How to do a forward compatibility support for go 1.13?

[changkun]

I have upgraded my code to Go 1.13 with newly introduced errors APIs.

However, I am not able to upgrade the production environment Go version which is Go 1.11, which means I have to run Go 1.13 code on a Go 1.11 environment.

What are the way to make my builds both happy on local and production environment with a single code base?

I think that in general you will have to only use features available to Go 1.11, meaning, of course, that the new methods in the errors package would be off limits. In the mean time you could use golang.org/x/xerrors, which is a superset of the new errors package and I believe will work with 1.11.

This may not be the exact answer you're looking for, but there's a package which handles this even better than Go's builtin error package:

https://github.com/pkg/errors

Dave Cheney's package is better designed, IMO, and the explicit errors.Wrap() call is more clear than inferring it from your format string.

Use

    import errors "golang.org/x/xerrors"

this way later you only have to replace it with `import "errors"` and `errors.Errorf` with `fmt.Errorf`.
