# Objects of class Dir are directory streams representing | |
# directories in the underlying file system. They provide a variety | |
# of ways to list directories and their contents. See also File. | |
# | |
# The directory used in these examples contains the two regular files | |
# (<code>config.h</code> and <code>main.rb</code>), the parent | |
# directory (<code>..</code>), and the directory itself | |
# (<code>.</code>). | |
# | |
# == What's Here | |
# | |
# \Class \Dir provides methods that are useful for: | |
# | |
# - {Reading}[#class-Dir-label-Reading] | |
# - {Setting}[#class-Dir-label-Setting] | |
# - {Querying}[#class-Dir-label-Querying] | |
# - {Iterating}[#class-Dir-label-Iterating] | |
# - {Other}[#class-Dir-label-Other] | |
# | |
# === Reading | |
# | |
# - #close:: Closes the directory stream for +self+. | |
# - #pos=:: Sets the position in the directory stream for +self+. | |
# - #read:: Reads and returns the next entry in the directory stream for +self+. | |
# - #rewind:: Sets the position in the directory stream for +self+ to the first entry. | |
# - #seek:: Sets the position in the directory stream for +self+ | |
# the entry at the given offset. | |
# | |
# === Setting | |
# | |
# - ::chdir:: Changes the working directory of the current process | |
# to the given directory. | |
# - ::chroot:: Changes the file-system root for the current process | |
# to the given directory. | |
# | |
# === Querying | |
# | |
# - ::[]:: Same as ::glob without the ability to pass flags. | |
# - ::children:: Returns an array of names of the children | |
# (both files and directories) of the given directory, | |
# but not including <tt>.</tt> or <tt>..</tt>. | |
# - ::empty?:: Returns whether the given path is an empty directory. | |
# - ::entries:: Returns an array of names of the children | |
# (both files and directories) of the given directory, | |
# including <tt>.</tt> and <tt>..</tt>. | |
# - ::exist?:: Returns whether the given path is a directory. | |
# - ::getwd (aliased as #pwd):: Returns the path to the current working directory. | |
# - ::glob:: Returns an array of file paths matching the given pattern and flags. | |
# - ::home:: Returns the home directory path for a given user or the current user. | |
# - #children:: Returns an array of names of the children | |
# (both files and directories) of +self+, | |
# but not including <tt>.</tt> or <tt>..</tt>. | |
# - #fileno:: Returns the integer file descriptor for +self+. | |
# - #path (aliased as #to_path):: Returns the path used to create +self+. | |
# - #tell (aliased as #pos):: Returns the integer position | |
# in the directory stream for +self+. | |
# | |
# === Iterating | |
# | |
# - ::each_child:: Calls the given block with each entry in the given directory, | |
# but not including <tt>.</tt> or <tt>..</tt>. | |
# - ::foreach:: Calls the given block with each entryin the given directory, | |
# including <tt>.</tt> and <tt>..</tt>. | |
# - #each:: Calls the given block with each entry in +self+, | |
# including <tt>.</tt> and <tt>..</tt>. | |
# - #each_child:: Calls the given block with each entry in +self+, | |
# but not including <tt>.</tt> or <tt>..</tt>. | |
# | |
# === Other | |
# | |
# - ::mkdir:: Creates a directory at the given path, with optional permissions. | |
# - ::new:: Returns a new \Dir for the given path, with optional encoding. | |
# - ::open:: Same as ::new, but if a block is given, yields the \Dir to the block, | |
# closing it upon block exit. | |
# - ::unlink (aliased as ::delete and ::rmdir):: Removes the given directory. | |
# - #inspect:: Returns a string description of +self+. | |
class Dir | |
# Dir.open( string ) -> aDir | |
# Dir.open( string, encoding: enc ) -> aDir | |
# Dir.open( string ) {| aDir | block } -> anObject | |
# Dir.open( string, encoding: enc ) {| aDir | block } -> anObject | |
# | |
# The optional <i>encoding</i> keyword argument specifies the encoding of the directory. | |
# If not specified, the filesystem encoding is used. | |
# | |
# With no block, <code>open</code> is a synonym for Dir::new. If a | |
# block is present, it is passed <i>aDir</i> as a parameter. The | |
# directory is closed at the end of the block, and Dir::open returns | |
# the value of the block. | |

# Dir.new( string ) -> aDir | |
# Dir.new( string, encoding: enc ) -> aDir | |
# | |
# Returns a new directory object for the named directory. | |
# | |
# The optional <i>encoding</i> keyword argument specifies the encoding of the directory. | |
# If not specified, the filesystem encoding is used. | |

