It does not - do zip as a zip itself has more complexity than is needed, and it was much - simpler to implement this once here. - - Eet is extremely fast, small and simple. Eet files can be very small and - highly compressed, making them very optimal for just sending across the - internet without having to archive, compress or decompress and install them. - They allow for lightning-fast random-access reads once created, making them - perfect for storing data that is written once (or rarely) and read many - times, but the program does not want to have to read it all in at once. - - It also can encode and decode data structures in memory, as well as image - data for saving to Eet files or sending across the network to other - machines, or just writing to arbitrary files on the system. All data is - encoded in a platform independent way and can be written and read by any - architecture. - - @section example A simple example on using Eet - - Here is a simple example on how to use Eet to save a series of strings to a - file and load them again. The advantage of using Eet over just - fprintf() and - fscanf() is that not only can these entries be strings, they need no special - parsing to handle delimiter characters or escaping, they can be binary data, - image data, data structures containing integers, strings, other data - structures, linked lists and much more, without the programmer having to - worry about parsing, and best of all, Eet is very fast. - - This is just a very simple example that doesn't show all of the capabilities - of Eet, but it serves to illustrate its simplicity. - - @include eet-basic.c - - @section compiling How to compile using Eet ? - - Eet is a library your application links to. The procedure for this is very - simple. You simply have to compile your application with the appropriate - compiler flags that the @p pkg-config script outputs. For example: - - Compiling C or C++ files into object files: - - @verbatim - gcc -c -o main.o main.c `pkg-config --cflags eet` - @endverbatim - - Linking object files into a binary executable: - - @verbatim - gcc -o my_application main.o `pkg-config --libs eet` - @endverbatim - - You simply have to make sure that pkg-config is in your shell's PATH (see - the manual page for your appropriate shell) and eet.pc in /usr/lib/pkgconfig - or its path is in the PKG_CONFIG_PATH environment variable. It's that simple - to link and use Eet once you have written your code to use it. - - Since the program is linked to Eet, it is now able to use any advertised - API calls to serialize your data. - - You should make sure you add any extra compile and link flags to your - compile commands that your application may need as well. The above example - is only guaranteed to make Eet add it's own requirements. - - - @section install How is it installed? - - Simple: - - @verbatim - ./configure - make - su - - ... - make install - @endverbatim - - @section next_steps Next Steps - - After you understood what Eet is and installed it in your system you - should proceed understanding the programming interface. We'd recommend - you to take a while to learn Eina - (http://docs.enlightenment.org/auto/eina/) as it is very convenient - and optimized, and Eet provides integration with it. - - Recommended reading: - - @li @ref Eet_File_Group to know the basics to open and save files. - @li @ref Eet_Data_Group to know the convenient way to serialize and - parse your data structures automatically. Just create your - descriptors and let Eet do the work for you. - - @section intro_example Introductory Examples - - @ref Examples - - @todo Document data format for images and data structures. - - */ - -/** - @page authors Authors - @author Carsten Haitzler <raster@@rasterman.com> - @author David Goodlad <dgoodlad@@gmail.com> - @author Cedric Bail <cedric.bail@@free.fr> - @author Arnaud de Turckheim <quarium@@gmail.com> - @author Luis Felipe Strano Moraes <lfelipe@@profusion.mobi> - @author Chidambar Zinnoury <illogict@@online.fr> - @author Vincent Torri <vtorri@@univ-evry.fr> - @author Gustavo Sverzut Barbieri <barbieri@@profusion.mobi> - @author Raphael Kubo da Costa <kubo@@profusion.mobi> - @author Mathieu Taillefumier <mathieu.taillefumier@@free.fr> - @author Albin "Lutin" Tonnerre <albin.tonnerre@@gmail.com> - @author Adam Simpkins <adam@@adamsimpkins.net> - @author Mike Blumenkrantz <michael.blumenkrantz@gmail.com> - - Please contact <enlightenment-devel@lists.sourceforge.net> to get in - contact with the developers and maintainers. - */ - -#ifndef _EET_H -#define _EET_H - -#include <stdlib.h> -#include <stdio.h> -#include <Eina.h> - -#ifdef EAPI -# undef EAPI -#endif /* ifdef EAPI */ - -#ifdef _WIN32 -# ifdef EFL_EET_BUILD -# ifdef DLL_EXPORT -# define EAPI __declspec(dllexport) -# else /* ifdef DLL_EXPORT */ -# define EAPI -# endif /* !

