# Set up something to print out s-expressions.
define pr
set Fprin1 ($, Qexternal_debugging_output)
echo \n
end
document pr
Print the emacs s-expression which is $.
Works only when an inferior emacs is executing.

# machine-description files.
set $data_seg_bits = 0
define mips
set $data_seg_bits = 0x10000000
end
document mips
Set up the xfoo macros to deal with the MIPS processor.
Specifically, this sets $data_seg_bits to the right thing.
end

output (enum Lisp_Type) (($ >> 24) & 0x7f)
echo \n
end
document xtype
Print the type of $, assuming it is an Elisp value.
end
define xint
print (($ & 0x00ffffff) << 8) >> 8
end
document xint
Print $, assuming it is an Elisp integer. This gets the sign right.
end

Print $ as a window pointer, assuming it is an Elisp window value.
Print the window's position as "WIDTHxHEIGHT+LEFT+TOP".
end

end
document xbuffer
Set $ as a buffer pointer, assuming it is an Elisp buffer value.
Print the name of the buffer.
end
define xsymbol
print (struct Lisp_Symbol *) (($ & 0x00ffffff) | $data_seg_bits)
output &$->name->data
echo \n
end

Print the name and address of the symbol $.
This command assumes that $ is an Elisp symbol value.
end

output ($->size > 10000) ? "big string" : ($->data[0])@($->size)

end
document xstring
Print the contents and address of the string $.
This command assumes that $ is an Elisp string value.
end
