This method returns an undefined value.

Initialize puppet’s settings. This is intended only for use by external tools that are not

to initialize state so that a Face may be used programatically, rather than as a stand-alone
command-line tool.

Parameters:

    the command line arguments to use for initialization

  #
  # I'd like to see about getting rid of the concept of "run_mode" entirely, but there are just too many places in

.version ⇒ String

version is a public API method intended to always provide a fast and lightweight way to determine the version of Puppet.

The intent is that software external to Puppet be able to determine the Puppet version with no side-effects. The expected use is:

require 'puppet/version'
version = Puppet.version

This function has the following ordering precedence. This precedence list is designed to facilitate automated packaging tasks by simply writing to the VERSION file in the same directory as this source file.

1. If a version has been explicitly assigned using the Puppet.version=
   method, return that version.
2. If there is a VERSION file, read the contents, trim any
   trailing whitespace, and return that version string.
3. Return the value of the Puppet::PUPPETVERSION constant hard-coded into
   the source code.

If there is no VERSION file, the method must return the version string of the nearest parent version that is an officially released version. That is to say, if a branch named 3.1.x contains 25 patches on top of the most recent official release of 3.1.1, then the version method must return the string “3.1.1” if no “VERSION” file is present.

By design the version identifier is not intended to vary during the life a process. There is no guarantee provided that writing to the VERSION file while a Puppet process is running will cause the version string to be updated. On the contrary, the contents of the VERSION are cached to reduce filesystem accesses.

The VERSION file is intended to be used by package maintainers who may be applying patches or otherwise changing the software version in a manner that warrants a different software version identifier. The VERSION file is intended to be managed and owned by the release process and packaging related tasks, and as such should not reside in version control. The PUPPETVERSION constant is intended to be version controlled in history.

Ideally, this behavior will allow package maintainers to precisely specify the version of the software they’re packaging as in the following example:

$ git describe --match "3.0.*" > lib/puppet/VERSION
$ ruby -r puppet -e 'puts Puppet.version'
3.0.1-260-g9ca4e54

Returns:

  • (String) —

    containing the puppet version, e.g. “3.0.1”
