Architecture description languages (ADLs) should consider both structural and runtime perspectives of software architectures, an important requirement for current software systems. However, most existing ADLs are disconnected from the runtime level, thus entailing architectural mismatches and inconsistencies between architecture and implementation. With the emergence of the new generation programming languages for large-scale, dynamic, and distributed systems, this problem becomes worse since most existing ADLs do not capture the features of this type of language. In this context, we investigate the generation of source code in the Go programming language from architecture descriptions in the π-ADL language as they are both based on the π-calculus process algebra. We define the correspondences between π-ADL and Go elements and present how architecture descriptions in π-ADL can be automatically translated to their respective implementations in Go through a real-world flood monitoring system.
