22 @section intro What is Eet?
23
24 It is a tiny library designed to write an arbitrary set of chunks of data
25 to a file and optionally compress each chunk (very much like a zip file)
26 and allow fast random-access reading of the file later on. It does not
27 do zip as a zip itself has more complexity than is needed, and it was much
28 simpler to implement this once here.
29
30 Eet is extremely fast, small and simple. Eet files can be very small and
31 highly compressed, making them very optimal for just sending across the
32 internet without having to archive, compress or decompress and install them.
33 They allow for lightning-fast random-acess reads once created, making them
34 perfect for storing data that is written once (or rarely) and read many
35 times, but the program does not want to have to read it all in at once.
36
37 It also can encode and decode data structures in memory, as well as image
38 data for saving to Eet files or sending across the network to other
39 machines, or just writing to arbitrary files on the system. All data is
40 encoded in a platform independent way and can be written and read by any
41 architecture.
42
43 @section example A simple example on using Eet
44
45 Here is a simple example on how to use Eet to save a series of strings to a
46 file and load them again. The advantage of using Eet over just
47 fprintf() and
48 fscanf() is that not only can these entries be strings, they need no special
49 parsing to handle delimiter characters or escaping, they can be binary data,
50 image data, data structures containing integers, strings, other data
51 structures, linked lists and much more, without the programmer having to
52 worry about parsing, and best of all, Eet is very fast.
53
54 This is just a very simple example that doesn't show all of the capabilities
55 of Eet, but it serves to illustrate its simplicity.
56
57 @include eet-basic.c
58
59 @section compiling How to compile using Eet ?
60
61 Eet is a library your application links to. The procedure for this is very
62 simple. You simply have to compile your application with the appropriate
63 compiler flags that the @p pkg-config script outputs. For example:
64
65 Compiling C or C++ files into object files:
66
67 @verbatim
68 gcc -c -o main.o main.c `pkg-config --cflags eet`
69 @endverbatim
70
71 Linking object files into a binary executable:
72
73 @verbatim
74 gcc -o my_application main.o `pkg-config --libs eet`
75 @endverbatim
76
77 You simply have to make sure that pkg-config is in your shell's PATH (see
78 the manual page for your appropriate shell) and eet.pc in /usr/lib/pkgconfig
79 or its path is in the PKG_CONFIG_PATH environment variable. It's that simple
80 to link and use Eet once you have written your code to use it.
81
82 Since the program is linked to Eet, it is now able to use any advertised
83 API calls to serialize your data.
84
85 You should make sure you add any extra compile and link flags to your
86 compile commands that your application may need as well. The above example
87 is only guaranteed to make Eet add it's own requirements.
88
89
90 @section install How is it installed?
91
92 Simple:
93
94 @verbatim
95 ./configure
96 make
97 su -
98 ...
99 make install
100 @endverbatim
101
102 @section next_steps Next Steps
103
104 After you understood what Eet is and installed it in your system you
105 should proceed understanding the programming interface. We'd recommend
106 you to take a while to learn Eina
107 (http://docs.enlightenment.org/auto/eina/) as it is very convenient
108 and optimized, and Eet provides integration with it.
109
110 Recommended reading:

112 @li @ref Eet_File_Group to know the basics to open and save files.
113 @li @ref Eet_Data_Group to know the convenient way to serialize and
114 parse your data structures automatically. Just create your
115 descriptors and let Eet do the work for you.

316 *
317 * Functions to create, destroy and do basic manipulation of
318 * #Eet_File handles.
319 *
320 * This sections explains how to use the most basic Eet functions, which
321 * are used to work with eet files, read data from them, store it back in or
322 * take a look at what entries it contains, without making use of the
323 * serialization capabilities explained in @ref Eet_Data_Group.
324 *
325 * The following example will serve as an introduction to most, if not all,
326 * of these functions.
327 *
328 * If you are only using Eet, this is the only header you need to include.
329 * @dontinclude eet-file.c
330 * @skipline Eet.h
331 *
332 * Now let's create ourselves an eet file to play with. The following function
333 * shows step by step how to open a file and write some data in it.
334 * First, we define our file handler and some other things we'll put in it.
335 * @line static int
336 * @skip Eet_File
337 * @until ";
338 * @skip eet_open
339 *
340 * We open a new file in write mode, and if it fails, we just return, since
341 * there's not much more we can do about it..
