Add deps.edn for usage as a library

[jeroenvandijk]

Adding a deps.edn file allows me to use this code as a library to print formatted code:

(require 'cljstyle.format.core)
(defn reformat-code [code]
  (str (cljstyle.format.core/reformat-string (pr-str code))))

Thank you!

Hi Greg,

Yeah I'm using it locally via tools.deps. Unfortunately tools.deps doesn't work for git libs when the deps.edn is a nested dir. But if you use git submodules for instance and a local path it works:

mkdir vendor
git submodule add git@github.com:jeroenvandijk/cljstyle.git vendor/cljsstyle
git submodule update

Then I have the following deps.edn:

{:paths ["src"]
 :deps {
   cljstyle { :local/root "vendor/cljstyle/core" }
 }
}

(I actually think it would be nice if submodule stuff was supported out of the tools.deps box)

I'll merge this as-is, but I have been considering merging the core and tool projects anyway, which would simplify this a lot.
