Clojure CLI deps.edn for Emacs CIDER

Including aliases in .dir-locals.el

Set the scope of the entries, using clojure-mode is usually preferable

Define the CIDER specific variables to use

• CLOJURE-CLI-ALIASES
• CLOJURE-BUILD-TOOL

which others are useful to add

global options has been replaced by aliases

Dont forget to revert the current buffer after editing the .dir-locals.el file to force Emacs to load that file.

Use C-u before cider-jack-in command to see the command before it is run (and edit if necessary)

Open the *messages* buffer to check the command that has been run.

Manually editing the command

The universal argument, C-u, (SPC-u for Spacemacs) before runnnig the jack-in command allows editing of the command

By default CIDER uses the :cider/nrepl alias, which must remain the last alias used in any chain of aliases (or CIDER wont start unless the last alias also included all the same libraries and middlware as the :cider/nrepl alias)

Useful aliases

• :test - add test path so the cider test runner can find the test code on the class path, otherwise it will fail to find the tests (include the error if this path is not included.
• :dev - add dev path to include a dev/user.clj file on the class path, allowing the REPL to be configured by loading the custom user namespace. Launch things like portal, a place to start stop components with IntegrantREPL, etc.

Update ClojureVerse discussion

As the configuration of CIDER has changed for the Clojure CLI, the original advice on https://clojureverse.org/t/how-to-setup-deps-edn-project-with-cider/6375/15 is out of date and can break cider

Raise a new question and refer to the old discussion (which can no longer be updated). This is the preferred way to manage content that is out of date on ClojureVerse.

Locate the relevant Clojure CLI and CIDER documentation, then review the .dir-locals.el and deps.edn guidance against the linked ClojureVerse discussion. Update the outdated setup advice and raise a new ClojureVerse question referring to the old discussion; done means the repository no longer directs users to the breaking advice.
