MPSL: Multi-Purpose Scripting Language

A dynamically typed, high-level programming language designed for use as a scripting language.

Example Code

fn @fib n {
    if n <= 1 => n
    else => @fib n - 1! + @fib n - 2
}

fn @get_ordinal num {
    match @mod num, 100 {
        @ = 11 | @ = 12 | @ = 13 => "th"
        else => match @mod num, 10 {
            @ = 1 => "st"
            @ = 2 => "nd"
            @ = 3 => "rd"
            else => "th"
        }
    } -> var suffix

    @"{num}{suffix}"
}

# Calculate 20 numbers in the Fibonacci sequence
each i : @range_to 20 {
    @print @"{@get_ordinal i + 1}: {@fib i}"
}

Using Standalone

Clone this repository and build the source code for the latest version, or download the interpreter executable from the releases section. Run the executable from the command line and pass in the path to the MPSL file you would like to run.

Running Tests

If using Visual Studio, you can use Test Explorer. Otherwise, run dotnet test from the command line.
