Welcome to the official wiki of the Piège programming language!

About

Piège /ˈpɪ.eʒ/ is an interpreted language used to compute various sorts of mathematical operations, ranging from basic arithmetics to matrix operations. Piège files have the .piege file extension.

To run Piège code, you can use the official Python interpreter, Piègeur, found in this repository.
