This is a collection of PPX rewriters, re-implementing those based on ppxliband other libraries, but instead based on Camlp5. Included is also a collectionof support libraries for writing new PPX rewriters. Included are:

pa_assert: ppx_assertpa_ppx.deriving, pa_ppx.deriving_plugins (enum, eq, fold, iter, make, map, ord, sexp, show, yojson):ppx_deriving, plugins, ppx_sexp_conv, ppx_deriving_yojsonpa_ppx.expect_test: ppx_expect_testpa_ppx.here: ppx_herepa_ppx.import: ppx_importpa_ppx.inline_test: ppx_inline_test

pa_ppx.undo_deriving: pa_ppx.deriving expands [@@deriving ...] into code; this rewriter undoes that.pa_ppx.unmatched_vala: expands to match-cases (support library for camlp5-based PPX rewriters)pa_ppx.hashrecons: support for writing AST rewriters that automatically fills in hash-consing boilerplatepa_dock: implements doc-comment extraction for camlp5 preprocessors

Many of the reimplementations in fact offer significant enhancedfunction, described in the pa_ppx documentation. In addition, thereis an extensive test-suite, much of it slightly modified versions ofthe tests for the respective PPX rewriters.
