devlang

Description

Welcome to our self-made compiler project! This compiler is developed using Prolog, Java, and Shell Script, designed to work seamlessly across MacOS, Windows, and Linux platforms. Our project walks you through the process of compiling and executing custom code effortlessly.

Usage

./devlang [path/to/code]

Example Code

Hello World

dev
{
    tout(charr("Hello world!")) 
}
lang

Arithematic Expression

dev{
    var x = int(7) ,
    var y = int(8) ,

    tout([ x + y]) ,
    tout([ x - y]) ,
    tout([ x * y]) ,
    tout([ x / y]) 
}lang

Boolean Expression Usage

dev{
    tout(and(bool(true) , bool(false))) ,
    tout(and(bool(true) , bool(true))) ,

    tout(or(bool(false) ,  bool(false))) ,
    tout(or(bool(true) , bool(false))) ,

    tout(not(bool(true))) ,
    tout(not(bool(false))) ,

    tout(int(5)>int(3)) ,
    tout(int(5)==int(5)) ,
    tout(int(5)<int(3)) 
}lang

Assignment Statements

dev
{
    var string = charr("hello") ,
    var b = bool(true) ,
   
    var x = [ int(5) + int(6) ] ,
    var x = [ int(5) - x ] ,
    
    
    tout( x ) ,
    tout ( b ) ,
    tout( string ) ,
    tout( charr("true") ) 

}
lang

Build Compiler Locally

Build Lexer (Java)

cd src/Lexer
javac -cp classes/antlr-runtime-4.13.1.jar CustomLanguageLexer.java
javac -cp "classes/antlr-runtime-4.13.1.jar:." Main.java
java -cp "classes/antlr-runtime-4.13.1.jar:." Main

Generate Parse Tree, And Execute

swipl -s src/parser/Parser.pl -g "procedure(T,[Tokens],R), write(T),halt."
swipl -s src/interpreter.pl -g "eval_procedure([Parsed Tree], R),halt."
