DFHack is a Dwarf Fortress memory access library and a set of basic tools that use it. Tools come in the form of plugins or (not yet) external tools. It is an attempt to unite the various ways tools access DF memory and allow for easier development of new tools.

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

Releases can be downloaded from here: https://github.com/peterix/dfhack/downloads

All new releases are announced in the bay12 thread: http://tinyurl.com/dfhack-ng

DFHack works on Windows XP, Vista, 7 or any modern Linux distribution. OSX is not supported due to lack of developers with a Mac.

Currently, versions 0.34.08 - 0.34.11 are supported. If you need DFHack for older versions, look for older releases.

On Windows, you have to use the SDL version of DF.

It is possible to use the Windows DFHack under wine/OSX.

Installing DFhack involves copying files into your DF folder. Copy the files from a release archive so that:

• On Windows, SDL.dll is replaced
• On Linux, the 'dfhack' script is placed in the same folder as the 'df' script

Uninstalling is basically the same, in reverse:

• On Windows, first delete SDL.dll and rename SDLreal.dll to SDL.dll. Then remove the other DFHack files
• On Linux, Remove the DFHack files.

The stonesense plugin might require some additional libraries on Linux.

If any of the plugins or dfhack itself refuses to load, check the stderr.log file created in your DF folder.

DFHack basically extends what DF can do with something similar to the drop-down console found in Quake engine games. On Windows, this is a separate command line window. On linux, the terminal used to launch the dfhack script is taken over (so, make sure you start from a terminal). Basic interaction with dfhack involves entering commands into the console. For some basic instroduction, use the 'help' command. To list all possible commands, use the 'ls' command. Many commands have their own help or detailed description. You can use 'command help' or 'command ?' to show that.

The command line has some nice line editing capabilities, including history that's preserved between different runs of DF (use up/down keys to go through the history).

The second way to interact with DFHack is to bind the available commands to in-game hotkeys. The old way to do this is via the hotkey/zoom menu (normally opened with the 'h' key). Binding the commands is done by assigning a command as a hotkey name (with 'n').

A new and more flexible way is the keybinding command in the dfhack console. However, bindings created this way are not automatically remembered between runs of the game, so it becomes necessary to use the dfhack.init file to ensure that they are re-created every time it is loaded.

Interactive commands like 'liquids' cannot be used as hotkeys.

Most of the commands come from plugins. Those reside in 'hack/plugins/'.

First, don't panic :) Second, dfhack keeps a few log files in DF's folder - stderr.log and stdout.log. You can look at those and possibly find out what's happening. If you found a bug, you can either report it in the bay12 DFHack thread, the issues tracker on github, contact me (peterix@gmail.com) or visit the #dfhack IRC channel on freenode.

If your DF folder contains a file named dfhack.init, its contents will be run every time you start DF. This allows setting up keybindings. An example file is provided as dfhack.init-example - you can tweak it and rename to dfhack.init if you want to use this functionality.

To set keybindings, use the built-in keybinding command. Like any other command it can be used at any time from the console, but it is also meaningful in the DFHack init file.

Currently it supports any combination of Ctrl/Alt/Shift with F1-F9, or A-Z.

Possible ways to call the command:

keybinding list <key>

List bindings active for the key combination.

keybinding clear <key> <key>...

Remove bindings for the specified keys.

keybinding add <key> "cmdline" "cmdline"...

Add bindings for the specified key.

keybinding set <key> "cmdline" "cmdline"...

Clear, and then add bindings for the specified key.

The <key> parameter above has the following case-sensitive syntax:

[Ctrl-][Alt-][Shift-]KEY[@context]

where the KEY part can be F1-F9 or A-Z, and [] denote optional parts.

When multiple commands are bound to the same key combination, DFHack selects the first applicable one. Later 'add' commands, and earlier entries within one 'add' command have priority. Commands that are not specifically intended for use as a hotkey are always considered applicable.

The context part in the key specifier above can be used to explicitly restrict the UI state where the binding would be applicable. If called without parameters, the keybinding command among other things prints the current context string. Only bindings with a context tag that either matches the current context fully, or is a prefix ending at a '/' boundary would be considered for execution, i.e. for context foo/bar/baz, possible matches are any of @foo/bar/baz, @foo/bar, @foo or none.

DFHack command syntax consists of a command name, followed by arguments separated by whitespace. To include whitespace in an argument, quote it in double quotes. To include a double quote character, use \" inside double quotes.

If the first non-whitespace character of a line is #, the line is treated as a comment, i.e. a silent no-op command.

If the first non-whitespace character is :, the command is parsed in a special alternative mode: first, non-whitespace characters immediately following the : are used as the command name; the remaining part of the line, starting with the first non-whitespace character after the command name, is used verbatim as the first argument. The following two command lines are exactly equivalent:

• :foo a b "c d" e f
• foo "a b \"c d\" e f"

This is intended for commands like rb_eval that evaluate script language statements.

Almost all the commands support using the 'help <command-name>' built-in command to retrieve further help without having to look at this document. Alternatively, some accept a 'help'/'?' option on their command line.

Instantly kills DF without saving.

Forces DF to pause. This is useful when your FPS drops below 1 and you lose control of the game.

• Activate with 'forcepause 1'
• Deactivate with 'forcepause 0'

Disables pausing (both manual and automatic) with the exception of pause forced by 'reveal hell'. This is nice for digging under rivers.

Controls speedydwarf and teledwarf. Speedydwarf makes dwarves move quickly and perform tasks quickly. Teledwarf makes dwarves move instantaneously, but do jobs at the same speed.

• 'fastdwarf 0 0' disables both
• 'fastdwarf 0 1' disables speedydwarf and enables teledwarf
• 'fastdwarf 1 0' enables speedydwarf and disables teledwarf
• 'fastdwarf 1 1' enables both
• 'fastdwarf 0' disables both
• 'fastdwarf 1' enables speedydwarf and disables teledwarf

Makes the game view follow the currently highlighted unit after you exit from current menu/cursor mode. Handy for watching dwarves running around. Deactivated by moving the view manually.

Toggle between all possible positions where the idlers count can be placed.

Toggle between displaying/not displaying liquid depth as numbers.

Copies the parameters of the currently highlighted stockpile to the custom stockpile settings and switches to custom stockpile placement mode, effectively allowing you to copy/paste stockpiles easily.

Allows renaming various things.

