Welcome to cJSON.
cJSON aims to be the dumbest possible parser that you can get your job done with.
It's a single file of C, and a single header file.
JSON is described best here: http://www.json.org/
It's like XML, but fat-free. You use it to move data around, store things, or just
generally represent your program's state.
First up, how do I build?
Add cJSON.c to your project, and put cJSON.h somewhere in the header search path.
For example, to build the test app:
gcc cJSON.c test.c -o test -lm
./test
As a library, cJSON exists to take away as much legwork as it can, but not get in your way.
As a point of pragmatism (i.e. ignoring the truth), I'm going to say that you can use it
in one of two modes: Auto and Manual. Let's have a quick run-through.
I lifted some JSON from this page: http://www.json.org/fatfree.html
That page inspired me to write cJSON, which is a parser that tries to share the same
philosophy as JSON itself. Simple, dumb, out of the way.
Some JSON:
{
"name": "Jack (\"Bee\") Nimble",
"format": {
"type": "rect",
"width": 1920,
"height": 1080,
"interlace": false,
"frame rate": 24
}
}
Assume that you got this from a file, a webserver, or magic JSON elves, whatever,
you have a char * to it. Everything is a cJSON struct.
Get it parsed:
cJSON *root = cJSON_Parse(my_json_string);
This is an object. We're in C. We don't have objects. But we do have structs.
What's the framerate?
cJSON *format = cJSON_GetObjectItem(root,"format");
int framerate = cJSON_GetObjectItem(format,"frame rate")->valueint;
Want to change the framerate?
cJSON_GetObjectItem(format,"frame rate")->valueint=25;
Back to disk?
char *rendered=cJSON_Print(root);
Finished? Delete the root (this takes care of everything else).
cJSON_Delete(root);
That's AUTO mode. If you're going to use Auto mode, you really ought to check pointers
before you dereference them. If you want to see how you'd build this struct in code?
cJSON *root,*fmt;
root=cJSON_CreateObject();
cJSON_AddItemToObject(root, "name", cJSON_CreateString("Jack (\"Bee\") Nimble"));
cJSON_AddItemToObject(root, "format", fmt=cJSON_CreateObject());
cJSON_AddStringToObject(fmt,"type", "rect");
cJSON_AddNumberToObject(fmt,"width", 1920);
cJSON_AddNumberToObject(fmt,"height", 1080);
cJSON_AddFalseToObject (fmt,"interlace");
cJSON_AddNumberToObject(fmt,"frame rate", 24);
Hopefully we can agree that's not a lot of code? There's no overhead, no unnecessary setup.
Look at test.c for a bunch of nice examples, mostly all ripped off the json.org site, and
a few from elsewhere.
What about manual mode? First up you need some detail.
Let's cover how the cJSON objects represent the JSON data.
cJSON doesn't distinguish arrays from objects in handling; just type.
Each cJSON has, potentially, a child, siblings, value, a name.
The root object has: Object Type and a Child
The Child has name "name", with value "Jack ("Bee") Nimble", and a sibling:
Sibling has type Object, name "format", and a child.
That child has type String, name "type", value "rect", and a sibling:
Sibling has type Number, name "width", value 1920, and a sibling:
Sibling has type Number, name "height", value 1080, and a sibling:
Sibling hs type False, name "interlace", and a sibling:
Sibling has type Number, name "frame rate", value 24
Here's the structure:
typedef struct cJSON {
struct cJSON *next,*prev;
struct cJSON *child;
int type;
char *valuestring;
int valueint;
double valuedouble;
char *string;
} cJSON;
By default all values are 0 unless set by virtue of being meaningful.
next/prev is a doubly linked list of siblings. next takes you to your sibling,
prev takes you back from your sibling to you.
Only objects and arrays have a "child", and it's the head of the doubly linked list.
A "child" entry will have prev==0, but next potentially points on. The last sibling has next=0.
The type expresses Null/True/False/Number/String/Array/Object, all of which are #defined in
cJSON.h
A Number has valueint and valuedouble. If you're expecting an int, read valueint, if not read
valuedouble.
Any entry which is in the linked list which is the child of an object will have a "string"
which is the "name" of the entry. When I said "name" in the above example, that's "string".
"string" is the JSON name for the 'variable name' if you will.
Now you can trivially walk the lists, recursively, and parse as you please.
You can invoke cJSON_Parse to get cJSON to parse for you, and then you can take
the root object, and traverse the structure (which is, formally, an N-tree),
and tokenise as you please. If you wanted to build a callback style parser, this is how
you'd do it (just an example, since these things are very specific):
void parse_and_callback(cJSON *item,const char *prefix)
{
while (item)
{
char *newprefix=malloc(strlen(prefix)+strlen(item->name)+2);
sprintf(newprefix,"%s/%s",prefix,item->name);
int dorecurse=callback(newprefix, item->type, item);
if (item->child && dorecurse) parse_and_callback(item->child,newprefix);
item=item->next;
free(newprefix);
}
}
The prefix process will build you a separated list, to simplify your callback handling.
The 'dorecurse' flag would let the callback decide to handle sub-arrays on it's own, or
let you invoke it per-item. For the item above, your callback might look like this:
int callback(const char *name,int type,cJSON *item)
{
if (!strcmp(name,"name")) { /* populate name */ }
else if (!strcmp(name,"format/type") { /* handle "rect" */ }
else if (!strcmp(name,"format/width") { /* 800 */ }
else if (!strcmp(name,"format/height") { /* 600 */ }
else if (!strcmp(name,"format/interlace") { /* false */ }
else if (!strcmp(name,"format/frame rate") { /* 24 */ }
return 1;
}
Alternatively, you might like to parse iteratively.
You'd use:
void parse_object(cJSON *item)
{
int i; for (i=0;i<cJSON_GetArraySize(item);i++)
{
cJSON *subitem=cJSON_GetArrayItem(item,i);
// handle subitem.
}
}
Or, for PROPER manual mode:
void parse_object(cJSON *item)
{
cJSON *subitem=item->child;
while (subitem)
{
// handle subitem
if (subitem->child) parse_object(subitem->child);
subitem=subitem->next;
}
}
Of course, this should look familiar, since this is just a stripped-down version
of the callback-parser.
This should cover most uses you'll find for parsing. The rest should be possible
to infer.. and if in doubt, read the source! There's not a lot of it! ;)
In terms of constructing JSON data, the example code above is the right way to do it.
You can, of course, hand your sub-objects to other functions to populate.
Also, if you find a use for it, you can manually build the objects.
For instance, suppose you wanted to build an array of objects?
cJSON *objects[24];
cJSON *Create_array_of_anything(cJSON **items,int num)
{
int i;cJSON *prev, *root=cJSON_CreateArray();
for (i=0;i<24;i++)
{
if (!i) root->child=objects[i];
else prev->next=objects[i], objects[i]->prev=prev;
prev=objects[i];
}
return root;
}
and simply: Create_array_of_anything(objects,24);
cJSON doesn't make any assumptions about what order you create things in.
You can attach the objects, as above, and later add children to each
of those objects.
As soon as you call cJSON_Print, it renders the structure to text.
The test.c code shows how to handle a bunch of typical cases. If you uncomment
the code, it'll load, parse and print a bunch of test files, also from json.org,
which are more complex than I'd care to try and stash into a const char array[].
Enjoy cJSON!
