Problem with regexp?

ruby-talk
1

Hello,

I am trying to replace some old Perl scripts with Ruby, however

i get stuck with this line

if line =~/($time)/ && line =~/(xxx)/

<<
$time is a global variable containing the current day/month, but it
wont match!
what am i doing wrong?

I am new to Ruby, so please dont be offended.

in Ruby $.. wont reference a variable like in perl, use #{...}

if line =~ /#{time}/ && line =~ /(xxx)/ ....

in case of /#{(time)}/ regexp will be compiled each time...

so you may consider:

r = /#{time}/ , or:
r = Regexp.new(time)

....
probably some loop
....

if line =~ r && ...

You probably want

if line =~ /#{$time}/ and line =~ /#{xxx}/

(assuming there is a variable called xxx).
