[F-Script-talk] Re: How do you print text to the console while running a Cocoa script?

[Philippe M. <pm...@ac...>]

The method "log:" in class System can be used to achieve the same=20
effect than a call to NSLog() in Objective-C (i.e., logging a message=20
on stderr) . A predefined instance of System, named "sys" is always=20
defined. Example:

sys log: 'scrWidth''s value is ' ++ scrWidth printString

Note that NSLog() is used internally by the log: method.

--------

F-Script does not define any new API to print something to stdout. You=20=

can use the standard Cocoa classes, or roll your own. For instance,=20
using the Cocoa classes:

NSFileHandle fileHandleWithStandardOutput writeData:('hello, world'=20
dataUsingEncoding:NSASCIIStringEncoding).

This will print "hello, world" to stdout.

Best,
