The current version of DFHack has extensive support for
|
|
|
|
the Lua scripting language, providing access to:
|
|
|
|
|
|
|
|
1. Raw data structures used by the game.
|
|
|
|
2. Many C++ functions for high-level access to these
|
|
|
|
structures, and interaction with dfhack itself.
|
|
|
|
3. Some functions exported by C++ plugins.
|
|
|
|
|
|
|
|
Lua code can be used both for writing scripts, which
|
|
|
|
are treated by DFHack command line prompt almost as
|
|
|
|
native C++ commands, and invoked by plugins written in c++.
|
|
|
|
|
|
|
|
This document describes native API available to Lua in detail.

implemented by Lua files located in hack/lua/...

|
|
|
|
DF data structure wrapper
|
|
|
|
=========================
|
2012-04-02 12:00:38 -06:00
|
|
|
|
|
|
|
DF structures described by the xml files in library/xml are exported
|
|
|
|
to lua code as a tree of objects and functions under the ``df`` global,
|
|
|
|
which broadly maps to the ``df`` namespace in C++.
|
|
|
|
|
|
|
|
**WARNING**: The wrapper provides almost raw access to the memory
|
|
|
|
of the game, so mistakes in manipulating objects are as likely to
|
|
|
|
crash the game as equivalent plain C++ code would be. E.g. NULL
|
|
|
|
pointer access is safely detected, but dangling pointers aren't.
|
|
|
|
|
|
|
|
Objects managed by the wrapper can be broadly classified into the following groups:
|
|
|
|
|
|
|
|
1. Typed object pointers (references).
|
|
|
|
|
|
|
|
References represent objects in DF memory with a known type.
|
|
|
|
|
|
|
|
In addition to fields and methods defined by the wrapped type,
|
|
|
|
every reference has some built-in properties and methods.
|
|
|
|
|
|
|
|
2. Untyped pointers
|
|
|
|
|
|
|
|
Represented as lightuserdata.
|
|
|
|
|
|
|
|
In assignment to a pointer NULL can be represented either as
|
|
|
|
``nil``, or a NULL lightuserdata; reading a NULL pointer field
|
|
|
|
returns ``nil``.
|
|
|
|
|
|
|
|
3. Named types
|
|
|
|
|
|
|
|
Objects in the ``df`` tree that represent identity of struct, class,
|
|
|
|
enum and bitfield types. They host nested named types, static
|
|
|
|
methods, builtin properties & methods, and, for enums and bitfields,
|
|
|
|
the bi-directional mapping between key names and values.
|
|
|
|
|
|
|
|
4. The ``global`` object
|
|
|
|
|
|
|
|
``df.global`` corresponds to the ``df::global`` namespace, and
|
|
|
|
behaves as a mix between a named type and a reference, containing
|
|
|
|
both nested types and fields corresponding to global symbols.
|
|
|
|
|
|
|
|
In addition to the ``global`` object and top-level types the ``df``
|
|
|
|
global also contains a few global builtin utility functions.
|
|
|
|
|
|
|
|
Typed object references
|
|
|
|
=======================
|
|
|
|
|
|
|
|
The underlying primitive lua object is userdata with a metatable.
|
|
|
|
Every structured field access produces a new userdata instance.
|
|
|
|
|
|
|
|
All typed objects have the following built-in features:
|
|
|
|
|
|
|
|
* ``ref1 == ref2``, ``tostring(ref)``
|
|
|
|
|
|
|
|
References implement equality by type & pointer value, and string conversion.
|
|
|
|
|
|
|
|
* ``pairs(ref)``
|
|
|
|
|
|
|
|
Returns an iterator for the sequence of actual C++ field names
|
|
|
|
and values. Fields are enumerated in memory order. Methods and
|
|
|
|
lua wrapper properties are not included in the iteration.
|
|
|
|
|
2012-04-10 00:34:03 -06:00
|
|
|
**WARNING**: a few of the data structures (like ui_look_list)
|
|
|
|
contain unions with pointers to different types with vtables.
|
|
|
|
Using pairs on such structs is an almost sure way to crash with
|
|
|
|
an access violation.
|
|
|
|
|
2012-04-02 12:00:38 -06:00
|
|
|
* ``ref._kind``
|
|
|
|
|
|
|
|
Returns one of: ``primitive``, ``struct``, ``container``,
|
|
|
|
or ``bitfield``, as appropriate for the referenced object.
|
|
|
|
|
|
|
|
* ``ref._type``
|
|
|
|
|
|
|
|
Returns the named type object or a string that represents
|
|
|
|
the referenced object type.
|
|
|
|
|
|
|
|
* ``ref:sizeof()``
|
|
|
|
|
|
|
|
Returns *size, address*
|
|
|
|
|
|
|
|
* ``ref:new()``
|
|
|
|
|
|
|
|
Allocates a new instance of the same type, and copies data
|
|
|
|
from the current object.
|
|
|
|
|
|
|
|
* ``ref:delete()``
|
|
|
|
|
|
|
|
Destroys the object with the C++ ``delete`` operator.
|
|
|
|
If destructor is not available, returns *false*.
|
|
|
|
|
|
|
|
**WARNING**: the lua reference object remains as a dangling
|
|
|
|
pointer, like a raw C++ pointer would.
|
|
|
|
|
|
|
|
* ``ref:assign(object)``
|
|
|
|
|
|
|
|
Assigns data from object to ref. Object must either be another
|
|
|
|
ref of a compatible type, or a lua table; in the latter case
|
|
|
|
special recursive assignment rules are applied.
|
|
|
|
|
|
|
|
* ``ref:_displace(index[,step])``
|
|
|
|
|
|
|
|
Returns a new reference with the pointer adjusted by index*step.
|
|
|
|
Step defaults to the natural object size.
|
|
|
|
|
|
|
|
Primitive references
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
References of the *_kind* ``'primitive'`` are used for objects
|
|
|
|
that don't fit any of the other reference types. Such
|
|
|
|
references can only appear as a value of a pointer field,
|
|
|
|
or as a result of calling the ``_field()`` method.
|
|
|
|
|
|
|
|
They behave as structs with one field ``value`` of the right type.
|
|
|
|
|
2012-06-13 12:40:39 -06:00
|
|
|
To make working with numeric buffers easier, they also allow
|
|
|
|
numeric indices. Note that other than excluding negative values
|
|
|
|
no bound checking is performed, since buffer length is not available.
|
|
|
|
Index 0 is equivalent to the ``value`` field.
|
|
|
|
|
|
|
|
|
2012-04-02 12:00:38 -06:00
|
|
|
Struct references
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
Struct references are used for class and struct objects.
|
|
|
|
|
|
|
|
They implement the following features:
|
|
|
|
|
|
|
|
* ``ref.field``, ``ref.field = value``
|
|
|
|
|
|
|
|
Valid fields of the structure may be accessed by subscript.
|
|
|
|
|
2012-04-03 03:13:44 -06:00
|
|
|
Primitive typed fields, i.e. numbers & strings, are converted
|
|
|
|
to/from matching lua values. The value of a pointer is a reference
|
|
|
|
to the target, or nil/NULL. Complex types are represented by
|
|
|
|
a reference to the field within the structure; unless recursive
|
|
|
|
lua table assignment is used, such fields can only be read.
|
|
|
|
|
|
|
|
**NOTE:** In case of inheritance, *superclass* fields have precedence
|
2012-04-02 12:00:38 -06:00
|
|
|
over the subclass, but fields shadowed in this way can still
|
|
|
|
be accessed as ``ref['subclasstype.field']``.
|
|
|
|
This shadowing order is necessary because vtable-based classes
|
|
|
|
are automatically exposed in their exact type, and the reverse
|
|
|
|
rule would make access to superclass fields unreliable.
|
|
|
|
|
|
|
|
* ``ref._field(field)``
|
|
|
|
|
|
|
|
Returns a reference to a valid field. That is, unlike regular
