Specification for writer > gv-writer

gv-writer

GV writer presents the results in a simple graphical form. For this purpose, it uses GraphViz library - a library for creating graphs (hence GV acronym).

If gv-writer is not available, you can obtain the graph representation of the lattice in DOT format using dot-writer.

GV-writer shows the content of the lattice as a directed graph. The text and various annotations are represented by edges of the graph. For clarity, symbol edges are not shown by default. To see all edges, use the --show-symbol-edges switch. The edges of different layer tags are distinguished by different colors. To see the tags' names, use the --show-tags switch. To disable coloring, use the --no-color switch. The range of displayed edges can be restricted with the --tags option, which allows to specify the visible layer tags. When this option is used, only edges with specified layer tags are shown.

GV-writer tries to align lattice vertices left to right. This default behavior can be disabled by the --no-align switch.

The default output format is SVG, but many other formats are also available. A different output format can be set by the --format option. The list of available output formats: canon, dot, eps, fig, gd(:cairo,:gd), gd2(:cairo,:gd), gif(:cairo,:gd), gv, jpe(:cairo,:gd), jpeg(:cairo,:gd), jpg(:cairo,:gd), pdf, plain, plain-ext, png(:cairo,:gd), ps(:cairo,:ps), ps2, svg(:cairo,:svg), svgz, tk, vml, vmlz, wbmp(:cairo,:gd), xdot. Detailed description of output formats can be find on http://www.graphviz.org/content/output-formats

GV-writer can be also used in the tree mode, which can be switched on with the --tree option. Tree mode allows for displaying the dependency tree. When in the tree mode, lattice edges are displayed as tree nodes, and the dependencies between lattice edges are depicted as arrows. Alternative dependencies are marked with consecutive numbers. This mode is particularly useful for displaying parse trees.

Options

Allowed options:
  --disambig            choose only one partition
  --format arg (=svg)   choose output format
  --no-align            allow nodes to be not aligned left to right
  --no-color            make output monochromatic (black on white)
  --show-tags           print edges' layer tags
  --show-symbol-edges   show symbol edges
  --tags arg            show only edges tagged with specified tags
  --tree                show dependencies between edges instead of the content 
                        of the lattice
