## Installation | ||
### Windows | ||
Download the zip file from [the latest release](https://github.com/AaravMalani/libjson/releases/latest) and [add it to | ||
the Visual Studio link arguments](https://learn.microsoft.com/en-us/cpp/build/adding-references-in-visual-cpp-projects?view=msvc-170) | ||
OR | ||
Build from source | ||
```bat | ||
git clone https://github.com/AaravMalani/libjson/ | ||
cd libjson | ||
cmake -S . -B build | ||
cd build | ||
cmake --build . | ||
cd .. | ||
rem The .dll and .lib file is in the build directory | ||
rem The include files are in the include directory | ||
``` | ||
### Debian-based Linux | ||
Download the [`.deb`](https://github.com/AaravMalani/libjson/releases/latest) file and run | ||
```bash | ||
sudo dpkg -i <file> | ||
``` | ||
OR | ||
Build from source | ||
|
||
### Red Hat / CentOS / Fedora | ||
Download the [`.rpm`](https://github.com/AaravMalani/libjson/releases/latest) file and | ||
|
||
### Linux (From Source) | ||
```bash | ||
git clone https://github.com/AaravMalani/libjson/ | ||
cd libjson | ||
cmake -S . -B build | ||
cd build | ||
sudo make install | ||
cd .. | ||
``` | ||
|
||
## Usage | ||
```c | ||
#include <json.h> | ||
|
||
int main(int argc, char** argv){ | ||
JSONElement* element = parseJSON("{\"a\":\"b\"}", NULL); // The second argument is for inner recursed calls and can therefore be NULL | ||
printf("%s\n", (char*) getElement(element, "a")->data); | ||
freeJSONElement(element); | ||
element = parseJSON("{\"a\":[1.0, -1.4]}", NULL); | ||
printf("%s\n", (char*) getElement(element, 2, "a", 0)->data); | ||
freeJSONElement(element); | ||
|
||
return 0; | ||
} | ||
``` | ||
For all the different types, look at `include/json.h` | ||
