Install Usage
------- -----
To clone the repository you should have Git installed. Just run: Download `jsmn.h`, include it, done.
$ git clone https://github.com/zserge/jsmn ```
#include "jsmn.h"
Repository layout is simple: jsmn.c and jsmn.h are library files, tests are in ...
the jsmn\_test.c, you will also find README, LICENSE and Makefile files inside. jsmn_parser p;
jsmntok_t t[128]; /* We expect no more than 128 JSON tokens */
To build the library, run `make`. It is also recommended to run `make test`. jsmn_init(&p);
Let me know, if some tests fail. r = jsmn_parse(&p, s, strlen(s), t, 128);
```
If build was successful, you should get a `libjsmn.a` library. Since jsmn is a single-header, header-only library, for more complex use cases
The header file you should include is called `"jsmn.h"`. you might need to define additional macros. `#define JSMN_STATIC` hides all
jsmn API symbols by making them static. Also, if you want to include `jsmn.h`
from multiple C files, to avoid duplication of symbols you may define `JSMN_HEADER` macro.
```
/* In every .c file that uses jsmn include only declarations: */
#define JSMN_HEADER
#include "jsmn.h"
/* Additionally, create one jsmn.c file for jsmn implementation: */
#include "jsmn.h"
```
