botch-graph-ancestors - find all ancestors of a vertex in a graph in GraphML or dot format


botch-graph-ancestors [options] [ingraph] [outgraph] --target TARGET [TARGET ...]


Extract the subgraph of all ancestors of a specific node in the input graph.

The --target option is mandatory. Since it can take more than one argument, it has to come
after the positional arguments.

If either (or both) of the positional arguments is/are omitted, then read GraphML or dot
from standard input and/or write GraphML or dot to standard output, respectively. Passing
a '-' as either argument, explicitly specifies to read the input from standard input and
write the output to standard output, respectively.

The input graph type will be determined automatically. If the output graph is given as a
filename, then the output type will be GraphML if the filename ends with .xml and dot if
the filename ends with .dot. If the output is done on standard output then it will happen
in the same format as the input graph.


-h, --help
Display help.

--target=TARGET [TARGET ...]
key:value pairs to match the target vertex

The special key "__ID__" allows one to select the unique vertex identifier.

-v, --verbose
Be verbose.


Extract the subgraph of all ancestors of a binary packages vertex with name "build-
essential" and version "11.7".

botch-graph-ancestors --target name:build-essential version:11.7 type:bin < in.xml > out.xml

or giving input and output as positional arguments:

botch-graph-ancestors in.xml out.xml --target name:build-essential version:11.7 type:bin

Find all source packages that build depend on "texlive-binaries:amd64
