Pyramidion

An esoteric language where everything is structured as a pyramid.

What is this language?

Pyramidion uses pyramids to structure code, evaluating expressions from the base up to the peak. Operators at higher levels share results from lower levels, requiring careful planning of the pyramid’s structure.

Inspired by Kaleidoscope and developed to explore LLVM and compiler optimization.

Example Syntax

      +
     + +
    * 0 *
   x x y y
pyramid bar(x, y)

 bar
 + +
1 1 2

• The function bar(x, y) squares two numbers and then adds them.
• The main pyramid calls bar(1 + 1, 1 + 2).

Commands

Name	Arity	Function
+	2	a + b
-	2	a - b
*	2	a * b
/	2	a / b
pyramid	N/A	Function definition

Usage

To compile Pyramidion using clang++ and LLVM, run:

cd src/
clang++ -g pyramidion.cpp `llvm-config --cxxflags --ldflags --system-libs --libs core orcjit native` -O3 -o pyramidion

To execute a Pyramidion program:

./pyramidion <input file>
