Our program +only lists the latest commits, so the rest of the URL is +``list/USER/REPOSITORY/BRANCH``, where ``USER``, ``REPOSITORY`` and +``BRANCH`` are the GitHub user ID, the name of the repository, and the +name of the branch whose commits are to be listed, respectively. + +GitHub responds with a JSON object of the following form: + +.. code-block:: none + + { + "commits": [ + { + "id": "<the commit ID>", + "message": "<the commit message>", + <more fields, not important to this tutorial> + }, + { + "id": "<the commit ID>", + "message": "<the commit message>", + <more fields, not important to this tutorial> + }, + <more commits...> + ] + } + +In our program, the HTTP request is sent using the following +function:: + + static char *request(const char *url); + +It takes the URL as a parameter, preforms a HTTP GET request, and +returns a newly allocated string that contains the response body. If +the request fails, an error message is printed to stderr and the +return value is *NULL*. For full details, refer to :download:`the code +<github_commits.c>`, as the actual implementation is not important +here. + +.. _GitHub commits API: http://develop.github.com/p/commits.html + +.. _tutorial-the-program: + +The Program +=========== + +First the includes:: + + #include <string.h> + #include <jansson.h> + +Like all the programs using Jansson, we need to include +:file:`jansson.h`. + +The following definitions are used to build the GitHub commits API +request URL:: + + #define URL_FORMAT "http://github.com/api/v2/json/commits/list/%s/%s/master"; + #define URL_SIZE 256 + +The following function is used when formatting the result to find the +first newline in the commit message:: + + /* Return the offset of the first newline in text or the length of + text if there's no newline */ + static int newline_offset(const char *text) + { + const char *newline = strchr(text, '\n'); + if(!newline) + return strlen(text); + else + return (int)(newline - text); + } + +The main function follows. In the beginning, we first declare a bunch +of variables and check the command line parameters:: + + size_t i; + char *text; + char url[URL_SIZE]; + + json_t *root; + json_error_t error; + json_t *commits; + + if(argc != 3) + { + fprintf(stderr, "usage: %s USER REPOSITORY\n\n", argv[0]); + fprintf(stderr, "List commits at USER's REPOSITORY.\n\n"); + return 2; + } + +Then we build the request URL using the user and repository names +given as command line parameters:: + + snprintf(url, URL_SIZE, URL_FORMAT, argv[1], argv[2]); + +This uses the ``URL_SIZE`` and ``URL_FORMAT`` constants defined above. +Now we're ready to actually request the JSON data over the web:: + + text = request(url); + if(!text) + return 1; + +If an error occurs, our function ``request`` prints the error and +returns *NULL*, so it's enough to just return 1 from the main +function. + +Next we'll call :func:`json_loads()` to decode the JSON text we got +as a response:: + + root = json_loads(text, 0, &error); + free(text); + + if(!root) + { + fprintf(stderr, "error: on line %d: %s\n", error.line, error.text); + return 1; + } + +We don't need the JSON text anymore, so we can free the ``text`` +variable right after decoding it. If :func:`json_loads()` fails, it +returns *NULL* and sets error information to the :type:`json_error_t` +structure given as the second parameter. In this case, our program +prints the error information out and returns 1 from the main function. + +Now we're ready to extract the data out of the decoded JSON response. +The structure of the response JSON was explained in section +:ref:`tutorial-github-commits-api`. + +First, we'll extract the ``commits`` array from the JSON response:: + + commits = json_object_get(root, "commits"); + if(!json_is_array(commits)) + { + fprintf(stderr, "error: commits is not an array\n"); + return 1; + } + +This is the array that contains objects describing latest commits in +the repository. We check that the returned value really is an array. +If the key ``commits`` doesn't exist, :func:`json_object_get()` +returns *NULL*, but :func:`json_is_array()` handles this case, too. + +Then we proceed to loop over all the commits in the