Avocado programming language
Avocado Polish programming language
The Avocado language is compiled and currently allows for the creation of console applications. Work on Avocado and the integrated development environment (IDE) began on February 19, 2025. A unique feature of this language is the ability to write commands in Polish and English, compiling code into .exe format. The language is freely available for commercial and non-commercial projects. The Avocado source code is available under the MIT License on GitHub. Avocado is transpiled to Free Pascal and then compiled by the FPC compiler, making it as fast as C or Rust, but with syntax reminiscent of Python. The Avocado IDE interface has been translated into 6 languages Official website: https://avocado-code.com/ Documentation: https://doc.avocado-code.com/ Source code https://github.com/Programista-Art/Avocado 🥑 Hey! If you like my programming language Avocado, support the project on Patronite 👉 https://patronite.pl/programista-art Every bit of support means a lot. -
