NAME¶

h2paspp - Free Pascal h2pas preprocessor program.

SYNOPSIS¶

h2paspp [-doih] file1 ... filen

DESCRIPTION¶

h2paspp reads one or more C header files and preprocesses them, writing the result to files with the same name as the originals as it goes along. It does not accept all preprocesser tokens of C, but takes care of the following preprocessor directives:

#define symbol

Defines the new symbol symbol. Note that macros are not supported.

#if symbol

The text following this directive is included if symbol is defined.

#ifdef symbol

The text following this directive is included if symbol is defined.

#ifndef symbol

The text following this directive is included if symbol is not defined.

#include filename

Include directives are removed, unless the -I option was given, in which case the include file is included and written to the output file.

#undef symbol

The symbol symbol is undefined.

USAGE¶

h2paspp accepts one or more filenames and preprocesses them. It will read the input, and write output to a file with the same name unless the -o option is given, in which case the file is written to the specified file. Note that only one output filename can be given.

OPTIONS¶

h2paspp has a small number of options to control its behaviour:

-dsymbol

Define the symbol symbol before processing is started.

-h

emit a small helptext.

-ooutfile

If this option is given, the output will be written to a file named outfile. Note that only one output file can be given.