|
2012-04-03 03:13:44 -06:00
|
|
|
subscript, it returns a reference to the field within the structure
|
|
|
|
even for primitive typed fields and pointers.
|
2012-04-02 12:00:38 -06:00
|
|
|
|
|
|
|
* ``ref:vmethod(args...)``
|
|
|
|
|
|
|
|
Named virtual methods are also exposed, subject to the same
|
|
|
|
shadowing rules.
|
|
|
|
|
|
|
|
* ``pairs(ref)``
|
|
|
|
|
|
|
|
Enumerates all real fields (but not methods) in memory
|
|
|
|
(= declaration) order.
|
|
|
|
|
|
|
|
Container references
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
Containers represent vectors and arrays, possibly resizable.
|
|
|
|
|
|
|
|
A container field can associate an enum to the container
|
|
|
|
reference, which allows accessing elements using string keys
|
|
|
|
instead of numerical indices.
|
|
|
|
|
|
|
|
Implemented features:
|
|
|
|
|
|
|
|
* ``ref._enum``
|
|
|
|
|
|
|
|
If the container has an associated enum, returns the matching
|
|
|
|
named type object.
|
|
|
|
|
|
|
|
* ``#ref``
|
|
|
|
|
|
|
|
Returns the *length* of the container.
|
|
|
|
|
|
|
|
* ``ref[index]``
|
|
|
|
|
|
|
|
Accesses the container element, using either a *0-based* numerical
|
|
|
|
index, or, if an enum is associated, a valid enum key string.
|
|
|
|
|
|
|
|
Accessing an invalid index is an error, but some container types
|
|
|
|
may return a default value, or auto-resize instead for convenience.
|
|
|
|
Currently this relaxed mode is implemented by df-flagarray aka BitArray.
|
|
|
|
|
|
|
|
* ``ref._field(index)``
|
|
|
|
|
|
|
|
Like with structs, returns a pointer to the array element, if possible.
|
|
|
|
Flag and bit arrays cannot return such pointer, so it fails with an error.
|
|
|
|
|
|
|
|
* ``pairs(ref)``, ``ipairs(ref)``
|
|
|
|
|
|
|
|
If the container has no associated enum, both behave identically,
|
|
|
|
iterating over numerical indices in order. Otherwise, ipairs still
|
|
|
|
uses numbers, while pairs tries to substitute enum keys whenever
|
|
|
|
possible.
|
|
|
|
|
|
|
|
* ``ref:resize(new_size)``
|
|
|
|
|
|
|
|
Resizes the container if supported, or fails with an error.
|
|
|
|
|
|
|
|
* ``ref:insert(index,item)``
|
|
|
|
|
|
|
|
Inserts a new item at the specified index. To add at the end,
|
2012-04-17 02:15:45 -06:00
|
|
|
use ``#ref``, or just ``'#'`` as index.
|
2012-04-02 12:00:38 -06:00
|
|
|
|
|
|
|
* ``ref:erase(index)``
|
|
|
|
|
|
|
|
Removes the element at the given valid index.
|
|
|
|
|
|
|
|
Bitfield references
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
Bitfields behave like special fixed-size containers.
|
2012-06-13 01:00:54 -06:00
|
|
|
Consider them to be something in between structs and
|
|
|
|
fixed-size vectors.
|
2012-04-02 12:00:38 -06:00
|
|
|
|
2012-06-13 01:00:54 -06:00
|
|
|
The ``_enum`` property points to the bitfield type.
|
2012-04-02 12:00:38 -06:00
|
|
|
Numerical indices correspond to the shift value,
|
|
|
|
and if a subfield occupies multiple bits, the
|
|
|
|
``ipairs`` order would have a gap.
|
|
|
|
|
2012-06-13 01:00:54 -06:00
|
|
|
Since currently there is no API to allocate a bitfield
|
|
|
|
object fully in GC-managed lua heap, consider using the
|
|
|
|
lua table assignment feature outlined below in order to
|
|
|
|
pass bitfield values to dfhack API functions that need
|
|
|
|
them, e.g. ``matinfo:matches{metal=true}``.
|
|
|
|
|
|
|
|
|
2012-04-02 12:00:38 -06:00
|
|
|
Named types
|
|
|
|
===========
|
|
|
|
|
|
|
|
Named types are exposed in the ``df`` tree with names identical
|
|
|
|
to the C++ version, except for the ``::`` vs ``.`` difference.
|
|
|
|
|
|
|
|
All types and the global object have the following features:
|
|
|
|
|
|
|
|
* ``type._kind``
|
|
|
|
|
|
|
|
Evaluates to one of ``struct-type``, ``class-type``, ``enum-type``,
|
|
|
|
``bitfield-type`` or ``global``.
|
|
|
|
|
|
|
|
* ``type._identity``
|
|
|
|
|
|
|
|
Contains a lightuserdata pointing to the underlying
|
|
|
|
DFHack::type_instance object.
|
|
|
|
|
|
|
|
Types excluding the global object also support:
|
|
|
|
|
|
|
|
* ``type:sizeof()``
|
|
|
|
|
|
|
|
Returns the size of an object of the type.
|
|
|
|
|
|
|
|
* ``type:new()``
|
|
|
|
|
|
|
|
Creates a new instance of an object of the type.
|
|
|
|
|
|
|
|
* ``type:is_instance(object)``
|
|
|
|
|
|
|
|
Returns true if object is same or subclass type, or a reference
|
|
|
|
to an object of same or subclass type. It is permissible to pass
|
|
|
|
nil, NULL or non-wrapper value as object; in this case the
|
|
|
|
method returns nil.
|
|
|
|
|
|
|
|
In addition to this, enum and bitfield types contain a
|
|
|
|
bi-directional mapping between key strings and values, and
|
|
|
|
also map ``_first_item`` and ``_last_item`` to the min and
|
|
|
|
max values.
|
|
|
|
|
|
|
|
Struct and class types with instance-vector attribute in the
|
|
|
|
xml have a ``type.find(key)`` function that wraps the find
|
|
|
|
method provided in C++.
|
|
|
|
|
|
|
|
Global functions
|
|
|
|
================
|
|
|
|
|
|
|
|
The ``df`` table itself contains the following functions and values:
|
|
|
|
|
|
|
|
* ``NULL``, ``df.NULL``
|
|
|
|
|
|
|
|
Contains the NULL lightuserdata.
|
|
|
|
|
|
|
|
* ``df.isnull(obj)``
|
|
|
|
|
|
|
|
Evaluates to true if obj is nil or NULL; false otherwise.
|
|
|
|
|
|
|
|
* ``df.isvalid(obj[,allow_null])``
|
|
|
|
|
|
|
|
For supported objects returns one of ``type``, ``voidptr``, ``ref``.
|
|
|
|
|
|
|
|
If *allow_null* is true, and obj is nil or NULL, returns ``null``.
|
|
|
|
|
|
|
|
Otherwise returns *nil*.
|
|
|
|
|
|
|
|
* ``df.sizeof(obj)``
|
|
|
|
|
|
|
|
For types and refs identical to ``obj:sizeof()``.
|
|
|
|
For lightuserdata returns *nil, address*
|
|
|
|
|
|
|
|
* ``df.new(obj)``, ``df.delete(obj)``, ``df.assign(obj, obj2)``
|
|
|
|
|
|
|
|
Equivalent to using the matching methods of obj.
|
|
|
|
|
|
|
|
* ``df._displace(obj,index[,step])``
|
|
|
|
|
|
|
|
For refs equivalent to the method, but also works with
|
|
|
|
lightuserdata (step is mandatory then).
|
|
|
|
|
|
|
|
* ``df.is_instance(type,obj)``
|
|
|
|
|
|
|
|
Equivalent to the method, but also allows a reference as proxy for its type.
|
2012-04-03 03:13:44 -06:00
|
|
|
|
2012-06-13 12:26:54 -06:00
|
|
|
* ``df.new(ptype[,count])``
|
|
|
|
|
|
|
|
Allocate a new instance, or an array of built-in types.
|
|
|
|
The ``ptype`` argument is a string from the following list:
|
|
|
|
``string``, ``int8_t``, ``uint8_t``, ``int16_t``, ``uint16_t``,
|
|
|
|
``int32_t``, ``uint32_t``, ``int64_t``, ``uint64_t``, ``bool``,
|
|
|
|
``float``, ``double``. All of these except ``string`` can be
|
|
|
|
used with the count argument to allocate an array.
|
|
|
|
|
|
|
|
* ``df.reinterpret_cast(type,ptr)``
|
|
|
|
|
|
|
|
Converts ptr to a ref of specified type. The type may be anything
|
|
|
|
acceptable to ``df.is_instance``. Ptr may be *nil*, a ref,
|
|
|
|
a lightuserdata, or a number.
|
|
|
|
|
|
|
|
Returns *nil* if NULL, or a ref.
|
|
|
|
|
|
|
|

