Dala is an attempt at an interpreted functional language where there are no variables, only single-parameter functions.
The current implementation is still in very early stages: it only supports integer values and very basic flow.
The language grammar uses F#'s FsLex and FsYacc, the interpreter is written in F#, and the REPL is in C#.
Statements in the REPL console are evaluated after a semicolon is entered, the language itself has no semicolons yet.
Below is a simple example of a function that adds two numbers:
The function add takes one parameter and returns another function, addToN, which also takes a single parameter and adds it to the parameter of add. So, calling add(3), for example, returns a function that takes a nunmber and adds it to 3 and returns the result; so calling add(3)(4) passes 4 to the function returned from add(3) and returns 7.
Signle condition if-statements and recursion are also supported, as shown in the example below with a factorial function:
