say, interprocess communication (list of parameters)

The macro say is executed like this:

 
p09/door/haso107tk.01 [22]: say a message to the user
say: a message to the user

The text is sent via a door to spock or SardanaMacroExecutor. This communication path has certain disadvantages: the message might get lost in the output stream generated during a scan and the user cannot enter 'say' while a scan is active. Therefore, consider to use SardanaChat.py, see 7.2.2.

#!/usr/bin/env python

from sardana.macroserver.macro import macro, Macro, Type

class say(Macro):
    ”'
    say prints a message being sent via a door to spock or the MacroExecutor
    ”'
    param_def = [ ["words", [[ 'word',  Type.String, None, 'value']], 
                   None, "a line to be printed"]]
    def run(self, words):

        self.output( "say: %s" % " ".join( words).strip())
        # blue
        self.info( "say (info): %s" % " ".join( words).strip())
        # yellow
        self.warning( "say (warn): %s" % " ".join( words).strip())
        # read
        self.error( "say (error): %s" % " ".join( words).strip())

        return