Primitive.dir_s_aref(args, base, sort) | |

# Dir.glob( pattern, [flags], [base: path] [, sort: true] ) -> array | |
# Dir.glob( pattern, [flags], [base: path] [, sort: true] ) { |filename| block } -> nil | |
# | |
# Expands +pattern+, which is a pattern string or an Array of pattern | |
# strings, and returns an array containing the matching filenames. | |
# If a block is given, calls the block once for each matching filename, | |
# passing the filename as a parameter to the block. | |
# | |
# The optional +base+ keyword argument specifies the base directory for | |
# interpreting relative pathnames instead of the current working directory. | |
# As the results are not prefixed with the base directory name in this | |
# case, you will need to prepend the base directory name if you want real | |
# paths. | |
# | |
# The results which matched single wildcard or character set are sorted in | |
# binary ascending order, unless false is given as the optional +sort+ | |
# keyword argument. The order of an Array of pattern strings and braces | |
# are preserved. | |
# | |
# Note that the pattern is not a regexp, it's closer to a shell glob. | |
# See File::fnmatch for the meaning of the +flags+ parameter. | |
# Case sensitivity depends on your system (File::FNM_CASEFOLD is ignored). | |
# | |
# <code>*</code>:: | |
# Matches any file. Can be restricted by other values in the glob. | |
# Equivalent to <code>/.*/mx</code> in regexp. | |
# | |
# <code>*</code>:: Matches all files | |
# <code>c*</code>:: Matches all files beginning with <code>c</code> | |
# <code>*c</code>:: Matches all files ending with <code>c</code> | |
# <code>\*c\*</code>:: Match all files that have <code>c</code> in them | |
# (including at the beginning or end). | |
# | |
# Note, this will not match Unix-like hidden files (dotfiles). In order | |
# to include those in the match results, you must use the | |
# File::FNM_DOTMATCH flag or something like <code>"{*,.*}"</code>. | |
# | |
# <code>**</code>:: | |
# Matches directories recursively if followed by <code>/</code>. If | |
# this path segment contains any other characters, it is the same as the | |
# usual <code>*</code>. | |
# | |
# <code>?</code>:: | |
# Matches any one character. Equivalent to <code>/.{1}/</code> in regexp. | |
# | |
# <code>[set]</code>:: | |
# Matches any one character in +set+. Behaves exactly like character sets | |
# in Regexp, including set negation (<code>[^a-z]</code>). | |
# | |
# <code>{p,q}</code>:: | |
# Matches either literal <code>p</code> or literal <code>q</code>. | |
# Equivalent to pattern alternation in regexp. | |
# | |
# Matching literals may be more than one character in length. More than | |
# two literals may be specified. | |
# | |
# <code>\\</code>:: | |
# Escapes the next metacharacter. | |
# | |
# Note that this means you cannot use backslash on windows as part of a | |
# glob, i.e. <code>Dir["c:\\foo*"]</code> will not work, use | |
# <code>Dir["c:/foo*"]</code> instead. | |
# | |
# Examples: | |
# | |
# Dir["config.?"] #=> ["config.h"] | |
# Dir.glob("config.?") #=> ["config.h"] | |
# Dir.glob("*.[a-z][a-z]") #=> ["main.rb"] | |
# Dir.glob("*.[^r]*") #=> ["config.h"] | |
# Dir.glob("*.{rb,h}") #=> ["main.rb", "config.h"] | |
# Dir.glob("*") #=> ["config.h", "main.rb"] | |
# Dir.glob("*", File::FNM_DOTMATCH) #=> [".", "..", "config.h", "main.rb"] | |
# Dir.glob(["*.rb", "*.h"]) #=> ["main.rb", "config.h"] | |
# | |
# Dir.glob("**/*.rb") #=> ["main.rb", | |
# # "lib/song.rb", | |
# # "lib/song/karaoke.rb"] | |
# | |
# Dir.glob("**/*.rb", base: "lib") #=> ["song.rb", | |
# # "song/karaoke.rb"] | |
# | |
# Dir.glob("**/lib") #=> ["lib"] | |
# | |
# Dir.glob("**/lib/**/*.rb") #=> ["lib/song.rb", | |
# # "lib/song/karaoke.rb"] | |
# | |
# Dir.glob("**/lib/*.rb") #=> ["lib/song.rb"] | |

# call-seq: | |
# File.fnmatch( pattern, path, [flags] ) -> (true or false) | |
# File.fnmatch?( pattern, path, [flags] ) -> (true or false) | |
# | |
# Returns true if +path+ matches against +pattern+. The pattern is not a | |
# regular expression; instead it follows rules similar to shell filename | |
# globbing. It may contain the following metacharacters: | |
# | |
# <code>*</code>:: | |
# Matches any file. Can be restricted by other values in the glob. | |
# Equivalent to <code>/.*/x</code> in regexp. | |
# | |
# <code>*</code>:: Matches all files regular files | |
# <code>c*</code>:: Matches all files beginning with <code>c</code> | |
# <code>*c</code>:: Matches all files ending with <code>c</code> | |
# <code>\*c*</code>:: Matches all files that have <code>c</code> in them | |
# (including at the beginning or end). | |
# | |
# To match hidden files (that start with a <code>.</code> set the | |
# File::FNM_DOTMATCH flag. | |
# | |
# <code>**</code>:: | |
# Matches directories recursively or files expansively. | |
# | |
# <code>?</code>:: | |
# Matches any one character. Equivalent to <code>/.{1}/</code> in regexp. | |
# | |
# <code>[set]</code>:: | |
# Matches any one character in +set+. Behaves exactly like character sets | |
# in Regexp, including set negation (<code>[^a-z]</code>). | |
# | |
# <code>\\</code>:: | |
# Escapes the next metacharacter. | |
# | |
# <code>{a,b}</code>:: | |
# Matches pattern a and pattern b if File::FNM_EXTGLOB flag is enabled. | |
# Behaves like a Regexp union (<code>(?:a|b)</code>). | |
# | |
# +flags+ is a bitwise OR of the <code>FNM_XXX</code> constants. The same | |
# glob pattern and flags are used by Dir::glob. | |
