可以重构的IDE for Go：变量，函数，结构和包重命名

Question

I am interested in any IDE (or even a script) that is capable of refactoring Go source code for variable renaming. For example in Eclipse for Java, one can select a variable, an object or a class, then to rename it and it gets automatically renamed in all the files in the project. This feature is very useful if automatic string replacement may cause substring collisions.

Answer 1

If you're interested in a script, use gofmt with -r flag. Like this:

gofmt -w -r 'OldFoo -> Foo' foopackage

From the docs:

Without an explicit path, it processes the standard input. Given a file, it operates on that file; given a directory, it operates on all .go files in that directory, recursively. (Files starting with a period are ignored.) By default, gofmt prints the reformatted sources to standard output.

EDIT: Today there are better tools for that: gorename for renaming and eg for general refactoring.
