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.
