Module `Merlin_kernel.Overrides`Source

Decodes [@@@merlin] override attribute into a list and provides find to find an Override.t given a Lexing.position.

The general structure of a [@@@merlin] attribute is a list of records pairing a Location.t with a payload. The [@@@merlin.document] attribute can be used, for example, to override merlin's Document behavior.

The expected structure of a general [@@@merlin]'s payload is as follows: | [ { "location" = { "loc_start" = { pos_fname = "filename.ml"; pos_lnum = 1; pos_bol = 0; pos_cnum = 0 "loc_end" = pos_fname = "filename.ml"; pos_lnum = 1; pos_bol = 0; pos_cnum = 0 "loc_ghost" = false

}

, "payload" = <payload>

}

; ... ] |

}

Each individual element of the list is stored as an Override.t, and the full list is stored as a t.

val get_overrides : 
  attribute_name:'a Attribute_name.t ->
  Mreader.parsetree ->
  'a t

Constructs a t from a Mreader.parsetree. An error is returned on unexpected AST node structures and parsing errors.

If there are multiple @@@merlin.X attributes (of the same .X), they will be merged.

Sourceval find : 'a t -> cursor:Lexing.position -> 'a Override.t option

Finds the first Override.t that cursor is enclosed in.
