eww.parser

We need to make some modifications to optparse for our environment. This module creates a subclass of optparse with the necessary changes.

class eww.parser.Opt(*opts, **attrs)

Bases: optparse.Option

We don’t need to change anything here; we’re subclassing this for consistency.

class eww.parser.Parser(*args, **kwargs)

Bases: optparse.OptionParser

Our lightly modified version of optparse.

__init__(*args, **kwargs)

Init. The only change here is forcing the help option off. We could do this at instantiation, but it’s cleaner to do it here.

error(msg)

We override error here to prevent us from exiting. Optparse does not expect this to return, but that’s not really a problem for us since each command can be abstractly considered a different, new script.

Parameters:msg (str) – The error message that will be passed to the ParserError exception. Raises:ParserError – Raised when a command cannot be parsed.

exception eww.parser.ParserError

Bases: exceptions.Exception

We create a custom exception here to be raised on error. That way we can safely handle parser errors and do something useful with them.
