Re: How do I use spec and deftype together?
Just in case someone stumbles over this post, I found a simple solution which works for me: (do (require '[clojure.spec.alpha :as s]) (import '(clojure.lang ISeq)) (defprotocol Foo (foo [this])) (defrecord Bar [bar] Foo (foo [this] (.bar this))) (deftype Baz [bar] Foo (foo [this] (.bar this)) ISeq (seq [this] `(~(.bar this (s/def ::bar number?)

Re: What is the minimal Emacs config for practical Clojure development?
I tried Monroe, yesterday. It seems to work as advertised. I didn't have any issues. It's nice that "jump to definition" works out of the box. It does not appear to support Eldoc, so no help with function signatures. This is the Emacs config I'm currently using: ;;; clojure-mode (add-to-list 'load-path "~/.emacs.d/site-lisp/third-party/clojure-mode/") (require 'clojure-mode) (add-hook 'clojure-mode-hook 'rainbow-delimiters-mode) (add-hook 'clojure-mode-hook 'paredit-mode) (add-hook 'clojure-mode-hook 'hs-minor-mode) (add-hook 'clojure-mode-hook #'eldoc-mode) ;;; REPL ;; Monroe (add-to-list 'load-path "~/.emacs.d/site-lisp/third-party/monroe/") (require 'monroe) (add-hook 'clojure-mode-hook 'clojure-enable-monroe) (setf monroe-detail-stacktraces 'true) I went on to include Figwheel. I created a new project using `lein new figwheel my-project` (which provides the fig-start and cljs-repl functions), and then entered the following commands to set up a Clojurescript dev environment: M-x monroe-nrepl-server-start M-x monroe (fig-start) (cljs-repl) On my machine, those 4 steps take about 30 seconds to run. The first takes 18 seconds, and the rest only take about a second each, but the whole process ends up taking close to 30. Figwheel seems to work great, but I couldn't figure out how to evaluate code in a library dependency and have it updated in the running system. I can evaluate functions, but the new definitions don't appear to be called by the main code. I might be misunderstanding how this is supposed to work; I don't know if it's a Figwheel issue or a Monroe issue or my mistake. But to work around that, and to fix other issues preventing a clean initial compilation, I had to restart the REPL a few dozen times, which was tedious. I'm posting this information in case it is useful to someone else who is trying to discover the current state-of-the-art with running Clojure in Emacs in a straightforward, minimal way. I'm also hoping that people will reply with comments and suggested improvements. (FWIW, I've been using Emacs full-time for about 20 years, Clojure full-time for about 7 years, and Common Lisp for 5+ years before that, so I'm not new to REPL-driven development in Emacs.) -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: What is the minimal Emacs config for practical Clojure development?
If ClojureScript repl integration works smoothly out of the box then that's already one reason to use it over Cider...

Re: What is the minimal Emacs config for practical Clojure development?
I'm not sure the desires for lightweight clojure-emacs integration and any CLJS integration are yet sympathetic. Figwheel is a pretty complex piece of software. For example, see my issue that has been languishing for almost a year and hints at greater problems with the compiler integration: https://github.com/bhauman/lein-figwheel/issues/593 . From my perspective, this is more due to coupling of the REPL to the compiler itself than a problem with figwheel. But I was surprised when the thread went in this direction just from reasons I think someone might want to not use cider, fast startup time, less stuff to go wrong. CLJS adds that back unless it's gotten significantly better since the last time I tried.

Re: What is the minimal Emacs config for practical Clojure development?
Gary, I had tried Figwheel a couple years ago and I had a positive experience, so that was the next thing I reached for. I just want a practical dev environment, for both Clojure and Clojurescript. To me, that means simple and stable. I definitely want fewer things that can go wrong, but if I can install a package by cloning a repo and adding a few lines of elisp, and it works, I'm happy. I don't care how complex it is. If it causes my REPL to hang, prints out control characters, regularly breaks after updates, etc., then I'd rather drop down to something simpler, with fewer features. For Clojurescript, I've used lein-cljsbuild in the past. That seemed to work well. I know I've connected to a REPL running in the browser before, but I don't remember it being useful enough to bother with. I don't think I knew how to write "reloadable code", then, though. I would love to hear how people do Clojurescript development today, especially if they aren't using Figwheel.

Re: What is the minimal Emacs config for practical Clojure development?
There is one more trick though. The new cljs.main allows you to have a socket repl for ClojureScript. This can then be used with `inf-clojure`. It will not be fancy and probably things will be broken though...the code path has not been seen much love. I did some experimentation and it definitely works - quite smoothly in fact - but I have never have time to make it "production" ready :) On Thursday, July 5, 2018 at 1:01:14 PM UTC-7, Austin Haas wrote: > > Gary, I had tried Figwheel a couple years ago and I had a positive > experience, so that was the next thing I reached for. > > I just want a practical dev environment, for both Clojure and > Clojurescript.

Re: What is the minimal Emacs config for practical Clojure development?
Luminus has a leiningen template which works out-of-the-box with Cider and figwheel. Just (start-fw) and (cljs) inside the repl. It would be nice if we could have both repls open simultaneously within emacs, but everything was super unreliable the last time I tried that. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
