NAME

botch-graph2text - for each vertex in a graph print a formatted line on standard output

SYNOPSIS

botch-graph2text [options] [ingraph] formatstring

DESCRIPTION

Given a formatstring of the form "{attr1} {attr2}...", print a line with this format for every vertex in the graph, replacing "{attr}" placeholders with the value of the attribute "attr" for that vertex. If no attribute with name "attr" was found, then the placeholder "{XXX}" remains in the output string. To write a literal opening or closing curly brace, type them twice, respectively. The special placeholder "{__ID__}" is replaced with the vertex identifier.

If the positional arguments is omitted, then read GraphML or dot from standard input. Passing a '-' as either argument, explicitly specifies to read the input from standard input. The input graph type will be determined automatically.

OPTIONS

-h, --help

Display help.

--vertex=VERT

This option picks the set of vertices that will be output. The VERT argument is a key/value pair (separated by a colon) of a graph attribute and its value. By default (without this option), all vertices of the graph are considered.

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

This option can be specified more than once. The final set of vertices is chosen such that all vertices match all key/value pairs. Multiple --vertex options thus form a logical conjunction (they are AND-ed together).

-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})" --vertex 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})" --vertex type:src \
                | sort
