## Data Generator
a simple domain specific language which allows you to generate data fast and easy
## Usage
Here is an example of how to generate data of a+b problem using data generator
create a new text file named `example.txt`
open the editor and write
```
{i32} {i32}
```
execute using data generator
```bash
## linux
./data_generator -f example.txt -c 10
## replace `./data_generator` to `data_generator.exe` in windows
```
waiting for some time and it is done,how easy it is!
## Tokens
### single tokens
here a some single tokens which are allow to use in data_generator
```rust
i16 //short
i32 //int
i64 //long long
i128 //int128_t
/*tokens start with u are all the tokens above but unsigned.So no marks here*/
u16
u32
u64
u128
char // A UTF-8 charaters
string //ASCII. range from 20 to 126 (that means no control charaters.Will add some later) (the maxium len are u16::MAX)
bigint //maxium len are u16::MAX
```
### multiple tokens
TODO...
## TODOs
add multiple tokens (allows user to control the random data more fine)
add documentations for the source code
