Module Dot.Default

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

Parameters

Signature

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