Recursive table assignment
|
|
|
|
==========================
|
|
|
|
|
|
|
|
Recursive assignment is invoked when a lua table is assigned
|
|
|
|
to a C++ object or field, i.e. one of:
|
|
|
|
|
|
|
|
* ``ref:assign{...}``
|
|
|
|
* ``ref.field = {...}``
|
|
|
|
|
|
|
|
The general mode of operation is that all fields of the table
|
|
|
|
are assigned to the fields of the target structure, roughly
|
|
|
|
emulating the following code::
|
|
|
|
|
|
|
|
function rec_assign(ref,table)
|
|
|
|
for key,value in pairs(table) do
|
|
|
|
ref[key] = value
|
|
|
|
end
|
|
|
|
end
|
|
|
|
|
|
|
|
Since assigning a table to a field using = invokes the same
|
|
|
|
process, it is recursive.
|
|
|
|
|
|
|
|
There are however some variations to this process depending
|
|
|
|
on the type of the field being assigned to:
|
|
|
|
|
|
|
|
1. If the table contains an ``assign`` field, it is
|
|
|
|
applied first, using the ``ref:assign(value)`` method.
|
|
|
|
It is never assigned as a usual field.
|
|
|
|
|
|
|
|
2. When a table is assigned to a non-NULL pointer field
|
|
|
|
using the ``ref.field = {...}`` syntax, it is applied
|
|
|
|
to the target of the pointer instead.
|
|
|
|
|
|
|
|
If the pointer is NULL, the table is checked for a ``new`` field:
|
|
|
|
|
|
|
|
a. If it is *nil* or *false*, assignment fails with an error.
|
|
|
|
|
|
|
|
b. If it is *true*, the pointer is initialized with a newly
|
|
|
|
allocated object of the declared target type of the pointer.
|
|
|
|
|
|
|
|
c. Otherwise, ``table.new`` must be a named type, or an
|
|
|
|
object of a type compatible with the pointer. The pointer
|
|
|
|
is initialized with the result of calling ``table.new:new()``.
|
|
|
|
|
|
|
|
After this auto-vivification process, assignment proceeds
|
|
|
|
as if the pointer wasn't NULL.
|
|
|
|
|
|
|
|
Obviously, the ``new`` field inside the table is always skipped
|
|
|
|
during the actual per-field assignment processing.
|
|
|
|
|
|
|
|
3. If the target of the assignment is a container, a separate
|
|
|
|
rule set is used:
|
|
|
|
|
|
|
|
a. If the table contains neither ``assign`` nor ``resize``
|
|
|
|
fields, it is interpreted as an ordinary *1-based* lua
|
|
|
|
array. The container is resized to the #-size of the
|
|
|
|
table, and elements are assigned in numeric order::
|
|
|
|
|
|
|
|
ref:resize(#table);
|
|
|
|
for i=1,#table do ref[i-1] = table[i] end
|
|
|
|
|
|
|
|
b. Otherwise, ``resize`` must be *true*, *false*, or
|
|
|
|
an explicit number. If it is not false, the container
|
|
|
|
is resized. After that the usual struct-like 'pairs'
|
|
|
|
assignment is performed.
|
|
|
|
|
|
|
|
In case ``resize`` is *true*, the size is computed
|
|
|
|
by scanning the table for the largest numeric key.
|
|
|
|
|
|
|
|
This means that in order to reassign only one element of
|
|
|
|
a container using this system, it is necessary to use::
|
|
|
|
|
|
|
|
{ resize=false, [idx]=value }
|
|
|
|
|
|
|
|
Since nil inside a table is indistinguishable from missing key,
|
|
|
|
it is necessary to use ``df.NULL`` as a null pointer value.
|
|
|
|
|
|
|
|
This system is intended as a way to define a nested object
|
|
|
|
tree using pure lua data structures, and then materialize it in
|
|
|
|
C++ memory in one go. Note that if pointer auto-vivification
|
|
|
|
is used, an error in the middle of the recursive walk would
|
|
|
|
not destroy any objects allocated in this way, so the user
|
|
|
|
should be prepared to catch the error and do the necessary
|
|
|
|
cleanup.

Input & Output
|
|
|
|
--------------
|
2012-04-03 03:13:44 -06:00
|
|
|
|
|
|
|
* ``dfhack.print(args...)``
|
|
|
|
|
|
|
|
Output tab-separated args as standard lua print would do,
|
|
|
|
but without a newline.
|
|
|
|
|
|
|
|
* ``print(args...)``, ``dfhack.println(args...)``
|
|
|
|
|
|
|
|
A replacement of the standard library print function that
|
|
|
|
works with DFHack output infrastructure.
|
|
|
|
|
|
|
|
* ``dfhack.printerr(args...)``
|
|
|
|
|
|
|
|
Same as println; intended for errors. Uses red color and logs to stderr.log.
|
|
|
|
|
2012-04-04 00:40:33 -06:00
|
|
|
* ``dfhack.color([color])``
|
2012-04-03 10:02:01 -06:00
|
|
|
|
2012-04-04 00:40:33 -06:00
|
|
|
Sets the current output color. If color is *nil* or *-1*, resets to default.
|
2012-06-21 11:26:25 -06:00
|
|
|
Returns the previous color value.
|
2012-04-04 00:40:33 -06:00
|
|
|
|
|
|
|
* ``dfhack.is_interactive()``
|
|
|
|
|
|
|
|
Checks if the thread can access the interactive console and returns *true* or *false*.
|
|
|
|
|
|
|
|
* ``dfhack.lineedit([prompt[,history_filename]])``
|
|
|
|
|
|
|
|
If the thread owns the interactive console, shows a prompt
|
|
|
|
and returns the entered string. Otherwise returns *nil, error*.
|
2012-04-03 10:02:01 -06:00
|
|
|
|
2012-04-17 01:45:09 -06:00
|
|
|
Depending on the context, this function may actually yield the
|
|
|
|
running coroutine and let the C++ code release the core suspend
|
|
|
|
lock. Using an explicit ``dfhack.with_suspend`` will prevent
|
|
|
|
this, forcing the function to block on input with lock held.
|
|
|
|
|
2012-04-03 03:13:44 -06:00
|
|
|
* ``dfhack.interpreter([prompt[,env[,history_filename]]])``
|
|
|
|
|
|
|
|
Starts an interactive lua interpreter, using the specified prompt
|
|
|
|
string, global environment and command-line history file.
|
|
|
|
|
|
|
|
If the interactive console is not accessible, returns *nil, error*.

Exception handling
|
|
|
|
------------------
|
|
|
|
|
|
|
|
* ``dfhack.error(msg[,level[,verbose]])``
|
|
|
|
|
|
|
|
Throws a dfhack exception object with location and stack trace.
|
|
|
|
The verbose parameter controls whether the trace is printed by default.
|
|
|
|
|
|
|
|
* ``qerror(msg[,level])``
|
|
|
|
|
|
|
|
Calls ``dfhack.error()`` with ``verbose`` being *false*. Intended to
|
|
|
|
be used for user-caused errors in scripts, where stack traces are not
|
|
|
|
desirable.
|
|
|
|
|
|
|
|
* ``dfhack.pcall(f[,args...])``
|
|
|
|
|
|
|
|
Invokes f via xpcall, using an error function that attaches
|
|
|
|
a stack trace to the error. The same function is used by SafeCall
|
|
|
|
in C++, and dfhack.safecall.
|
|
|
|
|
|
|
|
* ``safecall(f[,args...])``, ``dfhack.safecall(f[,args...])``
|
|
|
|
|
|
|
|
Just like pcall, but also prints the error using printerr before
|
|
|
|
returning. Intended as a convenience function.
|
|
|
|
|
|
|
|
* ``dfhack.saferesume(coroutine[,args...])``
|
|
|
|
|
|
|
|
Compares to coroutine.resume like dfhack.safecall vs pcall.
|
|
|
|
|
|
|
|
* ``dfhack.exception``
|
|
|
|
|
|
|
|
Metatable of error objects used by dfhack. The objects have the
|
|
|
|
following properties:
|
|
|
|
|
|
|
|
``err.where``
|
|
|
|
The location prefix string, or *nil*.
|
|
|
|
``err.message``
|
|
|
|
The base message string.
|
|
|
|
``err.stacktrace``
|
|
|
|
The stack trace string, or *nil*.
|
|
|
|
``err.cause``
|
|
|
|
A different exception object, or *nil*.
|
|
|
|
``err.thread``
|
|
|
|
The coroutine that has thrown the exception.
|
|
|
|
``err.verbose``
|
|
|
|
Boolean, or *nil*; specifies if where and stacktrace should be printed.
|
|
|
|
``tostring(err)``, or ``err:tostring([verbose])``
|
|
|
|
Converts the exception to string.
|
|
|
|
|
|
|
|
* ``dfhack.exception.verbose``
|
|
|
|
|
|
|
|
The default value of the ``verbose`` argument of ``err:tostring()``.

