A command-line utility to plot Conda dependency graphs.
Visualizing the dependency graph of Conda packages comes in handy for
understanding why a parcticular package is installed. conda-depgraph
plots the graph on the command line, so there's no need to fire up a Jupyter
notebook.
For example, listing all the packages that (indirectly) depend on MKL in a particular environment is as easy as
$ conda depgraph in mkl┌──────────┐ ┌──────┐
│matplotlib│ │pyfits│
└─┬────────┘ └───┬──┘
│ │
│ ┌────────────┘
│ │
v v
┌─────┐ ┌──────────┐
│numpy│ │numpy-base│
└──┬──┘ └─┬────────┘

└────┐ │

conda-depgraph can be installed as follows:
$ conda install -n base -c omegacen conda-depgraphIt can either be installed into its own conda environment, or into the base environment.
Installing it in the base environment has the benefit that the
conda depgraph command is available in all other environments. However,
you will have to make sure that java is available on $PATH.
Installing it in its own environment automatically ensures it can find java,
but then you will have to activate that environment before you can run
conda depgraph.
After installation a new Conda command is available:
$ conda depgraph [--help]
[--from-channels]
[--from-env [--name=<ENV_NAME>] [--prefix=<ENV_PATH>]]
[--output-names] [--output-graph] [--output-graphml]
[in [--distance=<DISTANCE>] <PACKAGE>]
[out [--distance=<DISTANCE>] <PACKAGE>]
[inout [--distance=<DISTANCE>] <PACKAGE>]depgraph can plot dependency graphs from either cached repository data,
or from an existing Conda environment. The latter is the default behaviour. If
the target environment is not specified via either --name or --prefix,
the current environment is used.
The subcommands (in, out, inout) restrict the output to a subgraph
of the full dependency graph of the environment. The subcommands can be
arbitrarily nested to iteratively restrict the output graph.
