Module Misc

module Misc: sig .. end

The lexicographic order supported by the provided order. There is no constraint on the relative lengths of the lists.

val edit_distance : string -> string -> int -> int option

edit_distance a b cutoff computes the edit distance between strings a and b. To help efficiency, it uses a cutoff: if the distance d is smaller than cutoff, it returns Some d, else None.

The distance algorithm currently used is Damerau-Levenshtein: it computes the number of insertion, deletion, substitution of letters, or swapping of adjacent letters to go from one word to the other. The particular algorithm may change in the future.

val spellcheck : string list -> string -> string list

spellcheck env name takes a list of names env that exist in the current environment and an erroneous name, and returns a list of suggestions taken from env, that are close enough to name that it may be a typo for one of them.

val did_you_mean : Format.formatter -> (unit -> string list) -> unit

did_you_mean ppf get_choices hints that the user may have meant one of the option returned by calling get_choices. It does nothing if the returned list is empty.

The unit -> ... thunking is meant to delay any potentially-slow computation (typically computing edit-distance with many things from the current environment) to when the hint message is to be printed. You should print an understandable error message before calling did_you_mean, so that users get a clear notification of the failure even if producing the hint is slow.

val split : string -> char -> string list

String.split string char splits the string string at every char char, and returns the list of sub-strings between the chars. String.concat (String.make 1 c) (String.split s c) is the identity.
Since 4.01

val cut_at : string -> char -> string * string

String.cut_at s c returns a pair containing the sub-string before the first occurrence of c in s, and the sub-string after the first occurrence of c in s.

let (before, after) = String.cut_at s c in
    before ^ String.make 1 c ^ after

is the identity if s contains c.

Raise Not_found if the character does not appear in the string

val normalise_eol : string -> string

normalise_eol s returns a fresh copy of s with any '\r' characters removed. Intended for pre-processing text which will subsequently be printed on a channel which performs EOL transformations (i.e. Windows)
