wtf is atom-lint?

Atom-Lint is a plugin for the Atom text editor that automatically checks your code for errors and style problems as you write. When you open or save a file, it runs the appropriate linting tool for that language and displays any issues directly in your editor, you don't have to switch to a terminal or separate tool to see what's wrong with your code. The plugin works by integrating popular open-source linting tools for different programming languages. It supports Ruby (RuboCop), Python (flake8), JavaScript (JSHint), CoffeeScript (CoffeeLint), Go, CSS, SCSS, Haskell, Puppet, shell scripts, Rust, and C/C++. When you save your file, it quietly runs the linter in the background and marks any violations with arrows in the editor's margin. Hover your cursor over a mark to see the specific problem and what rule was violated. This is particularly useful for developers who want immediate feedback on code quality without breaking their workflow. Instead of writing code, switching windows to run a linter, and then switching back, you get inline annotations that respect your editor's color theme. You can also navigate between violations using keyboard shortcuts, jumping from one issue to the next without manually scanning the file. The plugin is configurable, you can point it to custom linter installations, ignore certain files or directories, and customize keyboard shortcuts. For example, if you use a tool like rbenv to manage Ruby versions, you can tell Atom-Lint where to find your version-specific linter executable. The README notes the project is in beta, so it's still being developed, but it already covers most common programming languages.
