MCPP(1)
NAME
mcpp - Matsui CPP, an alternative C preprocessor
SYNOPSIS
mcpp [options] [<infile> [<outfile>]]
DESCRIPTION
mcpp is a C/C++ preprocessor with the highest conformance which implements C90, C99 and C++98. mcpp has plentiful diagnostics and many
#pragmas. It is useful to check portability of your program, and also
useful to debug complicated macro. This is a man-page for mcpp of compiler-independent-build.
OPTIONS
mcpp expects two file names as arguments, <infile> and <outfile>. If
not specified, <infile> defaults to standard input and <outfile>
defaults to standard output.
It takes the following options.
Commonly used options:
- -@MODE Specify preprocessing mode. MODE should be one of these 4:
- -@std
Standard conforming mode. (default)
- -@poststd, -@post
special 'post-Standard' mode.
- -@kr
K&R 1st mode.
- -@oldprep, -@old
"old_preprocessor" mode (i.e. "Reiser model" cpp).
- -C Output also comments.
- -D <macro>[=<value>]
Define <macro> as <value> (default:1).
- -D <macro(args)>[=<replace>]
Define <macro(args)> as <replace>.
- -e <encoding>
Change the default multi-byte character encoding to one of: euc_jp, gb2312, ksc5601, big5, sjis, iso2022_jp, utf8.
- -I <directory>
Add <directory> to the #include search list.
- -I- Unset system or site specific include directories.
- -j Do not output the source line in diagnostics.
- -M, -MM, -MD, -MMD, -MP, -MQ target, -MT target, -MF file
Output source file dependency line for makefile.
- -N Don't predefine any non-standard macros.
- -o <file>
Output to <file>.
- -P Don't output #line lines.
- -Q Output diagnostics to "mcpp.err" (default:stderr).
- -U <macro>
Undefine <macro>.
- -v Show version of mcpp.
- -W <level>
Set warning level to <level> (OR of {0,1,2,4,8,16}, default:1).
- -z Don't output the included file, only defining macros.
- Options available with -@std (default) or -@poststd options:
- -+ Process C++ source.
- -2 Enable digraphs.
- -h <n> Re-define the pre-defined macro __STDC_HOSTED__ as <n>.
- -S <n> Redefine __STDC__ to <n>, undefine old style macros.
- -V <n> Redefine __STDC_VERSION__ or __cplusplus to <n>.
C with -V199901L specifies C99 mode.
C++ with -V199901L specifies C99 compatible mode. - Options available with only -@std (default) option:
- -@compat
Expand recursive macro more than Standard.
- -3 Enable trigraphs.
- -K Embed macro annotations into comments.
- Options available with -@std (default), -@kr or -@oldprep options:
- -a Process "assembler" source.
PRAGMA
mcpp has the following #pragma directives.
- #pragma once
- Read the header file only once even if multiply #included.
- #pragma __setlocale( "encoding")
- Specify the multibyte character encoding to "encoding". See -e option for the encodings.
- #pragma MCPP put_defines
- Putout all the macro definitions currently valid.
- #pragma MCPP debug <args>
- Start to putout debugging informations.
<args> should be one or more of:
token expand macro_call path if expression memory getc - #pragma MCPP end_debug <args>
- Stop to putout debugging informations.
<args> are the same with 'debug'.
No argument specifies all arguments. - #pragma MCPP push_macro( "MACRO")
- Save the macro definition to the stack.
- #pragma MCPP pop_macro( "MACRO")
- Retrieve the macro definition from the stack.
- #pragma MCPP preprocess
- "Pre-preprocess" the following header files for mcpp.
- #pragma MCPP warning any message
- Putout warning "any message".
