As a result, we’ve decided to sunset Atom so we can focus on enhancing the developer experience in the cloud with GitHub Codespaces. As new cloud-based tools have emerged and evolved over the years, Atom community involvement has declined significantly. Why are we doing this?Ītom has not had significant feature development for the past several years, though we’ve conducted maintenance and security updates during this period to ensure we’re being good stewards of the project and product. On June 8, 2022, we announced that we will sunset Atom and archive all projects under the organization on December 15, 2022. While that goal of growing the software creator community remains, we’ve decided to retire Atom in order to further our commitment to bringing fast and reliable software development to the cloud via Microsoft Visual Studio Code and GitHub Codespaces. When we introduced Atom in 2011, we set out to give developers a text editor that was deeply customizable but also easy to use-one that made it possible for more people to build software. NovemUpdate: We’ve since updated our blog post to include additional information about what you can expect after the sunset of Atom on December 15, 2022. Read more on our blog, including next steps for impacted Desktop users. To keep using Atom, users will need to download a previous Atom version. These versions of Atom will stop working on February 2. Revoking these certificates will invalidate some versions of Atom. As a preventative measure, we will revoke the exposed certificates used for the Atom application. After a thorough investigation, we have concluded there was no risk to services as a result of this unauthorized access.Ī set of encrypted code signing certificates were exfiltrated however, the certificates were password-protected and we have no evidence of malicious use. On December 7, 2022, GitHub detected unauthorized access to a set of repositories used in the planning and development of Atom. *: What we were doing was plain wrong and "approximate" is a very nice word for it :).JanuUpdate: Update to the previous version of Atom before February 2 For the line below, we would get the following tokens from our hand-written tokenizers: tokens = In the past, we wrote tokenizers by hand (there is no feasible way to interpret TextMate grammars in the browser even today, but that's another story). One requirement we had was to reduce memory usage. It was shipped in the form of the Monaco Editor in various Microsoft projects, including Internet Explorer's F12 tools. The code for the editor in VS Code was written long before VS Code existed. More rarely, typing on a line results in a retokenization/repaint of the current line and some of the ones below (until an equal end state is encountered): Most of the time, typing on a line results in only that line being retokenized, as the tokenizer returns the same end state and the editor can assume the following lines are not getting new tokens: This is a technique used by many tokenization engines, including TextMate grammars, that allows an editor to retokenize only a small subset of the lines when the user makes edits. A tokenizer can store some state at the end of a tokenized line, which will be passed back when tokenizing the next line. ![]() Tokenization in VS Code (and in the Monaco Editor) runs line-by-line, from top to bottom, in a single pass. It is the one feature that turns a text editor into a code editor. Tokens are assigned to source code, and then they are targeted by a theme, assigned colors, and voilà, your source code is rendered with colors. Syntax Highlighting usually consists of two phases. TL DR TextMate themes will look more like their authors intended in VS Code 1.9, while being rendered faster and with less memory consumption. Visual Studio Code version 1.9 includes a cool performance improvement that we've been working on and I wanted to tell its story.
