Provides a Ruby API to control Vagrant where Vagrant is installed via the Installer package on Mac OS X. Vagrant was historically available as a gem, naturally providing a Ruby API to control Vagrant in other Ruby libraries and applications. However, since version 1.1.0, Vagrant is distributed exclusively using an Installer package. To control Vagrant when it's installed this way, other Ruby libraries and applications typically need to invoke the Vagrant binary, which requires forking a new process and parsing its output using string manipulation.

# SecureDataBag / Knife Secure Bag Knife Secure Bag provides a consistent interface to DataBagItem, EncryptedDataBagItem as well as the custom created SecureDataBagItem while also providing a few extra handy features to help in your DataBag workflows. SecureDataBagItem, can not only manage your existing DataBagItems and EncryptedDataBagItems, but it also provides you with a DataBag type which enables you to selectively encrypt only some of the fields in your DataBag thus allowing you to be able to search for the remaining fields. ## Installation To build and install the plugin add it your Gemfile or run: ```shell gem install secure_data_bag ``` ## Configuration #### Knife Secure Bag Defaults for the Knife command may be provided in your _knife.rb_ file. ```ruby knife[:secure_data_bag][:encrypted_keys] = %w( password ssh_keys ssh_ids public_keys private_keys keys secret ) knife[:secure_data_bag][:secret_file] = "#{local_dir}/secret.pem" knife[:secure_data_bag][:export_root] = "#{kitchen_dir}/data_bags" knife[:secure_data_bag][:export_on_upload] = true knife[:secure_data_bag][:defaults][:secrets][:export_format] = 'plain' ``` To break this up: `knife[:secure_data_bag][:encrypted_keys] = []` When Knife Secure Bag encrypts a hash with an _encryption format_ of *nested*, it will recursively walk through the hash from the bottom up and encrypt any key found within this array. `knife[:secure_data_bag][:secret_file]` When encryption is required, the shared secret found at this location will be loaded. `knife[:secure_data_bag][:export_root]` When exporting a data\_bag\_item, files will be created in below this root directory. Typically this would be the data\_bag folder located within your kitchen. `knife[:secure_data_bag][:export_on_upload]` When a data\_bag\_item is edited using `knife secure bag edit`, it may be automatically exported to the _export\_root_. `knife[:secure_data_bag][:defaults][:secrets][:export_format]` The configuration file additionally supports the _defaults_ hash which provides default values for all _command line arguments_ that one might use. Of all of them only the _export\_format_ key is likely to be of much use. ## Examples #### Chef cookbook recipe ```ruby metadata = {} # Define the keys we wish to encrypt metadata[:encrypted_keys] = %w(encoded) # Optionally load a specific shared secret. Otherwise, the global # encrypted\_data\_bag\_secret will be automatically used. secret_key = SecureDataBagItem.load_key("/path/to/secret") # Create a hash of data to use as an exampe raw_data = { id: "item", data_bag: "data_bag", encoded: "my string", unencoded: "other string" } # Instantiate a SecureDataBagItem from a hash item = SecureDataBagItem.from_hash(data, metadata) # Or more explicitely item = SecureDataBagItem.from_hash(data, encrypted_keys: %w(encoded)) # Or load from server item = SecureDataBagItem.load("data_bag", "item") # Print the un-encrypted raw data pp item.raw_data # Print the un-encrypted `encoded` key pp item['encoded'] # Print the encrypted hash as a data_bag_item hash pp item.to_hash =begin { id: "item", data_bag: "data_bag", encoded: { encrypted_data: "encoded", cipher: aes-256-cbc, iv: 13453453dkgfefg== version: 1 } unencoded: "other string", } =end ``` ## Usage #### Knife commands Print an DataBagItem, EncryptedDataBagItem or SecureDataBagItem, auto-detecting the encryption method used as plain text. ```shell knife secure bag show -F js secrets secret_item ``` Print an DataBagItem, EncryptedDataBagItem or SecureDataBagItem, auto-detecting the encryption method used as a SecureDataBagItem in encrypted format. ```shell knife secure bag show -F js secrets secret_item --enc-format nested ``` Edit an EncryptedDataBagItem, preserve it's encryption type, and export a copy to the _data\_bag_ folder in your kitchen. ```shell knife secure bag edit secrets secret_item --export ``` ## Knife SubCommands Most of the SubCommands support the following command-line options: `--enc-format [plain,encrypted,nested]` Ensure that, when displaying or uploading the data\_bag\_item, we forcibly encrypt the data\_bag\_item using the specified format instead of preserving the existing format. In this case: - plain: refers to a DataBagItem - encrypted: refers to an EnrytpedDataBagItem - nested: refers to a SecureDataBagItem `--dec-format [plain,encrypted,nested]` Attempt to decrypt the data\_bag\_item using the given format rather than the auto-detected one. The only real reason to use this is when you wish to specifically select _plain_ as the format so as to not decrypt the item. `--enc-keys key1,key2,key3` Provide a comma delimited list of hash keys which should be encrypted when encrypting the data\_bag\_item. This list will be concatenated with any key names listed in the configuration file or which were previously encrypted. `--export` Export the data\_bag\_item to json file in either of _export-format_ or _enc-format_. `--export-format` Overrides the encryption format only for the _export_ feature. `--export-root` Root directly under which a folder should exist for each _data_bag_ into which to export _data_bag_items_ as json files. When displaying the content of the _data\_bag\_item_, an additional key of *_secure_metadata* will be added to the output which contains gem specific metadata such as the encryption formats and any encrypted keys found. This key will _not_ be saved with the item, however it may be manipulated to alter the behavior of the _edit_ or _export_ commands. #### knife secure bag show DATA_BAG ITEM This command functions just like `knife data bag show` and is used to print out the content of either a DataBagItem, EncryptedDataBagItem or SecureDataBagItem. By default, it will auto-detect the Item type, and print it's unencrypted version to the terminal. This behavior, however, may be altered using the previously mentioned command line options. #### knife secure bag open PATH This commands functions much like `knife secure bag show`, however it is designed to load a _data\_bag\_item_ from disk as opposed to loading it from Chef server. This may be of use when view the content of an exported encrypted file. #### knife secure bag edit DATA_BAG DATA_BAG_ITEM This command functions just like `knife data bag edit` and is used to edit either a DataBagItem, EncryptedDataBagItem or a SecureDataBagItem. It supports all of the same options as `knife secure bag show`. #### knife secure bag from file DATA_BAG PATH This command functions just like `knife data bag from file` and is used to upload either a DataBagItem, EncryptedDataBagItem or a SecureDataBagItem. It supports all of the same options as `knife secure bag show`. ## Recipe DSL The gem additionally provides a few Recipe DSL methods which may be useful. ```ruby load_secure_item = secure_data_bag_item( data_bag_name, data_bag_item, cache: false ) load_plain_item = data_bag_item(data_bag_name, data_bag_item) convert_plain_to_secure = secure_data_bag_item!(load_plain_item) ```

