Wolf – A general purpose scripting language

A scripting language that is strongly typed and dynamic language with a simple and well-known syntax, implementing basic compiler techniques that can be used as a reference to teach students or helps enthusiastic programmers to know how backend implementation of a programming language works. The main aim of this language is to provide all the essential features that a modern programming language offers while keeping the code is as minimal as possible.It's also extendable through its Java-Wolf APIs.

Examples

Factioral of a num:

#declaring function
func fact(n){
	if n<=1 {
		return 1
	}
	return n*fact(n-1)
}

# Getting input from user
n = integer(input())

#Calling and printing fact function
print(fact(n))

QuickSort:

func quickSort(a,l,r){
	if l>=r {return ;}
	
	pIndex, i, piv = l, l, r
	
	while i<r{
		if a[piv] > a[i]{
			a[i], a[pIndex] = a[pIndex], a[i]
			pIndex = pIndex + 1
		}
		i = i+1
	}
	a[pIndex], a[piv] = a[piv], a[pIndex]
	quickSort(a, l, pIndex-1)
	quickSort(a, pIndex+1, r)
}

a = [7, 5, 3, 13, 56, 4, 27, 8, 29, 45]
quickSort(a, 0, a.length()-1)

print(a)

KMP(pattern matching algorithm):

func kmpAlgo(text, pattern){
	M, N = len(text), len(pattern)
	lps = [0]
	i, length = 1, 0
	N = len(pattern)
	
	while i < N{
		if pattern[i] == pattern[length] {
			lps.append(length+1)
			i , length = i + 1, length + 1
		}elif length != 0 {
			length = lps[i-1]
		}else{
			lps.append(0)
			i = i+1
		}
	}
	i, length = 0, 0
	while i < M{
		if text[i] == pattern[length] {
			i , length = i + 1, length + 1
		}elif length != 0 {
			length = lps[i-1]
		}else{
			i = i+1
		}
		if length == N {
			return i-length
		}	
	}
}

text = input("Enter text: ")
pattern = input("Enter pattern to search: ")
index = kmpAlgo(text, pattern)

print("Text: ",text)
print("Pattern: ", pattern)
print("Pattern found at : ", index)
