====== Option +liberal_parsing+
Specifies the boolean or hash value that determines whether
CSV will attempt to parse input not conformant with RFC 4180,
such as double quotes in unquoted fields.
Default value:
CSV::DEFAULT_OPTIONS.fetch(:liberal_parsing) # => false
For the next two examples:
str = 'is,this "three, or four",fields'
Without +liberal_parsing+:
# Raises CSV::MalformedCSVError (Illegal quoting in str 1.)
CSV.parse_line(str)
With +liberal_parsing+:
ary = CSV.parse_line(str, liberal_parsing: true)
ary # => ["is", "this \"three", " or four\"", "fields"]
Use the +backslash_quote+ sub-option to parse values that use
a backslash to escape a double-quote character. This
causes the parser to treat <code>\"</code> as if it were
<code>""</code>.
For the next two examples:
str = 'Show,"Harry \"Handcuff\" Houdini, the one and only","Tampa Theater"'
With +liberal_parsing+, but without the +backslash_quote+ sub-option:
# Incorrect interpretation of backslash; incorrectly interprets the quoted comma as a field separator.
ary = CSV.parse_line(str, liberal_parsing: true)
ary # => ["Show", "\"Harry \\\"Handcuff\\\" Houdini", " the one and only\"", "Tampa Theater"]
puts ary[1] # => "Harry \"Handcuff\" Houdini
With +liberal_parsing+ and its +backslash_quote+ sub-option:
ary = CSV.parse_line(str, liberal_parsing: { backslash_quote: true })
ary # => ["Show", "Harry \"Handcuff\" Houdini, the one and only", "Tampa Theater"]
puts ary[1] # => Harry "Handcuff" Houdini, the one and only
