Appendix
bundle init
Generates a Gemfile into the current working directory
This reference was automatically generated from Bundler version 4.0.18.
bundle init [--gemspec=FILE]Description
Init generates a default Gemfile(5) in the current working directory. When
adding a Gemfile(5) to a gem with a gemspec, the --gemspec option will
automatically add each dependency listed in the gemspec file to the newly
created Gemfile(5).
Options
--gemspec=GEMSPEC- Use the specified .gemspec to create the
Gemfile(5) --gemfile=GEMFILE- Use the specified name for the gemfile instead of
Gemfile
Files
Included in the default Gemfile(5)
generated is the line # frozen_string_literal: true. This is a magic comment
supported for the first time in Ruby 2.3. The presence of this line
results in all string literals in the file being implicitly frozen.
