g_irepository_get_default ()

GIRepository *
g_irepository_get_default (void);

Returns the singleton process-global default GIRepository. It is not currently supported to have multiple repositories in a particular process, but this function is provided in the unlikely eventuality that it would become possible, and as a convenience for higher level language bindings to conform to the GObject method call conventions.

All methods on GIRepository also accept NULL as an instance parameter to mean this default repository, which is usually more convenient for C.

g_irepository_get_dependencies ()

gchar **
g_irepository_get_dependencies (GIRepository *repository,
                                const gchar *namespace_);

Retrieves all (transitive) versioned dependencies for namespace_ .

The strings are of the form namespace-version.

Note: namespace_ must have already been loaded using a function such as g_irepository_require() before calling this function.

To get only the immediate dependencies for namespace_ , use g_irepository_get_immediate_dependencies().

g_irepository_get_immediate_dependencies ()

gchar **
g_irepository_get_immediate_dependencies
                               (GIRepository *repository,
                                const gchar *namespace_);

Return an array of the immediate versioned dependencies for namespace_ . Returned strings are of the form namespace-version.

Note: namespace_ must have already been loaded using a function such as g_irepository_require() before calling this function.

To get the transitive closure of dependencies for namespace_ , use g_irepository_get_dependencies().

g_irepository_get_loaded_namespaces ()

gchar **
g_irepository_get_loaded_namespaces (GIRepository *repository);

Return the list of currently loaded namespaces.

g_irepository_get_n_infos ()

gint
g_irepository_get_n_infos (GIRepository *repository,
                           const gchar *namespace_);

This function returns the number of metadata entries in given namespace namespace_ . The namespace must have already been loaded before calling this function.

g_irepository_get_info ()

GIBaseInfo *
g_irepository_get_info (GIRepository *repository,
                        const gchar *namespace_,
                        gint index);

This function returns a particular metadata entry in the given namespace namespace_ . The namespace must have already been loaded before calling this function. See g_irepository_get_n_infos() to find the maximum number of entries.

g_irepository_get_option_group ()

GOptionGroup *
g_irepository_get_option_group (void);

Obtain the option group for girepository, it's used by the dumper and for programs that wants to provide introspection information

g_irepository_enumerate_versions ()

GList *
g_irepository_enumerate_versions (GIRepository *repository,
                                  const gchar *namespace_);

Obtain an unordered list of versions (either currently loaded or available) for namespace_ in this repository .

g_irepository_prepend_library_path ()

void
g_irepository_prepend_library_path (const char *directory);

Prepends directory to the search path that is used to search shared libraries referenced by imported namespaces. Multiple calls to this function all contribute to the final list of paths. The list of paths is unique and shared for all GIRepository instances across the process, but it doesn't affect namespaces imported before the call.

If the library is not found in the directories configured in this way, loading will fall back to the system library path (ie. LD_LIBRARY_PATH and DT_RPATH in ELF systems). See the documentation of your dynamic linker for full details.

Since: 1.36

g_irepository_prepend_search_path ()

void
g_irepository_prepend_search_path (const char *directory);

Prepends directory to the typelib search path.

See also: g_irepository_get_search_path().

g_irepository_get_search_path ()

GSList *
g_irepository_get_search_path (void);

Returns the current search path GIRepository will use when loading typelib files. The list is internal to GIRepository and should not be freed, nor should its string elements.

g_irepository_load_typelib ()

const char *
g_irepository_load_typelib (GIRepository *repository,
                            GITypelib *typelib,
                            GIRepositoryLoadFlags flags,

g_irepository_get_typelib_path ()

const gchar *
g_irepository_get_typelib_path (GIRepository *repository,
                                const gchar *namespace_);

If namespace namespace_ is loaded, return the full path to the .typelib file it was loaded from. If the typelib for namespace namespace_ was included in a shared library, return the special string "<builtin>".

g_irepository_is_registered ()

gboolean
g_irepository_is_registered (GIRepository *repository,
                             const gchar *namespace_,
                             const gchar *version);

Check whether a particular namespace (and optionally, a specific version thereof) is currently loaded. This function is likely to only be useful in unusual circumstances; in order to act upon metadata in the namespace, you should call g_irepository_require() instead which will ensure the namespace is loaded, and return as quickly as this function will if it has already been loaded.