342 * @until return
343 *
344 * Now, we need to write some data in our file. For now, strings will suffice,
345 * so let's just dump a bunch of them in there.
346 * @until }
347 *
348 * As you can see, we copied a string into our static buffer, which is a bit
349 * bigger than the full length of the string, and then told Eet to write it
350 * into the file, compressed, returning the size of the data written into the
351 * file.
352 * This is all to show that Eet treats data as just data. It doesn't matter
353 * what that data represents (for now), it's all just bytes for it. As running
354 * the following code will show, we took a string of around 30 bytes and put it
355 * in a buffer of 1024 bytes, but the returned size won't be any of those.
356 * @until printf
357 *
358 * Next, we copy into our buffer our set of strings, including their null
359 * terminators and write them into the file. No error checking for the sake
360 * of brevitiy. And a call to eet_sync() to make sure all out data is
361 * properly written down to disk, even though we haven't yet closed the file.
362 * @until eet_sync
363 *
364 * One more write, this time our large array of binary data and... well, I
365 * couldn't come up with a valid use of the last set of strings we stored,
366 * so let's take it out from the file with eet_delete().
367 * @until eet_delete
368 *
369 * Finally, we close the file, saving any changes back to disk and return.
370 * Notice how, if there's any error closing the file or saving its contents,
371 * the return value from the function will be a false one, which later on
372 * will make the program exit with an error code.
373 * @until return
374 *
375 * Moving onto our main function, we will open the same file and read it back.
376 * Trivial, but it'll show how we can do so in more than one way. We'll skip
377 * the variable declarations, as they aren't very different from what we've
378 * seen already.
379 *
380 * We start from the beginning by initializing Eet so things in general work.
381 * Forgetting to do so will result in weird results or crashes when calling
382 * any eet function, so if you experience something like that, the first thing
383 * to look at is whether eet_init() is missing.
384 * Then we call our @p create_eet_file function, described above, to make
385 * sure we have something to work with. If the function fails it will return
386 * 0 and we just exit, since nothing from here onwards will work anyway.
387 * @skip eet_init
388 * @until return
389 *
390 * Let's take a look now at what entries our file has. For this, we use
391 * eet_list(), which will return a list of strings, each being the name of
392 * one entry. Since we skipped before, it may be worth noting that @p list
393 * is declared as a @p char **.
394 * The @p num parameter will, of course, have the number of entries contained
395 * in our file.
396 * If everything's fine, we'll get our list and print it to the screen, and
397 * once done with it, we free the list. That's just the list, not its contents,
398 * as they are internal strings used by Eet and trying to free them will surely
399 * break things.
400 * @until }
401 *
402 * Reading back plain data is simple. Just a call to eet_read() with the file
403 * to read from, and the name of the entry we are interested in. We get back
404 * our data and the passed @p size parameter will contain the size of it. If
405 * the data was stored compressed, it will decompressed first.
406 * @until }
407 *
408 * Another simple read for the set of strings from before, except those were
409 * deleted, so we should get a NULL return and continue normally.
410 * @until }
411 *
412 * Finally, we'll get our binary data in the same way we got the strings. Once
413 * again, it makes no difference for Eet what the data is, it's up to us to
414 * know how to handle it.
415 * @until {
416 *
417 * Now some cheating, we know that this data is an Eet file because, well...
418 * we just know it. So we are going to open it and take a look at its insides.
419 * For this, eet_open() won't work, as it needs to have a file on disk to read
420 * from and all we have is some data in RAM.
421 *
422 * So how do we do? One way would be to create a normal file and write down
423 * our data, then open it with eet_open(). Another, faster and more efficient
424 * if all we want to do is read the file, is to use eet_memopen_read().
425 * @until memopen
426 *
427 * As you can see, the size we got from our previous read was put to good use
428 * this time. Unlike the first one where all we had were strings, the size
429 * of the data read only serves to demonstrate that we are reading back the
430 * entire size of our original @p buf variable.
431 *
432 * A little peeking to see how many entries the file has and to make an
433 * example of eet_num_entries() to get that number when we don't care about
434 * their names.
435 * @until printf
436 *
437 * More cheating follows. Just like we knew this was an Eet file, we also know
438 * what key to read from, and ontop of that we know that the data in it is not
439 * compressed.
440 * Knowing all this allows us to take some shortcuts.
