Ignore function lines lint

[liubog2008]

Sometimes we need to init a huge structure which must consume more than 60 lines. It can't be split to multiple function.

Could you provide an example please? I am having a hard time understanding your issue

[liubog2008]

func initData() *Data {
    return &Data {
      ... // more than 60 lines
    }
}

especially in *_test.go

There are multiple options:

This will disable the function is to long warning for funlen in test files

exclude-rules:
  - path: "_test.go$"   # Files that this rule applies to
    text: "is too long" # Ignore when the warning includes this text
    linters:            # All linters that this rule applies to
      - funlen

You could increase the function length setting and keep the statements setting default... Note that this applies to all files in your project

linters-settings:
  funlen: # tweak these to your liking
    lines: 60
    statements: 40

You could //nolint: funlen the specific functions

//nolint: funlen
func initData() *Data {
    return &Data{
        ... // more than 60 lines
    }
}

Could you add an option to just disable lines lint?

e.g.

linters-settings:
  funlen: # tweak these to your liking
    lines: -1
    statements: 40

This could be achieved by using the first example but without the path filter:

exclude-rules:
  - text: "is too long" # Ignore when the warning includes this text
    linters:            # All linters that this rule applies to
      - funlen

I could make a change to accept -1 to disable either lines or statements, but it would probably take a while to be in a golangci-lint release
