Detailed Description

Class to parse a PSCF command script.

The Script class can read a command script file and store its contents in a form that allows particular commands to be accessed and modified.

**Construction and Parsing:**a

The constructor can take the name of a command file or an open file object as a parameter, and will read, parse and store the contents of the specified file.

Example: To parse a command file named 'command', one could enter

s = Script('command')

Accessing individual commands:

A Script object is a container for a list of child Command objects. Each command corresponds to one line in the command script, in which the first field is the label. Individual Command objects within a Script object can be accessed in either of two ways:

• Command objects may be accessed by integer index using the square bracket notation for elements of a python list. If s is a Script, then s[2] is the 3rd command in the script.
• Commands may also be accessed using square bracket notation using the command name (or label) string as a key. If the script contains several commands with the same name, a list of Command objects is returned, listed in the order in which they appeared.

String representation of individual Commands objects can be printed using the str() or print functions. Values of arguments of individual Command objects may then be accessed or modified using the param and setParam methods of class Command (see below).

Constructor & Destructor Documentation

__init__()

pscfpp.command.Script.__init__	(		self,
			filename = None )

Constructor.

If supplied with a parameter "in" that is an open file or a file name string, this function reads and parses that command file and stores the contents in the resulting object.

If the parameter "in" is absent or equal to None, an empty object is created and returned.

Parameters

filename

file name or open file object for input command file
