+% General description: 
+% The macros in this package model the construction of syntactic
+% tree structures as a genuinely graphical problem: they contain two types of
+% objects, BRANCHES and NODE LABELS, and these are positioned relative to a
+% GRID. It is essential that each of these three elements is constructed
+% independent of the other two, and hence they can be modified without
+% unwanted side effects. This is, to my mind, the most important difference to
+% other tree drawing macro packages, where, in particular, the label width often
+% changes the angles of the branches. A second important advantage lies
+% in the xypic package. xypic generates Metafont code, so the drawing of trees is
+% not dependent on postscript specials, as, e.g., in ps-trees. Hence, no
+% postprocessing is required. The trees generated by postscript specials can
+% neither be seen in a dvi previewer (at least not in my current version of
+% xdvi for linux), nor can they be taken over into a pdf file by pdflatex
+% (but it works in dvi to pdf conversion with dvipdf, or ps to pdf conversion
+% with ps2pdf). 
+%%
+
+%% Earlier xyling users:
+% I tried to systematise the definitions of node labels and branches. The easy
+% commands are now defined in terms of the kontrolled commands, i.e., \K is
+% defined via \Kk etc. I also defined a general branching command, \Bkk in its
+% most kontrolled version. It underlies all the branching commands. I redefined
+% all old commands in terms of the new ones. You should not see a difference,
+% however. The commands should be fully backwards compatible. Commands that have
+% been renamed are included via simple \let instructions. Please check the list
+% at the end of this file. If there is anything going wrong for you, or you miss
+% a command that has been there earlier, please let me know. 
+
+% load xyling -
+% put the following into the preamble:
+%
+% \usepackage{xyling}
+
+% here we start. First of all, we load the xy package, with all options
+% (although most options might not be necessary), including use of colours: 
+
+\RequirePackage[color,all,dvips]{xy}
+\UseCrayolaColors
+
+% IMPORTANT NOTE: 
+% The use of the dvips option might cause branches to disappear when you
+% preoduce a pdf file with pdflatex. If this is so, there are two ways of
+% overcoming this:
+%
+% 1. erase the dvips option above, i.e., use instead:
+% \RequirePackage[color,all]{xy}
+% You will no longer be able to use coloured branches now, however.
+%
+% 2. create the pdf file via dvips and ps2pdf conversion. This is how the
+% documentation pdf file is created.
+
+
+% A tree is a simple macro of the form "\Tree{ ... }"
+% It is an xymatrix, with "&" as column separator and "\\" as row separator,
+% just like tabular:
+
+\makeatother
+\newcommand{\Tree}[2][0]{\raisebox{1ex}{\xymatrix @H=.3pc @W=2pc @R=2pc @C=#1pc {#2}}}
+\newcommand{\Treek}[3][0]{\raisebox{1ex}{\xymatrix  @H=.3pc @W=2pc @R=#2pc @C=#1pc {#3}}}
+
+% \Tree has an optional argument that can be used for changing the space between
+% columns. The default is 0. A negative value makes the tree smaller,
+% a positive value makes it wider. 
+
+% Space between rows is set to a default of 2pc (defined in "@R=2pc"). \Treek
+% gives you "k"ontrol over the distance between rows. \Treek{2}{} =
+% \Tree{}. Values higher than 2 raise the row distance, smaller ones shrink it. 
