Exception while launching the boot repl

[arichiardi]

Expected behavior

The repl starts when you execute boot cider repl wait at the terminal.

Actual behavior

An exception is thrown.

Steps to reproduce the problem

At the terminal boot cider repl wait

Environment & Version information

CIDER version information

0.12.0-SNAPSHOT (master)

Lein/Boot version

boot 2.5.5

Emacs version

24.5

Operating system

Ubuntu Linux 14.10

The exception involves fipp and it is here.

My cider task is:

(deftask cider
  "Add CIDER support:
   https://github.com/boot-clj/boot/wiki/Cider-REPL"
  []
  (require 'boot.repl)
  (swap! boot.repl/*default-dependencies*
         conj '[cider/cider-nrepl "0.12.0-SNAPSHOT"])
  (swap! boot.repl/*default-middleware*
         conj 'cider.nrepl/cider-middleware)
  identity)

Removing the cider, removing the middleware, successfully launches the repl.

What do you mean by this? Do you mean you ran this command in a terminal?

I think @benedekfazekas might recognize this exception.

[arichiardi]

Yes sorry, at the terminal, but it happens with jack-in as well.

[benedekfazekas]

well I don't but luckily you can search gitter history ;)

based on that it seems we had the same problem with leiningen prior version 2.5.3. no immediate memory how older lein version caused this. just a stab in the dark: what is your clojure version btw?

also a possible workaround could be if you set (setq cider-pprint-fn 'pprint), at least for cider-jack-in

also you only need the cider task if you want to use a separate REPL, cider-jack-in sorts out dependencies (wonder if you get the same exception if you use that.) for itself

[arichiardi]

Thanks @benedekfazekas! Clojure version is 1.6.0 which is the minimal supported version that boot supports...it might be that then. I am trying...

[arichiardi]

Bumping the version solves, so I can live with this, so basically 1.6.0 is not officially supported anymore for boot right? I would like to add it in their wiki.

REPL-y 0.3.7, nREPL 0.2.12
Clojure 1.7.0
Java HotSpot(TM) 64-Bit Server VM 1.8.0_77-b03

[benedekfazekas]

this may be a reader conditionals related issue then.

[arichiardi]

The wiki page is this and as you were saying before I gather that also the "A better way" section is not required anymore (since 0.11.0?)

[benedekfazekas]

well I guess you can't use stuff with 1.6 that uses reader conditionals. incl. refactor-nrepl as we use some stuff using cljc files. it seems same goes with cider-nrepl as well then?

A better way section only applies if you want to use cider (and refactor-nrepl) with REPL you connect to instead of using cider-jack-in. see this for details

[arichiardi]

Ok then, I guess I have to specify it there so that people don't get bitten. Boot still supports back to 1.6.0

[arichiardi]

Ok done: https://github.com/boot-clj/boot/wiki/Cider-REPL, closing this.

thx!
