## Detailed Description

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.

## Function Documentation

## ◆ ecore_getopt_help()

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

Shows nicely formatted help message for the given parser.

Parameters

  info | The structure containing information about command line options.

See also
  ecore_getopt_help_category()

## ◆ ecore_getopt_help_category()

EAPI 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.

## ◆ ecore_getopt_parser_has_duplicates()

EAPI 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.

References _Ecore_Getopt::descs, EINA_FALSE, EINA_TRUE, _Ecore_Getopt_Desc::longname, and _Ecore_Getopt_Desc::shortname.

## ◆ ecore_getopt_parse()

EAPI 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()

References ecore_app_args_get(), _Ecore_Getopt_Desc::longname, _Ecore_Getopt::prog, and _Ecore_Getopt_Desc::shortname.

## ◆ ecore_getopt_parse_positional()

EAPI 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.

## ◆ ecore_getopt_list_free()

EAPI Eina_List * ecore_getopt_list_free | ( | Eina_List * | list | ) |

Parameters

  list | Pointer to list to be freed.

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

## ◆ ecore_getopt_callback_geometry_parse()

EAPI Eina_Bool ecore_getopt_callback_geometry_parse | ( | const Ecore_Getopt * | parser,
|  | const Ecore_Getopt_Desc * | desc,
|  | const char * | str,
|  | void * | data,
|  | Ecore_Getopt_Value * | storage

Parameters

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

`callback_data` value is ignored, you can safely use `NULL`.

## ◆ ecore_getopt_callback_size_parse()

EAPI Eina_Bool ecore_getopt_callback_size_parse | ( | const Ecore_Getopt * | parser,
|  | const Ecore_Getopt_Desc * | desc,
|  | const char * | str,
|  | void * | data,
|  | Ecore_Getopt_Value * | storage

Helper ecore_getopt callback to parse geometry size (WxH).

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.

`callback_data` value is ignored, you can safely use `NULL`.
