Various non Sail specific utility functions

val opt_colors : bool ref

val opt_verbosity : int ref

val last : 'a list -> 'a

val last_opt : 'a list -> 'a option

val butlast : 'a list -> 'a list

module Duplicate (S : Set.S) : sig ... end

Mixed useful things

val remove_duplicates : 'a list -> 'a list

remove_duplicates l removes duplicate elements from the list l. As a side-effect, the list might be reordered.

val remove_dups : ('a -> 'a -> int) -> ('a -> 'a -> bool) -> 'a list -> 'a list

remove_dups compare eq l as remove_duplicates but with parameterised comparison and equality

val lex_ord_list : ('a -> 'a -> int) -> 'a list -> 'a list -> int

Lift a comparison order to the lexical order on lists

val assoc_equal_opt : ('a -> 'a -> bool) -> 'a -> ('a * 'b) list -> 'b option

assoc_equal_opt and assoc_compare_opt are like List.assoc_opt but take equality/comparison functions as arguments, rather than relying on OCaml's built in equality

val assoc_compare_opt : ('a -> 'a -> int) -> 'a -> ('a * 'b) list -> 'b option

val power : int -> int -> int

val map_last : (bool -> 'a -> 'b) -> 'a list -> 'b list

Map but pass true to the function for the last element

val iter_last : (bool -> 'a -> unit) -> 'a list -> unit

Option Functions

val option_cases : 'a option -> ('a -> 'b) -> (unit -> 'b) -> 'b

option_cases None f_s f_n returns f_n, whereas option_cases (Some x) f_s f_n returns f_s x.

val option_binop : ('a -> 'a -> 'b) -> 'a option -> 'a option -> 'b option

option_binop f (Some x) (Some y) returns Some (f x y), and in all other cases, option_binop returns None.

val option_get_exn : exn -> 'a option -> 'a

option_get_exn exn None throws the exception exn, whereas option_get_exn exn (Some x) returns x.

val option_these : 'a option list -> 'a list

option_these xs extracts the elements of the list xs wrapped in Some.

val option_all : 'a option list -> 'a list option

option_all xs extracts the elements of the list xs if all of them are wrapped in Some. If any are None then the result is None is None. option_all [] is Some []

List Functions

val list_empty : 'a list -> bool

val list_index : ('a -> bool) -> 'a list -> int option

list_index p l returns the first index i such that the predicate p (l!i) holds. If no such i exists, None is returned.

val option_first : ('a -> 'b option) -> 'a list -> 'b option

option_first f l searches for the first element x of l such that the f x is not None. If such an element exists, f x is returned, otherwise None.

val map_changed : ('a -> 'a option) -> 'a list -> 'a list option

map_changed f l maps f over l. If for all elements of l the function f returns None, then map_changed f l returns None. Otherwise, it uses x for all elements, where f x returns None, and returns the resulting list.

val map_changed_default : 
  ('a -> 'b) ->
  ('a -> 'b option) ->
  'a list ->
  'b list option

map_changed_default d f l maps f over l. If for all elements of l the function f returns None, then map_changed f l returns None. Otherwise, it uses d x for all elements x, where f x returns None, and returns the resulting list.

val list_iter_sep : (unit -> unit) -> ('a -> unit) -> 'a list -> unit

list_iter sf f [a1; ...; an] applies function f in turn to a1; ...; an and calls sf () in between. It is equivalent to begin f a1; sf(); f a2; sf(); ...; f an; () end.

val map_split : ('a -> ('b, 'c) result) -> 'a list -> 'b list * 'c list

val map_all : ('a -> 'b option) -> 'a list -> 'b list option

map_all f l maps f over l. If at least one entry is None, None is returned. Otherwise, the Some function is removed from the list.

val list_to_front : int -> 'a list -> 'a list

list_to_front i l resorts the list l by bringing the element at index i to the front. @throws Failure if i is not smaller than the length of l

val undo_list_to_front : int -> 'a list -> 'a list

undo_list_to_front i l resorts the list l by moving the head element to index index i It's the inverse of list_to_front i l.

