You can use a bracketing operator to quote complex string.
%q{…} → for literal string (without interpolation). Similar to single quote '…'.%Q{…} → Evaluated string. Similar to double quote "…". Any variable, char escapes, Ruby code, are evaluated inside.%q or %Q. ⁖ %q(…), %q[…], %q|…|, %q^…^, ….This is useful if your string already contain quote characters. This way, you can change to a different bracket, so you don't need to do escapes in the string.
# -*- coding: utf-8 -*- # ruby # quote string that contain quote marks aa = %q{'1' "2" (3) [4] {5}} p aa # ⇒ "'1' \"2\" (3) [4] {5}"
# -*- coding: utf-8 -*- # ruby aa = 4 # quote string and also eval code inside p %Q{#{aa} and #{1+2} and more} # ⇒ "4 and 3 and more"
Like Perl, PHP, you have “heredoc” for quoting long string. Start with <<‹AAA› where ‹AAA› is a contunious random string. End with ‹AAA› on a line by itself.
# -*- coding: utf-8 -*- # ruby aa = 4 bb = <<HHHHHHH multi-line big string that may contain quote marks " " ' ' also code #{aa} HHHHHHH puts bb # multi-line big string # that may contain quote marks " " ' ' # also code 4
If you want the text to NOT be interpolated, start your quote string with single quote mark, like this:
# -*- coding: utf-8 -*- # ruby x = 4 myText1 = <<'tttt' x is #{x} tttt p myText1 # ⇒ "x is \#{x}\n"
If the delimiter string start are double quoted, it's also interpolated.
# -*- coding: utf-8 -*- # ruby x = 4 # interpolated myText3 = <<tttt x is #{x} tttt p myText3 # ⇒ "x is 4\n" # interpolated myText2 = <<"tttt" x is #{x} tttt p myText2 # ⇒ "x is 4\n"
