Functor Dot.Default

module Default: functor (S : Res.S) -> Arg  with type atom := S.atom
                                 and type hyp := S.clause
                                 and type lemma := S.clause
                                 and type assumption := S.clause

Provides a reasonnable default to instantiate the Make functor, assuming the original printing functions are compatible with DOT html labels.

Parameters:

S : Res.S

Term printing for DOT

This module defines what functions are required in order to export a proof to the DOT format.

type atom

The type of atomic formuals

type hyp

type lemma

type assumption

The type of theory-specifi proofs (also called lemmas).

val print_atom : Format.formatter -> atom -> unit

Print the contents of the given atomic formulas. WARNING: this function should take care to escape and/or not output special reserved characters for the dot format (such as quotes and so on).

val hyp_info : hyp ->
       string * string option * (Format.formatter -> unit -> unit) list

val lemma_info : lemma ->
       string * string option * (Format.formatter -> unit -> unit) list

val assumption_info : assumption ->
       string * string option * (Format.formatter -> unit -> unit) list

Generate some information about the leafs of the proof tree. Currently this backend print each lemma/assumption/hypothesis as a single leaf of the proof tree. These function should return a triplet (rule, color, l), such that:

rule is a name for the proof (arbitrary, does not need to be unique, but should rather be descriptive)
color is a color name (optional) understood by DOT
l is a list of printers that will be called to print some additional information