Options:

rename squad <index> "name"

Rename squad by index to 'name'.

rename hotkey <index> "name"

Rename hotkey by index. This allows assigning longer commands to the DF hotkeys.

rename unit "nickname"

Rename a unit/creature highlighted in the DF user interface.

rename unit-profession "custom profession"

Change proffession name of the highlighted unit/creature.

rename building "name"

Set a custom name for the selected building. The building must be one of stockpile, workshop, furnace, trap, siege engine or an activity zone.

This allows taking control over your followers and other creatures in adventure mode. For example, you can make them pick up new arms and armor and equip them properly.

Usage:

• When viewing unit details, body-swaps into that unit.
• In the main adventure mode screen, reverts transient swap.

A package of different adventure mode tools (currently just one)

Usage:

list-equipped [all]

List armor and weapons equipped by your companions. If all is specified, also lists non-metal clothing.

metal-detector [all-types] [non-trader]

Reveal metal armor and weapons in shops. The options disable the checks on item type and being in shop.

Changes material of the geology layer under cursor to the specified inorganic RAW material. Can have impact on all surrounding regions, not only your embark! By default changing stone to soil and vice versa is not allowed. By default changes only the layer at the cursor position. Note that one layer can stretch across lots of z levels. By default changes only the geology which is linked to the biome under the cursor. That geology might be linked to other biomes as well, though. Mineral veins and gem clusters will stay on the map. Use 'changevein' for them.

tl;dr: You will end up with changing quite big areas in one go, especially if you use it in lower z levels. Use with care.

Options:

all_biomes

Change selected layer for all biomes on your map. Result may be undesirable since the same layer can AND WILL be on different z-levels for different biomes. Use the tool 'probe' to get an idea how layers and biomes are distributed on your map.

all_layers

Change all layers on your map (only for the selected biome unless 'all_biomes' is added). Candy mountain, anyone? Will make your map quite boring, but tidy.

force

Allow changing stone to soil and vice versa. !!THIS CAN HAVE WEIRD EFFECTS, USE WITH CARE!! Note that soil will not be magically replaced with stone. You will, however, get a stone floor after digging so it will allow the floor to be engraved. Note that stone will not be magically replaced with soil. You will, however, get a soil floor after digging so it could be helpful for creating farm plots on maps with no soil.

verbose

Give some details about what is being changed.

trouble

Give some advice about known problems.

Examples:

changelayer GRANITE

Convert layer at cursor position into granite.

changelayer SILTY_CLAY force

Convert layer at cursor position into clay even if it's stone.

changelayer MARBLE all_biomes all_layers

Convert all layers of all biomes which are not soil into marble.

Changes material of the vein under cursor to the specified inorganic RAW material. Only affects tiles within the current 16x16 block - for veins and large clusters, you will need to use this command multiple times.

Example:

changevein NATIVE_PLATINUM

Convert vein at cursor position into platinum ore.

Allows changing item material and base quality. By default the item currently selected in the UI will be changed (you can select items in the 'k' list or inside containers/inventory). By default change is only allowed if materials is of the same subtype (for example wood<->wood, stone<->stone etc). But since some transformations work pretty well and may be desired you can override this with 'force'. Note that some attributes will not be touched, possibly resulting in weirdness. To get an idea how the RAW id should look like, check some items with 'info'. Using 'force' might create items which are not touched by crafters/haulers.

Options:

info

Don't change anything, print some info instead.

here

Change all items at the cursor position. Requires in-game cursor.

material, m

Change material. Must be followed by valid material RAW id.

quality, q

Change base quality. Must be followed by number (0-5).

force

Ignore subtypes, force change to new material.

Examples:

changeitem m INORGANIC:GRANITE here

Change material of all items under the cursor to granite.

changeitem q 5

Change currently selected item to masterpiece quality.

Allows listing all the vermin colonies on the map and optionally turning them into honey bee colonies.

Options:

bees

turn colonies into honey bee colonies

Removes all ramps designated for removal from the map. This is useful for replicating the old channel digging designation. It also removes any and all 'down ramps' that can remain after a cave-in (you don't have to designate anything for that to happen).

Enables management of map features.

• Discovering a magma feature (magma pool, volcano, magma sea, or curious underground structure) permits magma workshops and furnaces to be built.
• Discovering a cavern layer causes plants (trees, shrubs, and grass) from that cavern to grow within your fortress.

Options:

list

Lists all map features in your current embark by index.

show X

Marks the selected map feature as discovered.

hide X

Marks the selected map feature as undiscovered.

Allows adding magma, water and obsidian to the game. It replaces the normal dfhack command line and can't be used from a hotkey. Settings will be remembered as long as dfhack runs. Intended for use in combination with the command liquids-here (which can be bound to a hotkey).

For more information, refer to the command's internal help.

Run the liquid spawner with the current/last settings made in liquids (if no settings in liquids were made it paints a point of 7/7 magma by default).

Intended to be used as keybinding. Requires an active in-game cursor.

Can be used for painting map tiles and is an interactive command, much like liquids.

The tool works with two set of options and a brush. The brush determines which tiles will be processed. First set of options is the filter, which can exclude some of the tiles from the brush by looking at the tile properties. The second set of options is the paint - this determines how the selected tiles are changed.

Both paint and filter can have many different properties including things like general shape (WALL, FLOOR, etc.), general material (SOIL, STONE, MINERAL, etc.), state of 'designated', 'hidden' and 'light' flags.

The properties of filter and paint can be partially defined. This means that you can for example do something like this:

filter material STONE
filter shape FORTIFICATION
paint shape FLOOR

This will turn all stone fortifications into floors, preserving the material.

Or this: :

filter shape FLOOR
filter material MINERAL
paint shape WALL

Turning mineral vein floors back into walls.

The tool also allows tweaking some tile flags:

Or this:

paint hidden 1
paint hidden 0

This will hide previously revealed tiles (or show hidden with the 0 option).

Any paint or filter option (or the entire paint or filter) can be disabled entirely by using the ANY keyword:

paint hidden ANY
paint shape ANY
filter material any
filter shape any
filter any

You can use several different brushes for painting tiles:

• Point. (point)
• Rectangular range. (range)
• A column ranging from current cursor to the first solid tile above. (column)
• DF map block - 16x16 tiles, in a regular grid. (block)

Example:

range 10 10 1

This will change the brush to a rectangle spanning 10x10 tiles on one z-level. The range starts at the position of the cursor and goes to the east, south and up.

For more details, see the 'help' command while using this.

