https://github.com/spf13/viper/blob/5870123c5f385c8d88b7087d15d2e1b7fa67a7fa/README.md?plain=1#L144
That line of the readme is a bit confusing. It took navigating the git blame history to find https://github.com/spf13/viper/commit/9cd571279d195d6a02b5103f0301d8310dd4338d and reviewing the commit in context for me to understand that it is saying a file named ~/.foo can be loaded as YAML when viper.SetConfigType("yaml") is used.
I was looking for a way to support the following file path possibilities:
/etc/foo/config.yaml$HOME/.foo$HOME/.foo.yaml./.foo./.foo.yaml
It's still not clear to me if I can support that list.

@jsumners I don't think it's possible with the current implementation. I agree it's confusing, not very well explained and evolved in the wrong way over time.
I opened #1795 with a proposal for a better file searching API.
Here is how it would work in your case:
finder := locafero.Finder{
Paths: []string{".", "$HOME", "/etc/foo"},
Names: []string{".foo", ".foo.yaml", "config.yaml"},
Type: locafero.FileTypeFile,
}
v := viper.New(viper.WithFinder(finder))
The above is still not perfect though since it would allow results like $HOME/config.yaml.
I opened sagikazarmark/locafero#26 to address that. Considering that proposal, here is how it would roughly look like:
finder := locafero.AggregateFinders(
locafero.Finder{
Paths: []string{".", "$HOME"},
Names: []string{".foo", ".foo.yaml"},
Type: locafero.FileTypeFile,
},
locafero.Finder{
Paths: []string{"/etc/foo"},
Names: []string{"config.yaml"},
Type: locafero.FileTypeFile,
},
)
v := viper.New(viper.WithFinder(finder))
You could potentially play with supporting multiple file types if you wanted to.
What do you think? Would this suffice your needs? (Your feedback would be very helpful as I just started to work on this solution, so I'm looking to validate this new API)
