##About
|
|
Parson is a lighweight [json](http://json.org) 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.
|
|
|
|

|
|
|
|
##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.
|
|
```c
|
|
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 (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:
|
|
```
