Re: [F-Script-talk] FSInterpreterView execute

[Peter A P. <p.a...@su...>]

Thanks for that Phillipe. The hack worked fine, but it will be nice  
not to get compiler warnings :)

Another possible convenience method suggestion for the  
FSInterpreterView - a method for creating one word commands. I've  
added one word commands for accessing some of the more commonly used  
methods in my objects by using NSInvocationOperation for a quick  
solution. In the example below, NEAFSCommand is a subclass of  
NSInvocationOperation that I override the -description method to tell  
it to invoke itself and return the returnString (to the  
FSInterpreterView). The interpreter then will invoke the method  
assigned to an NEAFSCommand object when its name is entered in the  
interpreter view.

In the object that has the method I want to make a single word method,  
I include the lines
newDoc = [[NEAFSCommand alloc] initWithTarget:self  
selector:@selector(newDocument:) object:nil];
[(NEAFSCommand *)newDoc setReturnString:@"new Document Created"];
[interpreter setObject:newDoc forIdentifier:@"newDoc"];

The -description method of NEAFSCommand contains:
[[self invocation] invoke];
return returnString;

The reason I'm doing this is because I want to have a set of simple,  
top-level commands for use inside the interpreter that are specific to  
the operation of my app. This also provides a shorthand to create a  
workflow of commands inside a block.
