Reporting Bugs
Bugs are tracked as GitHub issues. After you've determined which repository your bug is related to, create an issue on that repository and provide the following information by filling in the template.
Explain the problem and include additional details to help maintainers reproduce the problem:
Use a clear and descriptive title for the issue to identify the problem.
Describe the exact steps which reproduce the problem in as many details as possible. For example, start by explaining how you started Atom, e.g. which command exactly you used in the terminal, or how you started Atom otherwise. When listing steps, don't just say what you did, but explain how you did it. For example, if you moved the cursor to the end of a line, explain if you used the mouse, or a keyboard shortcut or an Atom command, and if so which one?
Provide specific examples to demonstrate the steps. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets in the issue, use Markdown code blocks.
Describe the behavior you observed after following the steps and point out what exactly is the problem with that behavior.
Explain which behavior you expected to see instead and why. Include screenshots and animated GIFs which show you following the described steps and clearly demonstrate the problem. If you use the keyboard while following the steps, record the GIF with the Keybinding Resolver shown. You can use this tool to record GIFs on macOS and Windows, and this tool or this tool on Linux.
If you're reporting that Atom crashed, include a crash report with a stack trace from the operating system. On macOS, the crash report will be available in Console.app under "Diagnostic and usage information" > "User diagnostic reports". Include the crash report in the issue in a code block, a file attachment, or put it in a gist and provide link to that gist.
If the problem is related to performance or memory, include a CPU profile capture with your report.
If Chrome's developer tools pane is shown without you triggering it, that normally means that you have a syntax error in one of your themes or in your styles.less. Try running in Safe Mode and using a different theme or comment out the contents of your styles.less to see if that fixes the problem.
If the problem wasn't triggered by a specific action, describe what you were doing before the problem happened and share more information using the guidelines below.
Suggesting Enhancements
Enhancement suggestions are tracked as GitHub issues. After you've determined which repository your enhancement suggestion is related to, create an issue on that repository and provide the following information:
Use a clear and descriptive title for the issue to identify the suggestion.
Provide a step-by-step description of the suggested enhancement in as many details as possible.
Provide specific examples to demonstrate the steps. Include copy/pasteable snippets which you use in those examples, as Markdown code blocks.
Describe the current behavior and explain which behavior you expected to see instead and why.
Include screenshots and animated GIFs which help you demonstrate the steps or point out the part of Atom which the suggestion is related to. You can use this tool to record GIFs on macOS and Windows, and this tool or this tool on Linux.
Explain why this enhancement would be useful to most Atom users and isn't something that can or should be implemented as a community package.
List some other text editors or applications where this enhancement exists.
Specify which version of Atom you're using. You can get the exact version by running atom -v in your terminal, or by starting Atom and running the Application: About command from the Command Palette.
Specify the name and version of the OS you're using.