+
+% You can use \Tree and \Treek for objects other than syntactic trees, of
+% course. Be it phonological structures or simply any other graphical object
+% that mixes words and lines in a graphical way. 
+
+% @R=2pc is fine for one-row node labels, it might be too small for
+% multi-row labels. LFG has trees with two-row labels. To include these, you
+% will have to enlarge @R, define two-line labels, and branches originating from
+% two-line labels. See below for an example.
+
+% Node labels have the width of 2pc, as determined by the @W variable. This is
+% nearly the width of two upright letters, like NP, VP etc. Extremely wide
+% labels do not affect the matrix, because the node width is determined
+% independent of the content of the node. If you need something different,
+% change the @W value here.
+
+% For the placement of node labels, we use the commands, \Kk, and \K. \Kk
+% offers you full control over the horizontal and vertical placement of the
+% label. 
+
+\newcommand{\Kk}[3][0]{%
+  \POS[]+(#1,-1.5)+(0,#2) \save*\txt{\textnormal{\rule[-6pt]{0pt}{18pt}#3}}
+  \restore}
+
+\newcommand{\K}[2][0]{%
+  \Kk[#1]{0}{#2}}
+
+% A node should usually be introduced with the command \K{...}. The optional argument
+% is the horizontal adjustment in pc. Positive values move the label to the
+% right, negative values to the left.
+% Text is centered, both horizontally and vertically! 
+% 1pc is about .5em in a 12pt font.
+
+% I inserted a strut (i.e., \rule[-6pt]{0pt}) to make indexed labels behave like
+% non-indexed ones. It works for up to 12pt fonts. Might have to be adjusted for
+% other font sizes. 
+% The node is inserted at  the center of the box, the center with respect to
+% both the horizontal and the vertical dimension! Boxes with indices, like
+% NP$_{i}$, are higher than an ordinary NP box. As a consequence of this, the
+% NP of an indexed box would appear slightly higher than a sister node label
+% without the strut. 
+
+% \Kk offers full `k'ontrol over the vertical and horizontal dimension. The
+% optional argument of \Kk is the same as that of \K, but there is an additional
+% obligatory argument denoting the vertical adjustment. So the syntax is:
+% \Kk[horizontal adjustment]{vertical adjustment}{node label}
+% The command \Kk[1]{1}{VP} places the node VP 1pc right of and 1pc higher than
+% the standard position. This in fact allows  you to put anything anywhere in
+% the tree. You can add comments to the side of the tree etc. 
+
+% Branch commands are inserted immediately after their dominating node. They are
+% defined with respect to their target position in the matrix. We again start
+% with the controlled version:
+
+\newcommand{\Bkk}[3]{\POS[]-(0,4)+(#1)\ar@{-}[#3]+(0,2)+(#2)}
+
+% The three arguments are: 1=adjustment of starting position, 2=adjustment of
+% target position, 3=target location. The first two arguments are value pairs
+% for the x- and y-axis: (horizontal,vertical).
+
+% The third argument describes the target location of the branch, a string
+% containing some of the following letters: d
+% for one step down, l for one step left, r for one step right, u for one step
+% up - but don't use u, because it will result in striking out the label name
+% ... :-) branches always go downwards.  dr = 1 down, 1 right, drr = 1 down, 2
+% right etc.
+
+% \Bk only controls vertical adjustment of the starting and target