|
|
|
2012-09-05 09:45:45 -06:00
|
|
|
* ``dfhack.VERSION``
|
|
|
|
|
|
|
|
DFHack version string constant.
|
|
|
|
|
2012-09-05 07:37:36 -06:00
|
|
|
* ``dfhack.curry(func,args...)``, or ``curry(func,args...)``
|
|
|
|
|
|
|
|
Returns a closure that invokes the function with args combined
|
|
|
|
both from the curry call and the closure call itself. I.e.
|
|
|
|
``curry(func,a,b)(c,d)`` equals ``func(a,b,c,d)``.

Locking and finalization
|
|
|
|
------------------------
|
|
|
|
|
|
|
|
* ``dfhack.with_suspend(f[,args...])``
|
|
|
|
|
|
|
|
Calls ``f`` with arguments after grabbing the DF core suspend lock.
|
|
|
|
Suspending is necessary for accessing a consistent state of DF memory.
|
|
|
|
|
|
|
|
Returned values and errors are propagated through after releasing
|
|
|
|
the lock. It is safe to nest suspends.
|
|
|
|
|
|
|
|
Every thread is allowed only one suspend per DF frame, so it is best
|
|
|
|
to group operations together in one big critical section. A plugin
|
|
|
|
can choose to run all lua code inside a C++-side suspend lock.
|
|
|
|
|
|
|
|
* ``dfhack.call_with_finalizer(num_cleanup_args,always,cleanup_fn[,cleanup_args...],fn[,args...])``
|
|
|
|
|
|
|
|
Invokes ``fn`` with ``args``, and after it returns or throws an
|
|
|
|
error calls ``cleanup_fn`` with ``cleanup_args``. Any return values from
|
|
|
|
``fn`` are propagated, and errors are re-thrown.
|
|
|
|
|
|
|
|
The ``num_cleanup_args`` integer specifies the number of ``cleanup_args``,
|
|
|
|
and the ``always`` boolean specifies if cleanup should be called in any case,
|
|
|
|
or only in case of an error.
|
|
|
|
|
|
|
|
* ``dfhack.with_finalize(cleanup_fn,fn[,args...])``
|
|
|
|
|
|
|
|
Calls ``fn`` with arguments, then finalizes with ``cleanup_fn``.
|
|
|
|
Implemented using ``call_with_finalizer(0,true,...)``.
|
|
|
|
|
|
|
|
* ``dfhack.with_onerror(cleanup_fn,fn[,args...])``
|
|
|
|
|
|
|
|
Calls ``fn`` with arguments, then finalizes with ``cleanup_fn`` on any thrown error.
|
|
|
|
Implemented using ``call_with_finalizer(0,false,...)``.
|
|
|
|
|
|
|
|
* ``dfhack.with_temp_object(obj,fn[,args...])``
|
|
|
|
|
|
|
|
Calls ``fn(obj,args...)``, then finalizes with ``obj:delete()``.

Persistent configuration storage
|
2012-06-22 06:36:50 -06:00
|
|
|
--------------------------------
|
2012-04-03 03:13:44 -06:00
|
|
|
|
|
|
|
This api is intended for storing configuration options in the world itself.
|
|
|
|
It probably should be restricted to data that is world-dependent.
|
|
|
|
|
|
|
|
Entries are identified by a string ``key``, but it is also possible to manage
|
|
|
|
multiple entries with the same key; their identity is determined by ``entry_id``.
|
|
|
|
Every entry has a mutable string ``value``, and an array of 7 mutable ``ints``.
|
|
|
|
|
|
|
|
* ``dfhack.persistent.get(key)``, ``entry:get()``
|
|
|
|
|
|
|
|
Retrieves a persistent config record with the given string key,
|
|
|
|
or refreshes an already retrieved entry. If there are multiple
|
|
|
|
entries with the same key, it is undefined which one is retrieved
|
|
|
|
by the first version of the call.
|
|
|
|
|
|
|
|
Returns entry, or *nil* if not found.
|
|
|
|
|
|
|
|
* ``dfhack.persistent.delete(key)``, ``entry:delete()``
|
|
|
|
|
|
|
|
Removes an existing entry. Returns *true* if succeeded.
|
|
|
|
|
|
|
|
* ``dfhack.persistent.get_all(key[,match_prefix])``
|
|
|
|
|
|
|
|
Retrieves all entries with the same key, or starting with key..'/'.
|
|
|
|
Calling ``get_all('',true)`` will match all entries.
|
|
|
|
|
|
|
|
If none found, returns nil; otherwise returns an array of entries.
|
|
|
|
|
|
|
|
* ``dfhack.persistent.save({key=str1, ...}[,new])``, ``entry:save([new])``
|
|
|
|
|
|
|
|
Saves changes in an entry, or creates a new one. Passing true as
|
|
|
|
new forces creation of a new entry even if one already exists;
|
|
|
|
otherwise the existing one is simply updated.
|
|
|
|
Returns *entry, did_create_new*
|
|
|
|
|
|
|
|
Since the data is hidden in data structures owned by the DF world,
|
|
|
|
and automatically stored in the save game, these save and retrieval
|
|
|
|
functions can just copy values in memory without doing any actual I/O.
|
|
|
|
However, currently every entry has a 180+-byte dead-weight overhead.

|
--------------------
|
2012-04-06 09:56:19 -06:00
|
|
|
|
|
|
|
A material info record has fields:
|
|
|
|
|
|
|
|
* ``type``, ``index``, ``material``
|
|
|
|
|
|
|
|
DF material code pair, and a reference to the material object.
|
|
|
|
|
|
|
|
* ``mode``
|
|
|
|
|
|
|
|
One of ``'builtin'``, ``'inorganic'``, ``'plant'``, ``'creature'``.
|
|
|
|
|
|
|
|
* ``inorganic``, ``plant``, ``creature``
|
|
|
|
|
|
|
|
If the material is of the matching type, contains a reference to the raw object.
|
|
|
|
|
|
|
|
* ``figure``
|
|
|
|
|
|
|
|
For a specific creature material contains a ref to the historical figure.
|
|
|
|
|
|
|
|
Functions:
|
|
|
|
|
|
|
|
* ``dfhack.matinfo.decode(type,index)``
|
|
|
|
|
|
|
|
Looks up material info for the given number pair; if not found, returs *nil*.
|
|
|
|
|
|
|
|
* ``....decode(matinfo)``, ``....decode(item)``, ``....decode(obj)``
|
|
|
|
|
|
|
|
Uses ``matinfo.type``/``matinfo.index``, item getter vmethods,
|
|
|
|
or ``obj.mat_type``/``obj.mat_index`` to get the code pair.
|
|
|
|
|
|
|
|
* ``dfhack.matinfo.find(token[,token...])``
|
|
|
|
|
|
|
|
Looks up material by a token string, or a pre-split string token sequence.
|
|
|
|
|
|
|
|
* ``dfhack.matinfo.getToken(...)``, ``info:getToken()``
|
|
|
|
|
|
|
|
Applies ``decode`` and constructs a string token.
|
|
|
|
|
|
|
|
* ``info:toString([temperature[,named]])``
|
|
|
|
|
|
|
|
Returns the human-readable name at the given temperature.
|
|
|
|
|
|
|
|
* ``info:getCraftClass()``
|
|
|
|
|
|
|
|
Returns the classification used for craft skills.
|
|
|
|
|
|
|
|
* ``info:matches(obj)``
|
|
|
|
|
|
|
|
Checks if the material matches job_material_category or job_item.
|
|
|
|
Accept dfhack_material_category auto-assign table.

