Question

I am no expert with Perl and regex. So here is my question.

How would I write a regex for matching all words in a string to the right of a specified character and retrieve each word separately in Perl?

I don’t understand how I could match unspecified number of words and then most importantly retrieve it one at a time? If that is not possible what is my best bet in Perl to get this done?

E.G.: I have a C assignment like b=var1+var2. I want to be able to extract var1 and var2 if it exists. The important thing is I do not want to match a specific var1 and var2, but any variable after the assignment operator.

Thanks for the help!

\G/pos may be useful.

$_ = 'b=var1+var2';
# force further /g matches to start after the first '='
/=/g;

while (/(\w+)/g) {
    print "$1\n";
}

# prints
# var1
# var2
