# json-scanner ~ just as cheap as me...
Hand-made scanner for JavaScript Object Notation (**JSON**). Just for FUN & LEARNING ~!
> [!NOTE]
> There are lot of things to do. For example, it does NOT care about special character or escape squences inside the string and will identify them as an error.
## ⟫ Example ?
Running this scanner on following test **JSON** file... :
```json
{
"firstName": "John",
"lastName": "Doe",
"email": "john.doe@web.com",

"favoriteColors: ["Red", "Green", "Blue"],

## ⟫ Compile & Run
- Make sure `make` is installed. Following command can be used for Debian based distros to install it:
```bash
sudo apt update && sudo apt install make
```
- Compile it with the following command:
```bash
make sjson
```
- A new directory `build` will be created. `cd` into it and run `sjson` on any valid `.json` file:
```bash
cd build/
./sjson test.json
```