array:: + + for(i = 0; i < json_array_size(commits); i++) + { + json_t *commit, *id, *message; + const char *message_text; + + commit = json_array_get(commits, i); + if(!json_is_object(commit)) + { + fprintf(stderr, "error: commit %d is not an object\n", i + 1); + return 1; + } + ... + +The function :func:`json_array_size()` returns the size of a JSON +array. First, we again declare some variables and then extract the +i'th element of the ``commits`` array using :func:`json_array_get()`. +We also check that the resulting value is a JSON object. + +Next we'll extract the commit ID and commit message, and check that +they both are JSON strings:: + + id = json_object_get(commit, "id"); + if(!json_is_string(id)) + { + fprintf(stderr, "error: commit %d: id is not a string\n", i + 1); + return 1; + } + + message = json_object_get(commit, "message"); + if(!json_is_string(message)) + { + fprintf(stderr, "error: commit %d: message is not a string\n", i + 1); + return 1; + } + ... + +And finally, we'll print the first 8 characters of the commit ID and +the first line of the commit message. A C-style string is extracted +from a JSON string using :func:`json_string_value()`:: + + message_text = json_string_value(message); + printf("%.8s %.*s\n", + json_string_value(id), + newline_offset(message_text), + message_text); + } + +After sending the HTTP request, we decoded the JSON text using +:func:`json_loads()`, remember? It returns a *new reference* to the +JSON value it decodes. When we're finished with the value, we'll need +to decrease the reference count using :func:`json_decref()`.

Most programs +can be modified to work with 2.0 by adding a ``0`` as the second +parameter to all calls of :func:`json_loads()`, :func:`json_loadf()` +and :func:`json_load_file()`. + + +Compatibility +============= + +Jansson 2.0 is backwards incompatible with the Jansson 1.x releases. +It is ABI incompatible, i.e. all programs dynamically linking to the +Jansson library need to be recompiled. It's also API incompatible, +i.e. the source code of programs using Jansson 1.x may need +modifications to make them compile against Jansson 2.0. + +All the 2.x releases are guaranteed to be backwards compatible for +both ABI and API, so no recompilation or source changes are needed +when upgrading from 2.x to 2.y. + + +List of Incompatible Changes +============================ + +**Decoding flags** + For future needs, a ``flags`` parameter was added as the second + parameter to all decoding functions, i.e. :func:`json_loads()`, + :func:`json_loadf()` and :func:`json_load_file()`. All calls to + these functions need to be changed by adding a ``0`` as the second + argument. For example:: + + /* old code */ + json_loads(input, &error); + + /* new code */ + json_loads(input, 0, &error); + + +**Underlying type of JSON integers** + The underlying C type of JSON integers has been changed from + :type:`int` to the widest available signed integer type, i.e. + :type:`long long` or :type:`long`, depending on whether + :type:`long long` is supported on your system or not. This makes + the whole 64-bit integer range available on most modern systems. + + ``jansson.h`` has a typedef :type:`json_int_t` to the underlying + integer type. :type:`int` should still be used in most cases when + dealing with smallish JSON integers, as the compiler handles + implicit type coercion. Only when the full 64-bit range is needed, + :type:`json_int_t` should be explicitly used. + + +**Maximum encoder indentation depth** + The maximum argument of the ``JSON_INDENT()`` macro has been + changed from 255 to 31, to free up bits from the ``flags`` + parameter of :func:`json_dumps()`, :func:`json_dumpf()` and + :func:`json_dump_file()`. If your code uses a bigger indentation + than 31, it needs to be changed. + + +**Unsigned integers in API functions** + Version 2.0 unifies unsigned integer usage in the API. All uses of + :type:`unsigned int` and :type:`unsigned long` have been replaced + with :type:`size_t`. This includes flags, container sizes, etc. + This should not require source code changes, as both + :type:`unsigned int` and :type:`unsigned long` are usually + compatible with :type:`size_t`.