+% positions, and keeps the horizontal dimension fixed:
+
+\newcommand{\Bk}[3]{\Bkk{0,#1}{0,#2}{#3}}
+
+% \Bk again has 3 obligatory arguments: the vertical adjustment of the starting
+% position, that of the target position, and the target location. Positive value
+% lifts the starting position, negative value lowers it.
+
+% The simpler version, which you should normally use, only allows for the vertical
+% adjustment of the starting position with its optional argument:
+
+\newcommand{\B}[2][0]{\Bk{#1}{0}{#2}}
+
+% an arrow version of \B:
+
+\newcommand{\ARkk}[3]{\POS[]-(0,4)+(#1)\ar@{->}[#3]+(0,2)+(#2)}
+\newcommand{\ARk}[3]{\ARkk{0,#1}{0,#2}{#3}}
+\newcommand{\AR}[2][0]{\ARk{#1}{0}{#2}}
+
+
+% Dashed, dotted and wavy versions of \B and \AR:
+
+\newcommand{\Bkkdash}[3]{\POS[]-(0,4)+(#1)\ar@{--}[#3]+(0,2)+(#2)}
+\newcommand{\Bkkdot}[3]{\POS[]-(0,4)+(#1)\ar@{.}[#3]+(0,2)+(#2)}
+\newcommand{\Bkkwav}[3]{\POS[]-(0,4)+(#1)\ar@{.}[#3]+(0,2)+(#2)}
+
+\newcommand{\Bkdash}[3]{\Bkkdash{0,#1}{0,#2}{#3}}
+\newcommand{\Bkdot}[3]{\Bkkdot{0,#1}{0,#2}{#3}}
+\newcommand{\Bkwav}[3]{\Bkkwav{0,#1}{0,#2}{#3}}
+
+\newcommand{\Bdot}[2][0]{\POS[]-(0,4)\POS+(0,#1)\ar@{.}[#2]+(0,2)}
+\newcommand{\ARdot}[2][0]{\POS[]\POS-(0,4)\POS+(0,#1) \ar@{.>}[#2]+(0,2)}
+
+\newcommand{\Bdash}[2][0]{\POS[]-(0,4)\POS+(0,#1)\ar@{--}[#2]+(0,2)}
+\newcommand{\ARdash}[2][0]{\POS[]\POS-(0,4)\POS+(0,#1) \ar@{-->}[#2]+(0,2)}
+
+\newcommand{\Bwav}[2][0]{\POS[]-(0,4)\POS+(0,#1)\ar@{~}[#2]+(0,2)}
+\newcommand{\ARwav}[2][0]{\POS[]\POS-(0,4)\POS+(0,#1) \ar@{~>}[#2]+(0,2)}
+
+% Joost Kremers, University of Frankfurt/Main,
+% <j.kremers@em.uni-frankfurt.de>, has kindfully defined a "generalised
+% branch" command that I happily integrate here:
+
+\newcommand{\GBkk}[4]{\POS[]-(0,4)+(#1)\ar@{#4}[#3]+(0,2)+(#2)}
+\newcommand{\GBk}[4]{\GBkk{0,#1}{0,#2}{#3}{#4}}
+\newcommand{\GB}[3][0]{\GBk{#1}{0}{#2}{#3}}
+
+% The branch commands are the same as the \Bkk, \Bk and \B commands, except
+% that they have one more mandatory argument, and the first mandatory argument
+% is the line style, which can be as follows:
+
+% - solid line
+% -- dashed line
+% = double line
+% == dashed double line
+% . dotted line
+% : dotted double line
+% ~ wavy line
+% ~~ dashed wavy line
+
+
+
+
+% Here come a couple of abbreviations for often used branching commands:
+
+% \D goes to the position in the same column, one row below. The optional
+% argument is the vertical adjustment of the starting position.
+
+\newcommand{\D}[1][0]{\B[#1]{d}} 
+\newcommand{\Dk}[2]{\Bk{#1}{#2}{d}}
+
+% \Dk is the \Bk version, i.e., it has two obligatory arguments defining the
+% vertical adjustments of starting position and target position.
+
+\newcommand{\DL}[1][0]{\B[#1]{dl}} 
+\newcommand{\DLL}[1][0]{\B[#1]{dll}} 
+\newcommand{\DLLL}[1][0]{\B[#1]{dlll}} 
+\newcommand{\DR}[1][0]{\B[#1]{dr}} 
+\newcommand{\DRR}[1][0]{\B[#1]{drr}} 
+\newcommand{\DRRR}[1][0]{\B[#1]{drrr}} 
+
+\newcommand{\DLk}[2][0]{\Bk{#1}{#2}{dl}} 
+\newcommand{\DLLk}[2][0]{\Bk{#1}{#2}{dll}} 
+\newcommand{\DLLLk}[2][0]{\Bk{#1}{#2}{dlll}} 
+\newcommand{\DRk}[2][0]{\Bk{#1}{#2}{dr}} 
+\newcommand{\DRRk}[2][0]{\Bk{#1}{#2}{drr}} 
+\newcommand{\DRRRk}[2][0]{\Bk{#1}{#2}{drrr}} 
+
+
+% Abbreviations for binary branches:
+
+
+\newcommand{\V}[1][0]{\DL[#1]\DR[#1]}
+\newcommand{\VV}[1][0]{\DLL[#1]\DRR[#1]}
+\newcommand{\VR}[1][0]{\DL[#1]\DRR[#1]}
