Terminal of Choice: iTerm2

#productivity #codenewbie #beginners #javascript

One of the critical tools or piece of software in a developers life is the terminal or command prompt. If you are on Windows, you probably use cmd or PowerShell. If you are on Linux, you have the choice of a plethora of shells. It is the same with Mac.

I have been a Mac user for about 12 years now. It gives me the power of Linux paired with the friendliness of Windows. I would say it is a happy middle for me. It's not perfect, but it does the job reasonably well!

The terminal shipped with Mac comes with bash shell by default. If you are using Catalina or above, it has been switched to zsh by default. I will deep dive into my shell customization in another post.

Background

I started coding professionally around 2008. Coding for personal projects began in early 2004. So it's been a 16-year journey and counting. Here are a few terminal replacements I have used in the past few years:

Cmder: To date, my favorite terminal on Windows.
Hyper: It is a beautiful and extensible command-line interface built on open web standards. JavaScript developers will feel right at home.
iTerm2: Finally settled on iTerm 2.

I've been with iTerm2 for the last five years. I'm absolutely in love ❤️ with it because:

Highly configurable and multi-profile support
Split Panes
Autocomplete
Paste History
Jump to Window shortcuts
Inline Images and a Password Manager!
Free 💰

Downloads

You can get iTerm2 here. Keep in mind that it is only available for Mac.
Powerline Patched fonts are available here
Cobalt2 Color Scheme is available here
Direct link to my profile JSON is here

My Setup

Now comes the important part, my setup of iTerm2. I am going to share my extensions and settings for the terminal. You can use them; as you feel like. Below is how my terminal looks like:

Sync your iTerm2 preferences across multiple systems. Go to Preference. Select General > Preferences and check the box for Load preferences from a custom folder or URL. You can use a service like Dropbox or Google Drive.
To make the title bar match the rest of the color scheme, select Appearance > General > Theme > Minimal.
To have an unlimited amount of scroll back available in the terminal, select Profiles > Terminal > Scrollback Buffer and check Unlimited scrollback. I will attach my profile with this post so you can import it directly.

I make use of ligatures and anti-aliasing for my text. For fonts, I use powerline patched fonts, specifically Inconsolata. Download link above.

For colors, I use cobalt2. It is a theme created by Wes Bos. Download link above.

Here is my iTerm2 profile I promised. You might have to change the Working Directory. Direct link to my profile JSON is here. I keep it up to date. Happy Coding 👨🏼‍💻
