ml@gentoo.org ML sci-mathematics@gentoo.org Gentoo Mathematics Project ELPI implements a variant of λProlog enriched with Constraint Handling Rules, a programming language well suited to manipulate syntax trees with binders. ELPI is designed to be embedded into larger applications written in OCaml as an extension language. It comes with an API to drive the interpreter and with an FFI for defining built-in predicates and data types, as well as quotations and similar goodies that are handy to adapt the language to the host application. https://raw.githubusercontent.com/LPCIC/elpi/master/CHANGES.md https://github.com/LPCIC/elpi/issues/ LPCIC/elpi
