       glib-mkenums - C language enum description generation utility

       glib-mkenums [OPTION...] [FILE...]

       glib-mkenums is a small perl-script utility that parses C code to extract enum definitions
       and produces enum descriptions based on text templates specified by the user. Most
       frequently this script is used to produce C code that contains enum values as strings so
       programs can provide value name strings for introspection.

       glib-mkenums takes a list of valid C code files as input. The options specified control
       the text that is output, certain substitutions are performed on the text templates for
       keywords enclosed in @ characters.

   Production text substitutions
       Certain keywords enclosed in @ characters will be substituted in the emitted text. For the
       substitution examples of the keywords below, the following example enum definition is

	   typedef enum
	     PREFIX_THE_XVALUE	  = 1 << 3,
	   } PrefixTheXEnum;

	   The name of the enum currently being processed, enum names are assumed to be properly
	   namespaced and to use mixed capitalization to separate words (e.g. PrefixTheXEnum).

	   The enum name with words lowercase and word-separated by underscores (e.g.

	   The enum name with words uppercase and word-separated by underscores (e.g.

	   The enum name with words uppercase and word-separated by underscores, prefix stripped
	   (e.g. THE_XENUM).

	   The prefix of the enum name (e.g. PREFIX).

	   The enum value name currently being processed with words uppercase and word-separated
	   by underscores, this is the assumed literal notation of enum values in the C sources

	   A nick name for the enum value currently being processed, this is usually generated by
	   stripping common prefix words of all the enum values of the current enum, the words
	   are lowercase and underscores are substituted by a minus (e.g. the-xvalue).

	   The integer value for the enum value currently being processed. This is calculated by
	   using perl to attempt to evaluate the expression as it appears in the C source code.
	   If evaluation fails then glib-mkenums will exit with an error status, but this only
	   happens if @valuenum@ appears in your value production template. (Since: 2.26)

	   This is substituted either by "enum" or "flags", depending on whether the enum value
	   definitions contained bit-shift operators or not (e.g. flags).

	   The same as @type@ with the first letter capitalized (e.g. Flags).

	   The same as @type@ with all letters uppercased (e.g. FLAGS).

	   The name of the input file currently being processed (e.g. foo.h).

	   The base name of the input file currently being processed (e.g. foo.h). (Since: 2.22)

   Trigraph extensions
       Some C comments are treated specially in the parsed enum definitions, such comments start
       out with the trigraph sequence /*< and end with the trigraph sequence >*/. Per enum
       definition, the options "skip" and "flags" can be specified, to indicate this enum
       definition to be skipped, or for it to be treated as a flags definition, or to specify the
       common prefix to be stripped from all values to generate value nicknames, respectively.
       The "underscore_name" option can be used to specify the word separation used in the
       *_get_type() function. For instance, /*< underscore_name=gnome_vfs_uri_hide_options >*/.

       Per value definition, the options "skip" and "nick" are supported. The former causes the
       value to be skipped, and the latter can be used to specify the otherwise auto-generated
       nickname. Examples:

	   typedef enum /*< skip >*/
	   } PrefixThisEnumWillBeSkipped;
	   typedef enum /*< flags,prefix=PREFIX >*/
	     PREFIX_THE_ZEROTH_VALUE,	 /*< skip >*/
	     PREFIX_THE_THIRD_VALUE,	 /*< nick=the-last-value >*/
	   } PrefixTheFlagsEnum;

       --fhead TEXT
	   Put out TEXT prior to processing input files.

       --fprod TEXT
	   Put out TEXT everytime a new input file is being processed.

       --ftail TEXT
	   Put out TEXT after all input files have been processed.

       --eprod TEXT
	   Put out TEXT everytime an enum is encountered in the input files.

       --vhead TEXT
	   Put out TEXT before iterating over the set of values of an enum.

       --vprod TEXT
	   Put out TEXT for every value of an enum.

       --vtail TEXT
	   Put out TEXT after iterating over all values of an enum.

       --comments TEXT
	   Template for auto-generated comments, the default (for C code generations) is "/*
	   @comment@ */".

       --template FILE
	   Read templates from the given file. The templates are enclosed in specially-formatted
	   C comments

	       /*** BEGIN section ***/
	       /*** END section ***/

	   where section may be file-header, file-production, file-tail, enumeration-production,
	   value-header, value-production, value-tail or comment.

       --identifier-prefix PREFIX
	   Indicates what portion of the enum name should be intepreted as the prefix (eg, the
	   "Gtk" in "GtkDirectionType"). Normally this will be figured out automatically, but you
	   may need to override the default if your namespace is capitalized oddly.

       --symbol-prefix PREFIX
	   Indicates what prefix should be used to correspond to the identifier prefix in related
	   C function names (eg, the "gtk" in "gtk_direction_type_get_type". Equivalently, this
	   is the lowercase version of the prefix component of the enum value names (eg, the
	   "GTK" in "GTK_DIR_UP". The default value is the identifier prefix, converted to

	   Print brief help and exit.

	   Print version and exit.
