For sure there are endlessly many ways in which we could make Isabelle and Sledgehammer more user friendly. In Qt/C++, we had a "stripWhiteSpace" function that would do the trick. But string manipulation in ML is like pulling teeth. If you happen to know which function I can call, I'll gladly change the code.</span></div></blockquote></div><br class=""></div></body></html>
