Extension - Open Scripting Architecture
This section describes functions which support the Open Scripting Architecture of Mac OS, i.e. a system-level mechanism which supports different computer languages such as AppleScript.
Functions
doscript
Execution of a script by another Mac OS application.
Syntax
doscript(target, script) reply = doscript(target, script)
Description
doscript(target,script) requests the application identified by the four-character signature in string target to execute the script in string script. If doscript has an output argument, a reply is returned in a string.
Data exchange involved by doscript is performed with AppleEvents, a process-to-process communication mechanism specific to Mac OS. Not all applications accept the doscript AppleEvent.
Example
Ask Matlab to perform a matrix inversion and inverse it back with LME. Note how the precision argument of the Matlab function num2str is used to retrieve all significant digits; in LME, dumpvar could be used instead.
reply = doscript('MATL','disp(num2str(inv([2,3;1,7]),16))')
reply =
0.6363636363636364 -0.2727272727272727
-0.09090909090909091 0.1818181818181818
Mi = eval(['[', reply, ']'])
Mi =
0.6364 -0.2727
-9.0909e-2 0.1818
norm(inv(Mi) - [2,3;1,7])
ans =
1.5249e-15
osascript
Execution of a script.
Syntax
osascript(script) osascript(script, osaName) reply = osascript(...)
Description
osascript(script) requests the default OSA scripting language (normally AppleScript) to execute script. A second input argument can be used to specify the name of the scripting language (such as 'AppleScript' or 'JavaScript', depending on which OSA component is installed on the computer; see osascriptlist). An output argument can be used to request a string reply.
Example
Display a dialog box and get the label of the button clicked by the user:
dlg = ['display dialog "Which color?" ',...
'buttons {"Blue", "Red"} ',...
'default button "Blue"'];
s = osascript(['the button returned of (', dlg, ')'])
s =
Red

osascriptlist
List of available OSA scripting languages.
Syntax
list = osascriptlist
Description
osascriptlist gives the list of scripting languages which are installed and can be used with osascript.
