Fully qualified names.

type t = name
include Core_kernel.Bin_prot.Binable.S with type t := t
include Ppx_sexp_conv_lib.Sexpable.S with type t := t
val t_of_sexp : Sexplib0.Sexp.t -> t
val sexp_of_t : t -> Sexplib0.Sexp.t
val create : ?package:string -> string -> t

create ?package name creates a fully qualified name.

The package and name strings can contain any characters all treated literally, e.g., the : character won't be treated as a separator neither it will break anything.

If package is not specified, then it defaults to the "user" package.

val read : ?package:string -> string -> t

read ?package input reads a full name from input.

This function will parse the input and return a fully-qualified name that corresponds to the input, using package as the currently opened package. The input syntax is

          name = string, ":", string
               | ":", string
               | string
          string = ?a sequence of any characters?

Not all characters in the input string are treated literally, the following two characters have a special interpretation:

  • '\\' the escape character;
  • ':' the package separator character.

The escape character disables a special interpretation of the consequent character. The package separator denotes the place in the input where the package name ends and the name part starts.

If package is specified then it is treated literally (as in the create function). The same as in create it defaults to the "user" package.

If input doesn't denote a fully qualified name (i.e., there is no ':' special character in input, then the read name is qualified with the passed package, otherwise the package is defined by the input.

The function is expected to work with the output of the show function, so that for all n, read (show n) = n. However, it is robust enough to accept any user inputs, even if it is not a well-formed input, e.g., when an escape character is used to escaped a non-special character or when input contains more than one unescaped separators. In case of invalid input, all special characters that doesn't make sense are treated literally and the first special ':' denotes the end of the package field. If the input is not valid, then it is possible that show (read s) <> s, since the output of show is always valid, e.g.

show@@read "hello:cruel:world" = "hello:cruel\\:world"

val show : t -> string

show name is the readable representation of name.

The name is represented as <package>:<name>, with all special characters escaped. See the read function for more information.

val unqualified : t -> string

unqualified name is the unqualified name.

Returns the name without the package specifier.

val package : t -> string

package name is the package of the name.

val str : unit -> t -> string

str () x = show x shows x.

This function is useful with printf-style functions that output to a string.

val hash : t -> int

hash name the name hash.

include Base.Comparable.S with type t := t

val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val bin_read_t : t Bin_prot.Read.reader
val __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.
