Linux support!

Both DF and DFHack now run natively on Linux. If you're on Linux, we encourage you to try it! The interface is noticeably snappier, FPS is up, and load times are reduced. If you're subscribed to DF and DFHack on Steam, here's how to switch over:

• In the Steam client, open the properties for Dwarf Fortress
• In the "Betas" section, switch to the "beta" branch
• Let that finish updating
• Select the "Compatibility" section and deselect "Force the use of a specific Steam Play compatibility tool"
• DF should update again with the Linux native version

You can tell if you did it right if you no longer have Dwarf Fortress.exe in your DF directory and instead have dwarfort, which is the Linux binary. The plan is to "officially" release Linux support with DF 50.10, so once DF 50.10 comes out, you should be able to switch back to the default Steam branch and keep the native Linux support.

Then, do the same thing for DFHack. switching to the "beta" branch (if you're not there already) and turning off the compatibility layer.

Sometimes, Steam says you've got the Linux version, but when you look you see you still have Dwarf Fortress.exe instead of dwarfort. Try re-enabling the Proton compatibility layer and then turning off the compatibility layer again.

Major caveat for this beta release

This particular beta release of Dwarf Fortress has address layout randomization enabled. This causes some trouble for DFHack since DFHack needs to know the memory addresses of several key data structures. For this release only, be sure to start DF by launching DFHack from the Steam client or by running the ./dfhack commandline startup script. That will normalize the address space and allow DF to run with DFHack. Otherwise, DF will crash on startup. Again, this is only for this release. Future releases will not need this workaround and should go back to allowing you to start DF from either the Dwarf Fortress or DFHack Steam client entries, or from either the ./dwarfort or ./dfhack commandline commands.

The DFHack terminal console works differently on Linux

You can run DF with DFHack by starting DFHack in the Steam client. However, if you want an external DFHack terminal console, you have to run from the commandline.

On Windows, you could use the show command to pop up an external DFHack terminal console. You could use this for running DFHack commands from outside the game window, and the external terminal is the only way to run commandline-interactive DFHack commands like tiletypes and the interactive mode of the lua interpreter.

Linux has a different method of providing a terminal console. You can't spawn it dynamically like you can on Windows. You have to start DF from the commandline, and the terminal from which you ran ./dwarfort becomes the terminal console. This should be a familiar process to many Linux users (most Linux commands work this way), but the change is jarring if you're not expecting it. We're also looking into providing a virtual console that doesn't depend on an existing system console so you can still get a console even if you run from Steam, but that work is far from being completed.

You can still launch DFHack from Steam if you want to. Many tools log information and errors to the console, though, so if you run into strange issues, it might be useful to try running from the commandline to see if there is diagnostic output there that can help you.

PSAs

As always, remember that, just like the vanilla DF game, DFHack tools can also have bugs. It is a good idea to save often and keep backups of the forts that you care about.

Many DFHack tools that worked in previous (pre-Steam) versions of DF have not been updated yet and are marked with the "unavailable" tag in their docs. If you try to run them, they will show a warning and exit immediately. You can run the command again to override the warning (though of course the tools may not work). We make no guarantees of reliability for the tools that are marked as "unavailable".

The in-game interface for running DFHack commands (gui/launcher) will not show "unavailable" tools by default. You can still run them if you know their names, or you can turn on dev mode by hitting Ctrl-D while in gui/launcher and they will be added to the autocomplete list. Some tools do not compile yet and are not available at all, even when in dev mode.

If you see a tool complaining about the lack of a cursor, know that it's referring to the keyboard cursor (which used to be the only real option in Dwarf Fortress). You can enable the keyboard cursor by entering mining mode or selecting the dump/forbid tool and hitting Alt-K (the DFHack keybinding for toggle-kbd-cursor. We're working on making DFHack tools more mouse-aware and accessible so this step isn't necessary in the future.

Hide tutorial popups

Once you've played a few forts, you probably don't need the tutorial popups that assault you when you open certain screens. Enable hide-tutorials in the System tab of gui/control-panel and never be bothered by them again!

See inside bins when selecting trade goods

The "Bring goods to trade depot" screen can now see inside bins, and you can select individual items within bins for trade instead of the entire bin, if you so choose. You can also search for contents within bins, even when in "bring the bin" mode. For example, you can find the "Gem bin"s that contain rubies by searching for "ruby".

