Using wildcards in gsub

I would like to do something like this:

"String with text and $abc$ and $def$ and so on... ".gsub("$*$", "replaceText")

which results in

"String with text and replaceText and replaceText and so on... "

But I have no idea how wildcards like * work here.

Just out of curiosity: whether one has more delimiters (not the dollar sign only,) she might use back-references:

str = "String with text and $abc$ and *def* and so on... "
str.gsub(/(?<delim>[$*]).*?\k<delim>/, "replaceText")
#⇒ "String with text and replaceText and replaceText and so on... "

Note that inside [] there is no need to escape $ (* neither.)

"String with text and $abc$ and $def$ and so on... ".gsub(/\$\w+\$/, "replaceText")

Try \$\w+\$ in http://rubular.com/

You can use regex for this purpose

"String with text and $abc$ and $def$ and so on... ".gsub(/\$\w+\$/, "replaceText")
#=> "String with text and replaceText and replaceText and so on... "

Remember you will need to escape $
