A general purpose single-header preprocessor library.

The following directives are currently supported:

• #define <word>
• #undef <word>
• #if <condition>
• #elif <condition>
• #else
• #endif
• #include (via set_include_callback)
• Other arbitrary directives (via set_command_callback)

static char* read_file(const char* path, size_t* out_size) { /* ... */ } int main() { // Read contents of file "SomeFile.txt" into "buffer" size_t size; char* buffer = read_file("SomeFile.txt", &size); // Create a preprocessor ccpp::processor p; // Add some definitions p.add_define("SOME_DEFINE"); // Begin processing p.process(buffer, size); // Dump output printf("%s\n", buffer); return 0; }

I couldn't find a good simple no-dependencies preprocessor library for general purpose use that was also permissively licensed, so I decided to make my own.

This was made primarily as a preprocessor for Openplanet's scripts.
