PyCharm 2017.3 Help

Puppet

Prerequisites

Before you start working with Puppet, make sure that the Puppet Support plugin is enabled. The plugin is bundled with PyCharm and is activated by default. If the plugin is not activated, enable it on the Plugins settings page of the Settings / Preferences Dialog as described in Enabling and Disabling Plugins.

Also, puppet gem should be installed on your Ruby SDK.

Puppet support

Puppet files are marked with icon puppet.

Puppet support in PyCharm includes:

  • Compliance with the Puppet Style Guide.
  • Syntax and error highlighting.
  • Ability to rename Puppet elements.
  • Code completion in *.pp files.
  • Configuring code style for Puppet files.
  • Structure view:
    puppet structure view
  • Code completion:
    puppet completing keywords

    Moreover, with the dependencies installed, navigation and completion for each module work in strict accordance with the dependencies. For example, if you are editing a module depending on puppetlabs-apache, then you see apache in code completion:

    puppet completion
  • Navigation to a class definition, symbol, class or a usage is available:
    rm puppet goto symbol
  • Future parser.
  • Support for the EPP template language.
    • PyCharm correctly identifies the epp files, recognizes the native EPP syntax and auto-completes expressions and parameter tags:
      rm puppet epp completion

      Moreover, PyCharm allows you to navigate between a manifest and a template called.

    • Rename refactoring is available for the variables and parameters in the epp files:
      rm puppet epp rename
    • Finding usages is available for template files (Alt+F7.)

    For more information, see the blog post here.

Creating a Puppet module

The project is created in the specified location. So doing, the created project features the structure of a Puppet module. Refer the Puppet documentation for details.

puppet project created

Installing dependencies

There is an action in the Project tool window that enables installing dependencies into a Puppet module:

puppet install dependencies

Puppet modules recognize dependencies from 3 different sources:

  1. If the file .fixtures.yml exists in a Puppet module, then the dependencies are installed into the directory spec/fixtures/modules, no other sources being checked.
  2. If a Puppetfile exists in a Puppet module, then the dependencies are installed using librarian-puppet into .dependencies directory. If a Puppetfile exists, librarian-puppet ignores dependencies specified in metadata.json.
  3. If a metadata.json file exists in a Puppet module, then the dependencies are installed using librarian-puppet into .dependencies directory.

Typical workflow

Here’s how it works...

To work with a Puppet project, follow these general steps:

  1. Open or create a Puppet module.
  2. If installing dependencies from the files Puppetfile or metadata.json, make sure that the gem librarian-puppet is installed. If the gem is not yet installed, PyCharm notifies you about the missing gem and suggests to install it:
    puppet install gem

    (If the dependencies are installed from .fixtures.yml file, this gem is not required, and no notification will be shown.)

    PyCharm can find all modules/environments in a project automatically, based on dependencies files, and updates the project structure accordingly, if anything has changed. Even if PyCharm fails to update your project structure after installing additional modules into the project using the terminal, you can manually rescan the directory for modules or environments by using Scan for modules and environments action on the context menu.

  3. Having placed the dependencies in the file .fixtures.yml, Puppetfile or metadata.json, right-click the Project Tool Window, and then choose Install dependencies for module <module name> on the context menu.

    So doing, the dependencies are taken from the files .fixtures.yml, Puppetfile or metadata.json, located in the project root. The folder .dependencies (in case of creating dependencies from Puppetfile or metadata.json) or spec/fixtures/modules/ (in case of creating dependencies from .fixtures.yml) is created under the project root, if it didn't exist before.

    puppet install dependencies1

    If you want to add more dependencies, invoke this command again.
