CPPO(1) General Commands Manual CPPO(1)NAME
cppo - cpp for OCaml.
SYNOPSIS
cppo [options] file*
DESCRIPTION
Cppo is an OCaml-friendly implementation of cpp, the C preprocessor. It can replace camlp4 for preprocessing OCaml files, using cpp style
and syntax. It allows defining simple macros and file inclusion.
OPTIONS -D DEF Equivalent of interpreting `#define DEF' before processing the input
-U IDENT
Equivalent of interpreting `#undef IDENT' before processing the input
-I DIR Add directory DIR to the search path for included files
-o FILE
Output file
-q Identify and preserve camlp4 quotations
-s Output line directives pointing to the exact source location of each token, including those coming from the body of macro defini-
tions. This behavior is off by default.
-n Do not output any line directive other than those found in the input (overrides -s).
-version
Print the version of the program and exit.
-help|--help

CamlP4 - Pre-Processor-Pretty-Printer for Objective Caml
SYNOPSIS
camlp4 [load-options] [--] [other-options]
DESCRIPTION
Camlp4 is a Pre-Processor-Pretty-Printer for Objective Caml. It offers tools for syntax (Stream Parsers and Grammars) and the ability to
modify the concrete syntax of the language (Quotations, Syntax Extensions).
The Objective Caml compiler has a special option "-pp", allowing to call any preprocessor. If Camlp4 is used, the parsing is done (only
once) by Camlp4, and the Objective Caml compiler resumes the rest of the compilation (typing, code generation).
Camlp4 can parse normal OCaml concrete syntax or any other user-definable syntax. As an example, an alternative syntax is provided, named
Revised, because it tries to fix some problems of the original syntax.
Camlp4 can pretty print the normal OCaml concrete syntax or the revised one (Pretty-Printer). It is therefore always possible to have a
version of your sources compilable by the compiler Objective Caml without preprocessing.
Camlp4 can also serve as a Program Transformation tool, the user can supply transformations and apply them easily as a pre-processing task.
This is done with Filters.
