Leziscript (LZS)

An Esolang that can be Interpreted or Transpile to javascript code.

If you can't understand the documentation then figure it out on your own by reading the src code.

Example Code

Here's a code to print "Hello World!"

[[]][?][][[]][!?][].:[???]![[]][?][][[]][][[]].:[??]![?][[]][?][]..[??]![??][[]].>[[]][??!][].>[[]][][[]][][!?][[]].<<.>>>[!?][[]][?][][[]][].[??!]![][?][[]][?][].[??]![][[]][?][].>[[]][??][][[]].

Working Principle

• Similar to brainfck
• Binary form of ascii characters.
  • [] is 0 and [[]] is 1
  • Therefore, [[]][][[]][[]] is 1011
  • Similarly, H is 1001000 which is [[]][][][[]][][][]
• Switch/Change pointer using > or <
• Print the current character (the pointer positioned index) using .

Here is example for "Hi"

[[]][][][[]][][][].>[[]][[]][][[]][][][[]].

API

Here is the snippet to know how to use leziscript in node.js.

import { Interpreter, Transpiler } from "lzscript";
let code = "[[]][][][[]][][][].>[[]][[]][][[]][][][[]].";
console.log(Interpreter(code));
/*
{
  code: "[[]][][][[]][][][].>[[]][[]][][[]][][][[]].",
  options: {},
  output: "Hi",
  executionTime: 0.69,
  array: [1001000, 1101001]
}
*/

console.log(Transpiler(code))
/*
{
  code: 'let pointer = 0;\n' +
        'let array = [""];\n' +
        'let output = [];\n' +
        'array[pointer] += "1001000";\n' +
        'output.push(parseInt(array[pointer], 2));\n' +
        'pointer += 1;\n' +
        'if(array[pointer] === undefined) array[pointer] = "";\n' +
        'array[pointer] += "1101001";\n' +
        'output.push(parseInt(array[pointer], 2));\n' +
        'if(output.length) console.log(String.fromCharCode(...output));',
  options: {},
  executionTime: 0.69
}
*/

Here is the way to interpret or compile files together.

import { InterpretFiles, TranspileFiles } from "lzscript";
let file = "file.lzs";

console.log(InterpretFiles(file))
console.log(TranspileFiles(file))

Interpreter Options

| Name | Type | Description | | - | - | - | | doNotLog | boolean | Forcefully blocks . to print the output (default: false) |

Transpiler Options

| Name | Type | Description | | - | - | - | | minify | boolean | Minifies the output (default: false) | | beautify | boolean | Beatify the output (default: false) |

Advanced

Loops

Shorten your code using loops 🤓 ☝️

• The loop can do m for n number of times.
• Eg. [??!][[]]
  • here n is the value inside the first angled brackets (ie. ??!)
  • here m is the value after the first angled brackets (ie. [[]])
• n value is a string of ? or !
  • To parse n, ? is valued as 2 and ! as 1.
  • Eg. ??! becomes 2 + 2 + 1, which is 5
• Now, basically m will happen n times.
  • So [??!][[]] becomes to [[]] repeats 5
  • Resulting in [[]][[]][[]][[]][[]].
  • Outputing as 11111

Print All

Print all the values at once instead of print one by one.

• values gets printed when the code execution is over.
• Use Print All by prefixing the code with $
• Eg. $[???][[]]

Delete

Deletes a bit.

• Using !
• Eg. [[]][][[]]![][[]] is same as [[]][][][[]]
  • 101!01 is same as 1001

Copy and next

Copies the value and sets it to the next pointer.

• Using :
• Eg. [[]][]:[] is same as [[]][]>[[]][][]

Increament/Decrement

Increase/Decrease the value in the pointer by one.

• Using + or -
• Eg. [[]][][[]]+ is same as [[]][[]][]
  • 101+ is same as 110

Run Another File

Paste the code of someother file to the provided file.

• Using @(filename)
• Eg. @(helloWorld.tzs) or to get something from the dir where file is at @(#someOther.tzs) [# here is the dir name]

Encoders (for losers 💅)

You can ~cheat~ encode text to make it runnable code. Usage:

import { Encoder } from "lzscript";
let text = "I love to cheat!";
console.log(Encoder(text));
/*
{
 output: '[[]][][][[]][][][[]].>[[]][??!][].>[?][[]][][?][[]][][].>[?][[]][][??][[]].>[?!][[]][][?][[]][].>[?][[]][][][[]][][[]].>[[]][??!][].>[?!][[]][][[]][][].>[?][[]][][??][[]].>[[]][??!][].>[?][[]][?!][][?][[]].>[?][[]][][[]][?!][].>[?][[]][][][[]][][[]].>[?][[]][??][][[]].>[?!][[]][][[]][][].>[[]][??][][[]].',
}
*/

You can use different encoding styles. (idktoexplainthestyles) | Name | Description | | - | - | | Normal | Makes the encoder go to each character and encode it and prints it (default, shown in above usage) | | Printer | List all the characters at the start and then just changing the pointer and printing | | OneSlot | Just uses one pointer value | Usage:

import { Encoder, EncodeStyle } from "lzscript";
console.log(Encoder("Some Text", EncodeStyle.Printer))