Runs tiletypes commands, separated by ;. This makes it possible to change tiletypes modes from a hotkey.

Apply the current tiletypes options at the in-game cursor position, including the brush. Can be used from a hotkey.

Apply the current tiletypes options at the in-game cursor position to a single tile. Can be used from a hotkey.

Fills all the adamantine veins again. Veins that were empty will be filled in too, but might still trigger a demon invasion (this is a known bug).

A tool for getting rid of trees and shrubs. By default, it only kills a tree/shrub under the cursor. The plants are turned into ashes instantly.

Options:

shrubs

affect all shrubs on the map

trees

affect all trees on the map

all

affect every plant!

Makes all saplings present on the map grow into trees (almost) instantly.

Very similar to extirpate, but additionally sets the plants on fire. The fires can and will spread ;)

Regrows grass. Not much to it ;)

Prints the current weather map by default.

Also lets you change the current weather to 'clear sky', 'rainy' or 'snowing'.

Options:

snow

make it snow everywhere.

rain

make it rain.

clear

clear the sky.

Checks a single map tile or the whole map/world for cursed creatures (ghosts, vampires, necromancers, werebeasts, zombies).

With an active in-game cursor only the selected tile will be observed. Without a cursor the whole map will be checked.

By default cursed creatures will be only counted in case you just want to find out if you have any of them running around in your fort. Dead and passive creatures (ghosts who were put to rest, killed vampires, ...) are ignored. Undead skeletons, corpses, bodyparts and the like are all thrown into the curse category "zombie". Anonymous zombies and resurrected body parts will show as "unnamed creature".

Options:

detail

Print full name, date of birth, date of curse and some status info (some vampires might use fake identities in-game, though).

nick

Set the type of curse as nickname (does not always show up in-game, some vamps don't like nicknames).

all

Include dead and passive cursed creatures (can result in a quite long list after having FUN with necromancers).

verbose

Print all curse tags (if you really want to know it all).

Examples:

cursecheck detail all

Give detailed info about all cursed creatures including deceased ones (no in-game cursor).

cursecheck nick

Give a nickname all living/active cursed creatures on the map(no in-game cursor).

A tool for checking how many tiles contain flowing liquids. If you suspect that your magma sea leaks into HFS, you can use this tool to be sure without revealing the map.

Can be used to determine tile properties like temperature.

Prints a big list of all the present minerals and plants. By default, only the visible part of the map is scanned.

Options:

all

Scan the whole map, as if it was revealed.

value

Show material value in the output. Most useful for gems.

hell

Show the Z range of HFS tubes. Implies 'all'.

If prospect is called during the embark selection screen, it displays an estimate of layer stone availability.

Options:

all

Also estimate vein mineral amounts.

This reveals the map. By default, HFS will remain hidden so that the demons don't spawn. You can use 'reveal hell' to reveal everything. With hell revealed, you won't be able to unpause until you hide the map again. If you really want to unpause with hell revealed, use 'reveal demons'.

Reveal also works in adventure mode, but any of its effects are negated once you move. When you use it this way, you don't need to run 'unreveal'.

Reverts the effects of 'reveal'.

Switches between 'reveal' and 'unreveal'.

This command will hide the whole map and then reveal all the tiles that have a path to the in-game cursor.

When you use reveal, it saves information about what was/wasn't visible before revealing everything. Unreveal uses this information to hide things again. This command throws away the information. For example, use in cases where you abandoned with the fort revealed and no longer want the data.

Shows all items needed for the currently active strange mood.

Miscellaneous burrow control. Allows manipulating burrows and automated burrow expansion while digging.

Options:

enable feature ...

Enable features of the plugin.

disable feature ...

Disable features of the plugin.

clear-unit burrow burrow ...

Remove all units from the burrows.

clear-tiles burrow burrow ...

Remove all tiles from the burrows.

set-units target-burrow src-burrow ...

Clear target, and adds units from source burrows.

add-units target-burrow src-burrow ...

Add units from the source burrows to the target.

remove-units target-burrow src-burrow ...

Remove units in source burrows from the target.

set-tiles target-burrow src-burrow ...

Clear target and adds tiles from the source burrows.

add-tiles target-burrow src-burrow ...

Add tiles from the source burrows to the target.

remove-tiles target-burrow src-burrow ...

Remove tiles in source burrows from the target.

For these three options, in place of a source burrow it is possible to use one of the following keywords: ABOVE_GROUND, SUBTERRANEAN, INSIDE, OUTSIDE, LIGHT, DARK, HIDDEN, REVEALED

Features:

auto-grow

When a wall inside a burrow with a name ending in '+' is dug out, the burrow is extended to newly-revealed adjacent walls. This final '+' may be omitted in burrow name args of commands above. Digging 1-wide corridors with the miner inside the burrow is SLOW.

Designates a whole vein for digging. Requires an active in-game cursor placed over a vein tile. With the 'x' option, it will traverse z-levels (putting stairs between the same-material tiles).

A permanent alias for 'digv x'.

Designates layer stone for digging. Requires an active in-game cursor placed over a layer stone tile. With the 'x' option, it will traverse z-levels (putting stairs between the same-material tiles). With the 'undo' option it will remove the dig designation instead (if you realize that digging out a 50 z-level deep layer was not such a good idea after all).

A permanent alias for 'digl x'.

This command can be used for exploratory mining.

See: http://df.magmawiki.com/index.php/DF2010:Exploratory_mining

There are two variables that can be set: pattern and filter.

Patterns:

diag5

diagonals separated by 5 tiles

diag5r

diag5 rotated 90 degrees

ladder

A 'ladder' pattern

ladderr

ladder rotated 90 degrees

clear

Just remove all dig designations

cross

A cross, exactly in the middle of the map.

Filters:

all

designate whole z-level

hidden

designate only hidden tiles of z-level (default)

designated

Take current designation and apply pattern to it.

After you have a pattern set, you can use 'expdig' to apply it again.

Examples:

designate the diagonal 5 patter over all hidden tiles:

• expdig diag5 hidden

apply last used pattern and filter:

• expdig

Take current designations and replace them with the ladder pattern:

• expdig ladder designated

A command for easy designation of filled and hollow circles. It has several types of options.

Shape:

hollow

Set the circle to hollow (default)

filled

Set the circle to filled

#

Diameter in tiles (default = 0, does nothing)

Action:

set

Set designation (default)

unset

Unset current designation

invert

Invert designations already present

Designation types:

dig

Normal digging designation (default)

ramp

Ramp digging

ustair

Staircase up

dstair

Staircase down

xstair

Staircase up/down

chan

Dig channel

After you have set the options, the command called with no options repeats with the last selected parameters.

