This group contains powerful getopt replacement.

This replacement handles both short (-X) or long options (--ABC) options, with various actions supported, like storing one value and already converting to required type, counting number of occurrences, setting true or false values, show help, license, copyright and even support user-defined callbacks.

It is provided a set of C Pre Processor macros so definition is straightforward.

Values will be stored elsewhere indicated by an array of pointers to values, it is given in separate to parser description so you can use multiple values with the same parser.

Parameters:

parser	This parameter isn't in use.
desc	This parameter isn't in use.
str	Geometry value
data	This parameter isn't in use.
storage	Must be a pointer to `Eina_Rectangle` and will be used to store the four values passed in the given string.

Returns:: EINA_TRUE on success, EINA_FALSE on incorrect geometry value.

This is a helper function to be used with ECORE_GETOPT_CALLBACK_*().

callback_data value is ignored, you can safely use NULL.

Since :: 3.0

Parameters:

parser	This parameter isn't in use.
desc	This parameter isn't in use.
str	size value
data	This parameter isn't in use.
storage	Must be a pointer to `Eina_Rectangle` and will be used to store the two values passed in the given string and `0` in the x and y fields.

Returns:: EINA_TRUE on success, EINA_FALSE on incorrect size value.

callback_data value is ignored, you can safely use NULL.

Since :: 3.0

void ecore_getopt_help	(	FILE *	fp,
		const Ecore_Getopt *	info
	)

Shows nicely formatted help message for the given parser.

Parameters:

fp	The file the message will be printed on.
info	The structure containing information about command line options.

See also:: ecore_getopt_help_category()

Since :: 3.0

Eina_Bool ecore_getopt_help_category	(	FILE *	fp,
		const Ecore_Getopt *	info,
		const char *	category
	)

Shows help for a single category (along with program usage and description).

Parameters:

fp	The file the message will be printed on.
info	The structure containing information about command line options.
category	The category to print.

Returns:: EINA_TRUE when the category exists, EINA_FALSE otherwise.

Since :: 3.0

Eina_List* ecore_getopt_list_free ( Eina_List * list )

Utilities to free list and nodes allocated by ECORE_GETOPT_ACTION_APPEND.

Parameters:

list	Pointer to list to be freed.

Returns:: always NULL, so you can easily make your list head NULL.

Since :: 3.0

int ecore_getopt_parse	(	const Ecore_Getopt *	parser,
		Ecore_Getopt_Value *	values,
		int	argc,
		char **	argv
	)

Parses command line parameters.

Walks the command line parameters and parse them based on parser description, doing actions based on parser->descs->action, like showing help text, license, copyright, storing values in values and so on.

It is expected that values is of the same size than parser->descs, options that do not need a value it will be left untouched.

All values are expected to be initialized before use. Options with action ECORE_GETOPT_ACTION_STORE and non required arguments (others than ECORE_GETOPT_DESC_ARG_REQUIREMENT_YES), are expected to provide a value in def to be used.

The following actions will store 1 on value as a boolean (value->boolp) if it's not NULL to indicate these actions were executed:

ECORE_GETOPT_ACTION_HELP
ECORE_GETOPT_ACTION_VERSION
ECORE_GETOPT_ACTION_COPYRIGHT
ECORE_GETOPT_ACTION_LICENSE

Just ECORE_GETOPT_ACTION_APPEND will allocate memory and thus need to be freed. For consistency between all of appended subtypes, eina_list->data will contain an allocated memory with the value, that is, for ECORE_GETOPT_TYPE_STR it will contain a copy of the argument, ECORE_GETOPT_TYPE_INT a pointer to an allocated integer and so on.

If parser is in strict mode (see Ecore_Getopt->strict), then any error will abort parsing and -1 is returned. Otherwise it will try to continue as far as possible.

This function may reorder argv elements.

Translation of help strings (description), metavar, usage, license and copyright may be translated, standard/global gettext() call will be applied on them if ecore was compiled with such support.

This function will not parse positional arguments! If these are declared (metavar is defined with both shortname and longname being empty), then you must call ecore_getopt_parse_positional() with the last argument (start) being the result of this function. This is done so you can have "quit options", those that once called you want to exit without doing further parsing, as is the case with help, license, copyright, version and eventually others you may define.

Parameters:

parser	Description of how to work.
values	Where to store values, it is assumed that this is a vector of the same size as `parser->descs`. Values should be previously initialized.
argc	How many elements in argv. If not provided it will be retrieved with ecore_app_args_get().
argv	Command line parameters.

Returns:: Index of first non-option parameter or -1 on error.

See also:: ecore_getopt_parse_positional()

Since :: 3.0

Examples:: ecore_thread_example.c.

int ecore_getopt_parse_positional	(	const Ecore_Getopt *	parser,
		Ecore_Getopt_Value *	values,
		int	argc,
		char **	argv,
		int	start
	)

Parses command line positional parameters.

Walks the command line positional parameters (those that do not start with "-" or "--") and parse them based on parser description, doing actions based on parser->descs->action, like storing values of some type.

It is expected that values is of the same size than parser->descs, same as with ecore_getopt_parse().

All values are expected to be initialized before use.

Unlike the ecore_getopt_parse(), only the following options are supported:

ECORE_GETOPT_ACTION_STORE
ECORE_GETOPT_ACTION_CHOICE
ECORE_GETOPT_ACTION_APPEND
ECORE_GETOPT_ACTION_CALLBACK

There is a special case for ECORE_GETOPT_ACTION_APPEND as it will consume all remaining elements. It is also special in the sense that it will allocate memory and thus need to be freed. For consistency between all of appended subtypes, eina_list->data will contain an allocated memory with the value, that is, for ECORE_GETOPT_TYPE_STR it will contain a copy of the argument, ECORE_GETOPT_TYPE_INT a pointer to an allocated integer and so on.

If parser is in strict mode (see Ecore_Getopt->strict), then any error will abort parsing and -1 is returned. Otherwise it will try to continue as far as possible.

Translation of help strings (description) and metavar may be done, standard/global gettext() call will be applied on them if ecore was compiled with such support.

Parameters:

parser	Description of how to work.
values	Where to store values, it is assumed that this is a vector of the same size as `parser->descs`. Values should be previously initialized.
argc	How many elements in argv. If not provided it will be retrieved with ecore_app_args_get().
argv	Command line parameters.
start	The initial position argument to look at, usually the return of ecore_getopt_parse(). If less than 1, will try to find it automatically.

Returns:: Index of first non-option parameter or -1 on error. If the last positional argument is of action ECORE_GETOPT_ACTION_APPEND then it will be the same as argc.

Since :: 3.0

Eina_Bool ecore_getopt_parser_has_duplicates ( const Ecore_Getopt * parser )

Checks parser for duplicate entries, print them out.

Returns:: EINA_TRUE if there are duplicates, EINA_FALSE otherwise.

Parameters:

parser The parser to be checked.

Since :: 3.0
