How can I change one or more line breaks to something in ruby?
article.content.gsub(/\n/, "<br />")
above code will change every 1 line break to <br />
tag, however, I want to change one or more \n to <br />
tag. In that way, continuous line breaks with empty lines will be substitued into a single <br />
tag. How can I do that?
Are you looking for this?
article.content.gsub(/\n+/, "<br />")
Note the plus sign after the \n
. That will change any sequence of one or more newlines to a single <br>
.
It also might be helpful to quickly test Ruby regular expressions against sample data using Rubular .