Examples:

• 'digcircle filled 3' = Dig a filled circle with radius = 3.
• 'digcircle' = Do it again.

For every tile on the map of the same vein type as the selected tile, this command designates it to have the same designation as the selected tile. If the selected tile has no designation, they will be dig designated. If an argument is given, the designation of the selected tile is ignored, and all appropriate tiles are set to the specified designation.

Options:

dig

channel

ramp

updown

up/down stairs

up

up stairs

down

down stairs

clear

clear designation

Set traffic designations using flood-fill starting at the cursor.

Traffic Type Codes:

H

High Traffic

N

Normal Traffic

L

Low Traffic

R

Restricted Traffic

Other Options:

X

Fill accross z-levels.

B

Include buildings and stockpiles.

P

Include empty space.

Example:

'filltraffic H' - When used in a room with doors, it will set traffic to HIGH in just that room.

Set traffic designations for every single tile of the map (useful for resetting traffic designations).

Traffic Type Codes:

H

High Traffic

N

Normal Traffic

L

Low Traffic

R

Restricted Traffic

Example:

'alltraffic N' - Set traffic to 'normal' for all tiles.

This tool allows plant gathering and tree cutting by RAW ID. Specify the types of trees to cut down and/or shrubs to gather by their plant names, separated by spaces.

Options:

-t

Select trees only (exclude shrubs)

-s

Select shrubs only (exclude trees)

-c

Clear designations instead of setting them

-x

Apply selected action to all plants except those specified (invert selection)

Specifying both -t and -s will have no effect. If no plant IDs are specified, all valid plant IDs will be listed.

Cleans all the splatter that get scattered all over the map, items and creatures. In an old fortress, this can significantly reduce FPS lag. It can also spoil your !!FUN!!, so think before you use it.

Options:

map

Clean the map tiles. By default, it leaves mud and snow alone.

units

Clean the creatures. Will also clean hostiles.

items

Clean all the items. Even a poisoned blade.

Extra options for 'map':

mud

Remove mud in addition to the normal stuff.

snow

Also remove snow coverings.

Works like 'clean map snow mud', but only for the tile under the cursor. Ideal if you want to keep that bloody entrance 'clean map' would clean up.

This utility lets you quickly move all items designated to be dumped. Items are instantly moved to the cursor position, the dump flag is unset, and the forbid flag is set, as if it had been dumped normally. Be aware that any active dump item tasks still point at the item.

Cursor must be placed on a floor tile so the items can be dumped there.

Options:

destroy

Destroy instead of dumping. Doesn't require a cursor.

destroy-here

Destroy items only under the cursor.

visible

Only process items that are not hidden.

hidden

Only process hidden items.

forbidden

Only process forbidden items (default: only unforbidden).

Destroy items marked for dumping under cursor. Identical to autodump destroy-here, but intended for use as keybinding.

Destroy the selected item. The item may be selected in the 'k' list, or inside a container. If called again before the game is resumed, cancels destroy.

Confiscates items owned by dwarfs. By default, owned food on the floor and rotten items are confistacted and dumped.

Options:

all

confiscate all owned items

scattered

confiscated and dump all items scattered on the floor

x

confiscate/dump items with wear level 'x' and more

X

confiscate/dump items with wear level 'X' and more

dryrun

a dry run. combine with other options to see what will happen without it actually happening.

Example:

cleanowned scattered X

This will confiscate rotten and dropped food, garbage on the floors and any worn items with 'X' damage and above.

This utility removes water from all buckets in your fortress, allowing them to be safely used for making lye.

Up to version 0.31.12, Elves only sent Diplomats to your fortress to propose tree cutting quotas due to a bug; once that bug was fixed, Elves stopped caring about excess tree cutting. This command adds a Diplomat position to all Elven civilizations, allowing them to negotiate tree cutting quotas (and allowing you to violate them and potentially start wars) in case you haven't already modified your raws accordingly.

This command adds the Guild Representative position to all Human civilizations, allowing them to make trade agreements (just as they did back in 0.28.181.40d and earlier) in case you haven't already modified your raws accordingly.

Removes invalid references to mineral inclusions and restores missing ones. Use this if you broke your embark with tools like tiletypes, or if you accidentally placed a construction on top of a valuable mineral floor.

Contains various tweaks for minor bugs.

One-shot subcommands:

clear-missing

Remove the missing status from the selected unit. This allows engraving slabs for ghostly, but not yet found, creatures.

clear-ghostly

Remove the ghostly status from the selected unit and mark it as dead. This allows getting rid of bugged ghosts which do not show up in the engraving slab menu at all, even after using clear-missing. It works, but is potentially very dangerous - so use with care. Probably (almost certainly) it does not have the same effects like a proper burial. You've been warned.

fixmigrant

Remove the resident/merchant flag from the selected unit. Intended to fix bugged migrants/traders who stay at the map edge and don't enter your fort. Only works for dwarves (or generally the player's race in modded games). Do NOT abuse this for 'real' caravan merchants (if you really want to kidnap them, use 'tweak makeown' instead, otherwise they will have their clothes set to forbidden etc).

makeown

Force selected unit to become a member of your fort. Can be abused to grab caravan merchants and escorts, even if they don't belong to the player's race. Foreign sentients (humans, elves) can be put to work, but you can't assign rooms to them and they don't show up in DwarfTherapist because the game treats them like pets. Grabbing draft animals from a caravan can result in weirdness (animals go insane or berserk and are not flagged as tame), but you are allowed to mark them for slaughter. Grabbing wagons results in some funny spam, then they are scuttled.

