Example of ignoring functions outside standard library

[alexflint]

I am attempting to add the function "Println" in the package github.com/kr/pretty to my errcheck ignore file. However, none of the following lines result in the error being excluded:

github.com/kr/pretty.Println
"github.com/kr/pretty".Println
(github.com/kr/pretty).Println
("github.com/kr/pretty").Println
pretty.Println

The command I'm using is (and I can successfully ignore other functions inside the standard library):

errcheck -exclude .lint/errcheck-excludes src.go

The error I see is:

src.go:37:16:	pretty.Println(r)

The function signature is:

func Println(a ...interface{}) (n int, errno error)

hm, maybe it would be useful if there was a flag for also printing the function name alongside the line so that it was easier to make the excludes.

Ah it looks like I can get the full function name with -v and what I needed to put into my exclude file was:

github.com/alexflint/myproject/vendor/github.com/kr/pretty.Println

I understand what's going on here but it doesn't seem very easy to discover.

I have a similar issue with that. The -v is not present and the -verbose flag is not useful. I cannot get how to properly exclude some methods.

What if I am using go modules rather than vendored dependencies?
