PROGRAM:

NAME

botch-graph-sources - find all sources (vertices without predecessors) in a graph in
GraphML or dot format

SYNOPSIS

botch-graph-sources [options] [ingraph] [outgraph]

DESCRIPTION

Extract the subgraph of all sources (vertices without predecessors) in the input graph.

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.

OPTIONS

-h, --help
Display help.

-v, --verbose
Be verbose.

EXAMPLE

Find all source packages that build depend on "texlive-binaries:amd64
(=2015.20150524.37493-5)".

Using package selection and reverse dependency cone computation by ceve:

dose-ceve -r "texlive-binaries:amd64 (= 2015.20150524.37493-5)" --deb-native-arch=amd64 -G pkg -T grml deb://Packages debsrc://Sources \
| botch-graph-sources - - \
| botch-graph2text - "{realpackage} (= {realversion})" --vertices type:src \
| sort

Using package selection and ancestor vertex computation by botch:

dose-ceve --deb-native-arch=amd64 -G pkg -T grml deb://Packages debsrc://Sources \
| botch-graph-ancestors - - --target realpackage:texlive-binaries:amd64 realversion:2015.20150524.37493-5 \
| botch-graph-sources - - \
| botch-graph2text - "{realpackage} (= {realversion})" --vertices type:src \
| sort