Subcommands that persist until disabled or DF quit:

stable-cursor

Saves the exact cursor position between t/q/k/d/etc menus of dwarfmode.

patrol-duty

Makes Train orders not count as patrol duty to stop unhappy thoughts. Does NOT fix the problem when soldiers go off-duty (i.e. civilian).

readable-build-plate

Fixes rendering of creature weight limits in pressure plate build menu.

stable-temp

Fixes performance bug 6012 by squashing jitter in temperature updates. In very item-heavy forts with big stockpiles this can improve FPS by 50-100%

fast-heat

Further improves temperature update performance by ensuring that 1 degree of item temperature is crossed in no more than specified number of frames when updating from the environment temperature. This reduces the time it takes for stable-temp to stop updates again when equilibrium is disturbed.

fix-dimensions

Fixes subtracting small amount of thread/cloth/liquid from a stack by splitting the stack and subtracting from the remaining single item. This is a necessary addition to the binary patch in bug 808.

advmode-contained

Works around bug 6202, i.e. custom reactions with container inputs in advmode. The issue is that the screen tries to force you to select the contents separately from the container. This forcefully skips child reagents.

fast-trade

Makes Shift-Enter in the Move Goods to Depot and Trade screens select the current item (fully, in case of a stack), and scroll down one line.

military-stable-assign

Preserve list order and cursor position when assigning to squad, i.e. stop the rightmost list of the Positions page of the military screen from constantly resetting to the top.

military-color-assigned

Color squad candidates already assigned to other squads in brown/green to make them stand out more in the list.

This command allows you to mark the map as 'monster lair', preventing item scatter on abandon. When invoked as 'lair reset', it does the opposite.

Unlike reveal, this command doesn't save the information about tiles - you won't be able to restore state of real monster lairs using 'lair reset'.

Options:

lair

Mark the map as monster lair

lair reset

Mark the map as ordinary (not lair)

This command lets you see and change the game mode directly. Not all combinations are good for every situation and most of them will produce undesirable results. There are a few good ones though.

I take no responsibility of anything that happens as a result of using this tool

An isometric visualizer that runs in a second window. This requires working graphics acceleration and at least a dual core CPU (otherwise it will slow down DF).

All the data resides in the 'stonesense' directory. For detailed instructions, see stonesense/README.txt

Compatible with Windows > XP SP3 and most modern Linux distributions.

Older versions, support and extra graphics can be found in the bay12 forum thread: http://www.bay12forums.com/smf/index.php?topic=43260.0

Some additional resources: http://df.magmawiki.com/index.php/Utility:Stonesense/Content_repository

Export the current loaded map as a file. This will be eventually usable with visualizers.

Export dwarves to RuneSmith-compatible XML.

Command for general job query and manipulation.

Options:

no extra options

Print details of the current job. The job can be selected in a workshop, or the unit/jobs screen.

list

Print details of all jobs in the selected workshop.

item-material <item-idx> <material[:subtoken]>

Replace the exact material id in the job item.

item-type <item-idx> <type[:subtype]>

Replace the exact item type id in the job item.

Alter the material of the selected job.

Invoked as:

job-material <inorganic-token>

Intended to be used as a keybinding:

• In 'q' mode, when a job is highlighted within a workshop or furnace, changes the material of the job. Only inorganic materials can be used in this mode.
• In 'b' mode, during selection of building components positions the cursor over the first available choice with the matching material.

Duplicate the selected job in a workshop:

• In 'q' mode, when a job is highlighted within a workshop or furnace building, instantly duplicates the job.

Manage control of repeat jobs.

Usage:

workflow enable [option...], workflow disable [option...]

If no options are specified, enables or disables the plugin. Otherwise, enables or disables any of the following options:

• drybuckets: Automatically empty abandoned water buckets.
• auto-melt: Resume melt jobs when there are objects to melt.

workflow jobs

List workflow-controlled jobs (if in a workshop, filtered by it).

workflow list

List active constraints, and their job counts.

workflow count <constraint-spec> <cnt-limit> [cnt-gap], workflow amount <constraint-spec> <cnt-limit> [cnt-gap]

Set a constraint. The first form counts each stack as only 1 item.

workflow unlimit <constraint-spec>

Delete a constraint.

When the plugin is enabled, it protects all repeat jobs from removal. If they do disappear due to any cause, they are immediately re-added to their workshop and suspended.

In addition, when any constraints on item amounts are set, repeat jobs that produce that kind of item are automatically suspended and resumed as the item amount goes above or below the limit. The gap specifies how much below the limit the amount has to drop before jobs are resumed; this is intended to reduce the frequency of jobs being toggled.

Keep metal bolts within 900-1000, and wood/bone within 150-200. :

workflow amount AMMO:ITEM_AMMO_BOLTS/METAL 1000 100
workflow amount AMMO:ITEM_AMMO_BOLTS/WOOD,BONE 200 50

Keep the number of prepared food & drink stacks between 90 and 120 :

workflow count FOOD 120 30
workflow count DRINK 120 30

Make sure there are always 25-30 empty bins/barrels/bags. :

workflow count BIN 30
workflow count BARREL 30
workflow count BOX/CLOTH,SILK,YARN 30

Make sure there are always 15-20 coal and 25-30 copper bars. :

workflow count BAR//COAL 20
workflow count BAR//COPPER 30

Collect 15-20 sand bags and clay boulders. :

workflow count POWDER_MISC/SAND 20
workflow count BOULDER/CLAY 20

Make sure there are always 80-100 units of dimple dye. :

workflow amount POWDER_MISC//MUSHROOM_CUP_DIMPLE:MILL 100 20

In order for this to work, you have to set the material of the PLANT input on the Mill Plants job to MUSHROOM_CUP_DIMPLE using the 'job item-material' command.

Tool for turning cooking of seeds and plants on/off depending on how much you have of them.

See 'seedwatch help' for detailed description.

One convenient way to use the zone tool is to bind the command 'zone assign' to a hotkey, maybe also the command 'zone set'. Place the in-game cursor over a pen/pasture or pit, use 'zone set' to mark it. Then you can select units on the map (in 'v' or 'k' mode), in the unit list or from inside cages and use 'zone assign' to assign them to their new home. Allows pitting your own dwarves, by the way.

All filters can be used together with the 'assign' command.

Restrictions: It's not possible to assign units who are inside built cages or chained because in most cases that won't be desirable anyways. It's not possible to cage owned pets because in that case the owner uncages them after a while which results in infinite hauling back and forth.

Usually you should always use the filter 'own' (which implies tame) unless you want to use the zone tool for pitting hostiles. 'own' ignores own dwarves unless you specify 'race DWARF' (so it's safe to use 'assign all own' to one big pasture if you want to have all your animals at the same place). 'egglayer' and 'milkable' should be used together with 'female' unless you have a mod with egg-laying male elves who give milk or whatever. Merchants and their animals are ignored unless you specify 'merchant' (pitting them should be no problem, but stealing and pasturing their animals is not a good idea since currently they are not properly added to your own stocks; slaughtering them should work).

Most filters can be negated (e.g. 'not grazer' -> race is not a grazer).

