Avocado język programowania
Avocado Polski język programowania
Język Avocado jest kompilowany i aktualnie pozwala na tworzenie aplikacji konsolowych. Prace nad Avocado oraz zintegrowanym środowiskiem programistycznym (IDE) rozpoczęły się 19 lutego 2025 roku. Unikalną cechą tego języka jest możliwość pisania komend w języku polskim oraz kompilacja kodu do formatu .exe. Język jest dostępny bezpłatnie dla projektów komercyjnych i niekomercyjnych. Zrealizowano 138 funkcji! Avocado jest transpilowany do Free Pascala, a następnie kompilowany przez kompilator FPC, co czyni go tak szybkim jak C lub Rust, ale ze składnią przypominającą Pythona.
