Module `BatString`

String operations.

Given a string s of length l, we call character number in s the index of a character in s. Indexes start at 0, and we will call a character number valid in s if it falls within the range [0...l-1]. A position is the point between two characters or at the beginning or end of the string. We call a position valid in s if it falls within the range [0...l]. Note that character number n is between positions n and n+1.

Two parameters start and len are said to designate a valid substring of s if len >= 0 and start and start+len are valid positions in s.

OCaml strings can be modified in place, for instance via the String.set and String.blit functions described below. This possibility should be used rarely and with much care, however, since both the OCaml compiler and most OCaml libraries share strings as if they were immutable, rather than copying them. In particular, string literals are shared: a single copy of the string is created at program loading time and returned by all evaluations of the string literal. Consider for example:

  # let f () = "foo";;
  val f : unit -> string = <fun>
      # (f ()).[0] <- 'b';;
  -: unit = ()
    # f ();;
  -: string = "boo"

Likewise, many functions from the standard library can return string literals or one of their string arguments. Therefore, the returned strings must not be modified directly. If mutation is absolutely necessary, it should be performed on a fresh copy of the string, as produced by String.copy.

This module replaces Stdlib's String module.

If you're going to do a lot of string slicing, BatSubstring might be a useful module to represent slices of strings, as it doesn't allocate new strings on every operation.

Conversions

val enum : string -> char BatEnum.t

Returns an enumeration of the characters of a string. The behaviour is unspecified if the string is mutated while it is enumerated.

Examples: "foo" |> String.enum |> List.of_enum = ['f'; 'o'; 'o'] String.enum "a b c" // ((<>) ' ') |> String.of_enum = "abc"

val of_enum : char BatEnum.t -> string

Creates a string from a character enumeration. Example: ['f'; 'o'; 'o'] |> List.enum |> String.of_enum = "foo"

val backwards : string -> char BatEnum.t

Returns an enumeration of the characters of a string, from last to first.

Examples: "foo" |> String.backwards |> String.of_enum = "oof" let rev s = String.backwards s |> String.of_enum

val of_backwards : char BatEnum.t -> string

Build a string from an enumeration, starting with last character, ending with first.

val of_list : char list -> string

Converts a list of characters to a string.

Example: ['c'; 'h'; 'a'; 'r'; 's'] |> String.of_list = "chars"

val to_list : string -> char list

Converts a string to the list of its characters.

Example: String.to_list "string" |> List.interleave ';' |> String.of_list = "s;t;r;i;n;g"

Example: String.of_float 1.246 = "1.246"

val of_char : char -> string

Returns a string containing one given character.

Example: String.of_char 's' = "s"

val to_int : string -> int

Returns the integer represented by the given string or

raises Failure
if the string does not represent an integer. This follows OCaml's int literal rules, so "0x" prefixes hexadecimal integers, "0o" for octal and "0b" for binary. Underscores within the number are allowed for readability but ignored.

Examples: String.to_int "8_480" = String.to_int "0x21_20" try ignore(String.to_int "2,3"); false with Failure _ -> true

raises Failure
if the string does not represent an integer.

val to_float : string -> float

Returns the float represented by the given string or

raises Failure
if the string does not represent a float. Decimal points aren't required in the given string, as they are for float literals in OCaml, but otherwise the rules for float literals apply.

Examples: String.to_float "12.34e-1" = String.to_float "1.234" String.to_float "1" = 1. try ignore(String.to_float ""); false with Failure _ -> true

raises Failure
if the string does not represent a float.

String traversals

val map : (char -> char) -> string -> string

map f s returns a string where all characters c in s have been replaced by f c.

Example: String.map Char.uppercase "Five" = "FIVE" *

val fold_left : ('a -> char -> 'a) -> 'a -> string -> 'a

val fold_right : (char -> 'a -> 'a) -> string -> 'a -> 'a

fold_right f s b is f s.[0] (f s.[1] (... (f s.[n-1] b) ...))

Examples: String.fold_right List.cons "foo" [] = ['f';'o';'o'] String.fold_right (fun c a -> if c = ' ' then a+1 else a) "a b c" 0 = 2

val fold_righti : (int -> char -> 'a -> 'a) -> string -> 'a -> 'a

since 2.3.0

val filter : (char -> bool) -> string -> string

filter f s returns a copy of string s in which only characters c such that f c = true remain.

