Malluscript

Malluscript is an esoteric scripting language that allows one to write computer programs in Malayalam. The concept of Malluscript stems from the idea of promoting inclusivity and linguistic diversity within the world of coding. By enabling programmers to express their ideas and algorithms in Malayalam, Malluscript serves as a bridge between traditional programming languages and the rich linguistic heritage of the Malayalam-speaking community. Currently, Malluscript is on the development phase and undergoing vigorous changes. Always check the release section for pre-built binaries for the interpreter.

Note: For support please join our Discord.

Installation

Either download precompiled binaries from release page or clone this repository

git clone https://github.com/sreyas-sreelal/malluscript.git

Building

The interpreter can be compiled as follows

cd malluscript
cargo build --release

Note: You require Rust compiler installed on your machine in order to compile the interpreter

Executing malluscript programs

Malluscript can be used in two ways

Interactive shell

To start the interactive shell, just run following in the terminal

./malluscript

Something like this would come

Mallu Script Version 0.1.0
>> 

Here you can start writing your malluscript codes on the way!

Run malluscript program files

Write the code in the file with .ms extension and execute it as follows

./malluscript file_name.ms

Language Syntax And Grammar

Basic arithmetic operations can be done using +,-,*,/,% (modulo). Every expression ends with ;. { and } introduces a new block like c like languages. Every keyword has alternate ones too, each with different dialects and also in Malayalam unicodes.

Basic I/O operations

• Printing or writing to console is done as follows

  ezhuthuga "hello world";
  ezhuthuga variable;
  ezhuthuga "Onnum randum kottiyal " + 1+2 + " aanu"; 

  • Alternate Keywords
    • ezhuthuka
    • ezhuthuga
    • kanikuka
    • kanikuga
    • എഴുതുക
    • കാണിക്കുക

• In order to get keyboard input from the user

  For integer inputs

  variable = akam_vangikuga;
  

  • Alternate Keywords
    • akam_vangikuga
    • akkam_vangikuga
    • അക്കംവാങ്ങിക്കുക

  For string inputs

  variable = vachakam_vangikuga;
  

  • Alternate Keywords
    • vachakam_vangikuga
    • vachakam_vangikuka
    • vachagam_vangikuga
    • vachagam_vangikuka
    • വാചകംവാങ്ങിക്കുക

Datatypes and Storage

Malluscript is not strictly type-safe.The language supports integer,float and string literals as primary datatypes and it also support compound datatype called List.

To assign it some value and declare a variable

variable_name = 1;
second_var = "ente string";

Lists in Malluscript are similar to compound types in other mainstream programming languages. A list can have different type of primary data in it. An example usage of List would be:

x = [1,4,5,6,"malluscript"];
x = x + "more data";
i = 0;
i um 6 um onnallenkil avarthikuga {
    ezhuthuga x[i] + " ";
    i = i+1;
}

Using + operator along side a list data, will append the other operand into that list. List data can be accessed using subscript operators []. Also unlike other datatypes when passed as an argument to a function, it will be passed as reference instead of passed as value.

Conditional Statements And Expressions

The conditional expression has the following syntax

i um 0 um thullyaman enkil {

} adhallengil {

}

The above snippet checks whether i equal to 0 and if yes the code in the first block will execute otherwise block defined by adhallengil will get executed.

In general

• i um 0 um thullyaman enkil checks if i is equals to 0

• i um 0 um thullyamalla enkil checks if i not equals to 0

• i nekal 0 cheruthan enkil checks if 0 is less than i

• i nekal 0 veluthan enkil checks if 0 is greater than i

  • Alternate Keywords
    • enkil
      • engil
      • എങ്കിൽ
    • thullyamalla
      • onnalla
      • തുല്യമല്ല
      • ഒന്നല്ല
    • thullyaman
      • onnan
      • തുല്യമാണ്
      • ഒന്നാണ്
    • um
      • ഉം
    • ne_kal
      • നെകാൾ
    • veluthan
      • വലുതാണ്
    • cheruthan
      • ചെറുതാണ്
    • adhallengil
      • adhallenkil
      • അതല്ലെങ്കിൽ

Agglutination of conditional statements

Conditional statements like thullyaman enkil can be agglutinated together like thullyamanenkil

Iterative Statements Or Loops

The loops in malluscript look as follows

0 nekal i veluthan enkil avarthikuga {
  i = i-1;
}

• Alternative Keywords
  • aavarthikuga
  • avarthikuga
  • aavarthikuka
  • avarthikuka
  • ആവർത്തിക്കുക

Functions

The functions definition in malluscript are defined as follows.

ente_function(variable1,variable2) {
  ezhuthuga variable1 + variable2;
}

The functions can also return values.

factorial(n) {
    n um 0 um thullyaman enkil {
        kodukuga 1;   
    }
    kodukuga n * factorial<n-1>;
}

• Alterative keywords for kodukuga
  • kodukuka
  • madakiayakuga
  • madakiayakuka
  • കൊടുക്കുക
  • മടക്കിഅയയ്ക്കുക

To call a function function name followed by angle brackets are used.

my_function<arg1,arg2>;

Example

A simple program to find factorial in malluscript would be

kanikuga "Input number:";
num = akam_vangikuga;
factorial = 1;

0 um num um thullyamalla enkil avarthikuga {
    factorial = factorial * num;
    num = num -1;
}

kanikuga "Factoral is : " + factorial + "\n";

Same in pure Malayalam would be

എഴുതുക "ദയവായി നമ്പർ തരുക: ";
നമ്പർ = അക്കംവാങ്ങിക്കുക;
ഫാക്ടോറിയൽ = 1;

0 ഉം നമ്പർ ഉം തുല്യമല്ല എങ്കിൽ {
  ഫാക്ടോറിയൽ = ഫാക്ടോറിയൽ * നമ്പർ;
  നമ്പർ = നമ്പർ -1;
}

എഴുതുക "ഫാക്ടോറിയൽ : " + ഫാക്ടോറിയൽ + "\n";

Notes

The language as mentioned above is under the development phase and its structure can change overnight, suddenly.

Any kind of contribution is always welcome. If you have any ideas or improvements to provide for this project open a pull request or if you have any difficulties using this language open an issue :)
