Notice that the method name has changed from +String to Error. Package fmt's Print formats both Stringers and errors: +in general there is no need to implement both String and Error methods. + +Gofix can update most code. If you have split your package across many files, +it may help to use the -force=error command-line option, which forces gofix to +apply the error fix even if it is not obvious that a particular file needs it. +As always, it is a good idea to read and test the changes that gofix made +before committing them to your version control system. +</pre> + <h2 id="2011-11-01">2011-11-01</h2> <pre> |
