Standard library for ppx rewriters

ppxlib is meant to be opened globally in your PPX source files.

Opening it comes with two advantages. First, it will shadow the compiler-libs modules. The compiler-libs modules are unstable and aren't meant to be used, so shadowing them is a good protection mechanism. In case you don't want to open Ppxlib, you can open Ocaml_shadow to get the same protection. Second, it will bring several modules in scope, that are useful to have when writing a rewriter:

  • The main ppxlib modules, such as modules to help manipulate the AST (Ast_builder, Ast_pattern), and a few functions.
  • Modules from other libraries, such as Ast_helper or Pprintast,
  • The whole AST types (by including the Ast module).

The core ppxlib entries

Manipulating the AST

module Ast_builder : sig ... end

Ast_builder is a module to generate OCaml AST fragments. It provides a shorter syntax than directly using the Parsetree constructors, as well as a better stability than the constructors.

module Ast_pattern : sig ... end

This module implements first class AST patterns. It allows to destruct and extract values from AST fragments. This gives the same functionality as a pattern-match, but with simpler syntax and more stability than directly pattern-matching on the Parsetree constructors.

module Ast_traverse : sig ... end

This module provides AST traversal classes, such as maps, iterations, folds, etc. on the Parsetree types.

Context-free rewriting

module Context_free : sig ... end

Context free rewriting, to define local rewriting rules that will all be applied at once by the driver.

module Deriving : sig ... end

Deriving code from type declarations.

module Extension : sig ... end

Declare extenders to rewrite extension nodes.

module Expansion_context : sig ... end

The context given to rewriting rules when expanding.

module Code_path : sig ... end

This module contains type and functions for representing and manipulating path to AST nodes.

Other helpers

module Expansion_helpers : sig ... end

Various helpers for expansion, such as quoting expressions in their context, or mangling names.

module Merlin_helpers : sig ... end

Some helpers to annotate the AST so merlin can decide which branches to look at and which branches to ignore.

module Spellcheck : sig ... end

Helpers to provide hints to PPX users for typos or spellchecks.

module Keyword : sig ... end

Small module to check if a string is an OCaml keyword.

module Pp_ast : sig ... end

This module implements pretty printers for the OCaml AST's version used by ppxlib.

module Driver : sig ... end

Interaction with the driver, such as getting/seeting cookies, adding arguments.

module Caller_id : sig ... end

Small helper to find out who is the caller of a function

module Ast_io : sig ... end

A small module to help read bin-annots generated files.

Checks

module Attribute : sig ... end

This module provides hygiene for attributes. The goal is to report misuses of attributes to the user as soon as possible so that no mistyped attribute get silently ignored.

module Reserved_namespaces : sig ... end

Small module to reserve namespaces in attribute names.

Common helper functions

val lident : string -> Longident.t
val gen_symbol : ?prefix:string -> unit -> string

gen_symbol ?prefix () generates a fresh variable name with prefix.

  • parameter prefix

    default = "_x"

val string_of_core_type : Astlib.Ast_500.Parsetree.core_type -> string
val assert_no_attributes : Astlib.Ast_500.Parsetree.attribute list -> unit
val assert_no_attributes_in : Ppxlib__.Ast_traverse0.iter
val attributes_errors : Astlib.Ast_500.Parsetree.attribute list -> Location.Error.t list
val collect_attributes_errors : Location.Error.t list Ppxlib__.Ast_traverse0.fold

get_type_param_name_res tp returns the string identifier associated with tp if it is a type parameter, as a result.

See get_type_param_name_res. Raises a located error in case of failure.

(new type_is_recursive rec_flag tds)#go () returns whether rec_flag, tds is really a recursive type. We disregard recursive occurrences appearing in arrow types. You can override the search for certain type expressions by inheriting from this class.

really_recursive rec_flag tds = (new type_is_recursive rec_flag tds)#go ()

convert multi-arg function applications into a cascade of 1-arg applications

val attribute_of_warning : Location.t -> string -> Astlib.Ast_500.Parsetree.attribute

Encode a warning message into an 'ocaml.ppwarning' attribute which can be inserted in a generated Parsetree. The compiler will be responsible for reporting the warning.

val is_polymorphic_variant : Astlib.Ast_500.Parsetree.type_declaration -> sig_:bool -> [> `Definitely | `Maybe | `Surely_not ]
val mk_named_sig : loc:Location.t -> sg_name:string -> handle_polymorphic_variant:bool -> Astlib.Ast_500.Parsetree.type_declaration list -> Astlib.Ast_500.Parsetree.module_type Astlib.Ast_500.Parsetree.include_infos option

mk_named_sig ~loc ~sg_name:"Foo" ~handle_polymorphic_variant tds will generate

include Foo (* or Foo1, Foo2, Foo3 *)
  with type (* ('a, 'b, 'c) *) t := (* ('a, 'b, 'c) *) t

when:

  • there is only one type declaration
  • the type is named t
  • there are less than 4 type parameters
  • there are no constraints on the type parameters

It will take care of giving fresh names to unnamed type parameters.

val exn_to_loc_error : exn -> Location.Error.t

Convert exn to a located error if possible or reraise it otherwise

module With_errors : sig ... end

Modules from other libraries

module Location : sig ... end

module Longident : sig ... end

Overrides the Longident module of OCaml

module Loc : sig ... end
