Description

Ppxlib is the standard infrastructure 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.

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 constructing 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.

What is the relation between ppxlib and other ppx libraries?

The ppx world has a long and storied history, and if you look around, you may find other projects that offer functionalities similar to ppxlib. The following blog post gives a good overview of the various libraries that have been developed over time. At this point, ppxlib is considered the de facto library for writing ppx rewriters.

History of the project
