A very simple C based language written in C++
A small hobby project written in ~10 days
The language is purely interpreted and parsed with an LALR(1) parser
Run any file by running the .exe with the file name as an argument
In Windows PowerShell:
./Pengo.exe fileName.pgo
You can also add a -d at the end to show the parse tree of the file
./Pengo.exe fileName.pgo -d
- Math order of operations evaluation
- Variables
- Functions
- Built in language functions
- If, Elif, and Else conditional statements
- While loops
- Scoping
println("Hello World!");
Output:
Hello World!
print("Enter a number: ");
number = int(input());
println("You entered "+number+"!");
Output:
Enter a number: 3
You entered 3!
func add(left, right)
{
return left + right;
}
println("3 + 4 = "+add(3,4));
Output:
3 + 4 = 7
counter = 0;
while(counter <= 10)
{
println(counter);
counter = counter + 1;
}
Output:
0
1
2
3
4
5
6
7
8
9
10
println("What is the password?");
in = input();
if(in == "123")
println("Access Granted!");
else
println("Access Denied!");
Output:
What is the password?
123
Access Granted!
// Sets variable equal to a built in function
p = println;
p("This prints!");
func math(operation)
{
func add(left, right)
{
return left + right;
}
func subtract(left, right)
{
return left - right;
}
if(operation == "add")
return add;
elif(operation == "subtract")
return subtract;
}
result = math("add")(4, 2);
println("Result is "+result);
result = math("subtract")(4, 2);
println("Result is "+result);
Output:
This prints!
Result is 6
Result is 2
