Method create

CompilerEnvironment.CPP CompilerEnvironment.CPP(string|void current_file, int|string|void charset, object|void handler, void|int compat_major, void|int compat_minor, void|int picky_cpp)
CompilerEnvironment.CPP CompilerEnvironment.CPP(mapping(string:mixed) options)

Description

Initialize the preprocessor.

Parameter options

If the first argument is a mapping, no other arguments may follow. Instead, they have to be given as members of the mapping (if wanted). The following members are then recognized:

"current_file" : string	Name of the current file. It is used for generating #line directives and for locating include files.
"charset" : int|string	Charset to use when processing data.
"handler" : object	Compilation handler.
"compat_major" : int	Sets the major pike version used for compat handling.
"compat_minor" : int	Sets the minor pike version used for compat handling.
"picky_cpp" : int	Generate more warnings.
"keep_comments" : int	This option keeps cpp() from removing comments. Useful in combination with the prefix feature below.
"prefix" : string	If a prefix is given, only prefixed directives will be processed. For example, if the prefix is "foo", then #foo_ifdef COND and foo___LINE__ would be processed, #ifdef COND and __LINE__ would not.
"predefines" : mapping(string:mixed)	Mapping of predefined macros in addition to those returned by CPP()->get_predefines().

Parameter current_file

If the current_file argument has not been specified, it will default to "-".

Parameter charset

Turn on automatic character set detection if 1, otherwise specifies the character set used by the input. Defaults to "ISO-10646".
