![test](https://github.com/sporto/gleam_string_builder/workflows/test/badge.svg)

A Gleam library for building strings

```rust

let formatter =

  sb.new

  |> sb.string("The winner is ")

  |> sb.arg_string

  |> sb.string(" with ")

  |> sb.arg_int

  |> sb.string(" points!!")

  |> sb.end2

formatter("Sam", 12)

==

"The winner is Sam with 12 points!!"

```

## Custom formatter

A custom formatter is a function that takes a callback and then returns another function that calls that callback with a string.

```rust

fn custom_formatter(callback) {

  fn(state: State) {

    let str = state_to_string(state)

    callback(str)

  }

}

```

Then you can add this custom formatter to a pipeline using `compose`.

```rust

import string_builder as sb

let formatter =

  sb.new

  |> sb.string("The current state is ")

  |> sb.compose(custom_formatter)

  |> sb.string("!")

  |> sb.end1

formatter(Done)

```

## Installation

This package can be installed by adding `gleam_string_builder` to your `rebar.config` dependencies:
