Cangjie (programming language)

Cangjie is a high-level, statically typed, general-purpose, multi-paradigm programming language developed by Huawei, with compiled imperative and declarative styles. It was first released on June 21, 2024 through developer beta recruitment, for HarmonyOS NEXT app development. The name comes from a legendary figure of Chinese folklore credited with inventing Chinese characters. Development began in 2019 under Xinyu Feng, a professor at Nanjing University, with help from Tianjin University and Beihang University and later many Huawei engineers. Unlike ArkTS it is not derived from any existing programming language, though it uses modern programming language theory concepts, and it can run alongside ArkTS code in one program. It has built-in foreign function interface support for C and Python, macros for metaprogramming and an LLVM-based compiler. It supports app development on HarmonyOS, Linux, Windows, macOS, Android and iOS, and was open sourced on July 30, 2025.