Search and sort for squad assignment screen

The squad assignment screen was overhauled since the last beta in response to lots of great feedback. Thank you to all who responded with opinions and suggestions and helped us make this screen better!

The default sort is now "melee effectiveness", which takes both weapon skill and physical attributes into account.

Thanks to research into combat mechanics by community contributor Halifay, you can also sort by melee and ranged "potential", which predicts how effective a unit could become in the future, given adequate training.

There are also configurable filters to show or hide units in other squads, appointed/elected officials (like your manager, high priests, and doctors), and nobility.

Of course, if you know exactly who you're looking for, you can also search for units by name. Searching for skills was removed because it was too confusing. Sorting by skills is still available, though.

(These notes are cumulative with the previous beta and represent all changes since the last stable release)

New Tools

• devel/scan-vtables: Scan and dump likely vtable addresses (for memory research)
• hide-interface: hide the vanilla UI elements for clean screenshots or laid-back fortress observing
• hide-tutorials: hide the DF tutorial popups; enable in the System tab of gui/control-panel

• sort: search and sort for squad assignment screen
• zone: advanced unit assignment screens for cages, restraints, and pits/ponds

Fixes

• Core:
  • reload scripts in mods when a world is unloaded and immediately loaded again
  • fix text getting added to DFHack text entry widgets when Alt- or Ctrl- keys are hit
• caravan:
  • corrected prices for cages that have units inside of them
  • Correct price adjustment values in trade agreement details screen
  • Apply both import and export trade agreement price adjustments to items being both bought or sold to align with how vanilla DF calculates prices
  • cancel any active TradeAtDepot jobs if all caravans are instructed to leave
• emigration:
  • fix errors loading forts after dwarves assigned to work details or workshops have emigrated
  • fix citizens sometimes "emigrating" to the fortress site
• fix/retrieve-units: fix retrieved units sometimes becoming duplicated on the map

• caravan: optionally display items within bins in bring goods to depot screen
• devel/lsmem: added support for filtering by memory addresses and filenames
• gui/gm-editor:
  • hold down shift and right click to exit, regardless of how many substructures deep you are
  • display in the title bar whether the editor window is scanning for live updates
• hotkeys: don't display DFHack logo in legends mode since it covers up important interface elements. the Ctrl-Shift-C hotkey to bring up the menu and the mouseover hotspot still function, though.
• quickfort: linked stockpiles and workshops can now be specified by ID instead of only by name. this is mostly useful when dynamically generating blueprints and applying them via the quickfort API
• sort: animals are now sortable by race on the assignment screens
• suspendmanager: display a different color for jobs suspended by suspendmanager

API

• RemoteFortressReader: add a force_reload option to the GetBlockList RPC API to return blocks regardless of whether they have changed since the last request
• Gui: getAnyStockpile and getAnyCivzone (along with their getSelected variants) now work through layers of ZScreens. This means that they will still return valid results even if a DFHack tool window is in the foereground.
• Items::getValue(): remove caravan_buying parameter since the identity of the selling party doesn't actually affect the item value
• Units: new animal propery check functions isMarkedForTraining(unit), isMarkedForTaming(unit), isMarkedForWarTraining(unit), and isMarkedForHuntTraining(unit)

Lua

• dfhack.gui: new getAnyCivZone and getAnyStockpile functions; also behavior of getSelectedCivZone and getSelectedStockpile functions has changes as per the related API notes
• dfhack.items.getValue(): remove caravan_buying param as per C++ API change
• dfhack.screen.readTile(): now populates extended tile property fields (like top_of_text) in the returned Pen object
• dfhack.units: new animal propery check functions isMarkedForTraining(unit), isMarkedForTaming(unit), isMarkedForWarTraining(unit), and isMarkedForHuntTraining(unit)
• new(): improved error handling so that certain errors that were previously uncatchable (creating objects with members with unknown vtables) are now catchable with pcall()
• widgets.BannerPanel: panel with distinctive border for marking DFHack UI elements on otherwise vanilla screens
• widgets.Panel: new functions to override instead of setting corresponding properties (useful when subclassing instead of just setting attributes): onDragBegin, onDragEnd, onResizeBegin, onResizeEnd