+\newcommand{\VL}[1][0]{\DLL[#1]\DR[#1]}
+\newcommand{\VVV}[1][0]{\DLLL[#1]\DRRR[#1]}
+\newcommand{\VVR}[1][0]{\DLL[#1]\DRRR[#1]}
+\newcommand{\VVL}[1][0]{\DLLL[#1]\DRR[#1]}
+\newcommand{\VLL}[1][0]{\DLLL[#1]\DR[#1]}
+\newcommand{\VRR}[1][0]{\DL[#1]\DRRR[#1]}
+
+% Define more if you need them.
+
+% Let's make further abbreviations. A default VP has a \V branch. So let's
+% define \VP accordingly, and likewise Vbar, IP, CP etc.:
+
+\newcommand{\VP}[1][]{\K{VP$_{#1}$}\V}
+\newcommand{\Vbar}{\K[.5]{V$'$}\V}
+
+\newcommand{\IP}[1][]{\K{IP$_{#1}$}\V}
+\newcommand{\Ibar}{\K[.5]{I$'$}\V}
+
+\newcommand{\CP}[1][]{\K{CP$_{#1}$}\V}
+\newcommand{\Cbar}{\K[.5]{C$'$}\V}
+\newcommand{\Nbar}{\K[.5]{N$'$}\V}
+
+\newcommand{\PP}[1][]{\K{PP$_{#1}$}\V}
+\newcommand{\DP}[1][]{\K{DP$_{#1}$}\V}
+
+\newcommand{\AuxP}[1][]{\K{IP$_{#1}$}\V}
+\newcommand{\Auxbar}{\K[.5]{I$'$}\V}
+
+% Nodes reasonably without branch:
+
+\newcommand{\NP}[1][]{\K{NP$_{#1}$}}
+\newcommand{\Nzero}[1][]{\K[1]{N$^{0}_{#1}$}}
+\newcommand{\Vzero}[1][]{\K[1]{V$^{0}_{#1}$}}
+\newcommand{\Izero}[1][]{\K{I$^{0}_{#1}$}}
+\newcommand{\Auxzero}[1][]{\K{I$^{0}_{#1}$}}
+\newcommand{\Czero}[1][]{\K{C$^{0}_{#1}$}}
+\newcommand{\Pzero}[1][]{\K{P$^{0}_{#1}$}}
+\newcommand{\Dzero}[1][]{\K{D$^{0}_{#1}$}}
+
+% Note that all of these commands, except for the Xbar nodes, have an optional
+% argument for an index. If you use indices longer than one letter, you might
+% need to do horizontal adjustment and have to use \K instead.
+
+% This default system only needs new nodes for the terminals. Let's define \T
+% parallel to \K. \T has a vertical branch to the upper node, text is
+% italicised. The optional argument, as before, allows for 
+% horizontal adjustment of the text:
+
+\newcommand{\T}[2][0]{\POS[]\POS+(0,2) \ar@{-}[u]-(0,4)%
+\POS[]\K[#1]{\textit{#2}}}
+
+% An entry could consist of several rows, especially terminal nodes, but we don't
+% want them to influence the lengths of branches. The following defines entries
+% that are typed below an entry. It can be used repeatedly:
+
+\newcommand{\Below}[2][0]{\POS-(0,5)+(0,#1)%
+\save*\hbox{\textnormal{\rule[-6pt]{0pt}{18pt}%
+#2}}\restore}
+
+% The optional argument is the vertical distance to the upper entry. 
+% \below[vertical]{blablabla}
+
+\newcommand{\Belowk}[3][4]{\POS+(#2,#1)%
+\save*\hbox{\textnormal{\rule[-6pt]{0pt}{18pt}%
+#3}}\restore}
+
+% \Belowk command has an additional obligatory argument for horizontal
+% adjustment: \Belowk[vertical]{horizontal}{blablabla}
+
+% Let's define a trace:
+
+\newcommand{\Trace}[1][i]{\K[0.5]{t$_{#1}$}}
+
+
+% Alternative phrase structure tree commands can easily be built with \Treek,
+% \Bkk and \Kk. These are LFG macros:
+
+\newcommand{\Treelfg}[2][0]{\Treek[#1]{3}{#2}} 
+\newcommand{\Klfg}[2][]{\K{$\uparrow _{\textsc{\scriptsize #1}}=\downarrow$}\Below{#2}} 
+\newcommand{\Blfg}[1]{\Bk{-5}{0}{#1}}
+\newcommand{\Vlfg}{\Blfg{dl}\Blfg{dr}}
+
+% Note that \Klfg produces two lines: The inheritance specification and the
+% category label. The optional argument is the grammatical function, which, if
+% available is indexed to the $\uparrow$ in the first line.
+
+% This completes the basics of our trees with the most frequently used
+% functions. Now come some  extensions, in particular, circled nodes with
+% adjusted branches, triangles and arrows linking nodes.
+
+
+% Here come some coloured versions of \K and \B:

