How to keep list of reglar expressions into array

Ruby
1

I have morethan one regular expressions
I want to keep all in array and iterate them to check my input matched
or not

reg1 = /ruby:\s*$/i
reg2 = /rails:\s*$/i

input1 = “ruby is my favorite language”

i want to iterate regexp’s array and check where input1 matching.But the
porblem is not the porper way getting regexp in loop .It’s returning
string type or else getting by adding ?-mix infront of regexp

can anybody help

try,

input1 = “Matz’s Ruby is my favorite language”
=> “Matz’s Ruby is my favorite language”

regs = [/ruby/i , /rails/i]
=> [/ruby/i, /rails/i]

regs.map do |re| re=~input1 end
=> [7, nil]

regs.group_by do |re| re=~input1 end
=> {7=>[/ruby/i], nil=>[/rails/i]}

In this case it’s easier to use one regexp:

/r(?:uby|ails):\s*$/i

input1 = “ruby is my favorite language”

Please show the code and the error.

You can do

if regexps.any? {|rx| rx =~ s}
puts “any matched”
end

r = regexps.find {|rx| rx =~ s} and
puts “#{r} matched”

puts “#{regexps.select {|rx| rx =~ s}} all matched”

Kind regards
