As of Atom version 0.116.0, we now enable the new React editor component by default.

Today, we are happy to announce that Atom is now available on Windows. This is an alpha release that supports Windows 7 and Windows 8.

Today, we’re excited to announce that we are open-sourcing Atom under the MIT License. We see Atom as a perfect complement to GitHub’s primary mission of building better software by working together. Atom is a long-term investment, and GitHub will continue to support its development with a dedicated team going forward. But we also know that we can’t achieve our vision for Atom alone. As Emacs and Vim have demonstrated over the past three decades, if you want to build a thriving, long-lasting community around a text editor, it has to be open source.

Looking to get your Atom package building on CI so that pull requests are updated automatically when tests pass or fail?

Back in Atom’s early days, the decision was made to support TextMate grammars for syntax highlighting. There were over 100 existing languages supported under the TextMate org. and Oniguruma regular expressions provided great power for complex pattern matching.

Have you ever used Atom and wondered what all the colors in the gutter, tree view, and status bar mean?
