Module Pervasives

+
+
module Pervasives: sig .. end
The initially opened module. +

+ + This module provides the basic operations over the built-in types + (numbers, booleans, strings, exceptions, references, lists, arrays, + input-output channels, ...). +

+ + This module is automatically opened at the beginning of each compilation. + All components of this module can therefore be referred by their short + name, without prefixing them by Pervasives.
+

+
+
Exceptions

+
val raise : exn -> 'a
+Raise the given exception value
+
+
val invalid_arg : string -> 'a
+Raise exception Invalid_argument with the given string.
+
+
val failwith : string -> 'a
+Raise exception Failure with the given string.
+
+
exception Exit
+
+The Exit exception is not raised by any library function. It is + provided for use in your programs.
+
+
+
Comparisons

+
val (=) : 'a -> 'a -> bool
+e1 = e2 tests for structural equality of e1 and e2. + Mutable structures (e.g. references and arrays) are equal + if and only if their current contents are structurally equal, + even if the two mutable objects are not the same physical object. + Equality between functional values raises Invalid_argument. + Equality between cyclic data structures may not terminate.
+
+
val (<>) : 'a -> 'a -> bool
+Negation of (=).
+
+
val (<) : 'a -> 'a -> bool
+See (>=).
+
+
val (>) : 'a -> 'a -> bool
+See (>=).
+
+
val (<=) : 'a -> 'a -> bool
+See (>=).
+
+
val (>=) : 'a -> 'a -> bool
+Structural ordering functions. These functions coincide with + the usual orderings over integers, characters, strings + and floating-point numbers, and extend them to a + total ordering over all types. + The ordering is compatible with (=). As in the case + of (=), mutable structures are compared by contents. + Comparison between functional values raises Invalid_argument. + Comparison between cyclic structures may not terminate.
+
+
val compare : 'a -> 'a -> int
+compare x y returns 0 if x is equal to y, + a negative integer if x is less than y, and a positive integer + if x is greater than y. The ordering implemented by compare + is compatible with the comparison predicates =, < and > + defined above, with one difference on the treatment of the float value + nan. Namely, the comparison predicates treat nan + as different from any other float value, including itself; + while compare treats nan as equal to itself and less than any + other float value. This treatment of nan ensures that compare + defines a total ordering relation. +

+ + compare applied to functional values may raise Invalid_argument. + compare applied to cyclic structures may not terminate. +

+ + The compare function can be used as the comparison function + required by the Set.Make and Map.Make functors, as well as + the List.sort and Array.sort functions.
+

+
val min : 'a -> 'a -> 'a
+Return the smaller of the two arguments. + The result is unspecified if one of the arguments contains + the float value nan.
+
+
val max : 'a -> 'a -> 'a
+Return the greater of the two arguments. + The result is unspecified if one of the arguments contains + the float value nan.
+
+
val (==) : 'a -> 'a -> bool
+e1 == e2 tests for physical equality of e1 and e2. + On mutable types such as references, arrays, strings, records with + mutable fields and objects with mutable instance variables, + e1 == e2 is true if and only if physical modification of e1 + also affects e2. + On non-mutable types, the behavior of (==) is + implementation-dependent; however, it is guaranteed that + e1 == e2 implies compare e1 e2 = 0.
+
+
val (!=) : 'a -> 'a -> bool
+Negation of (==).
+
+
+
Boolean operations

+
val not : bool -> bool
+The boolean negation.
+
+
val (&&) : bool -> bool -> bool
+The boolean ``and''. Evaluation is sequential, left-to-right: + in e1 && e2, e1 is evaluated first, and if it returns false, + e2 is not evaluated at all.
+
+
val (&) : bool -> bool -> bool
+Deprecated.(&&) should be used instead.
+
+
val (||) : bool -> bool -> bool
+The boolean ``or''. Evaluation is sequential, left-to-right: + in e1 || e2, e1 is evaluated first, and if it returns true, + e2 is not evaluated at all.
+
+
val (or) : bool -> bool -> bool
+Deprecated.(||) should be used instead.
+
+
+
Integer arithmetic

