The Foundation function NSFullUserName(). -- Shane Stanley <sstanley@...> <www.macosxautomation.com/applescript/apps/>, <latenightsw.com>

Ah, hidden in plain sight! Thanks G.

Hi, I’m using NSTask to ‘talk to’ a command line executable that is embedded in my app. I use NSPipe as its stdIn and stdOut channels. When I run the code under Xcode, it works fine. When I

For some reason lost in ancient Unix history, if you write to a file-descriptor that’s been closed at the other end, a SIGPIPE signal is raised. This will by default kill your process. It’s

Before running your app open the Console app and put the process name of your app in the search bar. The run your app. I believe you'll see your output. It seems with the new log system is you

OK, makes (some) sense, thanks. I’m wondering why the file descriptor would be ‘closed at the other end’ though - does that mean one of us (the command line tool is not my code but I am

Well, this is so far a blind alley. I can’t find any mention of functions called signal() or ioctl() in the current (Xcode 8) documentation browser. But then, it seems we’ve lost the ability to

A broken pipe usually means that one end of the connection has been closed for one reason or another. You don’t show the actual read and write code, but that is most likely where the problem occurs.

Look at fcntl() (man fcntl). It has an operation parameter of F_SETNOSIGPIPE and F_GETNOSIGPIPE to manage the SIGPIPE signal handling on a file descriptor. Won’t find it in the Xcode

Hi all, At the moment I am saving tiff files in a one-liner using [[myNSImage TIFFRepresentation] writeToFile:atomically:]. I am considering a change to write rather large multi-page tiff files

Hi, Can anyone recommend a light weight Image Creation and Editing App for the Mac? I’d like to be able to create images with fixed dimensions and background colour and be able to resize

How about Gimp?

Um... I might just write code to do that. The 'hardest' thing is probably to get text positioning right. For general image manipulation I use Pixelmator. I like it but I wouldn't exactly call it

Try canva.com. They have a reasonable free account for graphics editing online, apparently they have an iOS app too, although I've never tried that. Sandor

I’ve been happy with Acorn for those purposes for years. The documentation is great too. https://flyingmeat.com Jim Crate

It does seem absurd that the most fundamental APIs — the C standard library and POSIX/Darwin system calls — aren’t supported by Xcode’s documentation features. Especially since the header

Jens; Thank you for the opportunity to expound on this. See below… A look at the discussion for NSFileHandle’s writeData: method provides the following: "This method raises an exception if the

Apologies if this is a dumb question, but I'm wondering whether we'll still be able to call NSFileManager api's like attributesOfItem and get back things like NSFileReferenceCount and the like. Does

If it did, it would break most apps, so no. —Jens

Breaking stuff isn’t always a red line for Apple, but from your reaction I’ll take it that there’d have been an righteous outcry by now were it the case. I’ve had my head stuck in the sand as
