StringBuilder

An string builder for Node.js

npm install

npm install stringbuilder

Usage

var StringBuilder = require('stringbuilder')

// create an StringBuilder();
var sb = new StringBuilder( {newline:'\r\n'} );
var sbInside = new StringBuilder( {newline:'\r\n'} );
  
// you can configure all new intances of the StringBuilder
// as default win32='\r\n' others='\n'
// StringBuilder.configure({newline:'\r\n'});

sb.append('some text') // append text
sb.append('{0:YYYY}', new Date()) // append text formatted
sb.appendLine('some text') // append a new line
sb.appendLine('{0:$ 0.1}', 50.1044) // append a new line formatted
ab.append( sbInside );  // append other StringBuilder into sb
                        // you can append text into `sbInside` after that                        

sbInside.append('another text');

extends the String

var StringBuilder = require('stringbuilder')

StringBuilder.extend('string');

'The current year is {0:YYYY}'.format(new Date(2013)); // The current year is 2013
or the same
String.format('The current year is {0:YYYY}', new Date(2013)); // The current year is 2013

example

var StringBuilder = require('stringbuilder')
  , fs = require('fs');

// Make an markdown file of the beatles
var data = {
    band: "The Beatles"
  , formed: new Date(1960)
  , discography: [
      { name: 'Sentimental Journey', created: new Date(1970), price: (Math.random()*10)+1 }
    , { name: 'Beaucoups of Blues', created: new Date(1970), price: (Math.random()*10)+1 }
    , { name: 'Ringo', created: new Date(1973), price: (Math.random()*10)+1 }

    , { name: 'Ringo the 4th', created: new Date(1977), price: (Math.random()*10)+1 }
  ]
};

var main = new StringBuilder()
  , discography = new StringBuilder();

// extend de String object
StringBuilder.extend('string');

var filename = './{0}.md'.format(data.band);

var stream = fs.createWriteStream( filename );

  .appendLine()
  .appendLine('### Discography')
  .appendLine()
  .append(discography) // append an StringBuilder
  .appendLine()

  .appendLine('Elvis Presley, Carl Perkins, Little Richard and Chuck Berry ...')
  .appendLine()
  .appendLine('### Genres')  
  .appendLine('')

  .append('rock and roll, and their repertoire ultimately expanded to include')
  .appendLine('a broad variety of pop music ...')
  .insert('## ', 0) // Insert text
  ;

// append into the discography stringbuilder
data.discography.forEach(function(disk){
  discography.appendLine(' - {0} in {1:YYYY}   *{2:$ 0,0.00 } release price*', disk.name, disk.created, disk.price);
});

var filename = './{0}.md'.format(data.band);
var stream = fs.createWriteStream( filename, 'utf-8' );

main.pipe(stream);
main.flush();

build html

NOTE: The idea of this example is show you how create parts of one output string separately and then combine all of them, if you need makes html can use a template engine like handlebars, this is only an example

var html = new StringBuilder()
  , head = new StringBuilder({ newline: '\r\n\t' }) // add a tab at the end
  , body = new StringBuilder({ newline: '\r\n\t' }) // add a tab at the end
  ;

var initTag, endTag, tag, attr, lorem;

initTag = '<{0}>';
endTag = '</{0}>';
tag = '{0}{{1}}{1}'.format(initTag, endTag);
attr = '{0}="{1}"';
lorem = 'Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.';

// make the body
body.append('\t')
  .appendLine(tag.format('h1', 'StringBuilder example'))
  .append(tag.format('p', lorem));

// make the head
head.append('\t')
  .appendLine('<meta {0}>', attr.format('charset', 'UTF-8'))
  .appendLine('<meta {0} {1}>', attr.format('http-equiv', 'X-UA-Compatible'), attr.format('content', 'IE=edge'))
  .append(tag.format('title', 'Generate html with StringBuilder'));

// make the html
html.appendLine('<!doctype html>')
  .appendLine('<html {0}>', attr.format('lang', 'en'))

  // head
  .appendLine(initTag.format('head'))
  .append(head)
  .appendLine()
  .appendLine(endTag.format('head'))

  // body
  .appendLine(initTag.format('body'))
  .append(body)
  .appendLine()
  .appendLine(endTag.format('body'))

  .append(endTag.format('html'));

output

<!doctype html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <title>Generate html with StringBuilder</title>
</head>
<body>
  <h1>StringBuilder example</h1>
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
</body>
</html>

formats

To apply formats please see moment and numeral

var sb = new StringBuilder();

sb.append('{0:format}');

dates examples

sb.append('{0:L}', new date());      // 04/29/2013
sb.append('{0:LL}', new date());     // April 29 2013
sb.append('{0:LLL}', new date());    // April 29 2013 9:13 AM
sb.append('{0:LLLL}', new date());   // Monday, April 29 2013 9:13 AM

numbers examples

sb.append('{0:$0,0.00}', 1000.234);   // $0,000.23
sb.append('{0:0%}', 1);               // 100%
sb.append('{0:0b}', 100);             // 100B
sb.append('{0:(0,0.0000)}', -10000);  // (10,000.0000)

Please see async

This is the way that the StringBuilder makes the output string.