Example: String.filter ((<>) ' ') "a b c" = "abc"

val filter_map : (char -> char option) -> string -> string

filter_map f s calls (f a0) (f a1).... (f an) where a0..an are the characters of s. It returns the string of characters ci such as f ai = Some ci (when f returns None, the corresponding element of s is discarded).

Example: String.filter_map (function 'a'..'z' as c -> Some (Char.uppercase c) | _ -> None) "a b c" = "ABC"

val iteri : (int -> char -> unit) -> string -> unit

String.iteri f s is equivalent to f 0 s.[0]; f 1 s.[1]; ...; f len s.[len] where len is length of string s. Example:

 let letter_positions word =
  let positions = Array.make 256 [] in
  let count_letter pos c =
    positions.(int_of_char c) <- pos :: positions.(int_of_char c) in
  String.iteri count_letter word;
  Array.mapi (fun c pos -> (char_of_int c, List.rev pos)) positions
  |> Array.to_list
  |> List.filter (fun (c,pos) -> pos <> [])
  in
  letter_positions "hello" = ['e',[1]; 'h',[0]; 'l',[2;3]; 'o',[4] ]

Finding

val find : string -> string -> int

find s x returns the starting index of the first occurrence of string x within string s.

Note This implementation is optimized for short strings.

raises Not_found
if x is not a substring of s.

Example: String.find "foobarbaz" "bar" = 3

val find_from : string -> int -> string -> int

find_from s pos x behaves as find s x but starts searching at position pos. find s x is equivalent to find_from s 0 x.

raises Not_found
if not substring is found

raises Invalid_argument
if pos is not a valid position in the string.

Example: String.find_from "foobarbaz" 4 "ba" = 6

val rfind : string -> string -> int

rfind s x returns the starting index of the last occurrence of string x within string s.

Note This implementation is optimized for short strings.

raises Not_found
if x is not a substring of s.

Example: String.rfind "foobarbaz" "ba" = 6

val rfind_from : string -> int -> string -> int

rfind_from s pos x behaves as rfind s x but starts searching from the right at position pos + 1. rfind s x is equivalent to rfind_from s (String.length s - 1) x.

Beware, it search between the beginning of the string to the position pos + 1, not between pos + 1 and the end.

raises Not_found
if not substring is found

raises Invalid_argument
if pos is not a valid position in the string.

Example: String.rfind_from "foobarbaz" 6 "ba" = 6

val find_all : string -> string -> int BatEnum.t

find_all s x enumerates positions of s at which x occurs. Example: find_all "aabaabaa" "aba" |> List.of_enum will return the list [1; 4].

Example: String.ends_with "foobarbaz" "rbaz" = true

val starts_with : string -> string -> bool

starts_with s x returns true if s is starting with x, false otherwise.

Example: String.starts_with "foobarbaz" "fooz" = false

Transformations

val lchop : ?n:int -> string -> string

Returns the same string but without the first n characters. By default n is 1. If n is strictly less than zero

raises Invalid_argument.
If the string has n or less characters, returns the empty string.

Example: String.lchop "Weeble" = "eeble" String.lchop ~n:3 "Weeble" = "ble" String.lchop ~n:1000 "Weeble" = ""

val rchop : ?n:int -> string -> string

Returns the same string but without the last n characters. By default n is 1. If n is strictly less than zero

raises Invalid_argument.
If the string has n or less characters , returns the empty string.

Example: String.rchop "Weeble" = "Weebl" String.rchop ~n:3 "Weeble" = "Wee" String.rchop ~n:1000 "Weeble" = ""

val chop : ?l:int -> ?r:int -> string -> string

Returns the same string but with the first l characters on the left and the first r characters on the right removed. By default, l and r are both 1.

chop ~l ~r s is equivalent to lchop ~n:l (rchop ~n:r s).

raises Invalid_argument
if either l or r is less than zero.

Examples: String.chop "\"Weeble\"" = "Weeble" String.chop ~l:2 ~r:3 "01234567" = "234"

val trim : string -> string

Returns the same string but without the leading and trailing whitespaces (according to BatChar.is_whitespace).

Example: String.trim " \t foo\n " = "foo"

val quote : string -> string

Add quotes around a string and escape any quote or escape appearing in that string. This function is used typically when you need to generate source code from a string.

Examples: String.quote "foo" = "\"foo\"" String.quote "\"foo\"" = "\"\\\"foo\\\"\"" String.quote "\n" = "\"\\n\"" etc.

