Sublime How to Run Code: Keyboard Shortcuts

Sublime Text doesn't have built-in keyboard shortcuts specifically for "running code" in the way that a dedicated IDE might. The execution of code depends entirely on the programming language and the build system you've configured. Therefore, there's no single shortcut to cover all scenarios. Instead, you define a build system for your specific language (e.g., Python, JavaScript, C ), and then use the defined shortcut to execute the code using that build system. The default shortcut is usually Ctrl B (or Cmd B on macOS), but this triggers the currently selected build system.

How Can I Quickly Execute My Code in Sublime Text?

To quickly execute your code, you need to first define a build system. This involves creating a JSON file (typically in the Packages/User directory within your Sublime Text installation) that specifies the command-line instructions to run your code. For example, a simple Python build system might look like this:

<code class="json">{
  "cmd": ["python", "-u", "$file"],
  "selector": "source.python"
}</code>

This tells Sublime Text to use the python interpreter, run the file ($file represents the currently open file), and use unbuffered output (-u). The "selector" ensures this build system only applies to Python files.

Once you've saved this JSON file (e.g., Python.sublime-build), you can select it from the "Tools" -> "Build System" menu. Then, pressing Ctrl B (or Cmd B) will execute the code using the chosen build system. For other languages, you'll need to find or create appropriate build system files, specifying the correct compiler or interpreter commands for that language. Many community-contributed build systems are available online for various languages.

What Are the Keyboard Shortcuts for Running Different Programming Languages in Sublime Text?

There isn't a separate keyboard shortcut for each language. The Ctrl B (or Cmd B) shortcut executes the currently selected build system. To run code in a different language, you must first switch to the appropriate build system for that language via the "Tools" -> "Build System" menu. You can then use Ctrl B (or Cmd B) to execute your code using the newly selected build system. For improved workflow, you can create multiple build systems and assign different shortcuts using the keybindings file (located in Packages/User/Key Bindings - User.sublime-keymap).

Is There a Way to Customize the Run Code Shortcut in Sublime Text?

Yes, you can customize the "run code" shortcut (which is actually the shortcut to trigger the currently selected build system). This is done by modifying the Key Bindings - User.sublime-keymap file. This file allows you to map keyboard shortcuts to Sublime Text commands. To change the default Ctrl B shortcut, add the following to your Key Bindings - User.sublime-keymap file:

<code class="json">{
  "cmd": ["python", "-u", "$file"],
  "selector": "source.python"
}</code>

This reassigns the "build" command (which executes the selected build system) to the Alt B shortcut. Remember to save the file, and Sublime Text will recognize the new shortcut. Be cautious when choosing a shortcut; avoid conflicts with existing Sublime Text shortcuts. You can also create custom keybindings to switch between specific build systems, streamlining your workflow even further.