441 * @until read_direct
442 *
443 * That's a direct print of our data, whatever that data is. We don't want
444 * to worry about having to free it later, so we just used eet_direct_read()
445 * to tell Eet to gives a pointer to the internal data in the file, without
446 * duplicating it. Since we said that data was not compressed, we shouldn't
447 * worry about printing garbage to the screen (and yes, we also know the data
448 * is yet another string).
449 * We also don't care about the size of the data as it was stored in the file,
450 * so we passed NULL as the size parameter.
451 * One very important note about this, however, is that we don't care about
452 * the size parameter because the data in the file contains the null
453 * terminator for the string. So when using Eet to store strings this way,
454 * it's very important to consider whether you will keep that final null
455 * byte, or to always get the size read and do the necessary checks and copies.
456 * It's up to the user and the particular use cases to decide how this will
457 * be done.
458 *
459 * With everything done, close this second file and free the data used to open
460 * it. And this is important, we can't free that data until we are done with
461 * the file, as Eet is using it. When opening with eet_memopen_read(), the data
462 * passed to it must be available for as long as the the file is open.
463 * @until }
464 *
465 * Finally, we close the first file, shutdown all internal resources used by
466 * Eet and leave our main function, thus terminating our program.
467 * @until return
468 *
469 * You can look at the full code of the example @ref eet-file.c "here".

1867 * @defgroup Eet_Data_Group Eet Data Serialization
1868 *
1869 * Convenience functions to serialize and parse complex data
1870 * structures to binary blobs.
1871 *
1872 * While Eet core just handles binary blobs, it is often required
1873 * to save some structured data of different types, such as
1874 * strings, integers, lists, hashes and so on.
1875 *
1876 * Eet can serialize and then parse data types given some
1877 * construction instructions. These are defined in two levels:
1878 *
1879 * - #Eet_Data_Descriptor_Class to tell generic memory handling,
1880 * such as the size of the type, how to allocate memory, strings,
1881 * lists, hashes and so on.
1882 *
1883 * - #Eet_Data_Descriptor to tell inside such type, the members and
1884 * their offsets inside the memory blob, their types and
1885 * names. These members can be simple types or other
1886 * #Eet_Data_Descriptor, allowing hierarchical types to be
1887 * defined.
1888 *
1889 * Given that C provides no introspection, this process can be
1890 * quite cumbersome, so we provide lots of macros and convenience
1891 * functions to aid creating the types.
1892 *
1893 * We make now a quick overview of some of the most commonly used elements
1894 * of this part of the library. A simple example of a configuration system
1895 * will work as a somewhat real life example that is still simple enough to
1896 * follow.
1897 * Only the relevant sections will be shown here, but you can get the full
1898 * code @ref eet-data-simple.c "here".
1899 *
1900 * Ignoring the included headers, we'll begin by defining our configuration
1901 * struct.
1902 * @dontinclude eet-data-simple.c
1903 * @skip typedef
1904 * @until }
1905 *
1906 * When using Eet, you don't think in matters of what data the program needs
1907 * to run and which you would like to store. It's all the same and if it makes
1908 * more sense to keep them together, it's perfectly fine to do so. At the time
1909 * of telling Eet how your data is comprised you can leave out the things
1910 * that are runtime only and let Eet take care of the rest for you.
1911 *
1912 * The key used to store the config follows, as well as the variable used to
1913 * store our data descriptor.
1914 * This last one is very important. It's the one thing that Eet will use to
1915 * identify your data, both at the time of writing it to the file and when
1916 * loading from it.
1917 * @skipline MY_CONF
1918 * @skipline Eet_Data_Descriptor
1919 *
1920 * Now we'll see how to create this descriptor, so Eet knows how to handle
1921 * our data later on.
1922 * Begin our function by declaring an Eet_Data_Descriptor_Class, which is
1923 * used to create the actual descriptor. This class contains the name of
1924 * our data type, its size and several functions that dictate how Eet should
1925 * handle memory to allocate the necessary bits to bring our data to life.
1926 * You, as a user, will very hardly set this class' contents directly. The
1927 * most common scenario is to use one of the provided macros that set it using
1928 * the Eina data types, so that's what we'll be doing across all our examples.
1929 * @skip static void
1930 * @until eet_data_descriptor_stream_new
1931 *
1932 * Now that we have our descriptor, we need to make it describe something.
