Description

MidgardConfig class represents Midgard unified configuration file. Underlying configuration file representation is limited to GKeyFile. There are few ways to read configuration data: midgard_config_read_file(), which encapsulates real file location, midgard_config_read_file_at_path() if file location is not common or very specific for application or midgard_config_read_data(), which reads configuration from given buffer.

Details

MidgardConfig

typedef struct MidgardConfig MidgardConfig;

MidgardConfigClass

typedef struct MidgardConfigClass MidgardConfigClass;

MidgardConfigPrivate

typedef struct _MidgardConfigPrivate MidgardConfigPrivate;

enum MidgardDBType

typedef enum {
        MIDGARD_DB_TYPE_MYSQL = 1, 
        MIDGARD_DB_TYPE_POSTGRES, 
        MIDGARD_DB_TYPE_FREETDS, 
        MIDGARD_DB_TYPE_SQLITE, 
        MIDGARD_DB_TYPE_ODBC, 
        MIDGARD_DB_TYPE_ORACLE 
} MidgardDBType;

midgard_config_new ()

MidgardConfig *     midgard_config_new                  (void);

Initializes new instance of MidgardConfig object type. NULL is returned when object can not be initialized.

Returns :

 pointer to MidgardConfig object or NULL on failure.

midgard_config_read_file ()

gboolean            midgard_config_read_file            (MidgardConfig *self,
                                                         const gchar *filename,
                                                         gboolean user,
                                                         GError **error);

This method reads configuration file from the given name and sets MidgardConfig object's properties. Such initialized MidgardConfig instance may be reused among midgard-core and midgard-php extension for example, without any need to re-read configuration file and without any need to re-initalize MidgardConfig object instance.

Set TRUE as user boolean value to read files from user's home directory.

self :

 MidgardConfig object instance

filename :

 name of the file to read

user :

 boolean switch for system or user's config files

error :

 pointer to store error

Returns :

 TRUE when file has been read , FALSE otherwise.

Since 9.3

midgard_config_list_files ()

gchar **            midgard_config_list_files           (gboolean user);

List all available configuration files. If user value is set to TRUE, all available files from ~/.midgard/conf.d will be listed. Only system files ( usually from /etc/midgard/conf.d ) will be listed if user value is set to FALSE.

Returned array should be freed when no longer needed.
