Documentation

       Module Longident
        : sig end

       Long identifiers, used in parsetree.

       Warning: this module is unstable and part of Compiler_libs .

       To print a longident, see Pprintast.longident , using Format.asprintf to convert to a string.

       type t =
        | Lident of string
        | Ldot of t * string
        | Lapply of t * t

       val flatten : t -> string list

       val unflatten : string list -> t option

       For  a  non-empty  list  l  ,  unflatten  l  is  Some  lid  where  lid  is the long identifier created by
       concatenating the elements of l with Ldot .  unflatten [] is None .

       val last : t -> string

       val parse : string -> t

       This function is broken on identifiers that are  not  just  "Word.Word.word";  for  example,  it  returns
       incorrect results on infix operators and extended module paths.

       If  you  want  to  generate  long  identifiers that are a list of dot-separated identifiers, the function
       Longident.unflatten is safer and faster.  Longident.unflatten is available since OCaml 4.06.0.

       If you want to parse any identifier correctly, use the long-identifiers functions from the Parse  module,
       in  particular  Parse.longident  .   They  are  available  since  OCaml  4.11,  and  also  provide proper
       input-location support.