More precisely, the returned string conforms to the OCaml syntax: if printed, it outputs a representation of the input string as an OCaml string litteral.

val left : string -> int -> string

left r len returns the string containing the len first characters of r. If r contains less than len characters, it returns r.

Examples: String.left "Weeble" 4 = "Weeb" String.left "Weeble" 0 = "" String.left "Weeble" 10 = "Weeble"

val right : string -> int -> string

right r len returns the string containing the len last characters of r. If r contains less than len characters, it returns r.

Example: String.right "Weeble" 4 = "eble"

val head : string -> int -> string

as left

val tail : string -> int -> string

tail r pos returns the string containing all but the pos first characters of r

Example: String.tail "Weeble" 4 = "le"

val strip : ?chars:string -> string -> string

Returns the string without the chars if they are at the beginning or at the end of the string. By default chars are " \t\r\n".

Examples: String.strip " foo " = "foo" String.strip ~chars:" ,()" " boo() bar()" = "boo() bar"

val replace_chars : (char -> string) -> string -> string

replace_chars f s returns a string where all chars c of s have been replaced by the string returned by f c.

Example: String.replace_chars (function ' ' -> "(space)" | c -> String.of_char c) "foo bar" = "foo(space)bar"

val replace : str:string -> sub:string -> by:string -> bool * string

replace ~str ~sub ~by returns a tuple consisting of a boolean and a string where the first occurrence of the string sub within str has been replaced by the string by. The boolean is true if a substitution has taken place.

Example: String.replace "foobarbaz" "bar" "rab" = (true, "foorabbaz")

val nreplace : str:string -> sub:string -> by:string -> string

nreplace ~str ~sub ~by returns a string obtained by iteratively replacing each occurrence of sub by by in str, from right to left. It returns a copy of str if sub has no occurrence in str.

Example: nreplace ~str:"bar foo aaa bar" ~sub:"aa" ~by:"foo" = "bar foo afoo bar"

val repeat : string -> int -> string

repeat s n returns s ^ s ^ ... ^ s

Example: String.repeat "foo" 4 = "foofoofoofoo"

val rev : string -> string

rev s returns the reverse of string s

since 2.1

In-Place Transformations

val rev_in_place : Bytes.t -> unit

rev_in_place s mutates the byte sequence s, so that its new value is the mirror of its old one: for instance if s contained "Example!", after the mutation it will contain "!elpmaxE".

val in_place_mirror : Bytes.t -> unit

deprecated
Use String.rev_in_place instead

Splitting around

val split_on_char : char -> string -> string list

String.split_on_char sep s returns the list of all (possibly empty) substrings of s that are delimited by the sep character.

The function's output is specified by the following invariants:

The list is not empty.
Concatenating its elements using sep as a separator returns a string equal to the input (String.concat (String.make 1 sep) (String.split_on_char sep s) = s).
No string in the result contains the sep character.

Note: prior to 2.11.0 split_on_char _ "" used to return an empty list.

since 2.5.3

val split : string -> by:string -> string * string

split s sep splits the string s between the first occurrence of sep, and returns the two parts before and after the occurrence (excluded).

raises Not_found
if the separator is not found.

Examples: String.split "abcabcabc" "bc" = ("a","abcabc") String.split "abcabcabc" "" = ("","abcabcabc")

val rsplit : string -> by:string -> string * string

rsplit s sep splits the string s between the last occurrence of sep, and returns the two parts before and after the occurrence (excluded).

raises Not_found
if the separator is not found.

Example: String.rsplit "abcabcabc" "bc" = ("abcabca","")

val nsplit : string -> by:string -> string list

nsplit s sep splits the string s into a list of strings which are separated by sep (excluded). nsplit "" _ returns a single empty string. Note: prior to 2.11.0 nsplit "" _ used to return an empty list.

Example: String.nsplit "abcabcabc" "bc" = ["a"; "a"; "a"; ""]

deprecated
use split_on_string

val split_on_string : by:string -> string -> string list

split_on_string sep s splits the string s into a list of strings which are separated by sep (excluded). split_on_string _ "" returns a single empty string. Note: split_on_string sep s is identical to nsplit s sep but for empty strings.

Example: String.split_on_string "bc" "abcabcabc" = ["a"; "a"; "a"; ""]

val cut_on_char : char -> int -> string -> string

Similar to Unix cut. cut_on_char chr n str returns the substring of str located strictly between the n-th occurrence of chr and the n+1-th one.

