Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

A Chef cookbook to do something.

Quick Start

To write out a JSON file from node attributes:

poise_file '/etc/myapp.json' do
  content node['myapp']
end

To update a file in place:

poise_file '/etc/hosts' do
  content 'otherhostname'
  pattern 'myhostname'
  pattern_location :replace
end

Resources

poise_file

The poise_file resource extends the core file resource to support formats
and patterns.

Formats

If the file path ends with .json or .yaml/.yml and the content property
is a Hash or Array object, it will be automatically converted. You can also
explicitly set the format property to :json or :yaml to force formatting.

Patterns

Using replacement patterns allows editing files in-place in a structured manner.
This is similar to the FileEdit API or line cookbook/resource. The pattern
property takes a RegExp object or string pattern to match against. The value of
pattern_location controls how the content gets used relative to the pattern.

  • :replacecontent replaces the matching section. If the pattern does not match, the content is not changed.
  • :replace_or_addcontent replaces the matching section. If the pattern does not match, the content is appended to the end of the file.
  • :beforecontent is inserted immediately before the matching section. If the pattern does not match, the content is not changed.
  • :aftercontent is inserted immediately after the matching section. If the pattern does not match, the content is not changed.

You can also pass a Proc to perform arbitrary manipulations:

poise_file '/etc/myapp.conf' do
  pattern proc {|existing_content| existing_content.tr('a-z', 'n-za-m') }
end

If you have an in-place editing scenario not handled by these operations, please
let me know by filing an issue.

Actions

All actions are the same as the core file resource.

Properties

  • format – File serialization format. One of :text, :json, or :yaml. (default: auto-detect)
  • pattern – Regular expression pattern or object to search for.
  • pattern_location – Mode to use for the pattern replacement. One of :replace, :replace_or_add, :before, :after. (default: :replace_or_add)

All other properties as the same as the core file resource.
