ppx_drivers

This package implements a generic ppx driver to be used with OCaml "-ppx" command-line flag. This driver dynamically loads other Parsetree rewriters which are supposed to be installed as findlib packages.

Rewriters to be applied can be specified either on the command-line or directly in the source code. Each rewriter is specified as the name of its findlib package and can be passed some extra arguments.

Command-line syntax:

ppx_driver [-v] pkg arg ... arg -- pkg arg ... arg -- ....

In-source syntax (as a top-level structure or signature item):

[%%load_ppx "pkg" "arg" ... "arg"]