+
+Integers are 31 bits wide (or 63 bits on 64-bit processors). + All operations are taken modulo 231 (or 263). + They do not fail on overflow.
+
val (~-) : int -> int
+Unary negation. You can also write - e instead of ~- e.
+
+
val (~+) : int -> int
+Unary addition. You can also write + e instead of ~+ e.
+Since 3.12.0
+
+
val succ : int -> int
+succ x is x + 1.
+
+
val pred : int -> int
+pred x is x - 1.
+
+
val (+) : int -> int -> int
+Integer addition.
+
+
val (-) : int -> int -> int
+Integer subtraction.
+
+
val ( * ) : int -> int -> int
+Integer multiplication.
+
+
val (/) : int -> int -> int
+Integer division. + Raise Division_by_zero if the second argument is 0. + Integer division rounds the real quotient of its arguments towards zero. + More precisely, if x >= 0 and y > 0, x / y is the greatest integer + less than or equal to the real quotient of x by y. Moreover, + (- x) / y = x / (- y) = - (x / y).
+
+
val (mod) : int -> int -> int
+Integer remainder. If y is not zero, the result + of x mod y satisfies the following properties: + x = (x / y) * y + x mod y and + abs(x mod y) <= abs(y) - 1. + If y = 0, x mod y raises Division_by_zero. + Note that x mod y is negative only if x < 0. + Raise Division_by_zero if y is zero.
+
+
val abs : int -> int
+Return the absolute value of the argument. Note that this may be + negative if the argument is min_int.
+
+

+
+
val min_int : int
+The smallest representable integer.
+

+
+

+n lsl m shifts n to the left by m bits. + The result is unspecified if m < 0 or m >= bitsize, + where bitsize is 32 on a 32-bit platform and + 64 on a 64-bit platform.
+
+
val (lsr) : int -> int -> int
+n lsr m shifts n to the right by m bits. + This is a logical shift: zeroes are inserted regardless of + the sign of n. + The result is unspecified if m < 0 or m >= bitsize.
+
+
val (asr) : int -> int -> int
+n asr m shifts n to the right by m bits. + This is an arithmetic shift: the sign bit of n is replicated. + The result is unspecified if m < 0 or m >= bitsize.
+
+
+
Floating-point arithmetic
 +

+ + Caml's floating-point numbers follow the + IEEE 754 standard, using double precision (64 bits) numbers. + Floating-point operations never raise an exception on overflow, + underflow, division by zero, etc. Instead, special IEEE numbers + are returned as appropriate, such as infinity for 1.0 /. 0.0, + neg_infinity for -1.0 /. 0.0, and nan (``not a number'') + for 0.0 /. 0.0. These special numbers then propagate through + floating-point computations as expected: for instance, + 1.0 /. infinity is 0.0, and any arithmetic operation with nan + as argument returns nan as result.
+

val (~-.) : float -> float
+Unary negation. You can also write -. e instead of ~-. e.

+
+
val nan : float
+A special floating-point value denoting the result of an + undefined operation such as 0.0 /. 0.0. Stands for + ``not a number''.

+Opening modes for open_out_gen and + open_in_gen.
+
+ +
val open_out : string -> out_channel
+Open the named file for writing, and return a new output channel + on that file, positionned at the beginning of the file. The + file is truncated to zero length if it already exists. It + is created if it does not already exists. + Raise Sys_error if the file could not be opened.
+
+
val open_out_bin : string -> out_channel
+Same as open_out, but the file is opened in binary mode, + so that no translation takes place during writes. On operating + systems that do not distinguish between text mode and binary + mode, this function behaves like open_out.
+
+
val open_out_gen : open_flag list -> int -> string -> out_channel
+open_out_gen mode perm filename opens the named file for writing, + as described above. The extra argument mode + specify the opening mode. The extra argument perm specifies + the file permissions, in case the file must be created. + open_out and open_out_bin are special + cases of this function.
+
+
val flush : out_channel -> unit
+Flush the buffer associated with the given output channel, + performing all pending writes on that channel. + Interactive programs must be careful about flushing standard + output and standard error at the right time.
+
+
val flush_all : unit -> unit
+Flush all open output channels; ignore errors.
+
+
val output_char : out_channel -> char -> unit
+Write the character on the given output channel.

