Mallu Script

Malluscript is an esoteric scripting language based on manglish and malayalam memes. The language uses trending Malayalam memetic words as keywords. The language is not strictly type-safe and uses only two datatypes strings and integers. Currently, malluscript is on the development phase and undergoing vigorous changes. Always check the release section for pre-built binaries for the interpreter.

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

  dhe_pidicho "hello world";
  dhe_pidicho variable;
  dhe_pidicho "Onnum randum kottiyal " + 1+2 + " aane"; 

  • Alternate Keywords
    • ദേ_പിടിച്ചോ

• In order to get keyboard input from the user

  For integer inputs

  variable = number_thada;
  

  • Alternate Keywords
    • നമ്പർ_താടാ

  For string inputs

  variable = address_thada;
  

  • Alternate Keywords
    • അഡ്രസ്_താടാ

Datatypes and Storage

Malluscript is not strictly type-safe.The language, currently, supports only integers and string literals as datatypes.

In order to declare a variable

pwoli_sadhanam variable_name

• Alternate Keywords
  • pwoli_sanam
  • pwoli_saanam
  • poli_sadhanam
  • poli_sanam
  • poli_saanam
  • പൊളിസാധനം

To assign it some value

variable_name = 1;
second_var = "ente string";

Conditional Statements And Expressions

The conditional expression has the following syntax

seriyano i um 0 um same_aane {

} seri_allel {

}

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

In general

• i um 0 um same_aane checks if i is equals to 0

• i um 0 um same_alle checks if i not equals to 0

• i nekal 0 cheruthane checks if 0 is less than i

• i nekal 0 veluthane checks if 0 is greater than i

  • Alternate Keywords
    • seriyano
      • seriyano_mwone
      • seriyano
      • ശെരിയാണോ_മോനെ
    • cheruthane
      • cheruthanenkil
      • cheruthanekil
      • charuthane
      • charuthanenkil
      • charuthanekil
      • ചെറുതാണെകിൽ
      • ചെറുതാണെങ്കിൽ
    • same_aane
      • സെയിം_ആണേ
    • um
      • ഉം
    • ne_kal
      • നെകാൾ
    • veluthane
      • veluthanenkil
      • veluthanekil
      • valuthanenkil
      • valuthanekil
      • valuthane
      • വലുതാണെ
      • വലുതാണെങ്കിൽ
      • വലുതാണെകിൽ
    • cheruthane
      • cheruthane
      • cheruthanenkil
      • cheruthanekil
      • charuthane
      • charuthanenkil
      • charuthanekil
      • ചെറുതാണെകിൽ
      • ചെറുതാണെങ്കിൽ

Iterative Statements Or Loops

The loops in malluscript look as follows

repeat_adi 0 nekal i veluthane {
  i = i-1;
}

• Alternative Keywords
  • റിപീറ്റടി

Functions

The functions definition in malluscript are defined as follows.

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

The functions can also return values.

factorial(n) {
    seriyano n um 0 um same_aane {
        koduthek 1;   
    }
    koduthek n * factorial<n-1>;
}

• Alterative keywords for koduthek
  • കൊടുത്തേക്
  • കൊടുത്തെക്

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

pwoli_sadhanam num;
pwoli_sadhanam factorial;
dhe_pidicho "Input number:";
num = number_thada;
factorial = 1;

repeat_adi 0 um num um same_alle {
    factorial = factorial * num;
    num = num -1;
}

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

Same in pure Malayalam would be

പൊളിസാധനം നമ്പർ;
പൊളിസാധനം ഫാക്ടോറിയൽ;
ദേ_പിടിച്ചോ "ദയവായി നമ്പർ തരുക: ";
നമ്പർ = number_thada;
ഫാക്ടോറിയൽ = 1;

റിപീറ്റടി 0 ഉം നമ്പർ ഉം സെയിം_അല്ല {
    ഫാക്ടോറിയൽ = ഫാക്ടോറിയൽ * നമ്പർ;
    നമ്പർ = നമ്പർ -1;
}

ദേ_പിടിച്ചോ "ഫാക്ടോറിയൽ : " + ഫാക്ടോറിയൽ + "\n";

Notes

The language as mentioned above is under the development phase and its structure can change overnight, suddenly. This language is not meant to disrespect anyone and wrote just for fun.

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 :)
