Mike Zamansky has posted another video in his Using Emacs Series. This time it’s about configuring Irony to get completions for C++. Personally, I don’t use things like company-mode and irony-mode because I don’t like having random buffers pop up offering to complete whatever I’m writing. That’s a minority position, I know, so if you do like the idea of completions and you write in C++, you should definitely take a look at Zamansky’s video on how to get things working.
The video is only 3 minutes, 48 seconds so you should be able to sneak it in no matter how busy your day. As always with the Using Emacs videos, it’s well worth your time even if you aren’t particularly interested in completions.
