# linespin

Simple progress output

Extracted from [music.json](https://github.com/geekjuice/musicjson)


## Why?

It's nice to know that your program is running and not dead with a simple
spinner animation


## Usage

```sh
  $ npm install linespin
```

```javascript
  // linespin_example.js

  var Linespin = require('./linespin');

  // Create new instance of linespin
  var linespin = new Linespin('Spinning...', 'All done!', 100);

  // Start spinner at beginning of task
  linespin.start();


  // Some long running task...
  linespin.error('Error!');

  // Continuing process...
  linespin.warn('Warning!');

  // Say something...
  linespin.msg('Hello world!');

  // Results down the line...
  var results = 42;

  // Stop at the end of task and overwrite message with results
  linespin.stop('The answer is ' + results);
```


```sh
  $ node linespin_example.js
    [/] Spinning...

  # During process...

  $ node linespin_example.js
    [!] Error!          # Red
    [!] Warning!        # Yellow
    [•] Hello world!    # White
    [-] Spinning...     # Yellow/Blue

  # On finish

  $ node linespin_example.js
    [!] Error!            # Red
    [!] Warning!          # Yellow
    [•] Hello world!      # White
    [✓] The answer is 42  # Green/Blue
```


## Notes
* Assumes your progress does not print to console/stdout as the spinner works by
  replacing the same line over and over again to produce the _animation_
* Add editable color and symbol options
* Add replace text method to replace current text i.e. Progress done
* ~~Aggregate message output methods (wet code...)~~
* ~~Overwrite console.log or provide similar function i.e. @message~~
* ~~Need to add Gruntfile~~