val output_string : out_channel -> string -> unit
+Write the string on the given output channel.
+
+

+
+
val output_byte : out_channel -> int -> unit
+Write one 8-bit integer (as the single character with that code) + on the given output channel. The given integer is taken modulo + 256.

val output_binary_int : out_channel -> int -> unit
+Write one integer in binary format (4 bytes, big-endian) + on the given output channel. + The given integer is taken modulo 232. + The only reliable way to read it back is through the + input_binary_int function. The format is compatible across + all machines for a given version of Objective Caml.
+
+
val output_value : out_channel -> 'a -> unit
+Write the representation of a structured value of any type + to a channel. Circularities and sharing inside the value + are detected and preserved. The object can be read back, + by the function input_value. See the description of module + Marshal for more information. output_value is equivalent + to Marshal.to_channel with an empty list of flags.
+
+
val seek_out : out_channel -> int -> unit
+seek_out chan pos sets the current writing position to pos + for channel chan. This works only for regular files. On + files of other kinds (such as terminals, pipes and sockets), + the behavior is unspecified.

+
+
val close_out : out_channel -> unit
+Close the given channel, flushing all buffered write operations. + Output functions raise a Sys_error exception when they are + applied to a closed output channel, except close_out and flush, + which do nothing when applied to an already closed channel. + Note that close_out may raise Sys_error if the operating + system signals an error when flushing or closing.
+
+
val close_out_noerr : out_channel -> unit
+Same as close_out, but ignore all errors.
+
+
val set_binary_mode_out : out_channel -> bool -> unit
+set_binary_mode_out oc true sets the channel oc to binary + mode: no translations take place during output. + set_binary_mode_out oc false sets the channel oc to text + mode: depending on the operating system, some translations + may take place during output. For instance, under Windows, + end-of-lines will be translated from \n to \r\n. + This function has no effect under operating systems that + do not distinguish between text mode and binary mode.
+

+
+
val open_in_gen : open_flag list -> int -> string -> in_channel

+Read one character from the given input channel. + Raise End_of_file if there are no more characters to read.
+
+
val input_line : in_channel -> string
+Read characters from the given input channel, until a + newline character is encountered. Return the string of + all characters read, without the newline character at the end. + Raise End_of_file if the end of the file is reached + at the beginning of line.
+
+
val input : in_channel -> string -> int -> int -> int
+input ic buf pos len reads up to len characters from + the given channel ic, storing them in string buf, starting at + character number pos. + It returns the actual number of characters read, between 0 and + len (inclusive). + A return value of 0 means that the end of file was reached. + A return value between 0 and len exclusive means that + not all requested len characters were read, either because + no more characters were available at that time, or because + the implementation found it convenient to do a partial read; + input must be called again to read the remaining characters, + if desired. (See also really_input for reading + exactly len characters.) + Exception Invalid_argument "input" is raised if pos and len + do not designate a valid substring of buf.

