Javascript easy string manipulation, file access, and json parsing. by @sha0coder

require('protos.js');



var users = [];

users.load('users.txt');  // arrays can load data

if (!users.has('Peter')) { // arrays can check content
    users.push('Peter')
    users.save('users.txt') // arrays can save data
}

if ('Peter'.in(users)) {   // strings can also check if exists in arrays
    'Peter is here'.log(); // strings can console.log
    'some error'.err();   // same as console.error()
    'John'.appendFile('users.txt') // strings can append to file
}

var str = 'test';
str.log(); // same as console.log(str);
str.save('file.txt');
str.save('file.txt', function() {
   'async saved!'.log(); 
});

var str = ''.load('data.txt');

['a','b','c','d'].cut(1,3);
['a','b','c','d'].cut(1,-1); // -1 means last item (like python)

// STRING MANIPULATION MADE EASY (python style)
var el = 'hello'.cut(1,3); 
var lo = 'hello'.cut(3,-1); 

> 'hello'.cut(0,4).log();
'hell'

> '3'.toInt();
3




// JSON FILES
 
var struct = {}.load('file.json');  // load json files into js object
struct.save('file.json');           // save js object into json file
struct.save('file.json', function() { // save async
   'saved'.log(); 
});
struct.dir()  // same as console.dir(struct);


// FUZZY HASHING thanks to ctph.js

'hello'.compare('hell')     // 50%
'hello'.compare('hello')    // 100%
'hello'.compare('abcd')     // 0%

var hash = 'hello'.fuzzyHash();

// calling a function on all items
objects.call('method',[params]);



// ARRAY USEFUL METHODS

> ['cats','dogs','birds'].choice()
'dogs'

> [3, 1, 2, 3].unique()
[ 3, 1, 2 ]


// SHELL EXECUTION

'ls'.exec(function(stdout,stderr) {
    stdout.log();
    stderr.err();
});

// STATISTICS


> [1,3,2].max()
3

> [1,3,2].min()
1

> [1,3,2].average()
2

> var n = [];
> n.fillNums(1,10);
> n.cut(0,1)
[ 1 ]

> n.cut(-3,-1) // -1 means last item
[ 9, 10 ]


// INTROSPECT

> var a = {b:1};
> a.dir();
{ b: 1 }

> var a = [1,2,3];
> a.dir();
[ 1, 2, 3 ]


// ASCII  chr() 

> (0x41).chr();
'A'

> 'HELLO'.chr();
[ 72, 69, 76, 76, 79 ]

> [72,69,76,76,79].chr()
'HELLO'



// ITERATION knowing the index

['dog','cat','bird'].each(function(i,pet) {
   pet.log(); 
});