For now, strings will suffice, - * so let's just dump a bunch of them in there. - * @until } - * - * As you can see, we copied a string into our static buffer, which is a bit - * bigger than the full length of the string, and then told Eet to write it - * into the file, compressed, returning the size of the data written into the - * file. - * This is all to show that Eet treats data as just data. It doesn't matter - * what that data represents (for now), it's all just bytes for it. As running - * the following code will show, we took a string of around 30 bytes and put it - * in a buffer of 1024 bytes, but the returned size won't be any of those. - * @until printf - * - * Next, we copy into our buffer our set of strings, including their null - * terminators and write them into the file. No error checking for the sake - * of brevity. And a call to eet_sync() to make sure all out data is - * properly written down to disk, even though we haven't yet closed the file. - * @until eet_sync - * - * One more write, this time our large array of binary data and... well, I - * couldn't come up with a valid use of the last set of strings we stored, - * so let's take it out from the file with eet_delete(). - * @until eet_delete - * - * Finally, we close the file, saving any changes back to disk and return. - * Notice how, if there's any error closing the file or saving its contents, - * the return value from the function will be a false one, which later on - * will make the program exit with an error code. - * @until return - * - * Moving onto our main function, we will open the same file and read it back. - * Trivial, but it'll show how we can do so in more than one way. We'll skip - * the variable declarations, as they aren't very different from what we've - * seen already. - * - * We start from the beginning by initializing Eet so things in general work. - * Forgetting to do so will result in weird results or crashes when calling - * any eet function, so if you experience something like that, the first thing - * to look at is whether eet_init() is missing. - * Then we call our @p create_eet_file function, described above, to make - * sure we have something to work with. If the function fails it will return - * 0 and we just exit, since nothing from here onwards will work anyway. - * @skip eet_init - * @until return - * - * Let's take a look now at what entries our file has. For this, we use - * eet_list(), which will return a list of strings, each being the name of - * one entry. Since we skipped before, it may be worth noting that @p list - * is declared as a @p char **. - * The @p num parameter will, of course, have the number of entries contained - * in our file. - * If everything's fine, we'll get our list and print it to the screen, and - * once done with it, we free the list. That's just the list, not its contents, - * as they are internal strings used by Eet and trying to free them will surely - * break things. - * @until } - * - * Reading back plain data is simple. Just a call to eet_read() with the file - * to read from, and the name of the entry we are interested in. We get back - * our data and the passed @p size parameter will contain the size of it. If - * the data was stored compressed, it will decompressed first. - * @until } - * - * Another simple read for the set of strings from before, except those were - * deleted, so we should get a NULL return and continue normally. - * @until } - * - * Finally, we'll get our binary data in the same way we got the strings. Once - * again, it makes no difference for Eet what the data is, it's up to us to - * know how to handle it. - * @until { - * - * Now some cheating, we know that this data is an Eet file because, well... - * we just know it. So we are going to open it and take a look at its insides. - * For this, eet_open() won't work, as it needs to have a file on disk to read - * from and all we have is some data in RAM. - * - * So how do we do? One way would be to create a normal file and write down - * our data, then open it with eet_open(). Another, faster and more efficient - * if all we want to do is read the file, is to use eet_memopen_read(). - * @until memopen - * - * As you can see, the size we got from our previous read was put to good use - * this time. Unlike the first one where all we had were strings, the size - * of the data read only serves to demonstrate that we are reading back the - * entire size of our original @p buf variable. - * - * A little peeking to see how many entries the file has and to make an - * example of eet_num_entries() to get that number when we don't care about - * their names. - * @until printf - * - * More cheating follows. Just like we knew this was an Eet file, we also know - * what key to read from, and ontop of that we know that the data in it is not - * compressed. - * Knowing all this allows us to take some shortcuts. - * @until read_direct - * - * That's a direct print of our data, whatever that data is. We don't want - * to worry about having to free it later, so we just used eet_direct_read() - * to tell Eet to gives a pointer to the internal data in the file, without - * duplicating it. Since we said that data was not compressed, we shouldn't - * worry about printing garbage to the screen (and yes, we