Method cpp

string cpp(string data, mapping|string|void current_file, int|string|void charset, object|void handler, void|int compat_major, void|int compat_minor, void|int picky_cpp)

Description

Run a string through the preprocessor.

Preprocesses the string data with Pike's builtin ANSI-C look-alike preprocessor. If the current_file argument has not been specified, it will default to "-". charset defaults to "ISO-10646".

If the second 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 recognized:

current_file : string

This option does not strip comments from the file. Useful in combination with the prefix feature.

charset : int|string
handler : object
compat_major : int
compat_minor : int
picky_cpp : int
keep_comments : int
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.
