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.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