also know the data - * is yet another string). - * We also don't care about the size of the data as it was stored in the file, - * so we passed NULL as the size parameter. - * One very important note about this, however, is that we don't care about - * the size parameter because the data in the file contains the null - * terminator for the string. So when using Eet to store strings this way, - * it's very important to consider whether you will keep that final null - * byte, or to always get the size read and do the necessary checks and copies. - * It's up to the user and the particular use cases to decide how this will - * be done. - * - * With everything done, close this second file and free the data used to open - * it. And this is important, we can't free that data until we are done with - * the file, as Eet is using it. When opening with eet_memopen_read(), the data - * passed to it must be available for as long as the the file is open. - * @until } - * - * Finally, we close the first file, shutdown all internal resources used by - * Eet and leave our main function, thus terminating our program. - * @until return - * - * You can look at the full code of the example @ref eet-file.c "here". - * @{ - */ - -/** - * @enum _Eet_File_Mode - * Modes that a file can be opened. - */ -typedef enum _Eet_File_Mode -{ - EET_FILE_MODE_INVALID = -1, - EET_FILE_MODE_READ, /**< File is read-only. */ - EET_FILE_MODE_WRITE, /**< File is write-only. */ - EET_FILE_MODE_READ_WRITE /**< File is for both read and write */ -} Eet_File_Mode; /**< Modes that a file can be opened. */ - -/** - * @typedef Eet_File - * Opaque handle that defines an Eet file (or memory). - * - * This handle will be returned by the functions eet_open() and - * eet_memopen_read() and is used by every other function that affects the - * file in any way.

It's all the same and if it makes - * more sense to keep them together, it's perfectly fine to do so. At the time - * of telling Eet how your data is comprised you can leave out the things - * that are runtime only and let Eet take care of the rest for you. - * - * The key used to store the config follows, as well as the variable used to - * store our data descriptor. - * This last one is very important. It's the one thing that Eet will use to - * identify your data, both at the time of writing it to the file and when - * loading from it. - * @skipline MY_CONF - * @skipline Eet_Data_Descriptor - * - * Now we'll see how to create this descriptor, so Eet knows how to handle - * our data later on. - * Begin our function by declaring an Eet_Data_Descriptor_Class, which is - * used to create the actual descriptor. This class contains the name of - * our data type, its size and several functions that dictate how Eet should - * handle memory to allocate the necessary bits to bring our data to life. - * You, as a user, will very hardly set this class' contents directly. The - * most common scenario is to use one of the provided macros that set it using - * the Eina data types, so that's what we'll be doing across all our examples. - * @skip static void - * @until eet_data_descriptor_stream_new - * - * Now that we have our descriptor, we need to make it describe something. - * We do so by telling it which members of our struct we want it to know about - * and their types. - * The eet_data_descriptor_element_add() function takes care of this, but it's - * too cumbersome for normal use, so several macros are provided that make - * it easier to handle. Even with them, however, code can get very repetitive - * and it's not uncommon to define custom macros using them to save on typing. - * @skip #define - * @until } - * - * Now our descriptor knows about the parts of our structure that we are - * interesting in saving. You can see that not all of them are there, yet Eet - * will find those that need saving and do the right thing. When loading our - * data, any non-described fields in the structure will be zeroed, so there's - * no need to worry about garbage memory in them. - * Refer to the documentation of #EET_DATA_DESCRIPTOR_ADD_BASIC to understand - * what our macro does. - * - * We are done with our descriptor init function and it's proper to have the - * relevant shutdown. Proper coding guidelines indiciate that all memory - * allocated should be freed when the program ends, and since you will most - * likely keep your descriptor around for the life or your application, it's - * only right to free it at the end. - * @skip static void - * @until } - * - * Not listed here, but included in the full example are functions to create - * a blank configuration and free it. The first one will only be used when - * no file exists to load from, or nothing is found in it, but the latter is - * used regardless of where our data comes from. Unless you are reading direct - * data from the Eet file, you will be in charge of freeing anything loaded - * from it. - * - * Now it's time to look at how we can load our config from some file. - * Begin by opening the Eet file normally. - * @skip static My_Conf_Type - * @until } - * - * And now we need to read the data from the file and decode it using our - * descriptor. Fortunately, that's all done in one single step. - * @until goto - * - * And that's it for all Eet cares about.

