# frozen_string_literal: false
# scanf for Ruby
#
#--
# $Release Version: 1.1.2 $
# $Revision$
# $Id$
# $Author$
#++
#
# == Description
#
# scanf is an implementation of the C function scanf(3), modified as necessary
# for Ruby compatibility.
#
# The methods provided are String#scanf, IO#scanf, and
# Kernel#scanf. Kernel#scanf is a wrapper around STDIN.scanf. IO#scanf
# can be used on any IO stream, including file handles and sockets.
# scanf can be called either with or without a block.
#
# Scanf scans an input string or stream according to a <b>format</b>, as
# described below in Conversions, and returns an array of matches between
# the format and the input. The format is defined in a string, and is
# similar (though not identical) to the formats used in Kernel#printf and
# Kernel#sprintf.
#
# The format may contain <b>conversion specifiers</b>, which tell scanf
# what form (type) each particular matched substring should be converted
# to (e.g., decimal integer, floating point number, literal string,
# etc.) The matches and conversions take place from left to right, and
# the conversions themselves are returned as an array.
#
# The format string may also contain characters other than those in the
# conversion specifiers. Whitespace (blanks, tabs, or newlines) in the
# format string matches any amount of whitespace, including none, in
# the input. Everything else matches only itself.
#
# Scanning stops, and scanf returns, when any input character fails to
# match the specifications in the format string, or when input is
# exhausted, or when everything in the format string has been
# matched. All matches found up to the stopping point are returned in
# the return array (or yielded to the block, if a block was given).
#
#
# == Basic usage
#
# require 'scanf'
#
# # String#scanf and IO#scanf take a single argument, the format string
# array = a_string.scanf("%d%s")
# array = an_io.scanf("%d%s")
#
# # Kernel#scanf reads from STDIN
# array = scanf("%d%s")
#
# == Block usage
#
# When called with a block, scanf keeps scanning the input, cycling back
# to the beginning of the format string, and yields a new array of
# conversions to the block every time the format string is matched
# (including partial matches, but not including complete failures). The
# actual return value of scanf when called with a block is an array
# containing the results of all the executions of the block.
#
# str = "123 abc 456 def 789 ghi"
# str.scanf("%d%s") { |num,str| [ num * 2, str.upcase ] }
# # => [[246, "ABC"], [912, "DEF"], [1578, "GHI"]]
#
# == Conversions
#
# The single argument to scanf is a format string, which generally
# includes one or more conversion specifiers. Conversion specifiers
# begin with the percent character ('%') and include information about
# what scanf should next scan for (string, decimal number, single
# character, etc.).
#
# There may be an optional maximum field width, expressed as a decimal
# integer, between the % and the conversion. If no width is given, a
# default of `infinity' is used (with the exception of the %c specifier;
# see below). Otherwise, given a field width of <em>n</em> for a given
# conversion, at most <em>n</em> characters are scanned in processing
# that conversion. Before conversion begins, most conversions skip
# whitespace in the input string; this whitespace is not counted
# against the field width.
#
# The following conversions are available.
#
# [%]
# Matches a literal `%'. That is, `%%' in the format string matches a
# single input `%' character. No conversion is done, and the resulting
# '%' is not included in the return array.
#
# [d]
# Matches an optionally signed decimal integer.
#
# [u]
# Same as d.
#
# [i]
# Matches an optionally signed integer. The integer is read in base
# 16 if it begins with `0x' or `0X', in base 8 if it begins with `0',
# and in base 10 other- wise. Only characters that correspond to the
# base are recognized.
#
# [o]
# Matches an optionally signed octal integer.
#
# [x, X]
# Matches an optionally signed hexadecimal integer,
#
# [a, e, f, g, A, E, F, G]
# Matches an optionally signed floating-point number.
#
# [s]
# Matches a sequence of non-white-space character. The input string stops at
# whitespace or at the maximum field width, whichever occurs first.
#
# [c]
# Matches a single character, or a sequence of <em>n</em> characters if a
# field width of <em>n</em> is specified. The usual skip of leading white
# space is suppressed. To skip whitespace first, use an explicit space in
# the format.
#
# [[]
# Matches a nonempty sequence of characters from the specified set
# of accepted characters. The usual skip of leading whitespace is
# suppressed. This bracketed sub-expression is interpreted exactly like a
# character class in a Ruby regular expression. (In fact, it is placed as-is
# in a regular expression.) The matching against the input string ends with
# the appearance of a character not in (or, with a circumflex, in) the set,
# or when the field width runs out, whichever comes first.
#
# === Assignment suppression
#
# To require that a particular match occur, but without including the result
# in the return array, place the <b>assignment suppression flag</b>, which is
# the star character ('*'), immediately after the leading '%' of a format
# specifier (just before the field width, if any).
#
# == scanf for Ruby compared with scanf in C
#
# scanf for Ruby is based on the C function scanf(3), but with modifications,
# dictated mainly by the underlying differences between the languages.
#
# === Unimplemented flags and specifiers
#
# * The only flag implemented in scanf for Ruby is '<tt>*</tt>' (ignore
# upcoming conversion). Many of the flags available in C versions of
# scanf(3) have to do with the type of upcoming pointer arguments, and are
# meaningless in Ruby.
#
# * The <tt>n</tt> specifier (store number of characters consumed so far in
# next pointer) is not implemented.
#
# * The <tt>p</tt> specifier (match a pointer value) is not implemented.
#
# === Altered specifiers
#
# [o, u, x, X]
# In scanf for Ruby, all of these specifiers scan for an optionally signed
# integer, rather than for an unsigned integer like their C counterparts.
#
# === Return values
#
# scanf for Ruby returns an array of successful conversions, whereas
# scanf(3) returns the number of conversions successfully
# completed. (See below for more details on scanf for Ruby's return
# values.)
#
# == Return values
#
# Without a block, scanf returns an array containing all the conversions
# it has found. If none are found, scanf will return an empty array. An
# unsuccessful match is never ignored, but rather always signals the end
# of the scanning operation. If the first unsuccessful match takes place
# after one or more successful matches have already taken place, the
# returned array will contain the results of those successful matches.
#
# With a block scanf returns a 'map'-like array of transformations from
# the block -- that is, an array reflecting what the block did with each
# yielded result from the iterative scanf operation. (See "Block
# usage", above.)
#
# == Current limitations and bugs
#
# When using IO#scanf under Windows, make sure you open your files in
# binary mode:
#
# File.open("filename", "rb")
#
# so that scanf can keep track of characters correctly.
#
# Support for character classes is reasonably complete (since it
# essentially piggy-backs on Ruby's regular expression handling of
# character classes), but users are advised that character class testing
# has not been exhaustive, and that they should exercise some caution
# in using any of the more complex and/or arcane character class
# idioms.

module Scanf
# :stopdoc:
# ==Technical notes
#
# ===Rationale behind scanf for Ruby
#
# The impetus for a scanf implementation in Ruby comes chiefly from the fact
# that existing pattern matching operations, such as Regexp#match and
# String#scan, return all results as strings, which have to be converted to
# integers or floats explicitly in cases where what's ultimately wanted are
# integer or float values.
#
# ===Design of scanf for Ruby
#
# scanf for Ruby is essentially a <format string>-to-<regular
# expression> converter.
#
# When scanf is called, a FormatString object is generated from the
# format string ("%d%s...") argument. The FormatString object breaks the
# format string down into atoms ("%d", "%5f", "blah", etc.), and from
# each atom it creates a FormatSpecifier object, which it
# saves.
#
# Each FormatSpecifier has a regular expression fragment and a "handler"
# associated with it. For example, the regular expression fragment
# associated with the format "%d" is "([-+]?\d+)", and the handler
# associated with it is a wrapper around String#to_i. scanf itself calls
# FormatString#match, passing in the input string. FormatString#match
# iterates through its FormatSpecifiers; for each one, it matches the
# corresponding regular expression fragment against the string. If
# there's a match, it sends the matched string to the handler associated
# with the FormatSpecifier.
#
# Thus, to follow up the "%d" example: if "123" occurs in the input
# string when a FormatSpecifier consisting of "%d" is reached, the "123"
# will be matched against "([-+]?\d+)", and the matched string will be
# rendered into an integer by a call to to_i.
#
# The rendered match is then saved to an accumulator array, and the
# input string is reduced to the post-match substring. Thus the string
# is "eaten" from the left as the FormatSpecifiers are applied in
# sequence. (This is done to a duplicate string; the original string is
# not altered.)
#
# As soon as a regular expression fragment fails to match the string, or
# when the FormatString object runs out of FormatSpecifiers, scanning
# stops and results accumulated so far are returned in an array.
