If you need to split a string to multiple lines within a Ruby script, this method will wrap it to a maximum line length (typically 80 characters)

ruby_string_splitter.rb

#!/usr/bin/env ruby

# initial_indent: the offset after the equals sign for the first line of string
# add_indent: the offset used for the rest of the lines (say you have the string within an indented method)
def code_split(orig_s, initial_indent=0, add_indent=0, max_len=80)
    # Simple chech before getting the work done
    if (add_indent + 5) > max_len
        raise "Not enough space left for lines." 
    end

    s = orig_s.clone
    sep = "-" * max_len
    out = "" << sep + "\n"
    s = s.gsub("\n", '\n').gsub("\r", '\r')
    res_space = max_len - 4
    bs = "\\"
    
    unless initial_indent.zero? || res_space - initial_indent < 0
        out << "\"#{s[0...(res_space - initial_indent)]}\" \\\n"
        s = s[(res_space - initial_indent)..-1]
    end

    until s.empty?
        line = " " * add_indent + '"'
        line << s[0...(res_space - add_indent)]
        nline = 0
        
        while line[-1] == bs
            nline += 1
            line = line[0..-2]
        end
         
        out << line << "\" \\\n"
        s = s[(res_space - add_indent - nline)..-1] || ""
    end
    
    out = out[0..-3] << "\n" + sep
    puts out
end