When we talk about nested - * structures, what we really want are things like lists and hashes to be - * taken into consideration automatically, and all their contents saved and - * loaded just like ordinary integers and strings are. - * - * And of course, Eet can do that, and considering the work it saves you as a - * programmer, we could say it's even easier to do than handling just integers. - * - * Let's begin with our example then, which is not all too different from the - * simple one introduced earlier. - * - * We won't ignore the headers this time to show how easy it is to use Eina - * data types with Eet, but we'll still skip most of the code that is not - * pertinent to what we want to show now, but as usual, you can get it full - * by following @ref eet-data-nested.c "this link". - * - * @dontinclude eet-data-nested.c - * @skipline Eina.h - * @skipline Eet.h - * @skip typedef struct - * @until } My_Conf_Subtype - * - * Extremely similar to our previous example. Just a new struct in there, and - * a pointer to a list in the one we already had. Handling a list of subtypes - * is easy on our program, but now we'll see what Eet needs to work with them - * (Hint: it's easy too). - * @skip _my_conf_descriptor - * @until _my_conf_sub_descriptor - * - * Since we have two structures now, it's only natural that we'll need two - * descriptors. One for each, which will be defined exactly as before. - * @skip static void - * @until eddc - * @skip EET_EINA_STREAM_DATA_DESCRIPTOR_CLASS_SET - * @until _my_conf_sub_descriptor - * - * We create our descriptors, each for one type, and as before, we are going to - * use a simple macro to set their contents, to save on typing. - * @skip #define - * @until EET_T_UCHAR - * - * So far, nothing new. We have our descriptors and we know already how to - * save them separately. But what we want is to link them together, and even - * more so, we want our main type to hold a list of more than one of the new - * sub type. So how do we do that? - * - * Simple enough, we tell Eet that our main descriptor will hold a list, of - * which each node will point to some type described by our new descriptor. - * @skip EET_DATA_DESCRIPTOR_ADD_LIST - * @until _my_conf_sub_descriptor - * - * And that's all. We are closing the function now so as to not leave dangling - * curly braces, but there's nothing more to show in this example. Only other - * additions are the necessary code to free our new data, but you can see it - * in the full code listing. - * @until } - */ - -/** - * @page eet_data_file_descriptor Advanced use of Eet Data Descriptors - * - * A real life example is usually the best way to see how things are used, - * but they also involve a lot more code than what needs to be shown, so - * instead of going that way, we'll be borrowing some pieces from one in - * the following example. It's been slightly modified from the original - * source to show more of the varied ways in which Eet can handle our data. - * - * @ref eet-data-file_descriptor_01.c "This example" shows a cache of user - * accounts and messages received, and it's a bit more interactive than - * previous examples. - * - * Let's begin by looking at the structures we'll be using. First we have - * one to define the messages the user receives and one for the one he posts. - * Straight forward and nothing new here. - * @dontinclude eet-data-file_descriptor_01.c - * @skip typedef - * @until My_Post - * - * One more to declare the account itself. This one will contain a list of - * all messages received, and the posts we make ourselves will be kept in an - * array. No special reason other than to show how to use arrays with Eet. - * @until My_Account - * - * Finally, the main structure to hold our cache of accounts. We'll be looking - * for these accounts by their names, so let's keep them in a hash, using - * that name as the key. - * @until My_Cache - * - * As explained before, we need one descriptor for each struct we want Eet - * to handle, but this time we also want to keep around our Eet file and its - * string dictionary. You will see why in a moment. - * @skip Eet_Data_Descriptor - * @until _my_post_descriptor - * @skip Eet_File - * @until Eet_Dictionary - * - * The differences begin now. They aren't much, but we'll be creating our - * descriptors differently. Things can be added to our cache, but we won't - * be modifying the current contents, so we can consider the data read from - * it to be read-only, and thus allow Eet to save time and memory by not - * duplicating thins unnecessary. - * @skip static void - * @until _my_post_descriptor - * - * As the comment in the code explains, we are asking Eet to give us strings - * directly from the mapped file, which avoids having to load it in memory - * and data duplication. - * Of course, there are things to take into account when doing things this - * way, and they will be mentioned as we encounter those special cases. - * - * Next comes the actual description of our data, just like we did in the - * previous examples. - * @skip #define - * @until #undef - * @until #define - * @until #undef - * - * And the account struct's description doesn't add much new, but it's worth - * commenting on it. - * @skip #define - * @until _my_post_descriptor - * - * How to add a list we've seen before, but now we are also adding an array. - * There's nothing really special about it, but it's important to note that - * the EET_DATA_DESCRIPTOR_ADD_VAR_ARRAY is used to add arrays of variable - * length to a descriptor. That is, arrays just like the one we defined. - * Since there's no way in C to know how long they are, we need to keep - * track of the count ourselves and Eet needs to know how to do so as well. - * That's what the @p posts_count member of our struct is for. When adding - * our array member, this macro will look for another variable in the struct - * named just like the array, but with @p _count attached to the end. - * When saving our data, Eet will know how many elements the array contains - * by looking into this count variable. When loading back from a file, this - * variable will be set to the right number of elements. - * - * Another option for arrays is to use EET_DATA_DESCRIPTOR_ADD_ARRAY, which - * takes care of fixed sized arrays. - * For example, let's suppose that we want to keep track of only the last - * ten posts the user sent, and we declare our account struct as follows - * @code - * typedef struct - * { - * unsigned int id; - * const char *name; - * Eina_List *messages; - * My_Post posts[10]; - * } My_Account; - * @endcode - * Then we would add the array to our descriptor with - * @code - * EET_DATA_DESCRIPTOR_ADD_ARRAY(_my_account_descriptor, My_Account, "posts", - * posts, _my_post_descriptor); - * @endcode - * - * Notice how this time we don't have a @p posts_count variable in our struct. - * We could have it for the program to keep track of how many posts the - * array actually contains, but Eet no longer needs it. Being defined that - * way the array is already taking up all the memory needed for the ten - * elements, and it is possible in C to determine how much it is in code. - * When saving our data, Eet will just dump the entire memory blob into the - * file, regardless of how much of it is really used. So it's important to - * take into consideration this kind of things when defining your data types. - * Each has its uses, its advantages and disadvantages and it's up to you - * to decide which to use. - * - * Now, going back to our example, we have to finish adding our data to the - * descriptors. We are only missing the main one for the cache, which - * contains our hash of accounts. - * Unless you are using your own hash functions when setting the descriptor - * class, always use hashes with string type keys. - * @skip #define - * @until } - * - * If you remember, we told Eet not to duplicate memory when possible at the - * time of loading back our data. But this doesn't mean everything will be - * loaded straight from disk and we don't have to worry about freeing it. - * Data in the Eet file is compressed and encoded, so it still needs to be - * decoded and memory will be allocated to convert it back into something we - * can use. We also need to take care of anything we add in the current - * instance of the program. - * To summarize, any string we get from Eet is likely to be a pointer to the - * internal dictionary, and trying to free it will, in the best case, crash - * our application right away. - * - * So how do we know if we have to free a string? We check if it's part of - * the dictionary, and if it's not there we can be sure it's safe to get - * rid of it. - * @skip static void - * @skip } - * @skip static void - * @until } - * - * See how this is used when adding a new message to our cache. - * @skip static My_Message - * @until return msg - * @until free(msg) - * @until } - * - * Skipping all the utility functions used by our program (remember you can - * look at the full example @ref eet-data-file_descriptor_01.c "here") we get to - * our cache loading code. Nothing out of the ordinary at first, just the - * same old open file, read data using our main