gem 'tty-editor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install tty-editor

Usage

To edit a file in default editor:

TTY::Editor.open('hello.rb')

To edit content in a default editor:

TTY::Editor.open(content: "some text")

You can also set your preferred editor command:

TTY::Editor.open('hello.rb', command: :vim)

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

Interface

open

If you wish to open editor with no file or content do:

TTY::Editor.open

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:

TTY::Editor.open(content: 'text')

You can also provide filename that will be created with specified content before editor is opened:

TTY::Editor.open('new.rb', content: 'text')

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

:env

Use :env key to forward environment variables to the editor.

TTY::Editor.open('hello.rb', env: {"FOO" => "bar"})

:command

You can force to always use a specific editor by passing :command option:

TTY::Editor.open('hello.rb', command: :vim)