Using the 'nick' command you can set the same nickname for multiple units. If used without 'assign', 'all' or 'count' it will rename all units in the current default target zone. Combined with 'assign', 'all' or 'count' (and further optional filters) it will rename units matching the filter conditions.

Using the 'tocages' command you can assign units to a set of cages, for example a room next to your butcher shop(s). They will be spread evenly among available cages to optimize hauling to and butchering from them. For this to work you need to build cages and then place one pen/pasture activity zone above them, covering all cages you want to use. Then use 'zone set' (like with 'assign') and use 'zone tocages filter1 filter2 ...'. 'tocages' overwrites 'assign' because it would make no sense, but can be used together with 'nick' or 'remnick' and all the usual filters.

zone assign all own ALPACA minage 3 maxage 10

Assign all own alpacas who are between 3 and 10 years old to the selected pasture.

zone assign all own caged grazer nick ineedgrass

Assign all own grazers who are sitting in cages on stockpiles (e.g. after buying them from merchants) to the selected pasture and give them the nickname 'ineedgrass'.

zone assign all own not grazer not race CAT

Assign all own animals who are not grazers, excluding cats.

zone assign count 5 own female milkable

Assign up to 5 own female milkable creatures to the selected pasture.

zone assign all own race DWARF maxage 2

Throw all useless kids into a pit :)

zone nick donttouchme

Nicknames all units in the current default zone or cage to 'donttouchme'. Mostly intended to be used for special pastures or cages which are not marked as rooms you want to protect from autobutcher.

zone tocages count 50 own tame male not grazer

Stuff up to 50 owned tame male animals who are not grazers into cages built on the current default zone.

Assigns unpastured female egg-layers to nestbox zones. Requires that you create pen/pasture zones above nestboxes. If the pen is bigger than 1x1 the nestbox must be in the top left corner. Only 1 unit will be assigned per pen, regardless of the size. The age of the units is currently not checked, most birds grow up quite fast. Egglayers who are also grazers will be ignored, since confining them to a 1x1 pasture is not a good idea. Only tame and domesticated own units are processed since pasturing half-trained wild egglayers could destroy your neat nestbox zones when they revert to wild. When called without options autonestbox will instantly run once.

Options:

start

Start running every X frames (df simulation ticks). Default: X=6000, which would be every 60 seconds at 100fps.

stop

Stop running automatically.

sleep

Must be followed by number X. Changes the timer to sleep X frames between runs.

Assigns lifestock for slaughter once it reaches a specific count. Requires that you add the target race(s) to a watch list. Only tame units will be processed.

Named units will be completely ignored (to protect specific animals from autobutcher you can give them nicknames with the tool 'rename unit' for single units or with 'zone nick' to mass-rename units in pastures and cages).

Creatures trained for war or hunting will be ignored as well.

Creatures assigned to cages will be ignored if the cage is defined as a room (to avoid butchering unnamed zoo animals).

Once you have too much adults, the oldest will be butchered first. Once you have too much kids, the youngest will be butchered first. If you don't set any target count the following default will be used: 1 male kid, 5 female kids, 1 male adult, 5 female adults.

Options:

start

Start running every X frames (df simulation ticks). Default: X=6000, which would be every 60 seconds at 100fps.

stop

Stop running automatically.

sleep

Must be followed by number X. Changes the timer to sleep X frames between runs.

watch R

Start watching a race. R can be a valid race RAW id (ALPACA, BIRD_TURKEY, etc) or a list of ids seperated by spaces or the keyword 'all' which affects all races on your current watchlist.

unwatch R

Stop watching race(s). The current target settings will be remembered. R can be a list of ids or the keyword 'all'.

forget R

Stop watching race(s) and forget it's/their target settings. R can be a list of ids or the keyword 'all'.

autowatch

Automatically adds all new races (animals you buy from merchants, tame yourself or get from migrants) to the watch list using default target count.

noautowatch

Stop auto-adding new races to the watchlist.

list

Print the current status and watchlist.

list_export

Print status and watchlist in a format which can be used to import them to another savegame (see notes).

target fk mk fa ma R

Set target count for specified race(s). fk = number of female kids, mk = number of male kids, fa = number of female adults, ma = number of female adults. R can be a list of ids or the keyword 'all' or 'new'. R = 'all': change target count for all races on watchlist and set the new default for the future. R = 'new': don't touch current settings on the watchlist, only set the new default for future entries.

example

Print some usage examples.

Examples:

You want to keep max 7 kids (4 female, 3 male) and max 3 adults (2 female, 1 male) of the race alpaca. Once the kids grow up the oldest adults will get slaughtered. Excess kids will get slaughtered starting with the youngest to allow that the older ones grow into adults. Any unnamed cats will be slaughtered as soon as possible. :

autobutcher target 4 3 2 1 ALPACA BIRD_TURKEY
autobutcher target 0 0 0 0 CAT
autobutcher watch ALPACA BIRD_TURKEY CAT
autobutcher start

Automatically put all new races onto the watchlist and mark unnamed tame units for slaughter as soon as they arrive in your fort. Settings already made for specific races will be left untouched. :

autobutcher target 0 0 0 0 new
autobutcher autowatch
autobutcher start

Stop watching the races alpaca and cat, but remember the target count settings so that you can use 'unwatch' without the need to enter the values again. Note: 'autobutcher unwatch all' works, but only makes sense if you want to keep the plugin running with the 'autowatch' feature or manually add some new races with 'watch'. If you simply want to stop it completely use 'autobutcher stop' instead. :

autobutcher unwatch ALPACA CAT

Note:

Settings and watchlist are stored in the savegame, so that you can have different settings for each world. If you want to copy your watchlist to another savegame you can use the command list_export: :

Load savegame where you made the settings.
Start a CMD shell and navigate to the df directory. Type the following into the shell:
dfhack-run autobutcher list_export > autobutcher.bat
Load the savegame where you want to copy the settings to, run the batch file (from the shell):
autobutcher.bat

Automatically manage dwarf labors.

When enabled, autolabor periodically checks your dwarves and enables or disables labors. It tries to keep as many dwarves as possible busy but also tries to have dwarves specialize in specific skills.

For detailed usage information, see 'help autolabor'.

Makes cats just multiply. It is not a good idea to run this more than once or twice.

This is the DFusion lua plugin system by warmist/darius, running as a DFHack plugin.

See the bay12 thread for details: http://www.bay12forums.com/smf/index.php?topic=69682.15

Confirmed working DFusion plugins:

simple_embark

allows changing the number of dwarves available on embark.

