I have a string and I need to check whether the last character of that string is *, and if it is, I need to remove it.
if stringvariable.include? "*" newstring = stringvariable.gsub(/[*]/, '') end The above does not search if the '*' symbol is the LAST character of the string.
How do i check if the last character is '*'?
Thanks for any suggestion

The chop method is used to remove the last character of a string in Ruby. If the string ends with \r\n , it will remove both the separators. If an empty string calls this method, then an empty string is returned. We can call the chop method on a string twice.
The easiest way is to use the built-in substring() method of the String class. In order to remove the last character of a given String, we have to use two parameters: 0 as the starting index, and the index of the penultimate character.
replace() method to replace the last character in a string, e.g. const replaced = str. replace(/. $/, 'replacement'); . The replace method will return a new string with the last character replaced by the provided replacement.
In double quoted strings, you can write escape sequences and Ruby will output their translated meaning. A \n becomes a newline. In single quoted strings however, escape sequences are escaped and return their literal definition. A \n remains a \n .
Use the $ anchor to only match the end of line:
"sample*".gsub(/\*$/, '') If there's the possibility of there being more than one * on the end of the string (and you want to replace them all) use:
"sample**".gsub(/\*+$/, '') If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