descriptor to decode it - * into something we can use and check version of loaded data and if it doesn't - * match, do something accordingly. - * @skip static My_Cache - * @until } - * @until } - * @until } - * - * Then comes the interesting part. Remember how we kept two more global - * variables with our descriptors? One of them we already used to check if - * it was right to free a string or not, but we didn't know where it came from. - * Loading our data straight from the mmapped file means that we can't close - * it until we are done using it, so we need to keep its handler around until - * then. It also means that any changes done to the file can, and will, - * invalidate all our pointers to the file backed data, so if we add something - * and save the file, we need to reload our cache. - * - * Thus our load function checks if we had an open file, if there is it gets - * closed and our variable is updated to the new handler. Then we get the - * string dictionary we use to check if a string is part of it or not. - * Updating any references to the cache data is up you as a programmer to - * handle properly, there's nothing Eet can do in this situation. - * @until } - * - * The save function doesn't have anything new, and all that's left after it - * is the main program, which doesn't really have anything of interest within - * the scope of what we are learning. - */ - -/** - * @addtogroup Eet_Data_Group - * @{ - */ -#define EET_T_UNKNOW 0 /**< Unknown data encoding type */ -#define EET_T_CHAR 1 /**< Data type: char */ -#define EET_T_SHORT 2 /**< Data type: short */ -#define EET_T_INT 3 /**< Data type: int */ -#define EET_T_LONG_LONG 4 /**< Data type: long long */ -#define EET_T_FLOAT 5 /**< Data type: float */ -#define EET_T_DOUBLE 6 /**< Data type: double */ -#define EET_T_UCHAR 7 /**< Data type: unsigned char */ -#define EET_T_USHORT 8 /**< Data type: unsigned short */ -#define EET_T_UINT 9 /**< Data type: unsigned int */ -#define EET_T_ULONG_LONG 10 /**< Data type: unsigned long long */ -#define EET_T_STRING 11 /**< Data type: char * */ -#define EET_T_INLINED_STRING 12 /**< Data type: char * (but compressed inside the resulting eet) */ -#define EET_T_NULL 13 /**< Data type: (void *) (only use it if you know why) */ -#define EET_T_F32P32 14 /**< Data type: fixed point 32.32 */ -#define EET_T_F16P16 15 /**< Data type: fixed point 16.16 */ -#define EET_T_F8P24 16 /**< Data type: fixed point 8.24 */ -#define EET_T_LAST 18 /**< Last data type */ - -#define EET_G_UNKNOWN 100 /**< Unknown group data encoding type */ -#define EET_G_ARRAY 101 /**< Fixed size array group type */ -#define EET_G_VAR_ARRAY 102 /**< Variable size array group type */ -#define EET_G_LIST 103 /**< Linked list group type */ -#define EET_G_HASH 104 /**< Hash table group type */ -#define EET_G_UNION 105 /**< Union group type */ -#define EET_G_VARIANT 106 /**< Selectable subtype group */ -#define EET_G_LAST 107 /**< Last group type */ - -#define EET_I_LIMIT 128 /**< Other type exist but are reserved for internal purpose. */ - -/** - * @typedef Eet_Data_Descriptor - * - * Opaque handle that have information on a type members. - * - * Descriptors are created using an #Eet_Data_Descriptor_Class, and they - * describe the contents of the structure that will be serialized by Eet. - * Not all members need be described by it, just those that should be handled - * by Eet.

-// MEMORY_USAGE :
-// Memory usage formula : N->2^N Bytes (examples : 10 -> 1KB; 12 -> 4KB ; 16 -> 64KB; 20 -> 1MB; etc.)
-// Increasing memory usage improves compression ratio
-// Reduced memory usage can improve speed, due to cache effect
-// Default value is 14, for 16KB, which nicely fits into Intel x86 L1 cache
-#define MEMORY_USAGE 14
-
-// NOTCOMPRESSIBLE_DETECTIONLEVEL :
-// Decreasing this value will make the algorithm skip faster data segments considered "incompressible"
-// This may decrease compression ratio dramatically, but will be faster on incompressible data
-// Increasing this value will make the algorithm search more before declaring a segment "incompressible"
-// This could improve compression a bit, but will be slower on incompressible data
-// The default value (6) is recommended
-#define NOTCOMPRESSIBLE_DETECTIONLEVEL 6
-
-// BIG_ENDIAN_NATIVE_BUT_INCOMPATIBLE :
-// This will provide a small boost to performance for big endian cpu, but the resulting compressed stream will be incompatible with little-endian CPU.
-// You can set this option to 1 in situations where data will remain within closed environment
-// This option is useless on Little_Endian CPU (such as x86)
