formatWith` β€” the function that formats pure output by applying provided
formatting codes. It works with polymorphic strings.
* `formattedMessage` β€” the function that outputs the formatted output directly
into the terminal (working in `IO` with `Text`).

The library also provides a set of different pure and impure helpers for the
colouring and emphasis.

## Example

## How to use

`colourista` is compatible with the latest GHC compiler versions starting from `8.4`.

In order to start using `colourista` in your project, you will need to set it up with the three easy steps:

1. Add the dependency on `colourista` in your project's `.cabal` file. For this,
you should modify the `build-depends` section by adding the name of this
library. After the adjustment, this section could look like this:

```haskell
build-depends: colourista ^>= LATEST_VERSION
, ...
```
2. In the module where you wish to use the colourful output with `colourista`,
you should add the import:

```haskell
import Colourista (...)
```
3. Now you can use the functions from the library. For example:

```haskell
import qualified Data.Text as Text

main :: IO ()
main = successMessage $ Text.pack "All set up!"
```
### Usage with Stack

If `colourista` is not available on your current Stackage resolver yet, fear not! You can still use
it from Hackage by adding the following to the `extra-deps` section of your `stack.yaml`
file:

```yaml
extra-deps:
- colourista-0.1.0.0
- ...
```

Then you can add it as a dependency in your `package.yaml` file as usual:

```yaml
library:
dependencies:
- colourista
```

Great!
