PowerShell with oh-my-posh

2024-11-16T00:00:00+00:00

Why, You Ask?

I use PowerShell on Fedora because I like having the same shell across workstations, VMs, dev containers, and Windows. oh-my-posh gives that shell a useful and consistent prompt.

Here is how I set it up with Cascadia Code Nerd Font and KDE Konsole.

Oh and guess what: This all works on Windows using Windows Terminal, too.

Step 1: Install oh-my-posh

First, we need to install oh-my-posh. It's as easy as running this command:

curl -s https://ohmyposh.dev/install.sh | bash

This script downloads the latest version of oh-my-posh and installs it. Feel free to inspect the script if you're cautious. If you're running Windows the installation is slightly different, but I guess you figure this out.

Step 2: Install Cascadia Code Nerd Font

oh-my-posh relies on a Nerd Font for its icons and styling. I chose Cascadia Code Nerd Mono because it's clean and works beautifully across different environments.

oh-my-posh font install

Set the Font in KDE Konsole:

Open Konsole.
Go to Settings > Edit Current Profile > Appearance.
Click Edit Font and select Cascadia Code Nerd Mono.

Set the Font in Windows Terminal:

Open Settings
Navigate to Font and choose Cascadia Code Nerd Mono.

Step 3: Configure PowerShell

To load oh-my-posh in PowerShell, edit your $PROFILE file.

code $PROFILE

Add the following lines to load oh-my-posh with your configuration:

oh-my-posh init pwsh --config "/path/to/oh-my-posh.json" | Invoke-Expression
clear

This initializes oh-my-posh with your chosen theme and clears the screen for a clean start.

Step 4: My oh-my-posh configuration

Here's my oh-my-posh config file. It's simple but does the job perfectly:

{
  "$schema": "https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json",
  "blocks": [
    {
      "type": "prompt",
      "alignment": "left",
      "segments": [
        {
          "properties": {
            "cache_duration": "none",
            "style": "full"
          },
          "template": "{{ .Path }} ",
          "foreground": "#77E4F7",
          "type": "path",
          "style": "plain"
        },
        {
          "properties": {
            "cache_duration": "none"
          },
          "template": "{{ .HEAD }} ",
          "foreground": "#FFE700",
          "type": "git",
          "style": "plain"
        },
        {
          "properties": {
            "cache_duration": "none"
          },
          "template": "$ ",
          "foreground": "#43D426",
          "type": "text",
          "style": "plain"
        }
      ]
    }
  ],
  "version": 3
}

Path Segment: Displays the current directory in a bright cyan.
Git Segment: Shows the current Git branch in yellow, if applicable.
Prompt Character: Displays a green $, keeping it clean and minimal.

Step 5: (optional) Create a New Profile for PowerShell in Konsole

Let's set up a dedicated profile for PowerShell in Konsole:

Duplicate an Existing Profile:

In Konsole, go to Settings > Manage Profiles.
Select your default profile and click Duplicate.

Configure the PowerShell Profile:

Rename it to PowerShell.
Set the command to pwsh.
Under Appearance, set the font to Cascadia Code Nerd Mono.
Save your changes.
Set it as default (optional)

Summary

With oh-my-posh, Cascadia Code Nerd Font, and a dedicated profile in KDE Konsole, my PowerShell setup is consistent, stylish, and super effective. Whether I'm on Fedora, a VM, or a devcontainer, my terminal always feels like home.

If you're a PowerShell fan like me, give this setup a try. Trust me, your terminal (and your productivity) will thank you.
