11.34.1. Description

The tc-converter program is used to convert the transformation catalog from one format to another.

Currently, the following formats of transformation catalog exist:

Text

This is a easy to read multi line textual format.

A sample entry in this format looks as follows:

tr example::keg:1.0 {
        site isi {
        profile env "JAVA_HOME" "/bin/java.1.6"
        pfn "/path/to/keg"
        arch  "x86"
        os    "linux"
        type "installed"
    }
}

YAML

This is YAML-based format. A sample entry in this format looks as follows:

pegasus: "5.0"
transformations:
 -
  name: "keg"
  sites:
   -
    name: "condorpool"
    type: "installed"
    pfn: "/path/to/keg"
    arch: "x86_64"
    os.type: "linux"

11.34.2. Options

-Dprop=value

The -D option allows an experienced user to override certain properties which influence the program execution, among them the default location of the user’s properties file and the PEGASUS_HOME location. One may set several CLI properties by giving this option multiple times.

The -D option(s) must be the first option on the command line. CLI properties take precedence over the file-based properties of the same key.

-I fmt; –iformat fmt

The input format of the input files. Valid values for the input format are: Text or YAML.

-O fmt –oformat fmt The output format of the output file. Valid values for the output format are: Text or YAML

-i infile[,*infile*,…] –input infile[,*infile*,…] The comma separated list of input files that need to be converted to a file in the format specified by the –oformat option.

-o outfile; –output outfile: The output file to which the output needs to be written out to.

11.34.2.1. Other Options

-v; –verbose: Increases the verbosity of messages about what is going on. By default, all FATAL ERROR, ERROR , CONSOLE and WARNINGS messages are logged.
-q; –quiet: Decreases the verbosity of messages about what is going on. By default, all FATAL ERROR, ERROR , CONSOLE and WARNINGS messages are logged.
-V; –version: Displays the current version number of the Pegasus Workflow Planner Software.
-h; –help: Displays all the options to the pegasus-tc-converter command.