== ICU4R - ICU Unicode bindings for Ruby ICU4R is an attempt to provide better Unicode support for Ruby, where it lacks for a long time. Current code is mostly rewritten string.c from Ruby 1.8.3. ICU4R is Ruby C-extension binding for ICU library[1] and provides following classes and functionality: * UString: - String-like class with internal UTF16 storage; - UCA rules for UString comparisons (<=>, casecmp); - encoding(codepage) conversion; \ - Unicode normalization; - transliteration, also rule-based; Bunch of locale-sensitive functions: - upcase/downcase; - string collation; \ - string search; - iterators over text line/word/char/sentence breaks; \ - message formatting (number/currency/string/time); - date and number parsing. * URegexp - unicode regular expressions. * UResourceBundle - access to resource bundles, including ICU locale data. * UCalendar - date manipulation and timezone info. * UConverter - codepage conversions API * UCollator - locale-sensitive string comparison == Install and usage > ruby extconf.rb > make && make check > make install Now, in your scripts just require 'icu4r'. To create RDoc, run > sh tools/doc.sh == Requirements To build and use ICU4R you will need GCC and ICU v3.4 libraries[2]. == Differences from Ruby String and Regexp classes === UString vs String 1. UString substring/index methods use UTF16 codeunit indexes, not code points. 2. UString supports most methods from String class. Missing methods are: capitalize, capitalize!, swapcase, swapcase! %, center, ljust, rjust chomp, chomp!, chop, chop! \ count, delete, delete!, squeeze, squeeze!, tr, tr!, tr_s, tr_s! crypt, intern, sum, unpack dump, each_byte, each_line hex, oct, to_i, to_sym reverse, reverse! succ, succ!, next, next!, upto 3. Instead of String#% method, UString#format is provided. See FORMATTING for short reference. 4. UStrings can be created via String.to_u(encoding='utf8') or global u(str,[encoding='utf8']) calls. Note that +encoding+ parameter must be value of String class. 5. There's difference between character grapheme, codepoint and codeunit. See UNICODE reports for gory details, but in short: locale dependent notion of character can be presented using more than one codepoint - base letter and combining (accents) (also possible more than one!), and each codepoint can require more than one codeunit to store (for UTF8 codeunit size is 8bit, though \ some codepoints require up to 4bytes). So, UString has normalization and locale dependent break iterators. 6. Currently UString doesn't include Enumerable module. 7. UString index/[] methods which accept URegexp, throw exception if Regexp passed. 8. UString#<=>, UString#casecmp use UCA rules. === URegexp UString uses ICU regexp library. Pattern syntax is described in [./docs/UNICODE_REGEXPS] and ICU docs. There are some differences between processing in Ruby Regexp and URegexp: 1. When UString#sub, UString#gsub are called with block, special vars ($~, $&, $1, ...) aren't set, as their values are processed through deep ruby core code. Instead, block receives UMatch object, which is essentially immutable array of matching groups: "test".u.gsub(ure("(e)(.)")) do |match| \ puts match[0] # => 'es' <--> $& puts match[1] # => 'e' \ <--> $1 puts match[2] # => 's' <--> $2 end 2. In URegexp search pattern backreferences are in form \n (\1, \2, ...), in replacement string - in form $1, $2, ... NOTE: URegexp considers char to be a digit NOT ONLY ASCII (0x0030-0x0039), but any Unicode char, which has property Decimal digit number (Nd), e.g.: a = [?$, 0x1D7D9].pack("U*").u * 2 puts a.inspect_names <U000024>DOLLAR SIGN <U01D7D9>MATHEMATICAL DOUBLE-STRUCK DIGIT ONE <U000024>DOLLAR SIGN <U01D7D9>MATHEMATICAL DOUBLE-STRUCK DIGIT ONE puts "abracadabra".u.gsub(/(b)/.U, a) abbracadabbra \ 3. One can create URegexp using global Kernel#ure function, Regexp#U, Regexp#to_u, or from UString using URegexp.new, e.g: /pattern/.U =~ "string".u 4. There are differences about Regexp and URegexp multiline matching options: t = "text\ntest" # ^,$ handling : URegexp multiline <-> Ruby default t.u =~ ure('^\w+$', URegexp::MULTILINE) => #<UMatch:0xf6f7de04 @ranges=[0..3], @cg=[\u0074\u0065\u0078\u0074]> t =~ /^\w+$/ => 0 # . matches \n : URegexp DOTALL <-> /m t.u =~ ure('.+test', URegexp::DOTALL) \ => #<UMatch:0xf6fa4d88 ... t.u =~ /.+test/m 5. UMatch.range(idx) returns range for capturing group idx. This range is in codeunits. === References 1. ICU Official Homepage http://ibm.com/software/globalization/icu/ 2.