1933 * We do so by telling it which members of our struct we want it to know about
1934 * and their types.
1935 * The eet_data_descriptor_element_add() function takes care of this, but it's
1936 * too cumbersome for normal use, so several macros are provided that make
1937 * it easier to handle. Even with them, however, code can get very repetitive
1938 * and it's not uncommon to define custom macros using them to save on typing.
1939 * @skip #define
1940 * @until }
1941 *
1942 * Now our descriptor knows about the parts of our structure that we are
1943 * interesting in saving. You can see that not all of them are there, yet Eet
1944 * will find those that need saving and do the right thing. When loading our
1945 * data, any non-described fields in the structure will be zeroed, so there's
1946 * no need to worry about garbage memory in them.
1947 * Refer to the documentation of #EET_DATA_DESCRIPTOR_ADD_BASIC to understand
1948 * what our macro does.
1949 *
1950 * We are done with our descriptor init function and it's proper to have the
1951 * relevant shutdown. Proper coding guidelines indiciate that all memory
1952 * allocated should be freed when the program ends, and since you will most
1953 * likely keep your descriptor around for the life or your application, it's
1954 * only right to free it at the end.
1955 * @skip static void
1956 * @until }
1957 *
1958 * Not listed here, but included in the full example are functions to create
1959 * a blank configuration and free it. The first one will only be used when
1960 * no file exists to load from, or nothing is found in it, but the latter is
1961 * used regardless of where our data comes from. Unless you are reading direct
1962 * data from the Eet file, you will be in charge of freeing anything loaded
1963 * from it.
1964 *
1965 * Now it's time to look at how we can load our config from some file.
1966 * Begin by opening the Eet file normally.
1967 * @skip static My_Conf_Type
1968 * @until }
1969 *
1970 * And now we need to read the data from the file and decode it using our
1971 * descriptor. Fortunately, that's all done in one single step.
1972 * @until goto
1973 *
1974 * And that's it for all Eet cares about. But since we are dealing with a
1975 * common case, as is save and load of user configurations, the next fragment
1976 * of code shows why we have a version field in our struct, and how you can
1977 * use it to load older configuration files and update them as needed.
1978 * @until }
1979 *
1980 * Finally, clsoe the file and return the newly loaded config data.
1981 * @until }
1982 *
1983 * Saving data is just as easy. The full version of the following function
1984 * includes code to save to a temporary file first, so you can be sure not
1985 * to lose all your data in the case of a failure mid-writing. You can look
1986 * at it @ref eet-data-simple.c "here".
1987 * @skip static Eina_Bool
1988 * @until {
1989 * @skipline Eina_Bool ret
1990 * @skip eet_open
1991 * @until eet_close
1992 * @skip return
1993 * @until }
1994 *
1995 * To close, our main function, which doesn't do much. Just take some arguments
1996 * from the command line with the name of the file to load and another one
1997 * where to save again. If input file doesn't exist, a new config structure
1998 * will be created and saved to our output file.
1999 * @skip int main

2010/**
2011 * @page eet_data_nested_example Nested structures and Eet Data Descriptors
2012 *
2013 * We've seen already a simple example of how to use Eet Data Descriptors
2014 * to handle our structures, but it didn't show how this works when you
2015 * have structures inside other structures.
2016 *
2017 * Now, there's a very simple case of this, for when you have inline structs
2018 * to keep your big structure more organized, you don't need anything else
2019 * besides what @ref eet-data-simple.c "this simple example does".
2020 * Just use something like @p some_struct.sub_struct.member when adding the
2021 * member to the descriptor and it will work.
2022 *
2023 * For example:
2024 * @code
2025 * typedef struct
2026 * {
2027 * int a_number;
2028 * char *a_string;
2029 * struct {
2030 * int other_num;
2031 * int one_more;
2032 * } sub;
2033 * } some_struct;
2034 *
2035 * void some_function()
2036 * {
2037 * ...
2038 * my_desc = eet_data_descriptor_stream_new(&eddc);
2039 * EET_DATA_DESCRIPTOR_ADD_BASIC(my_desc, some_struct, "a_number",
2040 * a_number, EET_T_INT);
2041 * EET_DATA_DESCRIPTOR_ADD_BASIC(my_desc, some_struct, "a_string",
2042 * a_string, EET_T_STRING);
2043 * EET_DATA_DESCRIPTOR_ADD_BASIC(my_desc, some_struct, "sub.other_num",
2044 * sub.other_num, EET_T_INT);
2045 * EET_DATA_DESCRIPTOR_ADD_BASIC(my_desc, some_struct, "sub.one_more",
2046 * sub.one_more", EET_T_INT);
2047 * ...
