Module `Proof_diffs`

val opt_name : string list: Name of Diffs option

val show_diffs : unit -> bool: Returns true if the diffs option is "on" or "removed"

val show_removed : unit -> bool: Returns true if the diffs option is "removed"

val write_color_enabled : bool -> unit: controls whether color output is enabled

val color_enabled : unit -> bool: true indicates that color output is enabled

type diffOpt = | DiffOff | DiffOn | DiffRemoved

val string_to_diffs : string -> diffOpt

val diff_goal_ide : (Goal.goal * Evd.evar_map) option -> Goal.goal -> Evd.evar_map -> Pp.t list * Pp.t

Computes the diff between the goals of two Proofs and returns the highlighted lists of hypotheses and conclusions.

If the strings used to display the goal are not lexable (this is believed unlikely), this routine will generate a Diff_Failure. This routine may also raise Diff_Failure under some "impossible" conditions.

If you want to make your call especially bulletproof, catch these exceptions, print a user-visible message, then recall this routine with the first argument set to None, which will skip the diff.

val diff_goal : ?⁠og_s:(Goal.goal * Evd.evar_map) -> Goal.goal -> Evd.evar_map -> Pp.t

Computes the diff between two goals

If you want to make your call especially bulletproof, catch these exceptions, print a user-visible message, then recall this routine with the first argument set to None, which will skip the diff.

val tokenize_string : string -> string list: Convert a string to a list of token strings using the lexer

val pr_leconstr_env : ?⁠lax:bool -> ?⁠inctx:bool -> ?⁠scope:Notation_term.scope_name -> Environ.env -> Evd.evar_map -> EConstr.constr -> Pp.t
val pr_lconstr_env : ?⁠lax:bool -> ?⁠inctx:bool -> ?⁠scope:Notation_term.scope_name -> Environ.env -> Evd.evar_map -> Constr.constr -> Pp.t
val diff_concl : ?⁠og_s:(Goal.goal * Evd.evar_map) -> Evd.evar_map -> Goal.goal -> Pp.t: Computes diffs for a single conclusion

val make_goal_map : Proof.t option -> Proof.t -> Goal.goal Evar.Map.t

Generates a map from np to op that maps changed goals to their prior forms. The map doesn't include entries for unchanged goals; unchanged goals will have the same goal id in both versions.

op and np must be from the same proof document and op must be for a state before np.
