Bitfields behave like special fixed-size containers.

The ``_enum`` property points to the bitfield type.
Numerical indices correspond to the shift value,
and if a subfield occupies multiple bits, the
``ipairs`` order would have a gap.
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}``.

Equivalent to the method, but also allows a reference as proxy for its type.
* ``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.

Internal API
------------
These functions are intended for the use by dfhack developers,
and are only documented here for completeness:
* ``dfhack.internal.scripts``
The table used by ``dfhack.run_script()`` to give every script its own
global environment, persistent between calls to the script.
* ``dfhack.internal.getAddress(name)``
Returns the global address ``name``, or *nil*.
* ``dfhack.internal.setAddress(name, value)``
Sets the global address ``name``. Returns the value of ``getAddress`` before the change.
* ``dfhack.internal.getVTable(name)``
Returns the pre-extracted vtable address ``name``, or *nil*.
* ``dfhack.internal.getBase()``
Returns the base address of the process.
* ``dfhack.internal.getMemRanges()``
Returns a sequence of tables describing virtual memory ranges of the process.
* ``dfhack.internal.memmove(dest,src,count)``
Wraps the standard memmove function. Accepts both numbers and refs as pointers.
* ``dfhack.internal.memcmp(ptr1,ptr2,count)``
Wraps the standard memcmp function.
* ``dfhack.internal.memscan(haystack,count,step,needle,nsize)``
Searches for ``needle`` of ``nsize`` bytes in ``haystack``,
using ``count`` steps of ``step`` bytes.
Returns: *step_idx, sum_idx, found_ptr*, or *nil* if not found.
* ``dfhack.internal.diffscan(old_data, new_data, start_idx, end_idx, eltsize[, oldval, newval, delta])``
Searches for differences between buffers at ptr1 and ptr2, as integers of size eltsize.
The oldval, newval or delta arguments may be used to specify additional constraints.
Returns: *found_index*, or *nil* if end reached.

You can use single-quotes for strings ; avoid double-quotes that are parsed
and removed by the dfhack console.
If dfhack reports 'rb_eval is not a recognized command', check stderr.log. You
need a valid 32-bit ruby library to work, and ruby1.8 is prefered (ruby1.9 may
crash DF on startup for now). Install the library in the df root folder (or
hack/ on linux), the library should be named 'libruby.dll' (.so on linux).
You can download a tested version at http://github.com/jjyg/dfhack/downloads/
The plugin also interfaces with dfhack 'onupdate' hook.
To register ruby code to be run every graphic frame, use:
handle = df.onupdate_register { puts 'i love flood' }
handle = df.onupdate_register { puts 'i love flooding the console' }
To stop being called, use:
df.onupdate_unregister handle
The same mechanism is available for onstatechange.

Compilation
-----------
The plugin consists of the ruby.rb file including user comfort functions ;
ruby-memstruct.rb describing basic classes used by the autogenerated code, and
embedded at the beginnig of ruby-autogen.rb, and the generated code.
The plugin consists of the ruby.rb file including user comfort functions and
describing basic classes used by the autogenerated code, and ruby-autogen.rb,
the auto-generated code.
The generated code is generated by codegen.pl, which takes the codegen.out.xml
file as input.
One of the limitations of the xml file is that it does not include structure
offsets, as they depend on the compiler. To overcome that, codegen runs in two
passes. The first pass generates a ruby-autogen.cpp file, that will output the
structure offsets ; the second pass will generate the ruby-autogen.rb using the
output of the compiled ruby-autogen.cpp.
For exemple, from
For exemple,
<ld:global-type ld:meta="struct-type" type-name="unit">
<ld:field type-name="language_name" name="name" ld:meta="global"/>
<ld:field name="custom_profession" ld:meta="primitive" ld:subtype="stl-string"/>
<ld:field ld:subtype="enum" base-type="int16_t" name="profession" type-name="profession" ld:meta="global"/>
We generate the cpp
printf("%s = %d", "offsetof(df::unit, language_name)", offsetof(df::unit, language_name));
printf("%s = %d", "offsetof(df::unit, custom_profession)", offsetof(df::unit, custom_profession));
printf("%s = %d", "offsetof(df::unit, profession)", offsetof(df::unit, profession));
Which generates (on linux)
offsetof(df::unit, name) = 0
offsetof(df::unit, custom_profession) = 60
offsetof(df::unit, profession) = 64
Which generates
Will generate
class Unit < MemHack::Compound
field(:name, 0) { global :LanguageName }
field(:custom_profession, 60) { stl_string }
field(:profession, 64) { number 16, true }
The field method has 2 arguments: the name of the method and the member offset ;
the block specifies the member type. See ruby-memstruct.rb for more information.
The syntax for the 'field' method is:
1st argument = name of the method
2nd argument = offset of this field from the beginning of the struct.
The block argument describes the type of the field: uint32, ptr to global...
Primitive type access is done through native methods in ruby.cpp (vector length,
raw memory access, etc)
