## About

Serialize C structs into csv files by providing only number of rows, field conversion functions and field sizes.

## Why

I have often found serialization / deserialization as one of most frequent tasks in software. While one can achieve the same by writing normal C code, it becomes a mundane and error prone task when you need to do it again for some other module / structure.

Also, by this project I want to highlight the separation of **user** definitions from the library definitions. The library (`core.c`) has no idea how the structures are implemented. It only knows how to retrieve them (`void*`) using function pointers passed in its config from the user layer. This **separation of control** is often desirable in large projects and also demonstrates good software practice of loosely coupled modules, while maintaining high cohesion inside a module.

While it may seem an over-work in this repo, but, if you follow the examples, you can add your own structure for serialization easily too. I have also provided *person* `struct` example which can use both global memory pool and heap storage for an array of people.

## Compile and run

```bash

make

./main.out

```

## Output

```c

struct Address_Internal_Rep {

    int flat_no;

    COUNTRY country;

    char city[20];

};

struct Person_Internal_Rep {

    char name[NAME_BUF_SIZE];

    char pronouns[PRONOUNS_BUF_SIZE];

    uint8_t age;

    Address_Internal_Rep address;

    Person_Internal_Rep* next;

};

```

gets converted into -> 

```csv

prabal, he/him, 25, flat_no. 204, Noida, IND, 

gopal, he/him, 23, flat_no. 101, Delhi, IND, 

shin dongjoon, he/him, 29, flat_no. 305, Gyeonggi-do, KOR, 

woo soyeon, she/her, 26, flat_no. 204, Busan, KOR,

```

Esentially, there are two major code files -  

- `core.c` (converts your struct into csv file)

- `external_definitions_person.c` (provide how to convert your struct into a string, call init api `csv_init()` and serialization api `v3()`)
