ppx_tools

Tools for authors of syntactic tools (such as ppx rewriters).

This package is licensed by LexiFi under the terms of the MIT license.

The tools are installed as a findlib package called 'ppx_tools'. Executables are thus accessible through the ocamlfind driver (e.g.: ocamlfind ppx_tools/dumpast).

ppx_metaquot

A ppx filter to help writing programs which manipulate the Parsetree, by allowing the programmer to use concrete syntax for expressions creating Parsetree fragments and patterns deconstructing Parsetree fragments. See the top of ppx_metaquot.ml for a description of the supported extensions.

Usage:

ocamlfind ocamlc -c -package ppx_tools.metaquot my_ppx_code.ml

Ast_mapper_class

This module implements an API similar to Ast_mapper from the compiler-libs, i.e. a generic mapper from Parsetree to Parsetree implemeting a deep identity copy, which can be customized with a custom behavior for each syntactic category. The difference with Ast_mapper is that Ast_mapper_class implements the open recursion using a class.
