.. dfhack-tool::
    :summary: Place magma, water or obsidian.
    :tags: adventure fort armok map

.. dfhack-command:: liquids-here
    :summary: Spawn liquids on the selected tile.

Place magma, water or obsidian.  See `gui/liquids` for an in-game interface for
this functionality.

Also, if you only want to add or remove water or magma from a single tile, the
`source` script may be easier to use.

Usage
-----

``liquids``
    Start the interactive terminal settings interpreter. This command must be
    called from the DFHack terminal and not from any in-game interface.
``liquids-here``
    Run the liquid spawner with the current/last settings made in ``liquids``
    (if no settings in ``liquids`` were made, then it paints a point of 7/7
    magma by default). This command is intended to be used as keybinding, and it
    requires an active in-game cursor.

.. warning::

    Spawning and deleting liquids can mess up pathing data and temperatures
    (creating heat traps). You've been warned.

Interactive interpreter
-----------------------

The interpreter replaces the normal dfhack command line and can't be used from a
hotkey. Settings will be remembered as long as dfhack runs. It is intended for
use in combination with the command ``liquids-here`` (which *can* be bound to a
hotkey).

You can enter the following commands at the prompt.