Utils for version-strings manipulation

Bindings for libfa, a library to manipulate finite automata. Automata are constructed from regular expressions, using extended POSIX syntax, and make it possible to compute interesting things like the intersection of two regular expressions (all strings matched by both), or the complement of a regular expression (all strings _not_ matched by the regular expression). It is possible to convert from regular expression (compile) to finite automaton, and from finite automaton to regular expression (as_regexp)

Most existing gems that address command execution provide a limited interface or lack notable features. In contast, Exek seeks to provide comprehensive support for all of a program's exec needs with one thoughtfully-designed library. Intended features: - A "Command" class that encapsulates argv, env, and IO options, and process state. - Easy-to-use high level interfaces with sensible defaults for running commands to completion. - Comprehensive support for low-level concerns like piping, PTYs, and file descriptor magic. - Utilities for manipulating `sh` script strings, idiomatically building argument arrays, and generating reusable interaces for common system commands. - Tracing and introspection facilities for logging and latency analysis. - Safety: does not monkeypatch external modules, encourage mixins or use eval. Attempts to guide developers away from unsafe practices like shell scripts and shell injection.

FilePermissions is a Ruby library providing an object representation of the file permission bits in POSIX systems. It can handle the generic read, write and execute permissions, as well as the setuid, setgid and sticky flags. Permission sets can be read from file system objects, parsed from typical string representations or simply defined by their numeric representation. They can then be manipulated through binary logic operators and written back to file system objects.
