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 supermarket mailing list.

line cookbook


Quite often, the need arises to do line editing instead of managing an entire file with a template resource. This cookbook supplies various resources that will help you do this.


Add "depends 'line'" to your cookbook's metadata.rb to gain access to the resoures.

append_if_no_line "make sure a line is in dangerfile" do
  path "/tmp/dangerfile"

replace_or_add "spread the love" do
  path "/some/file"
  pattern "Why hello there.*"
  line "Why hello there, you beautiful person, you."

delete_lines "remove hash-comments from /some/file" do
  path "/some/file"
  pattern "^#.*"

add_to_list "add entry to a list"
  path "/some/file"
  pattern "People to call: "
  delim [","]
  entry "Bobby"

delete_from_list "delete entry from a list"
  path "/some/file"
  pattern "People to call: "
  delim [","]
  entry "Bobby"


So far, the only resource implemented are


add_to_list delim must be an array of 1, 2 or 3 multi-character elements. If one delimiter is given, it is assumed that either the delimiter or the given search pattern will proceed each entry and each entry will be followed by either the delimeter or a new line character: People to call: Joe, Bobby delim [","] entry 'Karen' People to call: Joe, Bobby, Karen

  If two delimiters are given, the first is used as the list element delimiter and the second as entry delimiters:
      my @net1918 = ("", "");
  delim [", ", "\""]
  entry ""
      my @net1918 = ("", "", "");

  if three delimiters are given, the first is used as the list element delimiter, the second as the leading entry delimiter and the third as the trailing delimiter:
      multi = ([310], [818])
  delim [", ", "[", "]"]
  entry "425"
      multi = ([310], [818], [425])

delete_from_list Works exactly the same way as add_to_list, see above.

More to follow.

line Cookbook CHANGELOG

v0.6.3 (2015-10-27)

  • Fixing Ruby and Chef deprecation warnings
  • Cleaning up tests a bit
  • Adding support for source_url and issues_url
  • delete_from_list resource

v0.6.2 (2015-07-15)

  • Catch lines missed by strict patterns
  • Add rspec tests for the replace_or_add provider. The existing chefspec tests don't step into the provider code and so don't check the provider functionality.
  • Change the Gemfile to reflect the need for berkshelf 3, chefspec v4.2, rspec 3 for the tests.
  • Update provider_replace_or_add to handle cases where the pattern does not match the replacement line.
  • Fix notification problem where updated_by_last_action was set when nothing changed.

v0.6.1 (2015-02-24)

  • Adding CHANGELOG
  • Adding ChefSpec matchers
