These refinements give you additional syntactic sugar to build clean and concise implementations all while using less code. toc::[] == Features Enhances the following objects: * Array * BigDecimal * DateTime * Hash * IO * Pathname * String * StringIO * Structs == Requirements . https://www.ruby-lang.org[Ruby]. . A solid understanding of link:https://www.alchemists.io/articles/ruby_refinements[Ruby refinements and lexical scope]. == Setup To install, run: [source,bash] ---- gem install refinements ---- Add the following to your Gemfile file: [source,ruby] ---- gem "refinements" ---- == Usage === Requires If all refinements are not desired, add the following to your `+Gemfile+` instead: [source,ruby] ---- gem "refinements", require: false ---- ...then require the specific refinement, as needed.

The pathname remains invalid but at least you have an instance of `Pathname`, which behaves like a _Null Object_, that can be used to construct a valid path. [source,ruby] ---- Pathname(nil) # => Pathname("") ---- ===== .home Answers user home directory. [source,ruby] ---- Pathname.home # => Pathname "/Users/bkuhlmann" ---- ===== .make_temp_dir Wraps `Dir.mktmpdir` with the following behavior (see link:https://rubyapi.org/o/Dir.mktmpdir#method-c-mktmpdir[Dir.mktmpdir] for details): * *Without Block* - Answers a newly created Pathname instance which is not automatically cleaned up. * *With Block* Yields a Pathname instance, answers result of given block, and automatically cleans up temporary directory after block exits. The following examples use truncated temporary directories for illustration purposes only. In reality, these paths will be longer depending on which operating system you are using. [source,ruby] ---- Pathname.make_temp_dir # => Pathname:/var/folders/T/temp-20200101-16940-r8 Pathname.make_temp_dir prefix: "prefix-" # => Pathname:/var/folders/T/prefix-20200101-16940-r8 Pathname.make_temp_dir suffix: "-suffix" # => Pathname:/var/folders/T/temp-20200101-16940-r8-suffix Pathname.make_temp_dir prefix: "prefix-", suffix: "-suffix" # => Pathname:/var/folders/T/prefix-20200101-16940-r8-suffix Pathname.make_temp_dir root: "/example" # => Pathname:/example/temp-20200101-16940-r8 Pathname.make_temp_dir { "I am a block result" } # => "I am a block result" Pathname.make_temp_dir { |path| path.join "sub_dir" } # => Pathname:/var/folders/T/temp-20200101-16940-r8/sub_dir ---- ===== .require_tree Requires all files in given root path and corresponding nested tree structure. All files are sorted before being required to ensure consistent behavior. Example: [source,ruby] ---- # Before Dir[File.join(__dir__, "support/shared_contexts/**/*.rb")].sort.each { |path| require path } # After Pathname.require_tree __dir__, "support/shared_contexts/**/*.rb" ---- The following are further examples of potential usage: [source,ruby] ---- # Requires all files in root directory and below. Pathname.require_tree __dir__ # Requires all files in `/test/**/*.rb` and below. Pathname.require_tree "/test" # Requires all files in RSpec shared examples directory structure.

[source,ruby] ---- Pathname.root # => Pathname "/" ---- ===== #change_dir Wraps `Dir.chdir` behavior by changing to directory of current path.

[source,ruby] ---- Pathname("input.txt").copy Pathname("output.txt") # => Pathname("input.txt") ---- ===== #delete Deletes file or directory and answers itself so it can be chained.

[source,ruby] ---- Pathname("/example").directories # => [Pathname("a"), Pathname("b")] Pathname("/example").directories "a*" # => [Pathname("a")] Pathname("/example").directories flag: File::FNM_DOTMATCH # => [Pathname(".."), Pathname(".")] ---- ===== #extensions Answers file extensions as an array. [source,ruby] ---- Pathname("example.txt.erb").extensions # => [".txt", ".erb"] ---- ===== #files Answers all files or filtered files for current path.

[source,ruby] ---- Pathname("/a/path/some/path").gsub("path", "test") # => Pathname("/a/test/some/test") Pathname("/%placeholder%/some/%placeholder%").gsub("%placeholder%", "test") # => Pathname("/test/some/test") ---- ===== #make_ancestors Ensures all ancestor directories are created for a path. [source,ruby] ---- Pathname("/one/two").make_ancestors # => Pathname("/one/two") Pathname("/one").exist? # => true Pathname("/one/two").exist? # => false ---- ===== #make_dir Provides alternative `#mkdir` behavior by always answering itself (even when directory exists) and not throwing errors when directory does exist in order to ensure the pathname can be chained. [source,ruby] ---- Pathname("/one").make_dir # => Pathname("/one") Pathname("/one").make_dir.make_dir # => Pathname("/one") ---- ===== #make_path Provides alternative `#mkpath` behavior by always answering itself (even when full path exists) and not throwing errors when directory does exist in order to ensure the pathname can be chained. [source,ruby] ---- Pathname("/one/two/three").make_path # => Pathname("/one/two/three") Pathname("/one/two/three").make_path.make_path # => Pathname("/one/two/three") ---- ===== #name Answers file name without extension. [source,ruby] ---- Pathname("example.txt").name # => Pathname("example") ---- ===== #relative_parent Answers relative path from parent directory. This is a complement to `#relative_path_from`. [source,ruby] ---- Pathname("/one/two/three").relative_parent("/one") # => Pathname "two" ---- ===== #remove_dir Provides alternative `#rmdir` behavior by always answering itself (even when full path exists) and not throwing errors when directory does exist in order to ensure the pathname can be chained.

[source,ruby] ---- Pathname("/test.txt").rewrite # => Pathname("/test.txt") Pathname("/test.txt").rewrite { |body| body.sub "[token]", "example" } # => Pathname("/test.txt") ---- ===== #touch Updates access and modification times for path. Defaults to current time. [source,ruby] ---- Pathname("example.txt").touch # => Pathname("example.txt") Pathname("example.txt").touch Time.now - 1 # => Pathname("example.txt") ---- ===== #write Writes to file and answers itself so it can be chained. See `IO.write` for details on additional options. [source,ruby] ---- Pathname("example.txt").write "test" # => Pathname("example.txt") Pathname("example.txt").write "test", offset: 1 # => Pathname("example.txt") Pathname("example.txt").write "test", mode: "a" # => Pathname("example.txt") ---- ==== String ===== #blank?
