Having the input and layout side by side [duplicate]

I have just installed latex on my mac. I opened the texwork and I can type in latex script there, whenever I compile it, I will get an output.

But is it possible to have the output instantly standing side by side, so that when I type, I can see the change immediately?

Do I have to get any other plugin?

That is not the way LaTeX is working. It shows you after you complied the changed code the result, not simultanly ... –  Kurt Sep 10 '13 at 15:04

ok.. so I have to compile everytime. So is there a good way to set up the workspace? the happiest way to work with latex? –  Timothy Leung Sep 10 '13 at 15:16
TexStudio provieds a layout which can arrange source and output beside each other an automatically updates the output on compilation. It has even a preview function texstudio.sourceforge.net –  samcarter Sep 10 '13 at 15:29
More or less a duplicate of Automatically start the necessary pdflatex runs if .tex has changed (MacOS X)?. For TeXShop, Claus Gerhardt's Flashmode approximates this behaviour. –  Alan Munn Sep 10 '13 at 15:38
