# RethinkDB driver for C++
This driver is compatible with RethinkDB 2.0. It is based on the
official RethinkDB Python driver.
* [RethinkDB server](http://rethinkdb.com/)
* [RethinkDB API docs](http://rethinkdb.com/api/python/)
## Example
```
#include <memory>
#include <cstdio>
#include <rethinkdb.h>
namespace R = RethinkDB;
int main() {
std::unique_ptr<R::Connection> conn = R::connect("localhost", 28015);
R::Cursor cursor = R::table("users").filter(R::row["age"] > 14).run(*conn);
for (R::Datum& user : cursor) {
printf("%s\n", user.as_json().c_str());
}
}
```
## Build
Requires a modern C++ compiler. to build and install, run:
```
make
make install
```
Will build `include/rethinkdb.h`, `librethinkdb++.a` and
`librethinkdb++.so` into the `build/` directory.
To include documentation from the Python driver in the header file,
pass the following argument to make.
```
make INCLUDE_PYTHON_DOCS=yes
```
To build in debug mode:
```
make DEBUG=yes
```
To install to a specific location:
```
make install prefix=/usr/local DESTDIR=
```
## Status
Still in early stages of development.
## Tests
This driver is tested against the upstream ReQL tests from the
RethinkDB repo, which are programmatically translated from Python to
C++. As of 34dc13c, all tests pass:
```
$ make test
...
SUCCESS: 2053 tests passed
```

////////////////////////////////////////////////////////////////////////////////
// THE HIGH-LEVEL VIEW //
////////////////////////////////////////////////////////////////////////////////
// Process: When you first open a connection, send the magic number
// for the version of the protobuf you're targeting (in the [Version]
// enum). This should **NOT** be sent as a protobuf; just send the
// little-endian 32-bit integer over the wire raw. This number should
// only be sent once per connection.
// The magic number shall be followed by an authorization key. The
// first 4 bytes are the length of the key to be sent as a little-endian
// 32-bit integer, followed by the key string. Even if there is no key,
// an empty string should be sent (length 0 and no data).
// Following the authorization key, the client shall send a magic number
// for the communication protocol they want to use (in the [Protocol]
// enum). This shall be a little-endian 32-bit integer.
// The server will then respond with a NULL-terminated string response.
// "SUCCESS" indicates that the connection has been accepted. Any other
// response indicates an error, and the response string should describe
// the error.
// Next, for each query you want to send, construct a [Query] protobuf
// and serialize it to a binary blob. Send the blob's size to the
// server encoded as a little-endian 32-bit integer, followed by the
// blob itself. You will recieve a [Response] protobuf back preceded
// by its own size, once again encoded as a little-endian 32-bit
// integer. You can see an example exchange below in **EXAMPLE**.
// A query consists of a [Term] to evaluate and a unique-per-connection
// [token].
// Tokens are used for two things:
// * Keeping track of which responses correspond to which queries.
// * Batched queries. Some queries return lots of results, so we send back
// batches of <1000, and you need to send a [CONTINUE] query with the same
// token to get more results from the original query.

// A [Term] is either a piece of data (see **Datum** above), or an operator and
// its operands. If you have a [Datum], it's stored in the member [datum]. If
// you have an operator, its positional arguments are stored in [args] and its
// optional arguments are stored in [optargs].
//
// A note about type signatures:
// We use the following notation to denote types:
// arg1_type, arg2_type, argrest_type... -> result_type
// So, for example, if we have a function `avg` that takes any number of
// arguments and averages them, we might write:
// NUMBER... -> NUMBER
// Or if we had a function that took one number modulo another:
// NUMBER, NUMBER -> NUMBER
// Or a function that takes a table and a primary key of any Datum type, then
// retrieves the entry with that primary key:
// Table, DATUM -> OBJECT
// Some arguments must be provided as literal values (and not the results of sub
// terms). These are marked with a `!`.
// Optional arguments are specified within curly braces as argname `:` value
// type (e.x `{noreply:BOOL}`)
// Many RQL operations are polymorphic. For these, alterantive type signatures
// are separated by `|`.
//
// The RQL type hierarchy is as follows:
// Top
// DATUM
// NULL
// BOOL
// NUMBER
// STRING
// OBJECT
// SingleSelection
// ARRAY
// Sequence
// ARRAY
// Stream
// StreamSelection
// Table
// Database
// Function
// Ordering - used only by ORDER_BY
// Pathspec -- an object, string, or array that specifies a path
// Error

This is a hack of tuntaposx. It's here for two reasons:
1) There seem to be issues with large MTUs in the original tuntap code,
so we set up our zt0 tap with the correct ZeroTier MTU as the default.
2) Lots of other mac products (VPNs, etc.) ship their own tap device
drivers that like to conflict with one another. This gives us no
choice but to play along. But we call our tap device zt0, which means
it won't conflict with everyone else's tap0.
3) It's nice to call the device zt0, same as Linux, for consistency across
*nix platforms. Mac does not seem to support interface renaming.
This will be placed in the ZeroTier home as a kext and is auto-loaded by the
ZeroTier One binary if /dev/zt0 is not found. It can also be auto-updated.
See this page for the original:
http://tuntaposx.sourceforge.net
