Explore the inner workings of Language Servers through hands-on development using Haskell in this 22-minute conference talk from Lambda Days 2025. Demystify these essential programming tools that developers use daily but often take for granted due to their seamless plug-and-play functionality. Learn why Language Servers, despite appearing as complex "magic black boxes," are actually straightforward pieces of software that can be understood and built with relative ease. Discover how functional programming languages, particularly Haskell, serve as nearly ideal candidates for Language Server development. Gain practical insights into the architecture and implementation details that make these ubiquitous development tools work, transforming your understanding from user to potential creator of these fundamental programming utilities.
