## Detailed Description

This group discusses functions that have general purposes or affect Edje as a whole.

Besides containing the initialize and shutdown functions of the library, which should always be called when we are using Edje, this module contains some other utilities that could be used in many contexts or should do their jobs independent of the context inside Edje.

## Function Documentation

## ◆ edje_init()

int edje_init | ( | void |  | ) |

Initializes the Edje library.

Returns
  The new init count. The initial value is zero.

This function initializes the Edje library, making the proper calls to internal initialization functions. It will also initialize its dependencies, making calls to `eina_init()`, `ecore_init()`, `embryo_init()` and `eet_init()`. So, there is no need to call those functions again, in your code. To shutdown Edje there is the function edje_shutdown().

See also
  edje_shutdown()
  eina_init()
  ecore_init()
  embryo_init()
  eet_init()

Examples
  edje-basic.c, edje-box.c, edje-box2.c, edje-color-class.c, edje-drag.c, edje-perspective.c, edje-signals-messages.c, edje-swallow.c, edje-table.c, edje-text.c, emotion_test_main.c, and evas-aspect-hints.c.

## ◆ edje_shutdown()

int edje_shutdown | ( | void |  | ) |

Shuts down the Edje library.

Returns
  The number of times the library has been initialized without being shutdown.

This function shuts down the Edje library. It will also call the shutdown functions of its dependencies, which are `eina_shutdown()`, `ecore_shutdown()`, `embryo_shutdown()` and `eet_shutdown()`, so there is no need to call these functions again, in your code.

See also
  edje_init()
  eina_shutdown()
  ecore_shutdown()
  embryo_shutdown()
  eet_shutdown()

Examples
  edje-basic.c, edje-box.c, edje-box2.c, edje-color-class.c, edje-drag.c, edje-perspective.c, edje-signals-messages.c, edje-swallow.c, edje-table.c, edje-text.c, emotion_test_main.c, and evas-aspect-hints.c.

## ◆ edje_fontset_append_set()

void edje_fontset_append_set | ( | const char * | fonts | ) |

Sets the edje append fontset.

Parameters

  fonts | The fontset to append.

This function sets the edje append fontset.

References eina_str_escape().

## ◆ edje_mmap_data_get()

char * edje_mmap_data_get | ( | const Eina_File * | f,
|  | const char * | key
| ) |  |

Gets data from the file level data block of an edje mapped file.

Parameters

  f | The mapped edje file
  key | The data key

Returns
  The string value of the data, or `NULL` if no key is found. Must be freed by the user when no longer needed.

If an edje file test.edj is built from the following edc:

data { item: "key1" "value1"; item: "key2" "value2"; } collections { ... }

Then, edje_file_data_get("test.edj", "key1") will return "value1"

References eina_hash_find().

## ◆ edje_file_data_get()

char * edje_file_data_get | ( | const char * | file,
|  | const char * | key
| ) |  |

Gets data from the file level data block of an edje file.

Parameters

  file | The path to the .edj file
  key | The data key

Returns
  The string value of the data, or `NULL` if no key is found. Must be freed by the user when no longer needed.

If an edje file test.edj is built from the following edc:

data { item: "key1" "value1"; item: "key2" "value2"; } collections { ... }

Then, edje_file_data_get("test.edj", "key1") will return "value1"

## ◆ edje_module_load()

Eina_Bool edje_module_load | ( | const char * | module | ) |

Loads a new module in Edje.

Parameters

  module | The name of the module that will be added to Edje.

Returns
  `EINA_TRUE` if the module was successfully loaded. Otherwise, `EINA_FALSE`.

Modules are used to add functionality to Edje. So, when a module is loaded, its functionality should be available for use.

References EINA_FALSE, and EINA_TRUE.

## ◆ edje_available_modules_get()

const Eina_List * edje_available_modules_get | ( | void |  | ) |

Retrieves all modules that can be loaded.

Returns
  A list of all loadable modules.

This function retrieves all modules that can be loaded by edje_module_load().

See also
  edje_module_load().
