Thanks. I didn’t even know that leinengen has plugins. If tools.* is the language maintainers’ preferred method, I think there is value in having a single command to set up a “simple/default Clojure project” in a folder, even if that only cuts the commands down from four to one. $ mkdir hello-world $ cp deps.edn hello-world $ cd hello-world $ mkdir src I don’t understand where that deps.edn comes from in a fresh project. It’d be great to have “clj create hello-world” build one for me in ./hello-world, use my running Clojure version as a dependency (if that’s how “clj” works), create the child src/ (and /test if that’s a best practice) folders, etc. The idea being to generate a local library on-demand with sane boilerplate defaults and almost no knowledge. I can learn later what Else I might need if I can get it up and running quickly first. Leinengen looks easier to me for my admittedly trivial use cases, because I don’t need a library or plugins at all. And again, I might be in the minority. But if folks keep saying “lein handles 90% and is easier,” and if we can make tools.* handle those same 90% cases trivially, it seems worthwhile.

  You don't even need that -- those are the defaults for the CLI. (! 639)-> mkdir fresh && cd fresh (! 640)-> mkdir -p src/myns (! 641)-> echo '(ns myns.myfile) (defn foo [{:keys [name]}] (println (str "Hello, " name "!")))' > src/myns/myfile.clj (! 642)-> clojure -X myns.myfile/foo :name "filoeleven" Hello, filoeleven! No deps.edn file needed -- until you want to add extra dependencies etc.