Occurrences of chr are numbered from 1.
If n = 0, returns the substring from the beginning of str to the first occurrence of chr.
If there are exactly n occurrences of chr in str, returns the substring between the last occurrence of chr and the end of str.
These behaviours cumulate: if n equals 0 and chr is absent from str, returns the full string str.

Remark: cut_on_char can return the empty string. Examples of this behaviour are cut_on_char ',' 1 "foo,,bar" and cut_on_char ',' 0 ",foo".

raises Not_found
if there are strictly less than n occurrences of chr in str.

raises Invalid_argument
if n < 0.

since 2.9.0

val join : string -> string list -> string

Same as concat

val slice : ?first:int -> ?last:int -> string -> string

slice ?first ?last s returns a "slice" of the string which corresponds to the characters s.[first], s.[first+1], ..., s[last-1]. Note that the character at index last is not included! If first is omitted it defaults to the start of the string, i.e. index 0, and if last is omitted is defaults to point just past the end of s, i.e. length s. Thus, slice s is equivalent to copy s.

Negative indexes are interpreted as counting from the end of the string. For example, slice ~last:(-2) s will return the string s, but without the last two characters.

This function never raises any exceptions. If the indexes are out of bounds they are automatically clipped.

Example: String.slice ~first:1 ~last:(-3) " foo bar baz" = "foo bar "

val splice : string -> int -> int -> string -> string

String.splice s off len rep cuts out the section of s indicated by off and len and replaces it by rep

Negative indexes are interpreted as counting from the end of the string. If off+len is greater than length s, the end of the string is used, regardless of the value of len.

If len is zero or negative, rep is inserted at position off without replacing any of s.

Example: String.splice "foo bar baz" 3 5 "XXX" = "fooXXXbaz"

val explode : string -> char list

explode s returns the list of characters in the string s.

Example: String.explode "foo" = ['f'; 'o'; 'o']

val implode : char list -> string

implode cs returns a string resulting from concatenating the characters in the list cs.

Example: String.implode ['b'; 'a'; 'r'] = "bar"

Iterators

val to_seq : t -> char Seq.t

Iterate on the string, in increasing index order. Modifications of the string during iteration will be reflected in the iterator.

since 2.10.0 and OCaml 4.07

val to_seqi : t -> (int * char) Seq.t

Iterate on the string, in increasing order, yielding indices along chars

since 2.10.0 and OCaml 4.07

Comparisons

val equal : t -> t -> bool

String equality

val ord : t -> t -> BatOrd.order

Ordering function for strings, see BatOrd

val compare : t -> t -> int

The comparison function for strings, with the same specification as Pervasives.compare. Along with the type t, this function compare allows the module String to be passed as argument to the functors Set.Make and Map.Make.

Example: String.compare "FOO" "bar" = -1 i.e. "FOO" < "bar"

val icompare : t -> t -> int

Compare two strings, case-insensitive.

Example: String.icompare "FOO" "bar" = 1 i.e. "foo" > "bar"

module IString : BatInterfaces.OrderedType with type t = t

uses icompare as ordering function

val numeric_compare : t -> t -> int

Compare two strings, sorting "abc32def" before "abc210abc".

Algorithm: splits both strings into lists of (strings of digits) or (strings of non digits) (["abc"; "32"; "def"] and ["abc"; "210"; "abc"]) Then both lists are compared lexicographically by comparing elements numerically when both are numbers or lexicographically in other cases.

Example: String.numeric_compare "xx32" "xx210" < 0

module NumString : BatInterfaces.OrderedType with type t = t

uses numeric_compare as its ordering function

val edit_distance : t -> t -> int

Edition distance (also known as "Levenshtein distance"). See wikipedia

since 2.2.0

Boilerplate code

Printing

val print : 'a BatInnerIO.output -> string -> unit

Print a string.

Example: String.print stdout "foo\n"

val println : 'a BatInnerIO.output -> string -> unit

Print a string, end the line.

Example: String.println stdout "foo"

val print_quoted : 'a BatInnerIO.output -> string -> unit

Print a string, with quotes as added by the quote function.

String.print_quoted stdout "foo" prints "foo" (with the quotes).

String.print_quoted stdout "\"bar\"" prints "\"bar\"" (with the quotes).

String.print_quoted stdout "\n" prints "\n" (not the escaped character, but '\' then 'n').