val really_input : in_channel -> string -> int -> int -> unit
+really_input ic buf pos len reads len characters from channel ic, + storing them in string buf, starting at character number pos. + Raise End_of_file if the end of file is reached before len + characters have been read. + Raise Invalid_argument "really_input" if + pos and len do not designate a valid substring of buf.
+
+
val input_byte : in_channel -> int
+Same as input_char, but return the 8-bit integer representing + the character. + Raise End_of_file if an end of file was reached.
+
+
val input_binary_int : in_channel -> int
+Read an integer encoded in binary format (4 bytes, big-endian) + from the given input channel. See output_binary_int. + Raise End_of_file if an end of file was reached while reading the + integer.
+
+
val input_value : in_channel -> 'a
+Read the representation of a structured value, as produced + by output_value, and return the corresponding value. + This function is identical to Marshal.from_channel; + see the description of module Marshal for more information, + in particular concerning the lack of type safety.
+
+
val seek_in : in_channel -> int -> unit
+seek_in chan pos sets the current reading position to pos + for channel chan. This works only for regular files. On + files of other kinds, the behavior is unspecified.
+
+
val pos_in : in_channel -> int
+Return the current reading position for the given channel.
+
+
val in_channel_length : in_channel -> int
+Return the size (number of characters) of the regular file + on which the given channel is opened. If the channel is opened + on a file that is not a regular file, the result is meaningless. + The returned size does not take into account the end-of-line + translations that can be performed when reading from a channel + opened in text mode.
+
+
val close_in : in_channel -> unit
+Close the given channel. Input functions raise a Sys_error + exception when they are applied to a closed input channel, + except close_in, which does nothing when applied to an already + closed channel. Note that close_in may raise Sys_error if + the operating system signals an error.
+
+
val close_in_noerr : in_channel -> unit
+Same as close_in, but ignore all errors.
+
+
val set_binary_mode_in : in_channel -> bool -> unit
+set_binary_mode_in ic true sets the channel ic to binary + mode: no translations take place during input. + set_binary_mode_out ic false sets the channel ic to text + mode: depending on the operating system, some translations + may take place during input. For instance, under Windows, + end-of-lines will be translated from \r\n to \n. + This function has no effect under operating systems that + do not distinguish between text mode and binary mode.

References

+
type 'a ref = { + + + + +
+   +mutable contents : 'a;
+} + +
+The type of references (mutable indirection cells) containing + a value of type 'a.
+
+ +
val ref : 'a -> 'a ref
+Return a fresh reference containing the given value.
+
+
val (!) : 'a ref -> 'a
+!r returns the current contents of reference r. + Equivalent to fun r -> r.contents.
+
+
val (:=) : 'a ref -> 'a -> unit
+r := a stores the value of a in reference r. + Equivalent to fun r v -> r.contents <- v.
+
+
val incr : int ref -> unit
+Increment the integer contained in the given reference. + Equivalent to fun r -> r := succ !r.
+
+
val decr : int ref -> unit
+Decrement the integer contained in the given reference. + Equivalent to fun r -> r := pred !r.
+
+
+
Operations on format strings

+
+Format strings are used to read and print data using formatted input + functions in module Scanf and formatted output in modules Printf and + Format.
+
type ('a, 'b, 'c, 'd) format4 = ('a, 'b, 'c, 'c, 'c, 'd) format6
+
+Format strings have a general and highly polymorphic type + ('a, 'b, 'c, 'd, 'e, 'f) format6. Type format6 is built in. + The two simplified types, format and format4 below are + included for backward compatibility with earlier releases of Objective + Caml. + 'a is the type of the parameters of the format, + 'b is the type of the first argument given to + %a and %t printing functions, + 'c is the type of the argument transmitted to the first argument of + "kprintf"-style functions, + 'd is the result type for the "scanf"-style functions, + 'e is the type of the receiver function for the "scanf"-style functions, + 'f is the result type for the "printf"-style function.
+
+ +
type ('a, 'b, 'c) format = ('a, 'b, 'c, 'c) format4
+ +
val string_of_format : ('a, 'b, 'c, 'd, 'e, 'f) format6 -> string
+Converts a format string into a string.
+
+
val format_of_string : ('a, 'b, 'c, 'd, 'e, 'f) format6 -> ('a, 'b, 'c, 'd, 'e, 'f) format6
+format_of_string s returns a format string read from the string + literal s.
+
+
val (^^) : ('a, 'b, 'c, 'd, 'e, 'f) format6 ->
       ('f, 'b, 'c, 'e, 'g, 'h) format6 -> ('a, 'b, 'c, 'd, 'g, 'h) format6
+f1 ^^ f2 catenates formats f1 and f2. The result is a format + that accepts arguments from f1, then arguments from f2.
+
+
+
Program termination

+
val exit : int -> 'a
+Terminate the process, returning the given status code + to the operating system: usually 0 to indicate no errors, + and a small positive integer to indicate failure. + All open output channels are flushed with flush_all. + An implicit exit 0 is performed each time a program + terminates normally. An implicit exit 2 is performed if the program + terminates early because of an uncaught exception.
+
+
val at_exit : (unit -> unit) -> unit
+Register the given function to be called at program + termination time. The functions registered with at_exit + will be called when the program executes exit, + or terminates, either normally or because of an uncaught exception. + The functions are called in ``last in, first out'' order: + the function most recently added with at_exit is called first.