C++ function wrappers
|
|
|
|
=====================
|
|
|
|
|
|
|
|
Thin wrappers around C++ functions, similar to the ones for virtual methods.
|
2012-04-23 11:30:53 -06:00
|
|
|
One notable difference is that these explicit wrappers allow argument count
|
|
|
|
adjustment according to the usual lua rules, so trailing false/nil arguments
|
|
|
|
can be omitted.
|
2012-04-05 09:55:59 -06:00
|
|
|

this cache is only updated when the game is unpaused, and thus
|
|
|
|
can get out of date if doors are forbidden or unforbidden, or
|
|
|
|
tools like liquids or tiletypes are used. It also cannot possibly

take into account anything that depends on the actual units, like
|
|
|
|
burrows, or the presence of invaders.

|
|
|
|
|
* ``dfhack.buildings.countExtentTiles(extents,defval)``
|
|
|
|
|
|

Low-level building creation functions;
|
|

|
|
|
|
|

|
|
|
|
Configures an object returned by ``allocInstance``, using specified
|
|
|
|
parameters wherever appropriate. If the building has fixed size along

|
any dimension, the corresponding input parameter will be ignored.
|
2012-05-06 01:22:55 -06:00
|
|
|
Returns *false* if the building cannot be placed, or *true, width,
|
2012-05-01 08:55:30 -06:00
|
|
|
height, rect_area, true_area*. Returned width and height are the
|
|
|
|
final values used by the building; true_area is less than rect_area
|
|
|
|
if any tiles were removed from designation.
|
|
|
|
|
2012-05-06 09:09:11 -06:00
|
|
|
* ``dfhack.buildings.constructAbstract(building)``
|
|
|
|
|
|
|
|
Links a fully configured object created by ``allocInstance`` into the
|
|
|
|
world. The object must be an abstract building, i.e. a stockpile or civzone.
|
|
|
|
Returns *true*, or *false* if impossible.
|
|
|
|
|
2012-05-01 08:55:30 -06:00

|
|
|
|
|
|
|
|

|
|
|
|
world for construction, using a list of specific items as material.
|
|
|
|
Returns *true*, or *false* if impossible.
|
|
|
|
|
|
|
|
* ``dfhack.buildings.constructWithFilters(building, job_items)``
|
|
|
|
|
|
|
|

|
|
|
|
world for construction, using a list of job_item filters as inputs.
|
|
|
|
Returns *true*, or *false* if impossible. Filter objects are claimed
|
|
|
|
and possibly destroyed in any case.
|
|
|
|
Use a negative ``quantity`` field value to auto-compute the amount
|
|
|
|
from the size of the building.
|
|

|
|
|
|
|
2012-05-01 08:55:30 -06:00
|
|
|
More high-level functions are implemented in lua and can be loaded by
|
|
|
|
``require('dfhack.buildings')``. See ``hack/lua/dfhack/buildings.lua``.
|
|
|
|
|
2012-05-13 08:39:00 -06:00
|
|
|
Among them are:
|
|
|
|
|
|
|
|
* ``dfhack.buildings.getFiltersByType(argtable,type,subtype,custom)``
|
|
|
|
|
|
|
|
Returns a sequence of lua structures, describing input item filters
|
|
|
|
suitable for the specified building type, or *nil* if unknown or invalid.
|
|
|
|
The returned sequence is suitable for use as the ``job_items`` argument
|
|
|
|
of ``constructWithFilters``.
|
|
|
|
Uses tables defined in ``buildings.lua``.
|
|
|
|
|
|
|
|
Argtable members ``material`` (the default name), ``bucket``, ``barrel``,
|
|
|
|
``chain``, ``mechanism``, ``screw``, ``pipe``, ``anvil``, ``weapon`` are used to
|
|
|
|
augment the basic attributes with more detailed information if the
|
|
|
|
building has input items with the matching name (see the tables for naming details).
|
|
|
|
Note that it is impossible to *override* any properties this way, only supply those that
|
|
|
|
are not mentioned otherwise; one exception is that flags2.non_economic
|
|
|
|
is automatically cleared if an explicit material is specified.
|
|
|
|
|
|
|
|
* ``dfhack.buildings.constructBuilding{...}``
|
|
|
|
|
|
|
|
Creates a building in one call, using options contained
|
|
|
|
in the argument table. Returns the building, or *nil, error*.
|
|
|
|
|
|
|
|
**NOTE:** Despite the name, unless the building is abstract,
|
|
|
|
the function creates it in an 'unconstructed' stage, with
|
|
|
|
a queued in-game job that will actually construct it. I.e.
|
|
|
|
the function replicates programmatically what can be done
|
|
|
|
through the construct building menu in the game ui, except
|
|
|
|
that it does less environment constraint checking.
|
|
|
|
|
|
|
|
The following options can be used:
|
|
|
|
|
|
|
|
- ``pos = coordinates``, or ``x = ..., y = ..., z = ...``
|
|
|
|
|
|
|
|
Mandatory. Specifies the left upper corner of the building.
|
|
|
|
|
|
|
|
- ``type = df.building_type.FOO, subtype = ..., custom = ...``
|
|
|
|
|
|
|
|
Mandatory. Specifies the type of the building. Obviously, subtype
|
|
|
|
and custom are only expected if the type requires them.
|
|
|
|
|
|
|
|
- ``fields = { ... }``
|
|
|
|
|
|
|
|
Initializes fields of the building object after creation with ``df.assign``.
|
|
|
|
|
|
|
|
- ``width = ..., height = ..., direction = ...``
|
|
|
|
|
|
|
|
Sets size and orientation of the building. If it is
|
|
|
|
fixed-size, specified dimensions are ignored.
|
|
|
|
|
|
|
|
- ``full_rectangle = true``
|
|
|
|
|
|
|
|
For buildings like stockpiles or farm plots that can normally
|
|
|
|
accomodate individual tile exclusion, forces an error if any
|
|
|
|
tiles within the specified width*height are obstructed.
|
|
|
|
|
|
|
|
- ``items = { item, item ... }``, or ``filters = { {...}, {...}... }``
|
|
|
|
|
|
|
|
Specifies explicit items or item filters to use in construction.
|
|
|
|
It is the job of the user to ensure they are correct for the building type.
|
|
|
|
|
|
|
|
- ``abstract = true``
|
|
|
|
|
|
|
|
Specifies that the building is abstract and does not require construction.
|
|
|
|
Required for stockpiles and civzones; an error otherwise.
|
|
|
|
|
|
|
|
- ``material = {...}, mechanism = {...}, ...``
|
|
|
|
|
|
|
|
If none of ``items``, ``filter``, or ``abstract`` is used,
|
|
|
|
the function uses ``getFiltersByType`` to compute the input
|
|
|
|
item filters, and passes the argument table through. If no filters
|
|
|
|
can be determined this way, ``constructBuilding`` throws an error.

|
|
|
|
* ``dfhack.constructions.designateNew(pos,type,item_type,mat_index)``
|
|
|
|
|
|
|
|
Designates a new construction at given position. If there already is
|
|
|
|
a planned but not completed construction there, changes its type.
|
|
|
|
Returns *true*, or *false* if obstructed.
|
|
|
|
Note that designated constructions are technically buildings.
|
|
|
|
|
2012-05-06 09:09:11 -06:00
|
|
|
* ``dfhack.constructions.designateRemove(pos)``, or ``designateRemove(x,y,z)``
|
|
|
|
|
|
|
|
If there is a construction or a planned construction at the specified
|
|
|
|
coordinates, designates it for removal, or instantly cancels the planned one.
|
|
|
|
Returns *true, was_only_planned* if removed; or *false* if none found.

