# Project

This is the text buffer implementation described in [Text Editor Data Structures](https://cdacamar.github.io/data%20structures/algorithms/benchmarking/text%20editors/c++/editor-data-structures/?fbclid=IwAR1KPqHQU-torrzSq7LKWgK3uUZsTaoEpiAQeDT8XlvlOD3MCSt3sEl2YXc).

## API

Building:

```c++

using namespace PieceTree;

TreeBuilder builder;

builder.accept("ABC");

builder.accept("DEF");

auto tree = builder.create();

// Resulting total buffer: "ABCDEF"

```

Insertion:

```c++

tree.insert(CharOffset{ 0 }, "foo");

// Resulting total buffer: "fooABCDEF"

```

Deletion:

```c++

tree.remove(CharOffset{ 6 }, Length{ 3 });

// Resulting total buffer: "fooABC"

```

Line retrieval:

```c++

std::string buf;

tree.get_line_content(&buf, Line{ 1 });

// 'buf' contains "fooABC"

```

Iteration:

```c++

for (char c : buf)

{

    printf("%c", c);

}

```

## Building

If you're on Windows, open a developer command prompt and invoke `b.bat`.  Do the same for essentially any other compiler except change the flags to be specific to your compiler.  It's all standard C++ all the way down.
