• Xcode C++ debugging

  - by mousebird

  I'm looking for a way to have the Xcode IDE pick up on the contents of my weird Boost template classes. Basically, classes complex enough that Xcode can't display their contents correctly. Is there something like the Objective C -description method or toString() in Java that Xcode will look for? At the moment I'm just implementing print() methods and invoking them in gdb, but that's likely to confuse other developers.

• how to separate debug and release mode code

  - by john

  during debug mode or while i am doing testing, i need to print lost of various information, so i use this method ifdef TESTING // code with lots of debugging info else // clean code only endif // TESTING` Is this the good method, or is there any other simple and elegant method. But this way, I am repating the same code in two places and if anything is to be changed later on in the code, I have to do it in both places, which is time consuming and error prone. Thanks. I am using MS Visual Studio.

• Apple script Editor, write message to the "Result" window

  - by Patrick

  I am using the Mac OS X Apple Script Editor and (while debugging) instead of writing a lot of display dialog statements, I'd like to write the results of some calculation in the window below, called "Result" (I have the German UI here, so the translation is a guess). So is there a write/print statement that I can use for putting messages in the "standard out" window? I am not asking to put the messages in a logfile on the file system, it is purely temporary.

• Word 2007 macros: is there an OnPrint event I can attach a macro to?

  - by notnot

  I'm looking to do a formatting check on word files before they get sent to the printer and it needs to be completely transparent to the user (no extra controls, just using the standard print options available through the UI). Is there an OnPrint or BeforePrint event, or something that can be used in that respect which I could attach a macro to, the same way I can with Open, Close, or Save? This feels like it should be simple... but those are famous last words. Thanks in advance, Rob

• file output in python giving me garbage

  - by Richard

  When I write the following code I get garbage for an output. It is just a simple program to find prime numbers. It works when the first for loops range only goes up to 1000 but once the range becomes large the program fail's to output meaningful data output = open("output.dat", 'w') for i in range(2, 10000): prime = 1 for j in range(2, i-1): if i%j == 0: prime = 0 j = i-1 if prime == 1: output.write(str(i) + " " ) output.close() print "writing finished"

• One liner in Ruby for displaying a prompt, getting input, and assigning to a variable?

  - by Jarsen

  Often I find myself doing the following: print "Input text: " input = gets.strip Is there a graceful way to do this in one line? Something like: puts "Input text: #{input = gets.strip}" The problem with this is that it waits for the input before displaying the prompt. Any ideas?

• What is the difference between using $1 vs \1 in Perl regex substitutions?

  - by Mr Foo Bar

  I'm debugging some code and wondered if there is any practical difference between $1 and \1 in Perl regex substitutions For example: my $package_name = "Some::Package::ButNotThis"; $package_name =~ s{^(\w+::\w+)}{$1}; print $package_name; # Some::Package This following line seems functionally equivalent: $package_name =~ s{^(\w+::w+)}{\1}; Are there subtle differences between these two statements? Do they behave differently in different versions of Perl?

• Jython: is there a clean way to implement a Java interfaces with function references?

  - by auramo

  I know that I can implement a Java interface with Jython like this: class MyListener (Listener): def foo(self, event): print(str(event)) Python has first-class functions so that seems like an overkill - especially for interfaces with one method. Is there a way to just pass a lambda or function which implements a single method in an interface instead?

• Is it good practice to name variables differently when defining more than one function?

  - by John

  For example, in this simple function where fun1 takes as input two numbers, adds them together and passes them to function 2 for printing the output. var1_in is local to each function, so is it OK to use the name var1_in in both functions, or is it better practice to call them different things? fun1 <- function (var1_in, var2_in) { var3 = var1_in + var2_in fun2(var3) } fun2 <- function (var1_in) { var4 = var1_in print(var4) }

• Objective-C retain counts in dealloc

  - by Michael Waterfall

  I'm seeing something fairly strange here, I've got breakpoints set in various dealloc methods in my app, and on inspection, the retain counts of the object self varies from 1 to 0. When dealloc is called, will the retain count of the object be set to 0 already? I'm using print (int) [self retainCount] in the console to test this. The 0's seem to only appear in the dealloc of my NSOperation's that are being run in an NSOperationQueue. Any idea why this is?