Screen API
|
|
|
|
----------
|
|
|
|
|
|
|
|
The screen module implements support for drawing to the tiled screen of the game.
|
|
|
|
Note that drawing only has any effect when done from callbacks, so it can only
|
|
|
|
be feasibly used in the core context.
|
|
|
|
|

Bright/bold text flag. If *nil*, computed based on (fg & 8); fg is masked to 3 bits.
|
2012-08-19 04:27:44 -06:00
|
|
|
Otherwise should be *true/false*.
|
|
|

2012-08-19 10:00:10 -06:00
|
|
|
Graphical tile id. Ignored unless [GRAPHICS:YES] was in init.txt.

|
|
|
``tile_color = true``
|
|
|
|
Specifies that the tile should be shaded with *fg/bg*.
|
|
|
|

|
|
|
|
If specified, overrides *tile_color* and supplies shading colors directly.
|
|
|
|
|
|
|
|
Returns *false* if coordinates out of bounds, or other error.
|
|
|
|

* ``dfhack.screen.paintString(pen,x,y,text)``
|
|
|
|
|
|
|

|
|
|
|
2012-08-19 04:27:44 -06:00
|
|
|
* ``dfhack.screen.clear()``
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
* ``dfhack.screen.invalidate()``
|
|
|
|
|
|
|
|
Requests repaint of the screen by setting a flag. Unlike other
|
|
|
|
functions in this section, this may be used at any time.
|
|
|
|
|
|
|
|
In order to actually be able to paint to the screen, it is necessary
|
|
|
|
to create and register a viewscreen (basically a modal dialog) with
|
2012-08-22 02:28:01 -06:00
|
|
|
the game.
|
|
|
|
|
|
|
|
**NOTE**: As a matter of policy, in order to avoid user confusion, all
|
|
|
|
interface screens added by dfhack should bear the "DFHack" signature.
|
|
|
|
|
|
|
|
Screens are managed with the following functions:
|
2012-08-19 04:27:44 -06:00
|
|
|
|
|
|
|
* ``dfhack.screen.show(screen[,below])``
|
|
|
|
|
|
|
|
Displays the given screen, possibly placing it below a different one.
|
|
|
|
The screen must not be already shown. Returns *true* if success.
|
|
|
|
|
2012-08-24 03:20:08 -06:00
|
|
|
* ``dfhack.screen.dismiss(screen[,to_first])``
|
2012-08-19 04:27:44 -06:00
|
|
|
|
|
|
|
Marks the screen to be removed when the game enters its event loop.
|
2012-08-24 03:20:08 -06:00
|
|
|
If ``to_first`` is *true*, all screens up to the first one will be deleted.
|
2012-08-19 04:27:44 -06:00
|
|
|
|
|
|
|
* ``dfhack.screen.isDismissed(screen)``
|
|
|
|
|
|
|
|
Checks if the screen is already marked for removal.
|
|
|
|
|
|
|
|
Apart from a native viewscreen object, these functions accept a table
|
|
|
|
as a screen. In this case, ``show`` creates a new native viewscreen
|
|
|
|
that delegates all processing to methods stored in that table.
|
|
|
|
|
|
|
|
**NOTE**: Lua-implemented screens are only supported in the core context.
|
|
|
|
|
|
|
|
Supported callbacks and fields are:
|
|
|
|
|
|
|
|
* ``screen._native``
|
|
|
|
|
|
|
|
Initialized by ``show`` with a reference to the backing viewscreen
|
|
|
|
object, and removed again when the object is deleted.
|
|
|
|
|
2012-08-24 03:20:08 -06:00
|
|
|
* ``function screen:onShow()``
|
|
|
|
|
|
|
|
Called by ``dfhack.screen.show`` if successful.
|
|
|
|
|
|
|
|
* ``function screen:onDismiss()``
|
|
|
|
|
|
|
|
Called by ``dfhack.screen.dismiss`` if successful.
|
|
|
|
|
2012-08-19 04:27:44 -06:00
|
|
|
* ``function screen:onDestroy()``
|
|
|
|
|
|
|
|
Called from the destructor when the viewscreen is deleted.
|
|
|
|
|
2012-08-24 03:20:08 -06:00
|
|
|
* ``function screen:onResize(w, h)``
|
|
|
|
|
|
|
|
Called before ``onRender`` or ``onIdle`` when the window size has changed.
|
|
|
|
|
2012-08-19 04:27:44 -06:00
|
|
|
* ``function screen:onRender()``
|
|
|
|
|
|
|
|
Called when the viewscreen should paint itself. This is the only context
|
|
|
|
where the above painting functions work correctly.
|
|
|
|
|
|
|
|
If omitted, the screen is cleared; otherwise it should do that itself.
|
|
|
|
In order to make a see-through dialog, call ``self._native.parent:render()``.
|
|
|
|
|
|
|
|
* ``function screen:onIdle()``
|
|
|
|
|
|
|
|
Called every frame when the screen is on top of the stack.
|
|
|
|
|
|
|
|
* ``function screen:onHelp()``
|
|
|
|
|
|
|
|
Called when the help keybinding is activated (usually '?').
|
|
|
|
|
|
|
|
* ``function screen:onInput(keys)``
|
|
|
|
|
|
|
|
Called when keyboard or mouse events are available.
|
|
|
|
If any keys are pressed, the keys argument is a table mapping them to *true*.
|
|
|
|
Note that this refers to logical keybingings computed from real keys via
|
|
|
|
options; if multiple interpretations exist, the table will contain multiple keys.
|
|
|
|
|
2012-08-19 10:00:10 -06:00
|
|
|
The table also may contain special keys:
|
|
|
|
|
|
|
|
``_STRING``
|
|
|
|
Maps to an integer in range 0-255. Duplicates a separate "STRING_A???" code for convenience.
|
|
|
|
|
|
|
|
``_MOUSE_L, _MOUSE_R``
|
|
|
|
If the left or right mouse button is pressed.
|
|
|
|
|
2012-08-19 04:27:44 -06:00
|
|
|
If this method is omitted, the screen is dismissed on receival of the ``LEAVESCREEN`` key.

Core interpreter context
|
|
|
|
========================
|
|
|
|
|
|
|
|
While plugins can create any number of interpreter instances,
|
|
|
|
there is one special context managed by dfhack core. It is the
|
|
|
|
only context that can receive events from DF and plugins.
|
|
|
|
|
|
|
|
Core context specific functions:
|
|
|
|
|
|
|
|
* ``dfhack.is_core_context``
|
|
|
|
|
|
|
|
Boolean value; *true* in the core context.
|
2012-04-17 01:45:09 -06:00
|
|
|
|
2012-05-04 10:59:06 -06:00
|
|
|
* ``dfhack.timeout(time,mode,callback)``
|
|
|
|
|
|
|
|
Arranges for the callback to be called once the specified
|
|
|
|
period of time passes. The ``mode`` argument specifies the
|
|
|
|
unit of time used, and may be one of ``'frames'`` (raw FPS),
|
|
|
|
``'ticks'`` (unpaused FPS), ``'days'``, ``'months'``,
|
|
|
|
``'years'`` (in-game time). All timers other than
|
|
|
|
``'frames'`` are cancelled when the world is unloaded,
|
|
|
|
and cannot be queued until it is loaded again.
|
|
|
|
Returns the timer id, or *nil* if unsuccessful due to
|
|
|
|
world being unloaded.
|
|
|
|
|
2012-05-16 07:06:08 -06:00
|
|
|
* ``dfhack.timeout_active(id[,new_callback])``
|
|
|
|
|
|
|
|
Returns the active callback with the given id, or *nil*
|
|
|
|
if inactive or nil id. If called with 2 arguments, replaces
|
|
|
|
the current callback with the given value, if still active.
|
|
|
|
Using ``timeout_active(id,nil)`` cancels the timer.
|
|
|
|
|
2012-04-17 01:45:09 -06:00
|
|
|
* ``dfhack.onStateChange.foo = function(code)``
|
|
|
|
|
|
|
|
Event. Receives the same codes as plugin_onstatechange in C++.

