As software developers we are paid to solve problems, writing code is the mean to which we do it. If we can spend less time in the act of writing and more in the act of solving we'll deliver more value to our users, clients, or employer.
Snippets are a way to have your text editor or IDE do the typing for you. Using a predefined key phrase you can print the scaffold for functions or entire classes, then fill it up with your content.
Here's how snippets work in Xcode:
And here's how the UtilSnip Vim plugin provides snippets:
Like investing in your terminal setup configuring things such as aliases and scripts, having a wide array of snippets at your disposals is a great way to improve your productivity as a software developer.
A single snippet might not save you much typing, but as you add more and more their contribution becomes relevant. All these micro optimization compound over time.
Snippets, aliases, automation, touch typing, these are all productivity tactics aimed at removing friction between your mind thinking something and materializing it.
Once you become aware of the value of snippets you'll start seeing many occasions to create them.
- Language constructs like
if ... else ...or
guard let ... else ...
- Mundane setup code specific to a framework or library
- Test scaffolds
Today when writing code keep an eye out for things you find yourself writing over and over again. Try make a snippet for them and see the difference.
This article from NSHipster shows how to use snippets in Xcode. If alongside Xcode you also use a text editor here's how to configure snippets in:
Online you can find snippets library, like this one for Swift. They are great to take inspiration from, but I would recommend you configure your own snippets one at a time.
By working on setting up your own development environment you'll master it faster and really customize it to your very own needs, something copying someone else's configuration will never do.
Try spending a few days configuring and using your snippets and you'll see what a difference they make by removing the tedious task of writing scaffolding code.
If this post helped you getting started with snippets I'd love to hear about your experience. Or maybe you already use snippets? Then, what are your favourites? What do you use to store them?
