Syntax highlighting in nano on Mac OS

install nano.sh

# Last updated March, 2022 for Apple silicon Macs
# Install Homebrew if you don't already have it: https://brew.sh

# install nano from homebrew
brew install nano nanorc

# update your nanorc file
echo 'include "/opt/homebrew/share/nanorc/*.nanorc"' >> ~/.nanorc

# close and re-open your terminal and you'll have syntax highlighting

echo 'include "/usr/local/Cellar/nano/*/share/nano/*.nanorc"' >> ~/.nanorc

Probably it would be better to use

echo 'include "'"$(brew --cellar nano)"'/*/share/nano/*.nanorc"' >> ~/.nanorc

so in such case it will use the right path depends on if mac uses Intel or Apple Silicon