6.1  Lexical conventions

Blanks

The following characters are considered as blanks: space, newline, +horizontal tabulation, carriage return, line feed and form feed. Blanks are +ignored, but they separate adjacent identifiers, literals and +keywords that would otherwise be confused as one single identifier, +literal or keyword.

Comments

Comments are introduced by the two characters (*, with no +intervening blanks, and terminated by the characters *), with +no intervening blanks. Comments are treated as blank characters. +Comments do not occur inside string or character literals. Nested +comments are handled correctly.

Identifiers

+
+ + +
+ident::= (letter∣ _) { letter∣ 0Â…9∣ _∣ ' }  
 
+letter::= A Â… Z ∣  a Â… z

Identifiers are sequences of letters, digits, _ (the underscore +character), and ’ (the single quote), starting with a +letter or an underscore. +Letters contain at least the 52 lowercase and uppercase +letters from the ASCII set. The current implementation +also recognizes as letters all accented characters from the ISO +8859-1 (“ISO Latin 1”) set. All characters in an identifier are +meaningful. The current implementation accepts identifiers up to +16000000 characters in length.

Integer literals

+
+ + + +
+integer-literal::= +[-] (0Â…9) { 0Â…9∣ _ } + 
 ∣ [-] (0x∣ 0X) (0Â…9∣ AÂ…F∣ aÂ…f) +{ 0Â…9∣ AÂ…F∣ aÂ…f∣ _ } + 
 ∣ [-] (0o∣ 0O) (0Â…7) { 0Â…7∣ _ } + 
 ∣ [-] (0b∣ 0B) (0Â…1) { 0Â…1∣ _ }

An integer literal is a sequence of one or more digits, optionally +preceded by a minus sign. By default, integer literals are in decimal +(radix 10). The following prefixes select a different radix: +

+ + + +
PrefixRadix
+0x, 0Xhexadecimal (radix 16)
0o, 0Ooctal (radix 8)
0b, 0Bbinary (radix 2)

+(The initial 0 is the digit zero; the O for octal is the letter O.) +The interpretation of integer literals that fall outside the range of +representable integer values is undefined.

For convenience and readability, underscore characters (_) are accepted +(and ignored) within integer literals.

Floating-point literals

+
+
+float-literal::= +[-] (0Â…9) { 0Â…9∣ _ } [. { 0Â…9∣ _ }] +[(e∣ E) [+∣ -] (0Â…9) { 0Â…9∣ _ }]

Floating-point decimals consist in an integer part, a decimal part and +an exponent part. The integer part is a sequence of one or more +digits, optionally preceded by a minus sign. The decimal part is a +decimal point followed by zero, one or more digits. +The exponent part is the character e or E followed by an +optional + or - sign, followed by one or more digits. +The decimal part or the exponent part can be omitted, but not both to +avoid ambiguity with integer literals. +The interpretation of floating-point literals that fall outside the +range of representable floating-point values is undefined.

For convenience and readability, underscore characters (_) are accepted +(and ignored) within floating-point literals.

Character literals

+

+
+ + + + + +
+char-literal::= +' regular-char ' + 
 ∣ ' escape-sequence ' + 
 
+escape-sequence::= +\ (\ ∣  " ∣  ' ∣  n ∣  t ∣  b ∣  r) + 
 ∣ \ (0Â…9) (0Â…9) (0Â…9) + 
 ∣ \x (0Â…9∣ AÂ…F∣ aÂ…f) +(0Â…9∣ AÂ…F∣ aÂ…f)

Character literals are delimited by Â’ (single quote) characters. +The two single quotes enclose either one character different from +Â’ and \, or one of the escape sequences below: +

+ + + + + + + + + + +
SequenceCharacter denoted
+\\backslash (\)
\"double quote (")
\Â’single quote (Â’)
\nlinefeed (LF)
\rcarriage return (CR)
\thorizontal tabulation (TAB)
\bbackspace (BS)
\spacespace (SPC)
\dddthe character with ASCII code ddd in decimal
\xhhthe character with ASCII code hh in hexadecimal

String literals

+

+
+ + + +
+string-literal::= +" { string-character } " + 
 
+string-character::= +regular-char-str + 
 ∣ escape-sequence

String literals are delimited by " (double quote) characters. +The two double quotes enclose a sequence of either characters +different from " and \, or escape sequences from the +table given above for character literals.

