What's it all about, Alfie?

A couple of days ago, I found out about the licensing rules for JDK 11 from Oracle, and wanted to install OpenJDK 11 with Homebrew. Sadly, Homebrew doesn't really like the idea of installing older versions of packages, so I'm going to live with JDK 1.8, and OpenJDK 11. But that's not what this is about. 🙂 This is about Clojure, and Leiningen's REPL, and the fact that in that post I found a known problem with the current version of Ultra, and Leiningen versions greater than 2.7.1

Well... a little digging, and I find that the core component of Ultra is another project, and that same author has a similar REPL formatter and colorizer - called whidbey. Now it turns out that whidbey also has issues with Leiningen 2.9.0 - but at least it works with 2.8.3, so I can upgrade to 2.8.3, and then let them figure out the issue with nREPL 0.6.0 - as it's already an issue on whidbey.

So until then, I have both in my ~/.lein/profiles.clj, and I can flip between the two as needed:

  {
   :user {:plugins [[lein-exec "0.3.7"]
  ;                  [venantius/ultra "0.5.4"]
                    [mvxcvi/whidbey "2.0.0"]
                    ]
          :middleware [whidbey.plugin/repl-pprint]
          :whidbey {:color-scheme {:delimiter [:bold :yellow]
                                   :tag [:bold :yellow]
                                   :nil [:cyan]
                                   :boolean [:bold :cyan]
                                   :number [:bold :green]
                                   :string [:bold :red]
                                   :character [:cyan]
                                   :keyword [:yellow]
                                   :symbol [:bold :magenta]
                                   :function-symbol [:bold :blue]
                                   :class-delimiter [:blue]
                                   :class-name [:green]
                                   :exception [:bold :red]}}
          :ultra {:color-scheme ;; :solarized_dark
                   {:delimiter [:bold :yellow]
                    :tag [:bold :yellow]
                    :nil [:cyan]
                    :boolean [:bold :cyan]
                    :number [:bold :green]
                    :string [:bold :red]
                    :character [:cyan]
                    :keyword [:yellow]
                    :symbol [:bold :magenta]
                    :function-symbol [:bold :blue]
                    :class-delimiter [:blue]
                    :class-name [:green]
                    :exception [:bold :red]}}
          }
  }

At this point, I can switch to 2.8.3 with:

  $ brew switch leiningen 2.8.3
  Cleaning /usr/local/Cellar/leiningen/2.7.1
  Cleaning /usr/local/Cellar/leiningen/2.9.0
  Cleaning /usr/local/Cellar/leiningen/2.8.3
  3 links created for /usr/local/Cellar/leiningen/2.8.3

and I'm good to go with Leiningen 2.8.3, and as soon as whidbey is updated, I'll be able to move up to 2.9.0. Really glad I found this project.

[3/6] UPDATE: it looks like ultra is getting an update that will allow it to work with Leiningen 2.9.0 - which is great! I just need to wait for ultra 0.6.0 to hit Clojars, and I can update and use it. That would be very nice!
