This works (not using an RE): p1 = $analysis.search("the", '1.0', stopindex='end') I want to use a regular expression in the search: p1 = $analysis.search("[a-z][A-Z]", '1.0', stopindex='end', regexp='True') but that fails "in `search': wrong number of arguments (4 for 2..3)" The equivalent line that works fine in Python/TkText is: p1 = st.search("[a-z][A-Z]", '1.0', stopindex=END, regexp=True) My question: how do I specify I am using a regular expression when searching a Ruby TkText box. Thanks.

I haven't worked with Tk yet, but taking a look at the docs, http://www.ruby-doc.org/stdlib-2.1.2/libdoc/tk/rdo..., I think you should just let ruby handle whatever you throw at it. We can use the class or kind_of? method in ruby to check the type of an object. Try > $analysis.search(/my_regexp/, '1.0', 'end') Search seems to use String#index, which accepts both Strings and Regexps. Regexp are written betweeen slashes in ruby. http://www.ruby-doc.org/core-2.1.1/Regexp.html
