PowerShell 7 Profile Code for macOS

Microsoft.PowerShell_profile.ps1

# Apply this code to the path pointed to by the $PROFILE variable.

# Introduction
# This code includes asdf and oh-my-posh support in addition to brew.

# Requirements
# You must have the latest version of the PSReadLine module installed. Use the Install-Module -Name PSReadLine -AllowClobber -Force command.
# Also, you need to go to Nerd Font (https://www.nerdfonts.com/) and change the font to display the oh-my-posh prompt normally.

# Troubleshooting
# If it says that brew-related programs cannot be found, check if the brew path is registered in /etc/paths.d.
