Ppxlib - Meta-programming for OCaml

Ppxlib documentation

Overview

Ppxlib is the standard library for ppx rewriters and other programs that manipulate the in-memory representation of OCaml programs, a.k.a the "Parsetree".

It also comes bundled with two ppx rewriters that are commonly used to write tools that manipulate and/or generate Parsetree values; ppxlib.metaquot which allows to construct Parsetree values using the OCaml syntax directly and ppxlib.traverse which provides various ways of automatically traversing values of a given type, in particular allowing to inject a complex structured value into generated code.

For more information about ppxlib and how to use it, please consult the documentation.