When enabled, every new negative dwarven thought will be multiplied by a factor (2 by default).

Usage:

misery enable n

enable misery with optional magnitude n. If specified, n must be positive.

misery n

same as "misery enable n"

misery enable

same as "misery enable 2"

misery disable

stop adding new negative thoughts. This will not remove existing duplicated thoughts. Equivalent to "misery 1"

misery clear

remove fake thoughts added in this session of DF. Saving makes them permanent! Does not change factor.

Lua or ruby scripts placed in the hack/scripts/ directory are considered for execution as if they were native DFHack commands. They are listed at the end of the 'ls' command output.

Note: scripts in subdirectories of hack/scripts/ can still be called, but will only be listed by ls if called as 'ls -a'. This is intended as a way to hide scripts that are obscure, developer-oriented, or should be used as keybindings.

Some notable scripts:

Scripts in this subdirectory fix various bugs and issues, some of them obscure.

• fix/dead-units

  Removes uninteresting dead units from the unit list. Doesn't seem to give any noticeable performance gain, but migrants normally stop if the unit list grows to around 3000 units, and this script reduces it back.

• fix/population-cap

  Run this after every migrant wave to ensure your population cap is not exceeded. The issue with the cap is that it is compared to the population number reported by the last caravan, so once it drops below the cap, migrants continue to come until that number is updated again.

• fix/stable-temp

  Instantly sets the temperature of all free-lying items to be in equilibrium with the environment and stops temperature updates. In order to maintain this efficient state however, use tweak stable-temp and tweak fast-heat.

• fix/item-occupancy

  Diagnoses and fixes issues with nonexistant 'items occupying site', usually caused by autodump bugs or other hacking mishaps.

Scripts that implement dialogs inserted into the main game window are put in this directory.

If called in dwarf mode, makes DF immediately auto-save the game by setting a flag normally used in seasonal auto-save.

Run setfps <number> to set the FPS cap at runtime, in case you want to watch combat in slow motion or something :)

Wakes up sleeping units, cancels breaks and stops parties either everywhere, or in the burrows given as arguments. In return, adds bad thoughts about noise, tiredness and lack of protection. Also, the units with interrupted breaks will go on break again a lot sooner. The script is intended for emergencies, e.g. when a siege appears, and all your military is partying.

Instantly grow seeds inside farming plots.

With no argument, this command list the various seed types currently in use in your farming plots. With a seed type, the script will grow 100 of these seeds, ready to be harvested. You can change the number with a 2nd argument.

For exemple, to grow 40 plump helmet spawn: :

growcrops plump 40

This script remove negative thoughts from your dwarves. Very useful against tantrum spirals.

With a selected unit in 'v' mode, will clear this unit's mind, otherwise clear all your fort's units minds.

Individual dwarf happiness may not increase right after this command is run, but in the short term your dwarves will get much more joyful. The thoughts are set to be very old, and the game will remove them soon when you unpause.

With the optional -v parameter, the script will dump the negative thoughts it removed.

Kills any unit of a given race.

With no argument, lists the available races.

With the special argument 'him', targets only the selected creature.

Any non-dead non-caged unit of the specified race gets its blood_count set to 0, which means immediate death at the next game tick. For creatures such as vampires, also set animal.vanish_countdown to 2.

An alternate mode is selected by adding a 2nd argument to the command, magma. In this case, a column of 7/7 magma is generated on top of the targets until they die (Warning: do not call on magma-safe creatures. Also, using this mode for birds is not recommanded.)

Will target any unit on a revealed tile of the map, including ambushers.

Ex:

slayrace gob

To kill a single creature, select the unit with the 'v' cursor and:

slayrace him

To purify all elves on the map with fire (may have side-effects):

slayrace elve magma

Create an infinite magma source on a tile.

This script registers a map tile as a magma source, and every 12 game ticks that tile receives 1 new unit of flowing magma.

Place the game cursor where you want to create the source (must be a flow-passable tile, and not too high in the sky) and call:

magmasource here

To add more than 1 unit everytime, call the command again.

To delete one source, place the cursor over its tile and use delete-here. To remove all placed sources, call magmasource stop.

With no argument, this command shows an help message and list existing sources.

A script to designate an area for digging according to a plan in csv format.

This script, inspired from quickfort, can designate an area for digging. Your plan should be stored in a .csv file like this:

# this is a comment 
d;d;u;d;d;skip this tile;d
d;d;d;i

Available tile shapes are named after the 'dig' menu shortcuts: d for dig, u for upstairs, d downstairs, i updown, h channel, r upward ramp, x remove designation. Unrecognized characters are ignored (eg the 'skip this tile' in the sample).

Empty lines and data after a # are ignored as comments. To skip a row in your design, use a single ;.

The script takes the plan filename, starting from the root df folder.

Similar to fastdwarf, per-creature.

To make any creature superfast, target it ingame using 'v' and:

superdwarf add

Other options available: del, clear, list.

This plugin also shortens the 'sleeping' and 'on break' periods of targets.

Remove all 'aquifer' tag from the map blocks. Irreversible.

Focus a body part ingame, and this script will display the cause of death of the creature.

These tools work by displaying dialogs or overlays in the game window, and are mostly implemented by lua scripts.

Implemented by the manipulator plugin. To activate, open the unit screen and press 'l'.

This tool implements a Dwarf Therapist-like interface within the game UI. The far left column displays the unit's Happiness (color-coded based on its value), and the right half of the screen displays each dwarf's labor settings and skill levels (0-9 for Dabbling thru Professional, A-E for Great thru Grand Master, and U-Z for Legendary thru Legendary+5). Cells with red backgrounds denote skills not controlled by labors.

Use the arrow keys or number pad to move the cursor around, holding Shift to move 10 tiles at a time.

Press the Z-Up (<) and Z-Down (>) keys to move quickly between labor/skill categories. The numpad Z-Up and Z-Down keys seek to the first or last unit in the list. Backspace seeks to the top left corner.

Press Enter to toggle the selected labor for the selected unit, or Shift+Enter to toggle all labors within the selected category.

Press the +- keys to sort the unit list according to the currently selected skill/labor, and press the */ keys to sort the unit list by Name, Profession, Happiness, or Arrival order (using Tab to select which sort method to use here).

With a unit selected, you can press the "v" key to view its properties (and possibly set a custom nickname or profession) or the "c" key to exit Manipulator and zoom to its position within your fortress.

