Installation

Dependencies

Ginger depends on

If Python 3 is installed, installing ginger through pip (see below) should take care of most dependencies, except for cairo. Additionally, libginger and libtreebank have no dependencies beyond Python's standard library and can be used independently.

Installing ginger

You don't actually need to install anything if you satisfy the dependencies above, running python3 ginger.py should just work.

However, if you want to have it installed at global level to get the ginger command in your path

  1. Grab the latest release from Github
  2. Unpack it and open a terminal inside the resulting folder
  3. Run python3 -m pip install .

You can also install it directly from the tip (unstable but usually safe) of the master branch whith

python3 -m pip install git+https://github.com/LoicGrobol/ginger/

Test if everything works by running ginger examples/test.conll. The output should be the same as the ASCII-art tree above.

Usage

ginger [--from <format>] <in-file> [--to] [<out-file>]

Arguments

  • <in-file> input file (in CoNLL-U format), - for standard input
  • <out-file> output file, - for standard input (default: -)

Options

  • -f, --from <format> input file format, see below (default: guess)
  • -t, --to <format> output file format, see below (default: ascii)
  • -h, --help Get some help

Examples

  • Print to stdout
ginger examples/test.conll
  • Assume CoNLL-X for input format
ginger -f conllx spam.conllx
  • Output TikZ code
ginger examples/test.conll -t tikz
  • Print to a file
ginger examples/test.conll examples/output.asciiart
  • Pipe in and out
cat examples/test.conll | ginger - | less
  • Get help
ginger --help

Input formats

  • guess Try to guess the file format, defaults to CoNLL-U

CoNLL

  • conllu CoNLL-U v2 format
  • conllx CoNLL-X format
  • conll2009_gold CoNLL-2009 format
    • Takes only the gold columns into account.
    • The P- and -PRED attributes are preserved in the misc attribute of the intermediate CoNLL-U tree.
  • conll2009_sys CoNLL-2009 format
    • Takes only the predicted columns into account.
    • The gold columns and the -PRED attributes are preserved in the misc attribute of the intermediate CoNLL-U tree.

Software

Formats used by mainstream NLP tools

  • talismane Outputs of Talismane
  • mate_gold Input/Output of mate-tools (actually an alias for conll2009_gold)
  • mate_sys Input/Output of mate-tools (actually an alias for conll2009_sys)

Output formats

Treebanks

The input must be either the path to an existing file or - for standard input. The data that it contains must be in one of the following formats:

Note : no real effort is made to preserve informations that are not relevant to Universal Dependencies, so this might be information-destructive, e.g. if converting from CoNLL-2009 to itself, the P- attributes will be dropped.

Text formats

To use these formats, the output destination must be either a file and thus must not be the path to an existing directory, or - for the standard output.

  • ascii ASCII-art (using unicode characters, because, yes, we are subversive)
  • tikz TikZ code. Use the positioning, calc and shapes.multipart tikz libraries
    • The output is only the \tikzpicture part, not a whole compilable document, there is an example of such a document in example.
    • The code is quite verbose since we chose to rely on TikZ' own arithmetic capabilities in order to allow easier edition and reuse of the generated code.

Image formats

To use these formats, the output destination must be either a directory and thus must not be the path of an existing file, or - for the standard output, in which case the byte streams corresponding to different trees will be separated by NULL bytes.

  • png
  • svg
  • pdf

Development

Development and releases on Github.

Further notes

  • When importing non-CoNLL-U treebanks, node forms with spaces are considered to be fixed expressions, and are treated according to UD guidelines by splitting them in single-token nodes linked by fixed dependencies This mean that the exceptions mentioned in the UDv2 guidelines are not supported for those imports. They are supported when importing from CoNLL-U, though.
