Automize unix commands4/29/2023 Reload Atom to pick up your new commandĮach time you open a new Atom window, Atom loads your init script. And once that command completes, line 5 invokes the final command ( line-ending-selector:convert-to-LF).Īs you venture into defining your own composed commands, Atom’s API docs can guide you in understanding the details of each function used above as well as the many other functions available to help you customize Atom. Once that command completes, line 4 invokes the second command ( whitespace:remove-trailing-whitespace). Line 3 invokes, the first command ( whitespace:convert-all-tabs-to-spaces).In this case, it’s me:personalize-whitespace. On line 1, the second argument specifies the name of the new command.dispatch ( view, 'line-ending-selector:convert-to-LF' )įor the purposes of this example, there are two important items to note in this snippet: dispatch ( view, 'whitespace:remove-trailing-whitespace' ). dispatch ( view, 'whitespace:convert-all-tabs-to-spaces' ). add 'atom-workpace', 'me:personalize-whitespace', -> view = atom. Next, paste in the snippet below to define your new command:Ītom. Open your init scriptįirst, activate the command palette, and run the “Application: Open Your Init Script” command. Or, you could combine them into a single “composed” command. Whitespace: Removing Trailing Whitespace.You could accomplish this by running these three commands, one after another: For example, assume you want to convert tabs to spaces, trim any trailing whitespace on each line, and convert line endings from Windows-style (CRLF) to Unix-style (LF). Imagine you often encounter files where you want to change the use of whitespace. Composing a command to run other commands And while you may currently perform those actions using the menu, using the keyboard, or clicking with your mouse, they can also be triggered programatically. Whether you’re moving the cursor to the right, saving the current file, closing a tab, or pushing code to a Git repository, each action is a named command. Many of the actions that you perform in Atom are accessible as commands. By taking advantage of Atom’s hackability, you can eliminate this repetition with a custom command to perform an entire sequence of actions for you. When working with text, it’s common to find yourself performing a certain set of actions in the same order, time and time again.