An event is a native object transparently wrapping a lua table,
|
|
|
|
and implementing a __call metamethod. When it is invoked, it loops
|
2012-04-17 01:45:09 -06:00
|
|
|
through the table with next and calls all contained values.
|
|
|
|
This is intended as an extensible way to add listeners.
|
|
|
|
|
|
|
|
This type itself is available in any context, but only the
|
|
|
|
core context has the actual events defined by C++ code.
|
|
|
|
|
|
|
|
Features:
|
|
|
|
|
|
|
|
* ``dfhack.event.new()``
|
|
|
|
|
|
|
|
Creates a new instance of an event.
|
|
|
|
|
|
|
|
* ``event[key] = function``
|
|
|
|
|
2012-08-23 09:27:12 -06:00
|
|
|
Sets the function as one of the listeners. Assign *nil* to remove it.
|
2012-04-17 01:45:09 -06:00
|
|
|
|
|
|
|
**NOTE**: The ``df.NULL`` key is reserved for the use by
|
2012-08-23 09:27:12 -06:00
|
|
|
the C++ owner of the event; it is an error to try setting it.
|
|
|
|
|
|
|
|
* ``#event``
|
|
|
|
|
|
|
|
Returns the number of non-nil listeners.
|
|
|
|
|
|
|
|
* ``pairs(event)``
|
|
|
|
|
|
|
|
Iterates over all listeners in the table.
|
2012-04-17 01:45:09 -06:00
|
|
|
|
|
|
|
* ``event(args...)``
|
|
|
|
|
|
|
|
Invokes all listeners contained in the event in an arbitrary
|
|
|
|
order using ``dfhack.safecall``.

DFHack sets up the lua interpreter so that the built-in ``require``
|
|
|
|
function can be used to load shared lua code from hack/lua/.
|
|
|
|
The ``dfhack`` namespace reference itself may be obtained via
|
|
|
|
``require('dfhack')``, although it is initially created as a
|
|
|
|
global by C++ bootstrap code.
|
|
|
|
|
2012-06-24 02:51:19 -06:00
|
|
|
The following module management functions are provided:
|
2012-06-22 10:17:55 -06:00
|
|
|
|
|
|
|
* ``mkmodule(name)``
|
|
|
|
|
|
|
|
Creates an environment table for the module. Intended to be used as::
|
|
|
|
|
|
|
|
local _ENV = mkmodule('foo')
|
|
|
|
...
|
|
|
|
return _ENV
|
|
|
|
|
|
|
|
If called the second time, returns the same table; thus providing reload support.
|
|
|
|
|
|
|
|
* ``reload(name)``
|
|
|
|
|
|
|
|
Reloads a previously ``require``-d module *"name"* from the file.
|
|
|
|
Intended as a help for module development.
|
|
|
|
|
|
|
|
* ``dfhack.BASE_G``
|
|
|
|
|
|
|
|
This variable contains the root global environment table, which is
|
|
|
|
used as a base for all module and script environments. Its contents
|
|
|
|
should be kept limited to the standard Lua library and API described
|
|
|
|
in this document.

|
|
|
|
|
|
|
* ``dfhack.onStateChange`` event codes
|
|
|
|
|
|
|
|
Available only in the core context, as is the event itself:
|
|
|
|
|
|
|
|
SC_WORLD_LOADED, SC_WORLD_UNLOADED, SC_MAP_LOADED,

If the argument is a lua table or DF object reference, prints all fields.
|
|
|
|
|
|
|
|
* ``copyall(obj)``
|
|
|
|
|
|
|
|
Returns a shallow copy of the table or reference as a lua table.
|
|
|
|
|
|
|
|
* ``pos2xyz(obj)``
|
|
|
|
|
|
|
|
The object must have fields x, y and z. Returns them as 3 values.
|
|
|
|
If obj is *nil*, or x is -30000 (the usual marker for undefined
|
|
|
|
coordinates), returns *nil*.
|
|
|
|
|
|
|
|
* ``xyz2pos(x,y,z)``
|
|
|
|
|
|
|
|
Returns a table with x, y and z as fields.
|
|
|
|
|
|
|
|
* ``safe_index(obj,index...)``
|
|
|
|
|
|
|
|
Walks a sequence of dereferences, which may be represented by numbers or strings.
|
|
|
|
Returns *nil* if any of obj or indices is *nil*, or a numeric index is out of array bounds.

|
=====
|
|
|
|
|
|
|
|
* ``utils.compare(a,b)``
|
|
|
|
|
|
|
|
Comparator function; returns *-1* if a<b, *1* if a>b, *0* otherwise.
|
|
|
|
|
|
|
|
* ``utils.compare_name(a,b)``
|
|
|
|
|
|
|
|
Comparator for names; compares empty string last.
|
|
|
|
|
|
|
|
* ``utils.is_container(obj)``
|
|
|
|
|
|
|
|
Checks if obj is a container ref.
|
|
|
|
|
|
|
|
* ``utils.make_index_sequence(start,end)``
|
|
|
|
|
|
|
|
Returns a lua sequence of numbers in start..end.
|
|
|
|
|
|
|
|
* ``utils.make_sort_order(data, ordering)``
|
|
|
|
|
2012-06-30 06:25:41 -06:00
|
|
|
Computes a sorted permutation of objects in data, as a table of integer
|
2012-06-24 02:51:19 -06:00
|
|
|
indices into the data sequence. Uses ``data.n`` as input length
|
|
|
|
if present.
|
|
|
|
|
|
|
|
The ordering argument is a sequence of ordering specs, represented
|
|
|
|
as lua tables with following possible fields:
|
|
|
|
|
|
|
|
ord.key = *function(value)*
|
2012-06-30 06:25:41 -06:00
|
|
|
Computes comparison key from input data value. Not called on nil.
|
2012-06-24 02:51:19 -06:00
|
|
|
If omitted, the comparison key is the value itself.
|
|
|
|
ord.key_table = *function(data)*
|
|
|
|
Computes a key table from the data table in one go.
|
|
|
|
ord.compare = *function(a,b)*
|
|
|
|
Comparison function. Defaults to ``utils.compare`` above.
|
|
|
|
Called on non-nil keys; nil sorts last.
|
|
|
|
ord.nil_first = *true/false*
|
|
|
|
If true, nil keys are sorted first instead of last.
|
|
|
|
ord.reverse = *true/false*
|
|
|
|
If true, sort non-nil keys in descending order.
|
|
|
|
|
2012-06-30 06:25:41 -06:00
|
|
|
For every comparison during sorting the specs are applied in
|
|
|
|
order until an unambiguous decision is reached. Sorting is stable.
|
|
|
|
|
|
|
|
Example of sorting a sequence by field foo::
|
|
|
|
|
|
|
|
local spec = { key = function(v) return v.foo end }
|
|
|
|
local order = utils.make_sort_order(data, { spec })
|
|
|
|
local output = {}
|
|
|
|
for i = 1,#order do output[i] = data[order[i]] end
|
|
|
|
|
|
|
|
Separating the actual reordering of the sequence in this
|
|
|
|
way enables applying the same permutation to multiple arrays.
|
2012-06-24 02:51:19 -06:00
|
|
|
This function is used by the sort plugin.
|
|
|
|
|
|
|
|
* ``utils.assign(tgt, src)``
|
|
|
|
|
|
|
|
Does a recursive assignment of src into tgt.
|
|
|
|
Uses ``df.assign`` if tgt is a native object ref; otherwise
|
|
|
|
recurses into lua tables.
|
|
|
|
|
|
|
|
* ``utils.clone(obj, deep)``
|
|
|
|
|
|
|
|
Performs a shallow, or semi-deep copy of the object as a lua table tree.
|
|
|
|
The deep mode recurses into lua tables and subobjects, except pointers
|
|
|
|
to other heap objects.
|
|
|
|
Null pointers are represented as df.NULL. Zero-based native containers
|
|
|
|
are converted to 1-based lua sequences.
|
|
|
|
|
|
|
|
* ``utils.clone_with_default(obj, default, force)``
|
|
|
|
|
|
|
|
Copies the object, using the ``default`` lua table tree
|
|
|
|
as a guide to which values should be skipped as uninteresting.
|
|
|
|
The ``force`` argument makes it always return a non-*nil* value.
|
|
|
|
|
|
|
|
* ``utils.sort_vector(vector,field,cmpfun)``
|
|
|
|
|
|
|
|
Sorts a native vector or lua sequence using the comparator function.
|
|
|
|
If ``field`` is not *nil*, applies the comparator to the field instead
|
|
|
|
of the whole object.
|
|
|
|
|
|
|
|
* ``utils.binsearch(vector,key,field,cmpfun,min,max)``
|
|
|
|
|
|
|
|
Does a binary search in a native vector or lua sequence for
|
|
|
|
``key``, using ``cmpfun`` and ``field`` like sort_vector.
|
|
|
|
If ``min`` and ``max`` are specified, they are used as the
|
|
|
|
search subrange bounds.
|
|
|
|
|
|
|
|
If found, returns *item, true, idx*. Otherwise returns
|
|
|
|
*nil, false, insert_idx*, where *insert_idx* is the correct
|
|
|
|
insertion point.
|
|
|
|
|
|
|
|
* ``utils.insert_sorted(vector,item,field,cmpfun)``
|
|
|
|
|
|
|
|
Does a binary search, and inserts item if not found.
|
|
|
|
Returns *did_insert, vector[idx], idx*.
|
|
|
|
|
|
|
|
* ``utils.insert_or_update(vector,item,field,cmpfun)``
|
|
|
|
|
|
|
|
Like ``insert_sorted``, but also assigns the item into
|
|
|
|
the vector cell if insertion didn't happen.
|
|
|
|
|
|
|
|
As an example, you can use this to set skill values::
|
|
|
|
|
|
|
|
utils.insert_or_update(soul.skills, {new=true, id=..., rating=...}, 'id')
|
|
|
|
|
|
|
|
(For an explanation of ``new=true``, see table assignment in the wrapper section)
|
|
|
|
|
|
|
|
* ``utils.prompt_yes_no(prompt, default)``
|
|
|
|
|
|
|
|
Presents a yes/no prompt to the user. If ``default`` is not *nil*,
|
|
|
|
allows just pressing Enter to submit the default choice.
|
|
|
|
If the user enters ``'abort'``, throws an error.
|
|
|
|
|
|
|
|
* ``utils.prompt_input(prompt, checkfun, quit_str)``
|
|
|
|
|
|
|
|
Presents a prompt to input data, until a valid string is entered.
|
|
|
|
Once ``checkfun(input)`` returns *true, ...*, passes the values
|
|
|
|
through. If the user enters the quit_str (defaults to ``'~~~'``),
|
|
|
|
throws an error.
|
|
|
|
|
|
|
|
* ``utils.check_number(text)``
|
|
|
|
|
|
|
|
A ``prompt_input`` ``checkfun`` that verifies a number input.

