Demonstrates error with shadow-cljs and > cider 0.16

• If using Cider v 0.16
  • Edit shadow-cljs.edn, set [cider/cider-nrepl "0.16.0"]
  • Edit emacs-config2, uncomment the el-get statement for 0.16
  • docker-compose down && docker-compose up
  • Wait a while
  • Go to http://localhost:10000/index.html?server=localhost&port=10000&encoding=auto&keyboard_layout=gb&submit=true&clipboard=true&password=111&insecure=true
  • If it asks for password, enter 111
  • You should see emacs interface
  • Everything should be installed
  • Open src/mattsum/bug_test/core.cljs
  • M-x cider-connect Host: shadow-cljs Post: 9991
  • In the repl buffer
    • (shadow.cljs.devtools.api/watch :bug-test)
    • (shadow.cljs.devtools.api/nrepl-select :bug-test)
  • In core.cljs, type M-x, then cider-repl-set-ns
  • Edit file, add (defn) to force syntax error
  • Everything should work, correct error (“Call to cljs.core/defn did not conform to spec”)
• If using Cider v 0.17
  • Edit shadow-cljs.edn, set [cider/cider-nrepl "0.17.0"]
  • Edit emacs-config2, uncomment the el-get statement for 0.17
  • docker-compose down && docker-compose up
  • Wait a while
  • Go to http://localhost:10000/index.html?server=localhost&port=10000&encoding=auto&keyboard_layout=gb&submit=true&clipboard=true&password=111&insecure=true
  • If it asks for password, enter 111
  • You should see emacs interface
  • Everything should be installed
  • Open src/mattsum/bug_test/core.cljs
  • M-x cider-connect Host: shadow-cljs Post: 9991
  • M-x cider-create-sibling-cljs-repl shadow bug-test
  • In core.cljs, type M-x, then cider-repl-set-ns
  • Edit file, add (defn) to force syntax error
  • In repl, you’ll see [:bug-test] Compiling … In console, you’ll see the following error:
