synopsis: "ELPI - Embeddable λProlog Interpreter"
33
+
description: """
34
+
ELPI implements a variant of λProlog enriched with Constraint Handling Rules,
35
+
a programming language well suited to manipulate syntax trees with binders.
36
+
37
+
ELPI is designed to be embedded into larger applications written in OCaml as
38
+
an extension language. It comes with an API to drive the interpreter and
39
+
with an FFI for defining built-in predicates and data types, as well as
40
+
quotations and similar goodies that are handy to adapt the language to the host
41
+
application.
42
+
43
+
This package provides both a command line interpreter (elpi) and a library to
44
+
be linked in other applications (eg by passing -package elpi to ocamlfind).
45
+
46
+
The ELPI programming language has the following features:
47
+
48
+
- Native support for variable binding and substitution, via an Higher Order
49
+
Abstract Syntax (HOAS) embedding of the object language. The programmer
50
+
does not need to care about technical devices to handle bound variables,
51
+
like De Bruijn indices.
52
+
53
+
- Native support for hypothetical context. When moving under a binder one can
54
+
attach to the bound variable extra information that is collected when the
55
+
variable gets out of scope. For example when writing a type-checker the
56
+
programmer needs not to care about managing the typing context.
57
+
58
+
- Native support for higher order unification variables, again via HOAS.
59
+
Unification variables of the meta-language (λProlog) can be reused to
60
+
represent the unification variables of the object language. The programmer
61
+
does not need to care about the unification-variable assignment map and
62
+
cannot assign to a unification variable a term containing variables out of
63
+
scope, or build a circular assignment.
64
+
65
+
- Native support for syntactic constraints and their meta-level handling rules.
66
+
The generative semantics of Prolog can be disabled by turning a goal into a
67
+
syntactic constraint (suspended goal). A syntactic constraint is resumed as
68
+
soon as relevant variables gets assigned. Syntactic constraints can be
69
+
manipulated by constraint handling rules (CHR).
70
+
71
+
- Native support for backtracking. To ease implementation of search.
72
+
73
+
- The constraint store is extensible. The host application can declare
74
+
non-syntactic constraints and use custom constraint solvers to check their
75
+
consistency.
76
+
77
+
- Clauses are graftable. The user is free to extend an existing program by
78
+
inserting/removing clauses, both at runtime (using implication) and at
79
+
"compilation" time by accumulating files.

+
