Adoption of Best Practices and Continuous Integration in GitHub Repositories with Functional Languages
Abstract
Functional programming languages, such as Haskell, Elixir, and F#, have gained prominence in both academic and industrial contexts for enabling concise, composable, and parallelizable code. Although their adoption in open-source projects has increased, little is known about how well these projects follow established software engineering practices. This study investigates whether repositories written in functional languages adopt (i) maintenance guidelines recommended by the open-source community and (ii) continuous integration practices. An analysis of 496 GitHub repositories revealed widespread use of introductory documentation (91.9%) and licenses (89.7%), but low adoption of contribution guidelines (34.1%) and codes of conduct (17.7%). Continuous integration was present in 85.1% of the projects.
