GNU Guile

Common card · No. 449891

GNU Ubiquitous Intelligent Language for Extensions (GNU Guile) is the preferred extension language system for the GNU Project and features an implementation of the programming language Scheme. Its first version was released in 1993. In addition to large parts of Scheme standards, Guile Scheme includes modularized extensions for many different programming tasks. For extending programs, Guile offers libguile which allows the language to be embedded in other programs, and integrated closely through the C language application programming interface (API); similarly, new data types and subroutines defined through the C API can be made available as extensions to Guile. Guile is used in many programs under the GNU project umbrella (GDB, Make, Guix, GNU TeXmacs, GnuCash, LilyPond...) but it also sees use outside of that, for example in Google's schism and Lepton-EDA.
