This script converts Base16 templates written using the old Embedded Ruby syntax to the new Mustache syntax.
Just run the script with the path to the template you want to convert:
base16-template-converter.sh template.erb
A new, converted file is output in the same directory: template.mustache
This script uses sed to modify the text in the file, and specifically
requires the GNU version of sed.
If you are on macOS, you can install GNU sed through Homebrew:
brew install gnu-sed --with-default-names
Note: the --with-default-names option will cause gnu-sed to be used instead
of the built-in sed.