The following mouse shortcuts are also available:

• Click on a column header to sort the unit list. Left-click to sort it in one direction (descending for happiness or labors/skills, ascending for name or profession) and right-click to sort it in the opposite direction.
• Left-click on a labor cell to toggle that labor. Right-click to move the cursor onto that cell instead of toggling it.
• Left-click on a unit's name or profession to view its properties.
• Right-click on a unit's name or profession to zoom to it.

Pressing ESC normally returns to the unit screen, but Shift-ESC would exit directly to the main dwarf mode screen.

Implemented by the gui/liquids script. To use, bind to a key and activate in the 'k' mode.

While active, use the suggested keys to switch the usual liquids parameters, and Enter to select the target area and apply changes.

Implemented by the gui/mechanims script. To use, bind to a key and activate in the 'q' mode.

Lists mechanisms connected to the building, and their links. Navigating the list centers the view on the relevant linked buildings.

To exit, press ESC or Enter; ESC recenters on the original building, while Enter leaves focus on the current one. Shift-Enter has an effect equivalent to pressing Enter, and then re-entering the mechanisms ui.

Backed by the rename plugin, the gui/rename script allows entering the desired name via a simple dialog in the game ui.

• gui/rename [building] in 'q' mode changes the name of a building.

  The selected building must be one of stockpile, workshop, furnace, trap, or siege engine. It is also possible to rename zones from the 'i' menu.

• gui/rename [unit] with a unit selected changes the nickname.
• gui/rename unit-profession changes the selected unit's custom profession name.

The building or unit options are automatically assumed when in relevant ui state.

Implemented by the gui/room-list script. To use, bind to a key and activate in the 'q' mode, either immediately or after opening the assign owner page.

The script lists other rooms owned by the same owner, or by the unit selected in the assign list, and allows unassigning them.

These plugins, when activated via configuration UI or by detecting certain structures in RAWs, modify the game engine behavior concerning the target objects to add features not otherwise present.

The siege-engine plugin enables siege engines to be linked to stockpiles, and aimed at an arbitrary rectangular area across Z levels, instead of the original four directions. Also, catapults can be ordered to load arbitrary objects, not just stones.

Siege engines are a very interesting feature, but sadly almost useless in the current state because they haven't been updated since 2D and can only aim in four directions. This is an attempt to bring them more up to date until Toady has time to work on it. Actual improvements, e.g. like making siegers bring their own, are something only Toady can do.

The configuration front-end to the plugin is implemented by the gui/siege-engine script. Bind it to a key and activate after selecting a siege engine in 'q' mode.

The main mode displays the current target, selected ammo item type, linked stockpiles and the allowed operator skill range. The map tile color is changed to signify if it can be hit by the selected engine: green for fully reachable, blue for out of range, red for blocked, yellow for partially blocked.

Pressing 'r' changes into the target selection mode, which works by highlighting two points with Enter like all designations. When a target area is set, the engine projectiles are aimed at that area, or units within it (this doesn't actually change the original aiming code, instead the projectile trajectory parameters are rewritten as soon as it appears).

After setting the target in this way for one engine, you can 'paste' the same area into others just by pressing 'p' in the main page of this script. The area to paste is kept until you quit DF, or select another area manually.

Pressing 't' switches to a mode for selecting a stockpile to take ammo from.

Exiting from the siege engine script via ESC reverts the view to the state prior to starting the script. Shift-ESC retains the current viewport, and also exits from the 'q' mode to main menu.

The power-meter plugin implements a modified pressure plate that detects power being supplied to gear boxes built in the four adjacent N/S/W/E tiles.

The configuration front-end is implemented by the gui/power-meter script. Bind it to a key and activate after selecting Pressure Plate in the build menu.

The script follows the general look and feel of the regular pressure plate build configuration page, but configures parameters relevant to the modded power meter building.

The steam-engine plugin detects custom workshops with STEAM_ENGINE in their token, and turns them into real steam engines.

The vanilla game contains only water wheels and windmills as sources of power, but windmills give relatively little power, and water wheels require flowing water, which must either be a real river and thus immovable and limited in supply, or actually flowing and thus laggy.

Steam engines are an alternative to water reactors that actually makes sense, and hopefully doesn't lag. Also, unlike e.g. animal treadmills, it can be done just by combining existing features of the game engine in a new way with some glue code and a bit of custom logic.

The workshop needs water as its input, which it takes via a passable floor tile below it, like usual magma workshops do. The magma version also needs magma.

After constructing the building itself, machines can be connected to the edge tiles that look like gear boxes. Their exact position is extracted from the workshop raws.

In order to operate the engine, queue the Stoke Boiler job (optionally on repeat). A furnace operator will come, possibly bringing a bar of fuel, and perform it. As a result, a "boiling water" item will appear in the 't' view of the workshop.

Every such item gives 100 power, up to a limit of 300 for coal, and 500 for a magma engine. The building can host twice that amount of items to provide longer autonomous running. When the boiler gets filled to capacity, all queued jobs are suspended; once it drops back to 3+1 or 5+1 items, they are re-enabled.

While the engine is providing power, steam is being consumed. The consumption speed includes a fixed 10% waste rate, and the remaining 90% are applied proportionally to the actual load in the machine. With the engine at nominal 300 power with 150 load in the system, it will consume steam for actual 300*(10% + 90%*150/300) = 165 power.

Masterpiece mechanism and chain will decrease the mechanical power drawn by the engine itself from 10 to 5. Masterpiece barrel decreases waste rate by 4%. Masterpiece piston and pipe decrease it by further 4%, and also decrease the whole steam use rate by 10%.

The engine must be constructed using barrel, pipe and piston from fire-safe, or in the magma version magma-safe metals.

During operation weak parts get gradually worn out, and eventually the engine explodes. It should also explode if toppled during operation by a building destroyer, or a tantruming dwarf.

It should be safe to load and view engine-using fortresses from a DF version without DFHack installed, except that in such case the engines won't work. However actually making modifications to them, or machines they connect to (including by pulling levers), can easily result in inconsistent state once this plugin is available again. The effects may be as weird as negative power being generated.

This plugin makes reactions with names starting with SPATTER_ADD_ produce contaminants on the items instead of improvements. The produced contaminants are immune to being washed away by water or destroyed by the clean items command.

The plugin is intended to give some use to all those poisons that can be bought from caravans. :)

To be really useful this needs patches from bug 808, tweak fix-dimensions and tweak advmode-contained.
