package ocaml-base-compiler
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.
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 unflatten
is safer and faster. 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.
