Opens a file or text in the user's preferred editor.

TTY::Editor provides independent component for TTY toolkit.


Add this line to your application's Gemfile:

gem 'tty-editor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install tty-editor


To edit a file in default editor:'hello.rb')

To edit content in a default editor: "some text")

You can also set your preferred editor command:'hello.rb', command: :vim)

Also, the VISUAL or EDITOR shell environment variables take precedence when auto detecting available editors.

To open a file at a path pass it as a first argument:'../')

When editor successfully opens file or content then true is returned.

If the editor cannot be opened, a TTY::Editor::CommandInvocation error is raised.

In order to open text content inside an editor do: 'text')

You can also provide filename that will be created with specified content before editor is opened:'new.rb', content: 'text')

If you open a filename with already existing content then new content gets appended at the end of the file.


Use :env key to forward environment variables to the editor.'hello.rb', env: {"FOO" => "bar"})


You can force to always use a specific editor by passing :command option:'hello.rb', command: :vim)

To specify more than one command, and hence give a user a choice do:'hello.rb') do |editor|
  editor.command :vim, :emacs