+% Extension Nr. 1:
+% Circles and squares around nodes with branches:
+
+% First, we define the circle, to be added after the \K{}, like the branch. It
+% is designed to fit two-letter nodes, like VP a.o. Optional argument: line

+
+%% This is hacked: must be first in the field, before the \K command, and
+%% followed by an empty group, {}.
+
+% Now comes the boring stuff. Branches that start or end at circles are
+% shorter. So let's define macros for all kinds of  short branches. Some
+% commands include the circles already.
+
+% This is a branch that always works, starting point for all branches is the
+% same point on the circle. This makes branches rather short, and changes their 
+% angle:

+\newcommand{\QQ}[1][-]{\POS[]+(0,-1)-(4,4);\POS[]+(0,-1)+(4,4)**\frm{#1}}
+
+% And coloured versions:
+
+\newcommand{\QQred}[2][o]{{}\POS[]+(0,-1)\save *+<1.9pc>[#1][F:red]\txt{}\restore}
+\newcommand{\QQblue}[2][o]{{}\POS[]+(0,-1)\save *+<1.9pc>[#1][F:blue]\txt{}\restore}

+\newcommand{\QQgray}[2][o]{{}\POS[]+(0,-1)\save *+<1.9pc>[#1][F:gray]\txt{}\restore}
+
+% Again: These are not fully functioning. It only works, if the \QQ<color>
+% command is the first one in the field, right after the &, and is followed by
+% an empty group {}. 
+
+% you need branches to and from squared nodes:

+% Sometimes, it is useful to highlight sections of the tree with a
+% rectangle. Let's define such a rectangle:
+
+\newcommand{\QS}[3][-]{{}\POS"#2";\POS"#3"+(4,-4)**\frm{#1}}
+
+% Syntax: \QS[line style]{absolue address of top left corner}{absolue address of
+% bottom right corner}
+% The absolute address is a number pair: Field 1,1 is the top left field. The
+% fields in the first row are 1,1 1,2 1,3 etc. Those in the second row
+% 2,1 2,2 2,3 etc. 
+
+% Extension 2:
+% Drawing links between nodes
+
+% We have two versions, one version, \Link, for links drawn below the
+% tree, and one for links drawn above the tree, \UpLink. The kontrolled
+% version is \Linkk / \UpLinkk:
+
+\newcommand{\Linkk}[3][->]{%
+\POS[]-(3.33,2) \ar@{#1}@/^{#2pc}/[#3]-(1,3.33)} 
+
+\newcommand{\UpLinkk}[3][->]{%
+\POS[]+(1.33,2) \ar@{#1}@/_{#2pc}/[#3]+(2,-2)} 
+
+% \Linkk[style]{curving}{target}
+% The curving ratio controls the curving of the link. In the commands \Link
+% and \UpLink, it is defaulted to 1.33. The curving will differ from tree
+% to tree, so a default might be quite useless.
+% Style can be . for dotted, - for solid, -- for dashed, with leading or
+% following < or > for the arrows. Default is a solid arrow to the target, `->'.  
+
+% Links are defined such that they point from the lower position in the tree
+% to the higher position, not the other way around. But it's all a matter of
+% where they initiate relative to their source and target fields (left/right,
+% top/bottom). Redefine it for your needs.
+
+\newcommand{\Link}[2][->]{%
+  \Linkk[#1]{1.33}{#2}}
+
+\newcommand{\UpLink}[2][->]{%
+\UpLinkk[#1]{1.33}{#2}} 
+

