Experimental compile-time string manipulation C++17 library
# Install
```
git clone --recursive https://github.com/ChristianPanov/static_string
```
# Features
- Written in modern C++17
- Compile-time
- std::string-like interface
# Usage
## Basic Usage
```cpp
#include "static_string.h"

#include

int main()
{
constexpr cts::static_string str = "Compile-time ";
constexpr cts::static_string str2 = "string";

static_assert(str2.size() == 6);
static_assert(str.empty() == false);
static_assert(str[1] == 'o');
static_assert(str.contains("Compile") == true);
static_assert(str.contains("Runtime") == false);

static_assert(str + str2 == "Compile-time string");
static_assert(str != str2);

std::cout << str + str2 << '\n';

return 0;
}
```
**NOTE:** When initializing the string object on instantiation, the template arguments can be deduced, thus, can be omitted.
#### Example
```cpp
#include "static_string.h"

int main()
{
constexpr cts::static_string str = "Compile-time string";

return 0;
}
```
## Find Substring
```cpp
#include "static_string.h"

int main()
{
constexpr cts::static_string str = "Compile-time string time";

//By default, the position offset is 0
static_assert(str.find("time") == 8);

//Find substring after a given position
static_assert(str.find<9>("time") == 20);

static_assert(str.rfind("time") == 20);

//Find substring after a given position
static_assert(str.rfind<20>("time") == 8);

return 0;
}
```
## Return Substring and Reversed Substring
```cpp
#include "static_string.h"

int main()
{
constexpr cts::static_string str = "Compile-time string time";

static_assert(str.substr<0, 6>() == "Compile");
static_assert(str.substr() == "time");

static_assert(str.rsubstr() == "emit");

return 0;
}
```
## Replace Substring
```cpp
#include "static_string.h"

int main()
{
constexpr cts::static_string str = "Compile-time string time";
constexpr auto replaced = str.replace("REPLACED");

static_assert(replaced == "Compile-REPLACED string time");

return 0;
}
```
## Starts With & Ends With
```cpp
#include "static_string.h"

int main()
{
constexpr cts::static_string url = "https://cppreference.com";

static_assert(url.starts_with("https"));
static_assert(!url.starts_with("ftp"));
static_assert(url.ends_with(".com"));
static_assert(!url.ends_with(".org"));

return 0;
}
```