To allow splitting long string literals across lines, the sequence +\newline blanks (a \ at end-of-line followed by any +number of blanks at the beginning of the next line) is ignored inside +string literals.

The current implementation places practically no restrictions on the +length of string literals.

Naming labels

To avoid ambiguities, naming labels in expressions cannot just be defined +syntactically as the sequence of the three tokens ~, ident and +:, and have to be defined at the lexical level.

+
+ + + + +
+label-name ::= (a Â… z∣ _) { letter∣ 0Â…9∣ _∣ ' } 
 
+label ::= ~ label-name :  
 
+optlabel ::= ? label-name :

Naming labels come in two flavours: label for normal arguments and +optlabel for optional ones. They are simply distinguished by their +first character, either ~ or ?.

Despite label and optlabel being lexical entities in expressions, +their expansions ~ label-name : and ? label-name : will be +used in grammars, for the sake of readability. Note also that inside +type expressions, this expansion can be taken literally, i.e. +there are really 3 tokens, with optional spaces beween them.

Prefix and infix symbols

+
+ + + + + +
+infix-symbol::= +(= ∣  < ∣  > ∣  @ ∣  ^ ∣  | ∣  & ∣  ++ ∣  - ∣  * ∣  / ∣  $ ∣  %) { operator-char } + 
 
+prefix-symbol::= +(! ∣  ? ∣  ~) { operator-char } + 
 
+operator-char::= +! ∣  $ ∣  % ∣  & ∣  * ∣  + ∣  - ∣  . ∣  +/ ∣  : ∣  < ∣  = ∣  > ∣  ? ∣  @ ∣  +^ ∣  | ∣  ~ + 
 

Sequences of “operator characters”, such as <=> or !!, +are read as a single token from the infix-symbol or prefix-symbol +class. These symbols are parsed as prefix and infix operators inside +expressions, but otherwise behave much as identifiers. +

Keywords

The identifiers below are reserved as keywords, and cannot be employed +otherwise: +

      and         as          assert      asr         begin       class
+      constraint  do          done        downto      else        end
+      exception   external    false       for         fun         function
+      functor     if          in          include     inherit     initializer
+      land        lazy        let         lor         lsl         lsr
+      lxor        match       method      mod         module      mutable
+      new         object      of          open        or          private
+      rec         sig         struct      then        to          true
+      try         type        val         virtual     when        while
+      with        
+

The following character sequences are also keywords: +

    !=    #     &     &&    '     (     )     *     +     ,     -
+    -.    ->    .     ..    :     ::    :=    :>    ;     ;;    <
+    <-    =     >     >]    >}    ?     ??    [     [<    [>    [|
+    ]     _     `     {     {<    |     |]    }     ~
+

Note that the following identifiers are keywords of the Camlp4 +extensions and should be avoided for compatibility reasons. +

    parser    <<    <:    >>    $     $$    $:
+

Ambiguities

Lexical ambiguities are resolved according to the “longest match” +rule: when a character sequence can be decomposed into two tokens in +several different ways, the decomposition retained is the one with the +longest first token.

Line number directives

+
+ + +
+linenum-directive::= +# {0 Â… 9}+ + 
 ∣ # {0 Â… 9}+ " { string-character } " + 
 

Preprocessors that generate Caml source code can insert line number +directives in their output so that error messages produced by the +compiler contain line numbers and file names referring to the source +file before preprocessing, instead of after preprocessing. +A line number directive is composed of a # (sharp sign), followed by +a positive integer (the source line number), optionally followed by a +character string (the source file name). +Line number directives are treated as blank characters during lexical +analysis.
