Module `Expansion_helpers.Quoter`Source

Generate expressions in a hygienic way.

The idea is that whenever we want to refer to an expression in generated code we first quote it. The result will be an identifier that is guaranteed to refer to the expression it was created from. This way it is impossible for quoted fragments to refer to newly introduced expressions.

For more information, see the section on quoting in the good practices section.

Sourcetype t

Sourceval create : unit -> t

Creates a quoter. A quoter guarantees to give names that do not clash with any other names used before

Source

val quote : 
  t ->
  Astlib.Ast_500.Parsetree.expression ->
  Astlib.Ast_500.Parsetree.expression

quote t e returns the expression that is safe to use in place of e in generated code

Source

val sanitize : 
  t ->
  Astlib.Ast_500.Parsetree.expression ->
  Astlib.Ast_500.Parsetree.expression

sanitize t e Returns e wrapped with bindings for all quoted expressions in the quoter t
