Rules file as argument to support multiple projects

[jacobjennings]

It would be nice to specify a rules file as a command line argument, to support having one set of rules for multiple projects.

What were you envisioning for this? A commandline argument? A configuration option in the .swiftlint.yml file that lists a path to this custom rules document?

[jacobjennings]

Either way would be great. I like the configuration option in the .yml idea best

[jpsim]

Maybe we could support external file references in .swiftlint.yml. Maybe if used in backticks?

whitelist_rules: `~/.swiftlint/common_rules.yml`

I think in general it'd be better to have a base_configuration or something like this so this could be solved in a generic way. We'd probably need to implement #676 though.

This isn’t a native solution, but sharing configurations between projects is one of the reasons I started writing Workspace.

If...

1. The only thing you want to configure is to disable rules, and...
2. Your project supports the Swift Package Manager,

...Workspace should already be able to make SwiftLint share its configuration like you want. If your set‐up is more complicated, or if something below does not work properly, raise an issue at the Workspace repository, and I will look into it.

Steps:

1. Read the summary of how to use Workspace.

2. Add Workspace to each project.

3. Create a configuration file like this one in one of the projects, then link to it like this in the other projects.

4. Remove your own .swiftlint.yml from each project to pass control of SwiftLint off to Workspace.

5. (Optional) Either put Workspace in charge of Xcode, or add the following script build phase to your own Xcode project:

~/.Workspace/Workspace/.build/release/workspace proofread

Thanks again to everyone at SwiftLint. Your work is much appreciated.

I would love to reference the config file as a command line argument, or from within .swiftlint.config as @aamctustwo suggested. Ideally our organization could have a git repo for our versioned SwiftLint config file. SwiftLint would support loading the file via git@github.com:... (to bypass 2FA via https) along with a specific tag, similar to how CocoaPods can be referenced.
