For example I’ve got string /wiki/File:test.JPG I should check if it has one of extention "jpeg","jpg","png","gif"
Currently I’ve written that link.search(/.[j,p,g][p,i,n][e,g,f][g]?/gi) and it is works, but I’d like better regular expression.
Just write the regex as a list:
/\.(jpe?g|png|gif)$/gi(note the escaped dot (
.))EDIT: Added a
$.
