Doesn't work with dot in config file name.

[whmountains]

I get configuration file "default.settings" not found when I try to load a file called "default.settings.toml". The code looks like this:

let mut settings = config::Config::default();
settings
    .merge(config::File::with_name("default.settings")).unwrap();

I didn't dig too deep (that was a lie) but probably if you have a dot without the real extension it recognizes it as the file extension and doesn't apply the one you use. In this case, it thinks your extension is .settings so it doesn't add .toml to it in this method: https://github.com/mehcode/config-rs/blob/master/src/file/source/file.rs#L27. (wrong, check comment below) If you explicitly set default.settings.toml it works.

https://github.com/mehcode/config-rs/blob/master/src/file/source/file.rs#L33 here it will return false since the file ./default.settings doesn't exist.

Now we are here https://github.com/mehcode/config-rs/blob/master/src/file/source/file.rs#L60,
it tries to apply known extensions but since your extension is .settings it basically replaces it, creating default.toml and that again doesn't exists, in the end it will just fail here https://github.com/mehcode/config-rs/blob/master/src/file/source/file.rs#L80

So basically, this problem is in the PathBuf and not in this library. Here is an example:

Is this still an issue? If yes, can you provide patches?

[CfirTsabari]

i fixed it in #306

[CfirTsabari]

@matthiasbeyer can we get a new version with this fix? It didn't get into 0.13.0

[matthiasbeyer]

Yep: #313
