val flatten : t -> string list
val unflatten : string list -> t optionFor 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 -> tThis 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.
To print a longident, see Pprintast.longident, using
Format.asprintf to convert to a string.
