##About Parson is a lighweight json parser and reader written in C.
##Features
- Lightweight (only 2 files)
- Simple API
- Addressing json values with dot notation (similiar to C structs or objects in most OO languages, e.g. "objectA.objectB.value")
- C89 compatible
- Test suites
##Installation Run the following code:
git clone https://github.com/kgabis/parson.git
and copy parson.h and parson.c to you source code tree.
Run tests.sh to compile and run tests.
##Example Here is a function, which prints basic commit info (date, sha and author) from a github repository. It's also included in tests.c file, you can just uncomment and run it.
void print_commits_info(const char *username, const char *repo) {
JSON_Value *root_value;
JSON_Array *commits;
JSON_Object *commit;
int i;
char curl_command[512];
char cleanup_command[256];
char output_filename[] = "commits.json";
/* it ain't pretty, but it's not a libcurl tutorial */
sprintf(curl_command, "curl -s \"https://api.github.com/repos/%s/%s/commits\"\
> %s", username, repo, output_filename);
sprintf(cleanup_command, "rm -f %s", output_filename);
system(curl_command);
/* parsing json and validating output */
root_value = json_parse_file(output_filename);
if (root_value == NULL || json_value_get_type(root_value) != JSONArray) {
system(cleanup_command);
return;
}
/* getting array from root value and printing commit info */
commits = json_value_get_array(root_value);
printf("%-10.10s %-10.10s %s\n", "Date", "SHA", "Author");
for (i = 0; i < json_array_get_count(commits); i++) {
commit = json_array_get_object(commits, i);
printf("%.10s %.10s %s\n",
json_object_dotget_string(commit, "commit.author.date"),
json_object_get_string(commit, "sha"),
json_object_dotget_string(commit, "commit.author.name"));
}
/* cleanup code */
json_value_free(root_value);
system(cleanup_command);
}Calling print_commits_info("torvalds", "linux"); prints:
