How to check whether a string contains a substring in Ruby?
Answer
Answer
I have a string variable with content as follows:
varMessage =
"hi/thsid/sdfhsjdf/dfjsd/sdjfsdn\n"
"/my/name/is/balaji.so\n"
"call::myFunction(int const&)\n"
"void::secondFunction(char const&)\n"
.
.
.
"this/is/last/line/liobrary.so"
in above string i have to find a sub string i.e.
"hi/thsid/sdfhsjdf/dfjsd/sdjfsdn\n"
"/my/name/is/balaji.so\n"
"call::myFunction(int const&)\n"
How can I find it? I just need to determine whether the substring is present or not.
Answer
You can use the include? method:
my_string = "abcdefg"
if my_string.include? "cde"
puts "String includes 'cde'"
end
