Introduction
------------

DFHack is a Dwarf Fortress memory access library and a set of basic tools using 
this library. The library is a work in progress, so things might change as more
tools are written for it.

It is an attempt to unite the various ways tools access DF memory and allow for
easier development of new tools.

Getting DFHack
----------------
The project is currently hosted on github, for both source and binaries:
  http://github.com/peterix/dfhack

* Packages

The library and tools are packaged for Archlinux and are available both in AUR
and the arch-games repository.

The package name is dfhack-git :)

Clarification
-------------

'fake SDL.dll', 'SHM', 'libdfconnect' and 'shim library' are basically the same
thing. A library that sits between DFHack and DF, provides some extra features,
synchronisation and access control. You should use it for everything that writes
data back to DF.

You'll need the SHM to attach more than one tool to DF on Linux.
The DFHack version of Dwarf Therapist requires it for writing creature names
and professions.

See 'Using DFHack Tools' for instructions on installing it.

Compatibility
-------------

DFHack works on Windows XP, Vista, 7 or any modern Linux distribution.

Windows 2000 is currently *not supported* due to missing OS functionality.
If you know how to easily suspend processes, you can fix it :)

OSX is also not supported due to lack of developers with a Mac.

Currently supported Dwarf Fortress versions:
* Windows
  38a - 40d19_2

* Linux
  40d2 - 40d19

Currently supported DF versions *by the SHM*:
* Windows
  40d15 - 40d19
  
* Linux
  40d9 - 40d19 (40d2 - 40d8 might work, but are untested)

Using the library as a developer
--------------------------------

The library is compilable under Linux with GCC and under Windows with MinGW32
and MSVC compilers. It is using the cmake build system. See COMPILE for details.

DFHack is using the zlib/libpng license. This makes it easy to link to it, use
it in-source or add your own extensions. Contributing back to the dfhack
repository is welcome and the right thing to do :)

At the time of writing there's no API reference or documentation. The code does
have a lot of comments though (and getting better all the time).


Using DFHack Tools
------------------

The project comes with a special extra library you should add to your DF
installation. It's used to boost the transfer speed between DF and DFHack, and
provide data consistency and synchronization. DFHack will work without the
library, but at suboptimal speeds and the consistency of data written back
to DF is questionable.

!!!     on Windows this currently only works with DF 40d15 - 40d19_2      !!!
                  On Linux, it works with DF 40d9 - 40d19

!!! use the pre-compiled library intended for your OS and version of DF !!!
               You can find them in the 'precompiled' folder.
               

 ** Installing on Windows
 - Open your DF folder, locate SDL.dll and rename it to SDLreal.dll (making
   a backup of it is a good idea)
 - Copy the right DFHack SDL.dll into your DF folder.
 - Restart DF if it is running

 ** Unistalling on Windows
 - Open your DF folder, locate SDL.dll and delete it
 - Rename SDLreal.dll to SDL.dll
 - Restart DF if it is running


 ** Installing on Linux
 - Open your DF folder and the libs folder within it
 - copy DFHack libdfconnect.so to the libs folder
 - copy the df-hacked script to your DF folder
 - Use this new startup script to start DF
 
 ** Replacing libdfconnect.so
 - Make sure you close DF before you replace this file! DF crashes whn you don't
   close it first!

 ** Uninstalling on Linux
 - Open your DF and DF/libs folders
 - Delete libdfconnect.so and the dfhacked startup script
 - Go back to using the df startup script


Tools
-----

All the DFHack tools are terminal programs. This might seem strange to Windows
users, but these are meant mostly as examples for developers. Still, they can
be useful and are cross-platform just like the library itself.

If the tool writes back to DF's memory, make sure you are using the shared
memory interface mentioned in the previous section!

* catsplosion- Makes all cats pregnant and due in 100 game steps. Use with care.

* magma_create - creates 7/7 magma at the DF's cursor

* reveal     - plain old reveal tool. It reveals all the map blocks already
               initialized by DF.

* veinlook   - a silly map viewer. It can mass-dig veins in a map square.
               (Linux only)

* prospector - scans the map for minerals. by default it only scans only visible
               veins. You can make it show hidden things with '-a' and base rock
               and soil layers with '-b'. These can be combined ('-ab')

* cleanmap   - cleans mud, vomit, snow and all kinds of mess from the map.
               It will clean your irrigated farms too, so consider yourself
               warned.

* incrementalsearch - incremental search utility (Linux only).

* bauxite - converts all mechanisms into bauxite mechanisms.

* itemdesignator - Allows mass-designating items by type and material - dump,
                   forbid, melt and set on fire ;)
* digger         - allows designating tiles for digging/cutting/ramp removal

  A list of accepted tile classes:
        1  = WALL
        2  = PILLAR
        3  = FORTIFICATION
        
        4  = STAIR_UP
        5  = STAIR_DOWN
        6  = STAIR_UPDOWN
        
        7  = RAMP
        8  = RAMP_TOP
        
        9  = FLOOR
        10  = TREE_DEAD
        11 = TREE_OK
        12 = SAPLING_DEAD
        13 = SAPLING_OK
        14 = SHRUB_DEAD
        15 = SHRUB_OK
        16 = BOULDER
        17 = PEBBLES
  
  Example : dfdigger -o 100,100,15 -t 9,10 -m 10
  This will start looking for trees at coords 100,100,15 and designate ten of them for cutting.

 
Memory offset definitions

The file with memory offset definitions used by dfhack can be found in the
output folder.
