Ruby: The future of frozen string literals

What is a literal?

In programming languages, literals are textual representations of values in the source code. This is a syntactical concept.

Some examples:

7 # integer literal

require 'fileutils'

# Loop through all .jpg and .png files in the current directory
Dir.glob("{*.jpg,*.png}").each do |img|
  # Construct the output filename with .webp extension
  output_filename = "#{File.basename(img, File.extname(img))}.webp"

  # Execute ffmpeg command to convert the image
  system("ffmpeg -i '#{img}' '#{output_filename}'")
end

# In Active Record, class method scopes have to remember to return `all` otherwise they're break the call chain.
#
#   def self.some_scope = nil # Assume more complex conditions that would result in a branch that accidentally didn't return `all`.
#
#   User.some_scope.first # => raises NoMethodError `first' for NilClass
#
# Note: Active Record ensures a `scope :some_scope, -> { nil }` returns `all` via `|| all` here:
# https://github.com/rails/rails/blob/c704da66de59262f4e88824589ae4eddefb6ed4a/activerecord/lib/active_record/scoping/named.rb#L181
#
# Now, this extension allows you to mark a class method as a scope, so you don't have to remember and the code is more clearly demarcated too.
