Using type_name in .swiftlint.yml causes incorrect style errors

[sarambasich]

Abstract

If I try to control how type_name rule (length) behaves in my project, any type that IS legal throws an error when run against the linter.

Steps for reproduction

1. Open an Xcode project that has some types declared
2. Add swiftlint
3. Touch .swiftlint.yml file
4. Paste the following into the yml file:

disabled_rules: # rule identifiers to exclude from running
  - trailing_whitespace
  - closing_brace
  - variable_name
  - nesting

type_name:
    min_length: 2
    max_length: 40

variable_name:
    min_length: 500
    max_length: 1000

file_length:
    warning: 1000
    error: 1500

Then compile the project with swiftlint enabled

Expected behavior

Any type names less than two characters and greater than forty characters are flagged as a warning.

Actual behavior

Type names that do fit in the 2-40 range are marked as an error:

Workaround

Remove the rule from the .swiftlint.yml file and no errors are generated.

Attempted resolutions:

• Tried changing the type_name rule to:

type_name:
    min_length: 2
    max_length:
        warning: 40
        error: 50

This caused swiftlint to ignore the rule altogether.

Version

$ swiftlint version
0.8.0

I am not sure if my yml format is invalid or if something else is going wrong. This was not occurring until I brew upgrade'd today to 0.8.0.

Any help would be greatly appreciated. And thank you for this tool and the help.

@jpsim do you think this is the same error as #522 ?

[jpsim]

Yes, this is the same as #522 which has been fixed on master and will be included in the next release.

Thanks for reporting @ArtisOracle!
