Now that our releases are [[https://blog.golang.org/2011/03/go-becomes-more-stable.html][more stable and less frequent]], this will be a common situation. Each of these API changes happened in a different weekly snapshot and might have been manageable on its own; together, however, they represent a significant amount of manual effort to update existing code. [[https://golang.org/cmd/fix/][Gofix]] is a new tool that reduces the amount of effort it takes to update existing code. It reads a program from a source file, looks for uses of old APIs, rewrites them to use the current API, and writes the program back to the file. Not all API changes preserve all the functionality of an old API, so gofix cannot always do a perfect job. When gofix cannot rewrite a use of an old API, it prints a warning giving the file name and line number of the use, so that a developer can examine and rewrite the code. Gofix takes care of the easy, repetitive, tedious changes, so that a developer can focus on the ones that truly merit attention. |
