Minetest Mapper C++
===================

.. image:: https://travis-ci.org/minetest/minetestmapper.svg?branch=master
    :target: https://travis-ci.org/minetest/minetestmapper

A port of minetestmapper.py to C++ from https://github.com/minetest/minetest/tree/master/util.
This version is both faster and provides more features than the now deprecated Python script.

Requirements
------------

* libgd
* sqlite3
* leveldb (optional, set ENABLE_LEVELDB=1 in CMake to enable leveldb support)
* hiredis (optional, set ENABLE_REDIS=1 in CMake to enable redis support)

e.g. on Debian:
^^^^^^^^^^^^^^^

	sudo apt-get install libgd-dev libsqlite3-dev libleveldb-dev libhiredis-dev

Compilation
-----------

::

    cmake . -DENABLE_LEVELDB=1
    make -j2

Usage
-----

`minetestmapper` has two mandatory paremeters, `-i` (input world path)
and `-o` (output image path).

::

    ./minetestmapper -i ~/.minetest/worlds/my_world/ -o map.png
