       This package provides:

     

       5
       5
       +
       - A lambdapi command for checking .lp or .dk files,

     

       6
       6
       +
       translating .dk files to .lp files and vice versa,

     

       7
       7
       +
       or launching an LSP server for editing .lp files.

       - A library of logic definitions and basic definitions and proofs

     

       9

       +
       on natural numbers and polymorphic lists.

     

       10
       10
       +
       - A rich Emacs mode based on LSP (available on MELPA too).

     

       11
       11
       +
       - A basic mode for Vim.

       Lambdapi provides a rich type system with dependent types.

     

       18
       18
       +
       In Lambdapi, one can define both type and function symbols

     

       19
       19
       +
       by using rewriting rules (oriented equations).

     

       20
       20
       +
       A symbol can be declared associative and commutative.

     

       21
       21
       +
       Lambdapi supports unicode symbols and infix operators.

     

       22
       22
       +
       The declaration of symbols and rewriting rules is separated

     

       23
       23
       +
       so that one can easily define inductive-recursive types.

     

       24
       24
       +
       

     

       25
       25
       +
       Lambdapi checks that rules are locally confluent (by checking

     

       26
       26
       +
       the joinability of critical pairs) and preserve typing.

     

       27
       27
       +
       Rewrite rules can also be exported to the TRS and XTC formats

     

       28
       28
       +
       for checking confluence and termination with external tools.

     

       29
       29
       +
       

     

       30
       30
       +
       Lambdapi does not come with a pre-defined logic. It is a

     

       31
       31
       +
       powerful logical framework in which one can easily define

     

       32
       32
       +
       its own logic and build and check proofs in this logic.

     

       33
       33
       +
       There exist .lp files defining first or higher-order logic

     

       34
       34
       +
       and complex type systems like in Coq or Agda.

     

       35
       35
       +
       

     

       36
       36
       +
       Lambdapi provides a basic module and package system,

     

       37
       37
       +
       interactive modes for proving both unification goals

     

       38
       38
       +
       and typing goals, and tactics for solving them step by step.

     

       39
       39
       +
       In particular, a rewrite tactic like in SSReflect, and

     

       40
       40
       +
       a why3 tactic for calling external automated provers through

     

       41
       41
       +
       the Why3 platform."""
