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 :) 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 0.31.01 - 0.31.03 * Linux wine together with the Windows versions 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). Contributing to DFHack ---------------------- Several things should be kept in mind when contributing to DFHack. Keep the same coding style. DFhack uses ANSI formatting and four spaces as indentation. Line endings are UNIX. Code not following this won't make me happy, because I'll have to fix it. * How to get new code into DFHack You can send patches or make a clone of the github repo and ask me on the IRC channel to pull your code in. I'll review it and see if there are any problems. I'll fix them if they are minor. Fixes are higher in priority. If you want to work on something, but don't know what, check out http://github.com/peterix/dfhack/issues -- this is also the place for new ideas. * Layout for tools dfhack/ The folder for core dfhack. The libraries are in there. tools/ This is used for stable and supported tools. These get distributed in binary releases and should be tested. examples/ This folder has some examples that show how to use certain parts of dfhack. playground/ And finally, here should be placed any quick hacks and testing tools. Don't put untested or experimental things in tools/. * Layout for core dfhack dfhack/ -- the main library lives here dfhack/include -- header files for the main library belong here dfhack/modules -- source of the client modules goes here dfhack/include/modules -- headers for client modules dfhack/shm -- the server part along with its modules dfhack/python -- folder for the pytthon bindings dfhack/depends -- dependencies. an XML parser, an MD5 implementation and terminal arguments parser. * Modules - what are they? DFHack uses modules to partition sets of features into manageable chunks. A module can have both client and server side. Client side is the part that goes into the main library and is generally written in C++. It is exposed to the users of DFHack. Server side is used inside DF and serves to accelerate the client modules. This is written mostly in C style. There's a Core module that shouldn't be changed, because it defines the basic commands like reading and writing raw data. The client parts for the Core module are the various implementations of the Process interface. A good example of a module is Maps. Named the same in both client and server, it allows accelerating the reading of map blocks. Communication between modules happens by using shared memory. This is pretty fast, but needs quite a bit of care to not break. * Dependencies If you want to add dependencies, think twice about it. All dependencies for core dfhack should be either public domain or require attribution at most. Dependencies for tools can be either that, or any Free Software licenses. * Current internal dependencies tinyxml: used by core dfhack to read offset definitions from Memory.xml md5: an implementation of the MD5 hash algorithm. Used for identifying DF binaries on Linux. argstream: Allows reading terminal application arguments. GPL! * Current external dependencies wide-character ncurses: used for the veinlook tool on Linux. python 2.6: required for building and using the python bindings. * Build-time dependencies cmake: you need cmake to generate the build system and some configuration headers 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. - dfcleanmap : Cleans all the splatter that get scattered all over the map. Only exception is mud. It leaves mud alone. - dfexpbench : Just a simple benchmark of the data export speed. - dfliquids : A command prompt for liquid creation and manipulation (the Moses effect included!) Also allows painting obsidian walls directly. Note: Spawning and deleting liquids can F up pathing data and temperatures (creating heat traps). You've been warned. - dfposition : Prints the current DF window properties and cursor position. - dfprospector: Lists all available minerals on the map and how much of them there is. - dfreveal : Reveals the whole map, waits for input and hides it again. If you close the tool while it waits, the map remains revealed. - dfsuspend : Test of the process suspend/resume mechanism. - dfunstuck : Use if you prematurely close any of the tools and DF appears to be stuck. - dfvdig : Designates a whole vein for digging. Point the cursor at a vein and run this thing :) - Your tool here: Write one ;) Memory offset definitions ------------------------- The file with memory offset definitions used by dfhack can be found in the output folder. ~ EOF ~
