I spent a lot of time in text editors and have been using Sublime Text for years; Atom recently caught my attention as a completely free alternative (though Sublime’s trial period is currently unlimited…) that has a huge community behind it and good support.
One of the biggest things that I found off-putting was the lack of autocompletion – or autoclose a tag – via typing a </ – something I had gotten rather used to in Sublime which does that by default.
Turns out that one of the best bits of Atom is the packaging system, and there is a package for that. It’s called Less Than Slash and can be installed from the Atom package manager which comes with it (open it with CMD+, on a Mac).
Ten seconds later the package is installed and I have my autocomplete back! Happy camper.
