=head1 NAME



ud - TrEd extension to display and edit Universal Dependencies



=head1 DESCRIPTION



=head2 Stylesheet



=over 2



=item *



The word form is displayed as a black label of each node, the label is grey

for empty nodes. The part of speech tag is displayed in dark cyan.



=item *



As each non-root node must have a single parent, the dependency type is shown

as a blue label of the child node.



=item *



The lemma is displayed only if it is different from the word form to narrow

the trees.



=item *



If the enhanced dependency is the same as the basic one, it is not shown at

all. If there is an additional dependency, it is shown as an orange curved

arrow with the dependency type shown in magenta near the start of the arrow.

If the basic dependency is not duplicated in the enhanced one, the tree edge

is coloured in cyan instead of grey and is thinner. If the enhanced dependency

has the same parent as the basic one but a different type, the type can be

displayed in two ways: if it begins with the basic type, only the extra

characters are displayed in blue violet, otherwise, it is displayed full in

violet after a slash.



=item *



An expanded contraction is represented by a dashed area covering the

individual words.



=back



=head2 Editing



=over 2



=item *



Dropping node C on node C attaches node C to node C. An enhanced

dependency is created together with the basic one, if an enhanced dependency

existed to the old or new parent, it is removed.



=item *



Dropping node C on node C while pressing C toggles existence of

an enhanced dependency of node C on node C. If a dependency was created,

the user is asked for its type. This works even when C already is C's

parent.



=item *



Dropping node C on node C while pressing C attaches node C to

node C without creating an enhanced dependency. If an enhanced dependency

existed to the old or new parent, it is removed.



=item *



Pressing C opens a dialog box to edit the current node's dependency type.

If previously an enhanced dependency of the same type as the basic dependency

existed, it is changed together with it, otherwise, it stays unchanged.



=item *



Pressing C inserts a new null node as the leftest son of the

current node, the user is asked for its form.



=item *



Pressing C or C adds the current node to a

contraction group. If none of the neighbouring nodes is in a group, a new

group is created and the user is asked for its form. If the nodes are already

in a group, the group is deleted.



=item *



Pressing C, C, and C
 edits lemma, features, and POS, respectively.
