udapi.block.write.tikz module

Tikz class is a writer for LaTeX with tikz-dependency.

class udapi.block.write.tikz.Tikz(print_sent_id=True, print_text=True, print_preambule=True, attributes=None, as_tree=False, comment_attribute=None, enhanced=False, **kwargs)

Bases: BaseWriter

A writer of files in the LaTeX with tikz-dependency format.

Usage:

udapy write.Tikz < my.conllu > my.tex
# or for 2D tree-like rendering
udapy write.Tikz as_tree=1 < my.conllu > my.tex
pdflatex my.tex
xdg-open my.pdf

Long sentences may result in too large pictures. You can tune the width (in addition to changing fontsize or using minipage and rescaling) with \begin{deptext}[column sep=0.2cm] or individually for each word: My \&[.5cm] dog \& etc. By default, the height of the horizontal segment of a dependency edge is proportional to the distance between the linked words. You can tune the height with: \depedge[edge unit distance=1.5ex]{9}{1}{deprel}

See tikz-dependency documentation for details.

With as_tree=1, there are two options how to visualize deprels: either as labels positioned on the edges by uncommenting the relevant style definition, or by adding deprel to the list of attributes, so deprels are above/below the words. The latter is the default because the edge labels need manual tweaks to prevent overlapping.

Alternatives: * use write.TextModeTrees and include it in verbatim environment in LaTeX. * use write.Html, press “Save as SVG” button, convert to pdf and include in LaTeX.