|
|
======
|
|
|
|
|
|
|
|
A third-party lua table dumper module from
|
|
|
|
http://lua-users.org/wiki/DataDumper. Defines one
|
|
|
|
function:
|
|
|
|
|
|
|
|
* ``dumper.DataDumper(value, varname, fastmode, ident, indent_step)``
|
|
|
|
|
|
|
|
Returns ``value`` converted to a string. The ``indent_step``
|
|
|
|
argument specifies the indentation step size in spaces. For
|
|
|
|
the other arguments see the original documentation link above.

Plugins
|
|
|
|
=======
|
|
|
|
|
|
|
|
DFHack plugins may export native functions and events
|
|
|
|
to lua contexts. They are automatically imported by
|
|
|
|
``mkmodule('plugins.<name>')``; this means that a lua
|
|
|
|
module file is still necessary for ``require`` to read.
|
|
|
|
|
|
|
|
The following plugins have lua support.
|
|
|
|
|
|
|
|
burrows
|
|
|
|
=======
|
|
|
|
|
|
|
|
Implements extended burrow manipulations.
|
|
|
|
|
|
|
|
Events:
|
|
|
|
|
|
|
|
* ``onBurrowRename.foo = function(burrow)``
|
|
|
|
|
|
|
|
Emitted when a burrow might have been renamed either through
|
|
|
|
the game UI, or ``renameBurrow()``.
|
|
|
|
|
2012-05-12 10:54:26 -06:00
|
|
|
* ``onDigComplete.foo = function(job_type,pos,old_tiletype,new_tiletype,worker)``
|
2012-04-23 11:30:53 -06:00
|
|
|
|
|
|
|
Emitted when a tile might have been dug out. Only tracked if the
|
|
|
|
auto-growing burrows feature is enabled.
|
|
|
|
|
|
|
|
Native functions:
|
|
|
|
|
|
|
|
* ``renameBurrow(burrow,name)``
|
|
|
|
|
|
|
|
Renames the burrow, emitting ``onBurrowRename`` and updating auto-grow state properly.
|
|
|
|
|
|
|
|
* ``findByName(burrow,name)``
|
|
|
|
|
|
|
|
Finds a burrow by name, using the same rules as the plugin command line interface.
|
|
|
|
Namely, trailing ``'+'`` characters marking auto-grow burrows are ignored.
|
|
|
|
|
|
|
|
* ``copyUnits(target,source,enable)``
|
|
|
|
|
|
|
|
Applies units from ``source`` burrow to ``target``. The ``enable``
|
|
|
|
parameter specifies if they are to be added or removed.
|
|
|
|
|
|
|
|
* ``copyTiles(target,source,enable)``
|
|
|
|
|
|
|
|
Applies tiles from ``source`` burrow to ``target``. The ``enable``
|
|
|
|
parameter specifies if they are to be added or removed.
|
|
|
|
|
|
|
|
* ``setTilesByKeyword(target,keyword,enable)``
|
|
|
|
|
|
|
|
Adds or removes tiles matching a predefined keyword. The keyword
|
|
|
|
set is the same as used by the command line.
|
|
|
|
|
2012-04-26 02:56:28 -06:00
|
|
|
The lua module file also re-exports functions from ``dfhack.burrows``.

|
|
====
|
|
|
|
|
|
|
|
Does not export any native functions as of now. Instead, it
|
|
|
|
calls lua code to perform the actual ordering of list items.

Scripts
|
|
|
|
=======
|
|
|
|
|
|
|
|
Any files with the .lua extension placed into hack/scripts/*
|
|
|
|
are automatically used by the DFHack core as commands. The
|
|
|
|
matching command name consists of the name of the file sans
|
|
|
|
the extension.
|
|
|
|
|
2012-06-24 02:51:19 -06:00
|
|
|
If the first line of the script is a one-line comment, it is
|
|
|
|
used by the built-in ``ls`` and ``help`` commands.
|
|
|
|
|
2012-06-22 10:17:55 -06:00
|
|
|
**NOTE:** Scripts placed in subdirectories still can be accessed, but
|
|
|
|
do not clutter the ``ls`` command list; thus it is preferred
|
|
|
|
for obscure developer-oriented scripts and scripts used by tools.
|
|
|
|
When calling such scripts, always use '/' as the separator for
|
|
|
|
directories, e.g. ``devel/lua-example``.
|
|
|
|
|
|
|
|
Scripts are re-read from disk every time they are used
|
|
|
|
(this may be changed later to check the file change time); however
|
|
|
|
the global variable values persist in memory between calls.
|
|
|
|
Every script gets its own separate environment for global
|
|
|
|
variables.
|
|
|
|
|
|
|
|
Arguments are passed in to the scripts via the **...** built-in
|
|
|
|
quasi-variable; when the script is called by the DFHack core,
|
|
|
|
they are all guaranteed to be non-nil strings.
|
|
|
|
|
|
|
|
DFHack core invokes the scripts in the *core context* (see above);
|
|
|
|
however it is possible to call them from any lua code (including
|
|
|
|
from other scripts) in any context, via the same function the core uses:
|
|
|
|
|
|
|
|
* ``dfhack.run_script(name[,args...])``
|
|
|
|
|
|
|
|
Run a lua script in hack/scripts/, as if it was started from dfhack command-line.
|
|
|
|
The ``name`` argument should be the name stem, as would be used on the command line.
|
|
|
|
|
|
|
|
Note that this function lets errors propagate to the caller.
|
