add in readline support to ruby about pdk

[DavidS]

1. the bundled ruby is the AIO puppet agent ruby, I would not be surprised if that doesn't have readline
2. what's your usecase?

It doesn't appear to have readline support compiled in.

/opt/puppetlabs/pdk/private/ruby/2.1.9/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in require': cannot load such file -- readline (LoadError)`

I am trying to install the puppet debugger gem which requires readline support. The puppet-agent ruby has readline built in and works just fine. So the pdk ruby is different.

[DavidS]

You are totally right. Investigating this uncovered a few more components that are missing from the pdk packaging. We'll aim to include that in our next release after puppetconf.

I've created https://tickets.puppetlabs.com/browse/PDK-576 to track that.

Meanwhile you could use the pdk gem (instead of the native packaging) and use your system ruby to host it. I haven't had issues with Debian's 2.3 ruby from testing on my workstation for example.

I can't add puppet-debugger in the Gemfile until this is fixed. Responding to earlier private tweet

Another related problem I've stumbled over while playing around with this, is the fact that the vendored rgen in the vendored puppet in puppet-retrospec causes paths with more than 256 characters, which breaks the package build.

This has been fixed in 1.2.1 via puppetlabs/pdk-vanagon@e800c34
