pause on save and errors with no errors

[fommil]

I've just started with clojure, this is my complete emacs config

(use-package flycheck-clojure)
(use-package cider)
(add-hook 'clojure-mode-hook
          (lambda ()
            (setq show-trailing-whitespace t)
            (show-paren-mode)
            (whitespace-mode-with-local-variables)
            ;;(focus-mode)
            (rainbow-mode)
            ;;(prettify-symbols-mode)
            (eldoc-mode)
            (flycheck-clojure-setup)
            (flycheck-mode)
            (yas-minor-mode)
            (company-mode)
            (smartparens-strict-mode)
            (rainbow-delimiters-mode)))
(add-hook 'cider-repl-mode-hook #'eldoc-mode)

and my ~/.lein/profiles.clj looks like this

{:repl {
        :plugins [[cider/cider-nrepl "0.11.0"]]
        :dependencies [[acyclic/squiggly-clojure "0.1.4"]
                       ^:replace [org.clojure/tools.nrepl "0.2.12"]]
        }
}

I added the :plugins bit after following the CIDER installation instructions and I added the :dependencies bit after following your instructions (although I think your README is missing a closing }).

I am not seeing any squigglies in my clojure code (my example project is https://github.com/fommil/twitter-teflon/blob/7a1a50b33c6336865ba1d6cf1951750764585cb6/src/fommil/teflon/core.clj ) e.g. if I introduce any errors in that file such as (Thread/slee 1) I don't see anything.

And when I save the buffer, Emacs freezes for a few seconds and I see the following messages in *Messages*

error in process filter: Wrong number of arguments: (4 . 4), 0 [2 times]
Error from syntax checker clojure-cider-eastwood: Done with no errors

enabling debug-on-error and saving the file gives

Debugger entered--Lisp error: (wrong-number-of-arguments (4 . 4) 0)

looks like this might be https://github.com/clojure-emacs/squiggly-clojure/issues/29

[fommil]

by following the hints in the linked ticket, I changed the profiles to

{:repl {
        :plugins [[cider/cider-nrepl "0.11.0"]]
        }
 :user {
        :dependencies [[acyclic/squiggly-clojure "0.1.4"]]
        }
}

and restarted Emacs. I no longer get pauses or errors on save, although errors now fail in a compile phase when I run lein run (which is good) but still no squigglies.

Hey, @fommil , welcome to the Clojure world!

About the errors in checking: I don't believe you're actually using the right (i.e. latest) versions of either cider-nrepl or squiggly-clojure, which might be part of your problem.

Both of these projects now auto-inject these values for you without you having to set up a ~/.lein/profiles.clj at all now (this is a somewhat recent change, so not all documentation is making this overly clear yet). Try just deleting your ~/.lein/profile.clj if you don't have anything not-cider related in it and see if it fixes the problem.

About the long pauses: I have a pull request open to fix this issue (https://github.com/clojure-emacs/squiggly-clojure/pull/38) , but it seems to have hung in having a decision made around it @pnf ?

[fommil]

ok, cool! That actually worked. Let's leave this open as a documentation ticket. i.e. the fix is "ignore the docs, they are wrong."

[tanzoniteblack]

There is a very small comment on it in the documentation (see the paragraph immediately above https://github.com/clojure-emacs/squiggly-clojure#configuration ), but we should probably make that a bit more obvious :) .

[pnf]

@tanzoniteblack I was hoping for a comment from @expez on https://github.com/clojure-emacs/squiggly-clojure/pull/38, as it seemed to be a partial revert of one his commits. I think I'll go ahead and merge it though, as it looks right to me.

[pnf]

@fommil Welcome to clojureland. After your indoctrination is complete, I may enlist you in my effort to foist transducers on a certain scala shop. The configuration instructions are a perennial mess. We should be using squiggly-clojure 0.1.5 and cider-nrepl 0.11.0-snapshot, to be consistent with the "latest" cider. Cloning your repo and using a minimal .lein/profiles.clj that specifies these for the :repl profile, I get the expected

    3   1 warning         Constant value is discarded: "I can say hello."... (clojure-cider-eastwood)

I'm tempted to just refer people to the main cider docs for all cider-related dependencies.

[pnf]

With the last commit, the README encourages use of cider-jack-in dependency injection and refers cider-connecters to the Cider docs for exact version numbers.

[fommil]

I am afraid my indocrination is suffering major problems, as I can't get OAuth 1.0A to work against twitter. Pretty much every auth library I can see in clojure has been dormant for 5 years.

[pnf]

It is a JVM language, you know.
