#initialize(target_filename, files, g_type_prefix, include_files, options) ⇒ MkEnums

Initialize GLib::MkEnums

  • target_filename: the target file name. This creates #GLib::MkEnums.target_filenametarget_filename.c and #GLib::MkEnums.target_filenametarget_filename.h.

  • files: header files to parse

  • g_type_prefix: the gtype prefix such as GTK_TYPE_

  • include_files: define #include <file> lines into target_filename.c

Class Method Details

.create(target_filename, files, g_type_prefix, include_files, options) ⇒ Object
