Hi there! I am trying to read data from stdin, and am havig some trouble when there is less than a line of data. Here’s some sample code: m = IO::Memory.new STDIN.read_buffering=false m << STDIN.gets_to_end pp! m.to_s If I run it and type “1234<Ctrl+D>” this should print 1234, but doesn’t, it just…

On unix like sysems ctrl D or ^D triggers end of file as below: CTRL D is pressed on an empty line CTRL D is pressed twice on a non-empty line So in your case, you need to press ^D twice for the shell to trigger end of file signal. HIH

Indeed that works, but it’s not how other unix tools work like, for example cat ends immediately on the first Ctrl+d I guess it may be because it’s not just reading stdin but using it as a tty or something. Anyway, good enough, thanks!

[image] ralsina: cat ends immediately on the first Ctrl+d On my machine, I have to hit it twice if it’s not at the beginning of a line.

Reading STDIN always buffered?