2048 * }
2049 * @endcode
2050 *
2051 * But this is not what we are here for today. When we talk about nested
2052 * structures, what we really want are things like lists and hashes to be
2053 * taken into consideration automatically, and all their contents saved and
2054 * loaded just like ordinary integers and strings are.
2055 *
2056 * And of course, Eet can do that, and considering the work it saves you as a
2057 * programmer, we could say it's even easier to do than handling just integers.
2058 *
2059 * Let's begin with our example then, which is not all too different from the
2060 * simple one introduced earlier.
2061 *
2062 * We won't ignore the headers this time to show how easy it is to use Eina
2063 * data types with Eet, but we'll still skip most of the code that is not

2109/**
2110 * @page eet_data_file_descriptor Advanced use of Eet Data Descriptors
2111 *
2112 * A real life example is usually the best way to see how things are used,
2113 * but they also involve a lot more code than what needs to be shown, so
2114 * instead of going that way, we'll be borrowing some pieces from one in
2115 * the following example. It's been slightly modified from the original
2116 * source to show more of the varied ways in which Eet can handle our data.
2117 *
2118 * @ref eet-data-file_descriptor_01.c "This example" shows a cache of user
2119 * accounts and messages received, and it's a bit more interactive than
2120 * previous examples.
2121 *
2122 * Let's begin by looking at the structures we'll be using. First we have
2123 * one to define the messages the user receives and one for the one he posts.
2124 * Straight forward and nothing new here.
2125 * @dontinclude eet-data-file_descriptor_01.c
2126 * @skip typedef
2127 * @until My_Post
2128 *
2129 * One more to declare the account itself. This one will contain a list of
2130 * all messages received, and the posts we make ourselves will be kept in an
2131 * array. No special reason other than to show how to use arrays with Eet.
2132 * @until My_Account
2133 *
2134 * Finally, the main structure to hold our cache of accounts. We'll be looking
2135 * for these accounts by their names, so let's keep them in a hash, using
2136 * that name as the key.
2137 * @until My_Cache
2138 *
2139 * As explained before, we need one descriptor for each struct we want Eet
2140 * to handle, but this time we also want to keep around our Eet file and its
2141 * string dictionary. You will see why in a moment.
2142 * @skip Eet_Data_Descriptor
2143 * @until _my_post_descriptor
2144 * @skip Eet_File
2145 * @until Eet_Dictionary
2146 *
2147 * The differences begin now. They aren't much, but we'll be creating our
2148 * descriptors differently. Things can be added to our cache, but we won't
2149 * be modifying the current contents, so we can consider the data read from
2150 * it to be read-only, and thus allow Eet to save time and memory by not
2151 * duplicating thins unnecessary.
2152 * @skip static void
2153 * @until _my_post_descriptor
2154 *
2155 * As the comment in the code explains, we are asking Eet to give us strings
2156 * directly from the mapped file, which avoids having to load it in memory
2157 * and data duplication.
2158 * Of course, there are things to take into account when doing things this
2159 * way, and they will be mentioned as we encounter those special cases.
2160 *
2161 * Next comes the actual description of our data, just like we did in the
2162 * previous examples.
2163 * @skip #define
2164 * @until #undef
2165 * @until #define
2166 * @until #undef
2167 *
2168 * And the account struct's description doesn't add much new, but it's worth
2169 * commenting on it.
2170 * @skip #define
2171 * @until _my_post_descriptor
2172 *
2173 * How to add a list we've seen before, but now we are also adding an array.
2174 * There's nothing really special about it, but it's important to note that
2175 * the EET_DATA_DESCRIPTOR_ADD_VAR_ARRAY is used to add arrays of variable
2176 * length to a descriptor. That is, arrays just like the one we defined.
2177 * Since there's no way in C to know how long they are, we need to keep
2178 * track of the count ourselves and Eet needs to know how to do so as well.
2179 * That's what the @p posts_count member of our struct is for. When adding
2180 * our array member, this macro will look for another variable in the struct
2181 * named just like the array, but with @p _count attached to the end.
