In https://github.com/leehambley/sshkit/blob/ffbce7622ae57bb960d4a75375f5afb18b9228b7/lib/sshkit/backends/printer.rb#L14

output << cmd.to_s

This line call SSHKit::Formatter::Pretty.write() with object String

If temporary comment this line
https://github.com/leehambley/sshkit/blob/ffbce7622ae57bb960d4a75375f5afb18b9228b7/lib/sshkit/formatters/pretty.rb#L10
I will get messages:

Output formatter doesn't know how to handle String

In 5 minutes I have change line to:

return if obj.respond_to?(:verbosity) && obj.verbosity < SSHKit.config.output_verbosity

And add more condition:

when ::String then original_output << obj + "\n"

It's look like what I want.

I knew that is bad idea.
What you think about this problem?

[miry]

Now the option --dry-run is not working. for me too.

Downgrading to 1.0.0 works for me. I noticed that Rubygems has 1.1.0, but the repo hasn't been updated on master?

[rosic]

I think, it would work nicely if the Printer didn't call to_s on the command and just shovel the whole command object into the output (which is the Pretty formatter expecting the command). The other formatter works well with Command as well (or simply don't care)

[leehambley]

I may have changed & broken that. I can confirm the log formatters expect
objects on Command and LogMessage (?) classes. Any thing contrary is
incorrect

Yep, it works!

[reicheltd]

same issue here. using rbenv 2.0.0p247

[jrissler]

@reicheltd confirmed w rbenv 2.0.0-p247

[laertiades]

adding
gem 'sshkit', '~> 1.0.0'
before capistrano fixed issue for me

[sanichi]

Version 1.2.0 has just been released to rubygems.org, but this issue is still present.

[leehambley]

Yes, @sanichi that's why the issue is still open… ?

[stamm]

@leehambley same error on version 1.2.0

@nikita-v has a solution #58 but I guess the commit message wasn't clear, and I don't think any tests were included.

The problem is with printer line 14:

  def execute(*args)
    command(*args).tap do |cmd|
      output << sprintf("%s\n", cmd) # Offending line, sprintf returns String, output<< expects Command
    end
  end

A quick and dirty solution is:

  def execute(*args)
    command(*args).tap do |cmd|
      output << cmd # cmd is a Command and has the `verbosity` method
    end
  end

I guess at one point in time output<< accepted Strings
