       filesystem. pegasus-config can be used to find libraries such as the DAX generators.

DESCRIPTION

       pegasus-config is used to find locations of Pegasus system components. The tool is used
       internally in Pegasus and by users who need to find paths for DAX generator libraries and
       schemas.

OPTIONS

       -h, --help
           Prints help and exits.

       -V, --version
           Prints Pegasus version information

       --perl-dump
           Dumps all settings in perl format as separate variables.

       --perl-hash
           Dumps all settings in perl format as single perl hash.

       --python-dump
           Dumps all settings in python format.

       --sh-dump
           Dumps all settings in shell format.

       --bin
           Print the directory containing Pegasus binaries.

       --conf
           Print the directory containing configuration files.

       --java
           Print the directory containing the jars.

       --perl
           Print the directory to include into your PERL5LIB.

       --python
           Print the directory to include into your PYTHONLIB.

       --python-externals
           Print the directory to the external Python libraries.

       --schema
           Print the directory containing schemas.

       --classpath
           Builds a classpath containing the Pegasus jars.

       --noeoln
           Do not produce a end-of-line after output. This is useful when being called from
           non-shell backticks in scripts. However, order is important for this option: If you
           intend to use it, specify it first.

       --local-site [d]
           Create a site catalog entry for site "local". This is only an XML snippet without root
           element nor XML headers. The optional argument "d" points to the mount point to use.
           If not specified, defaults to the user’s $HOME directory.

       --full-local [d]
           Create a complete site catalog with only site "local". The an XML snippet without root
           element nor XML headers. The optional argument "d" points to the mount point to use.
           If not specified, defaults to the user’s $HOME directory.

EXAMPLE

       To set the PYTHONPATH variable in your shell for using the Python DAX API:

           export PYTHONPATH=`pegasus-config --python`

       To set the same path inside Python:

           config = subprocess.Popen("pegasus-config --python-dump", stdout=subprocess.PIPE, shell=True).communicate()[0]
           exec config

       To set the PERL5LIB variable in your shell for using the Perl DAX API:

           export PERL5LIB=`pegasus-config --perl`

       To set the same path inside Perl:

           eval `pegasus-config --perl-dump`;
           die("Unable to eval pegasus-config output: $@") if $@;

       will set variables a number of lexically local-scoped my variables with prefix "pegasus_"
       and expand Perl’s search path for this script.

       Alternatively, you can fail early and collect all Pegasus-related variables into a single
       global %pegasus variable for convenience:

           BEGIN {
               eval `pegasus-config --perl-hash`;
               die("Unable to eval pegasus-config output: $@") if $@;
           }