g_irepository_require ()

GITypelib *
g_irepository_require (GIRepository *repository,
                       const gchar *namespace_,
                       const gchar *version,
                       GIRepositoryLoadFlags flags,
                       GError **error);

Force the namespace namespace_ to be loaded if it isn't already. If namespace_ is not loaded, this function will search for a ".typelib" file using the repository search path. In addition, a version version of namespace may be specified. If version is not specified, the latest will be used.

g_irepository_require_private ()

GITypelib *
g_irepository_require_private (GIRepository *repository,
                               const gchar *typelib_dir,
                               const gchar *namespace_,
                               const gchar *version,
                               GIRepositoryLoadFlags flags,
                               GError **error);

Force the namespace namespace_ to be loaded if it isn't already. If namespace_ is not loaded, this function will search for a ".typelib" file within the private directory only. In addition, a version version of namespace should be specified. If version is not specified, the latest will be used.

g_irepository_get_c_prefix ()

const gchar *
g_irepository_get_c_prefix (GIRepository *repository,
                            const gchar *namespace_);

This function returns the "C prefix", or the C level namespace associated with the given introspection namespace. Each C symbol starts with this prefix, as well each GType in the library.

Note: The namespace must have already been loaded using a function such as g_irepository_require() before calling this function.

g_irepository_get_shared_library ()

const gchar *
g_irepository_get_shared_library (GIRepository *repository,
                                  const gchar *namespace_);

This function returns a comma-separated list of paths to the shared C libraries associated with the given namespace namespace_ . There may be no shared library path associated, in which case this function will return NULL.

Note: The namespace must have already been loaded using a function such as g_irepository_require() before calling this function.

g_irepository_get_version ()

const gchar *
g_irepository_get_version (GIRepository *repository,
                           const gchar *namespace_);

This function returns the loaded version associated with the given namespace namespace_ .

Note: The namespace must have already been loaded using a function such as g_irepository_require() before calling this function.

g_irepository_find_by_gtype ()

GIBaseInfo *
g_irepository_find_by_gtype (GIRepository *repository,
                             GType gtype);

Searches all loaded namespaces for a particular GType. Note that in order to locate the metadata, the namespace corresponding to the type must first have been loaded. There is currently no mechanism for determining the namespace which corresponds to an arbitrary GType - thus, this function will operate most reliably when you know the GType to originate from be from a loaded namespace.

g_irepository_find_by_error_domain ()

GIEnumInfo *
g_irepository_find_by_error_domain (GIRepository *repository,
                                    GQuark domain);

Searches for the enum type corresponding to the given GError domain. Before calling this function for a particular namespace, you must call g_irepository_require() once to load the namespace, or otherwise ensure the namespace has already been loaded.

Since: 1.30

g_irepository_find_by_name ()

GIBaseInfo *
g_irepository_find_by_name (GIRepository *repository,
                            const gchar *namespace_,
                            const gchar *name);

Searches for a particular entry in a namespace. Before calling this function for a particular namespace, you must call g_irepository_require() once to load the namespace, or otherwise ensure the namespace has already been loaded.

g_irepository_get_object_gtype_interfaces ()

void
g_irepository_get_object_gtype_interfaces
                               (GIRepository *repository,
                                GType gtype,
                                guint *n_interfaces_out,
                                GIInterfaceInfo ***interfaces_out);

Look up the implemented interfaces for gtype . This function cannot fail per se; but for a totally "unknown" GType, it may return 0 implemented interfaces.

The semantics of this function are designed for a dynamic binding, where in certain cases (such as a function which returns an interface which may have "hidden" implementation classes), not all data may be statically known, and will have to be determined from the GType of the object. An example is g_file_new_for_path() returning a concrete class of GLocalFile, which is a GType we see at runtime, but not statically.

Since: 1.62

g_irepository_dump ()

gboolean
g_irepository_dump (const char *arg,
                    GError **error);

Dump the introspection data from the types specified in input_filename to output_filename .

The input file should be a UTF-8 Unix-line-ending text file, with each line containing either get-type: followed by the name of a [typeGObject.Type ] _get_type function, or error-quark: followed by the name of an error quark function. No extra whitespace is allowed.

This function will overwrite the contents of the output file.