2182 * When saving our data, Eet will know how many elements the array contains
2183 * by looking into this count variable. When loading back from a file, this
2184 * variable will be set to the right number of elements.
2185 *
2186 * Another option for arrays is to use EET_DATA_DESCRIPTOR_ADD_ARRAY, which
2187 * takes care of fixed sized arrays.
2188 * For example, let's suppose that we want to keep track of only the last
2189 * ten posts the user sent, and we declare our account struct as follows
2190 * @code
2191 * typedef struct
2192 * {
2193 * unsigned int id;
2194 * const char *name;
2195 * Eina_List *messages;
2196 * My_Post posts[10];
2197 * } My_Account;
2198 * @endcode
2199 * Then we would add the array to our descriptor with
2200 * @code
2201 * EET_DATA_DESCRIPTOR_ADD_ARRAY(_my_account_descriptor, My_Account, "posts",
2202 * posts, _my_post_descriptor);
2203 * @endcode
2204 *
2205 * Notice how this time we don't have a @p posts_count variable in our struct.
2206 * We could have it for the program to keep track of how many posts the
2207 * array actually contains, but Eet no longer needs it. Being defined that
2208 * way the array is already taking up all the memory needed for the ten
2209 * elements, and it is possible in C to determine how much it is in code.
2210 * When saving our data, Eet will just dump the entire memory blob into the
2211 * file, regardless of how much of it is really used. So it's important to
2212 * take into consideration this kind of things when defining your data types.
2213 * Each has its uses, its advantages and disadvantages and it's up to you
2214 * to decide which to use.
2215 *
2216 * Now, going back to our example, we have to finish adding our data to the
2217 * descriptors. We are only missing the main one for the cache, which
2218 * contains our hash of accounts.
2219 * Unless you are using your own hash functions when setting the descriptor
2220 * class, always use hashes with string type keys.
2221 * @skip #define
2222 * @until }
2223 *
2224 * If you remember, we told Eet not to duplicate memory when possible at the
2225 * time of loading back our data. But this doesn't mean everything will be
2226 * loaded straight from disk and we don't have to worry about freeing it.
2227 * Data in the Eet file is compressed and encoded, so it still needs to be
2228 * decoded and memory will be allocated to convert it back into something we
2229 * can use. We also need to take care of anything we add in the current
2230 * instance of the program.
2231 * To summarize, any string we get from Eet is likely to be a pointer to the
2232 * internal dictionary, and trying to free it will, in the best case, crash
2233 * our application right away.
2234 *
2235 * So how do we know if we have to free a string? We check if it's part of
2236 * the dictionary, and if it's not there we can be sure it's safe to get
2237 * rid of it.
2238 * @skip static void
2239 * @skip }
2240 * @skip static void
2241 * @until }
2242 *
2243 * See how this is used when adding a new message to our cache.
2244 * @skip static My_Message
2245 * @until return msg
2246 * @until free(msg)
2247 * @until }
2248 *
2249 * Skipping all the utility functions used by our program (remember you can
2250 * look at the full example @ref eet-data-file_descriptor_01.c "here") we get to
2251 * our cache loading code. Nothing out of the ordinary at first, just the
2252 * same old open file, read data using our main descriptor to decode it
2253 * into something we can use and check version of loaded data and if it doesn't
2254 * match, do something accordingly.
2255 * @skip static My_Cache
2256 * @until }
2257 * @until }
2258 * @until }
2259 *
2260 * Then comes the interesting part. Remember how we kept two more global
2261 * variables with our descriptors? One of them we already used to check if
2262 * it was right to free a string or not, but we didn't know where it came from.
2263 * Loading our data straight from the mmapped file means that we can't close
2264 * it until we are done using it, so we need to keep its handler around until
2265 * then. It also means that any changes done to the file can, and will,
2266 * invalidate all our pointers to the file backed data, so if we add something
2267 * and save the file, we need to reload our cache.
2268 *
2269 * Thus our load function checks if we had an open file, if there is it gets
2270 * closed and our variable is updated to the new handler. Then we get the
2271 * string dictionary we use to check if a string is part of it or not.
2272 * Updating any references to the cache data is up you as a programmer to
2273 * handle properly, there's nothing Eet can do in this situation.
2274 * @until }
2275 *
2276 * The save function doesn't have anything new, and all that's left after it
2277 * is the main program, which doesn't really have anything of interest within
2278 * the scope of what we are learning.