val split_after : int -> 'a list -> 'a list * 'a list

split_after n l splits the first n elemenst from list l, i.e. it returns two lists l1 and l2, with length l1 = n and l1 @ l2 = l. Fails if n is too small or large.

val split3 : ('a * 'b * 'c) list -> 'a list * 'b list * 'c list

split3 l splits a list of triples into a triple of lists

val compare_list : ('a -> 'b -> int) -> 'a list -> 'b list -> int

val take : int -> 'a list -> 'a list

val drop : int -> 'a list -> 'a list

val take_drop : ('a -> bool) -> 'a list -> 'a list * 'a list

val find_rest_opt : ('a -> bool) -> 'a list -> ('a * 'a list) option

val find_next : ('a -> bool) -> 'a list -> 'a list * ('a * 'a list) option

val find_index_opt : ('a -> bool) -> 'a list -> (int * 'a) option

find an item in a list and return that item as well as its index

val find_map : ('a -> 'b option) -> 'a list -> 'b option

val fold_left_concat_map : 
  ('a -> 'b -> 'a * 'c list) ->
  'a ->
  'b list ->
  'a * 'c list

val fold_left_last : (bool -> 'a -> 'b -> 'a) -> 'a -> 'b list -> 'a

val fold_left_index : (int -> 'a -> 'b -> 'a) -> 'a -> 'b list -> 'a

val fold_left_index_last : 
  (int -> bool -> 'a -> 'b -> 'a) ->
  'a ->
  'b list ->
  'a

val list_init : int -> (int -> 'a) -> 'a list

Files

val copy_file : string -> string -> unit

copy_file src dst copies file src to file dst. Only files are supported, no directories.

val move_file : string -> string -> unit

move_file src dst moves file src to file dst. In contrast to Sys.rename no error is produced, if dst already exists. Moreover, in case Sys.rename fails for some reason (e.g. because it does not work over filesystem boundaries), copy_file and Sys.remove are used as fallback.

val input_byte_opt : in_channel -> int option

input_byte_opt chan tries to read a byte b from input channel chan, and returns Some b in case of success, or None if the end of the file was reached.

val same_content_files : string -> string -> bool

same_content_files file1 file2 checks, whether the files file1 and file2 have the same content. If at least one of the files does not exist, false is returned. same_content_files throws an exception, if one of the files exists, but cannot be read.

Strings

val string_to_list : string -> char list

string_to_list l translates the string l to the list of its characters.

Useful Sets

module IntSet : Set.S with type elt = int

Sets of Integers

module IntIntSet : Set.S with type elt = int * int

Formatting functions

val string_of_list : string -> ('a -> string) -> 'a list -> string

val string_of_option : ('a -> string) -> 'a option -> string

val split_on_char : char -> string -> string list

Terminal color codes

val termcode : int -> string

val bold : string -> string

val dim : string -> string

val darkgray : string -> string

val green : string -> string

val red : string -> string

val red_bg : string -> string

val yellow : string -> string

val cyan : string -> string

val blue : string -> string

val magenta : string -> string

val clear : string -> string

Encoding schemes for strings

z-encoding will take any string with ASCII characters in the range 32-126 inclusive, and map it to a string that just contains ASCII upper and lower case letters and numbers, prefixed with the letter z. This mapping is one-to-one.

val zencode_string : string -> string

val zencode_upper_string : string -> string

val file_encode_string : string -> string

Encode string for use as a filename. We can't use zencode directly because some operating systems make the mistake of being case-insensitive.

Misc output functions

val log_line : string -> int -> string -> string

val header : string -> int -> string

val progress : string -> string -> int -> int -> unit

val always_replace_files : bool ref

always_replace_files determines whether Sail only updates modified files. If it is set to true, all output files are written, regardless of whether the files existed before. If it is set to false and an output file already exists, the output file is only updated, if its content really changes.

val open_output_with_check : 
  string option ->
  string ->
  Format.formatter * (out_channel * string * string option * string)

val open_output_with_check_unformatted : 
  string option ->
  string ->
  out_channel * string * string option * string

val close_output_with_check : 
  (out_channel * string * string option * string) ->
  unit
