strinc v1.0.1

strinc

Incremental string generator

Simple example

var Strinc = require('strinc');
var generate = Strinc();

for (var i = 0; i < 10; i++)
  console.log(generate());

Will output:

a
b
c
d
e
f
g
h
i
j

Without arguments Strinc will create a generator function using standard english alphabet letters.

Advanced example

You can give your own alphabet to Strinc:

var Strinc = require('strinc');
var generate = Strinc('01');

for (var i = 0; i < 10; i++)
  console.log(generate());

Will output:

0
1
10
11
100
101
110
111
1000
1001

In this example we gave "01" as the alphabet. In this case generator generates binary number strings.

Predefined alphabets

Strinc has some predefined alphabets for your convinience:

Strinc.STR = english alphabet (low and high cap letters)
Strinc.BIN - binary numbers
String.DEC - decimal numbers
Strinc.OCT - octal numbers
Strinc.HEX - hexadecimal numbers

So if you want to generate hexadecimal number strings, do:

var Strinc = require('strinc');
var generate = Strinc(Strinc.HEX);

for (var i = 0; i < 20; i++)
  console.log(generate());

Will output:

0
1
2
3
4
5
6
7
8
9
a
b
c
d
e
f
10
11
12
13

Continuing from an existing string

If you already have a string from which you want to continue id generation you can do it using Strinc.parse() function.

Example: YOu have a hexadecimal id a4c6 from which you want to continue id generation.

var Strinc = require('strinc');
var generate = Strinc.parse("a4c6", Strinc.HEX);

for (var i = 0; i < 10; i++)
  console.log(generate());

Will output:

a4c6
a4c7
a4c8
a4c9
a4ca
a4cb
a4cc
a4cd
a4ce
a4cf
