declare name context pattern expander
declares the extension names name
for
context
.
expander
is responsible for producing the code to replace the extension in the
AST. It receives as argument:
loc
: the location of the enclosing node. For instance for expression it is the
pexp_loc
fieldpath
: the current module pathval declare_with_path_arg : Ppxlib__.Import.string ‑> 'context Context.t ‑> (Ppxlib__.Import.payload, 'a, 'context) Ast_pattern.t ‑> (loc:Location.t ‑> path:Ppxlib__.Import.string ‑> arg:Longident.t Ppxlib__.Import.Asttypes.loc Ppxlib__.Import.option ‑> 'a) ‑> t
Same as declare
except that the extension name takes an additional path
argument. The path is the part of the name that start with a capitalized
component. For instance in the following, the extension "map"
would receive the path
argument Foo.Bar
:
let%map.Foo.Bar x = 1 in

Inline the result of the expansion into its parent. Only works for these contexts:
class_field
class_type_field
signature_item
structure_item

Given a context and a list of extension expander, returns all the ones that are for this context.