+
+%% Extension in version 1.0.1: adjusting starting and target postions:

+
+% \POS[] is the position of the actual entry
+% \POS"1,1" is the position of the entry in row 1, column 1.
+% \POS[dl] is the position one step down, one step left from current position
+% an arrow consists of an optional start position, the command \ar wit
+% modifiers, and a target position (the target is written without \POS. the
+% simplest arrow is like \ar[l] or \ar[dr] etc. several modifiers are possible:
+% @{style}, where style is:

+% these can be combined with arrows, symbolized by < and >:
+% @{.>} , @{<--} etc.
+% the arrow can be curved, modifiers:
+% @/_/ downwards curved , @/^/ upwards curved
+% an optional argument makes wider or narrower curves:

+% Extension 3:
+% Triangles
+
+% Triangles need the nodes they refer to in the next lower row, in particular,
+% don't forget the node [d] from the insertion point of the triangle. You will
+% get an error otherwise. The text below the triangle is to be inserted in the
+% field [d] from the insertion point.  
+
+% The fully kontrolled command \TRikk has three arguments. The two obligatory
+% arguments for horizontal adjustments of the left and right edge of the
+% triangle, and the optional argument for the vertical adjustment:
+
+% \TRikk[vertical]{left}{right}
+\newcommand{\TRikk}[3][0]{%
+\POS[d]+(-10.4,0)+(-#2,2)+(0,#1)\ar@{-}[d]+(10.4,0)+(#3,2)+(0,#1)

+% Simpler commands are defined on the basis of \TRikk. \TRik has no vertical
+% adjustment: 
+
+\newcommand{\TRik}[2]{\TRikk{#1}{#2}}
+
+% Syntax: \TRik{left}{right}

+% \TRi is a symmetric triangle with the optional argument of the horizontal
+% adjustment, negative value makes it narrower, positive value makes it wider.
+
+\newcommand{\TRi}[1][0]{\TRik{#1}{#1}}
+
+% \TRi[left/right]

+% Extension 5:
+% Arrows in bracketed notations of syntactic structures
+
+% This requires a new matrix, we call it \TExt. Here the inter-column space is
+% set to zero. This means that we have horizontal space with the insertion of
+% a `&'. I.e., we could let arrows point to letters within words.  The
+% controlled version, \Textk, allows you to control for inter-column space
+% with the first mandatory argument. The optional argument adjusts inter-row
+% space.
+
+\newcommand{\TExtk}[3][0]{\raisebox{3pt}{\xymatrix @R=#1pc @C=0pt @M=#2pc {#3}}}
+\newcommand{\TExt}[2][0]{\TExtk{0}{#2}}
+
+% \TExtk has three arguments:
+% \Textk[inter row distance]{inter column distance}{matrix}
+
+% The fields within the \TExt environment are inserted with \Txt or \TXT. They
+% mainly provide a strut to yield correct horizontal alignment. \Txt has a
+% blank before the text, \TXT has none. I.e., if a word is split over two
+% fields, the second part of the word should be introduced with \TXT.
+% Likewise, the first word:
+
+\newcommand{\Txt}[1]{\txt{\rule[-6pt]{0pt}{18pt} #1}}
+\newcommand{\TXT}[1]{\txt{\rule[-6pt]{0pt}{18pt}#1}}
