Static Job Specification Synopsis

Tractor Job files are typically represented as TCL scripts using special job definition operators recognized by the Tractor job parser. This format was first introduced for the Alfred system, and Tractor remains compatible with nearly all Alfred constructs.

Tractor also supports an evolving set of JSON job specification formats, described in a separate document.

Tractor job input scripts (in alfscript format) are composed of expressions using the following Tcl operators:

Job [options]

Task {title} [options]

RemoteCmd {launch_expr} [options]

Cmd {launch_expr} [options]

Instance {task_title_to_reference}

Iterate varname -from n -to m -by i -template {script} [options]

Assign varname {value_string}

See the Operator Details for detailed descriptions of options and operator syntax.
