How to Apply Snippets to Each Line in VSCode: A Step-by-Step Guide

When working on multiple lines of code in Visual Studio Code (VSCode), it's common to want to apply a snippet—perhaps a code template or a repetitive structure—to each line of your selection. Many users find that the snippet menu in VSCode doesn't function the same way that Emmet does, particularly when it comes to handling multi-line selections. This guide will walk you through how to effectively apply snippets to each line in a selection, enhancing your coding efficiency.

Understanding the Problem

Imagine you have a set of relative paths to images that you've pasted into your code. You want to quickly apply a predefined snippet to each of these lines. Unfortunately, VSCode does not automatically treat each line in a selection as an individual entry for snippets. However, with a few clever techniques, you can achieve the desired result.

Solution Overview

You can apply snippets to each line of a selection in VSCode using multi-cursor functionality. Here's how you can do it:

Step-by-Step Instructions

Add Multi-Cursors at Each Line

You can create multiple cursors on each line by using:

Ctrl + Alt + Down (to add a cursor to the line below)

Ctrl + Alt + Up (to add a cursor to the line above)

Alternative Multi-Cursor Methods

If you have fewer lines, you can also use:

Alt + Click to place a cursor manually on each line.

For selecting a larger block of lines, use:

Shift + Alt + Click to create cursors across several lines.

Select the Text of Each Line

Once the cursors are in place, make sure you highlight the text where you want the snippet to be applied.

Type the Snippet Prefix and Select Your Snippet

After selecting the desired text, type the prefix of your snippet. This will trigger the snippet menu.

Select your snippet from the suggestion list to apply it to each line.

Important Considerations

Snippet Variable Usage:

Ensure that your snippet uses the variable ${TM_SELECTED_TEXT}. This variable allows snippets to insert the currently selected text at each cursor's position, enabling you to get the desired output.

Conclusion

Applying snippets to each line in a selection in Visual Studio Code may not be straightforward, but with the right techniques, it's an achievable task. By utilizing the multi-cursor functionality effectively, you can enhance your productivity and make coding a more efficient process. Next time you need to apply a snippet to multiple lines, remember these steps, and enjoy a smoother coding experience!
