Can't change/establish root binding of: *cljs-repl-options* with set

[EduardoMRB]

I'm trying to get piggieback to work on my project and I just can't.

I think that it has something to do with nrepl-middleware in project.clj so I'll post it here to see if I'm doing something stupid.

I'm having the same problem. I made it work with Clojure 1.6.0 instead of 1.7.0-alpha5, but I don't remember what other changes I made.

This is also an issue with Weasel, here: https://github.com/tomjakubowski/weasel/issues/40

[cemerick]

Unrelated, ClojureScript 0.0-2913 seems to be borked; I consistently get Namespace "goog.string" already declared when starting the compiler, which then tosses an exception.

I took both @alexandergunnarson's and @EduardoMRB's project files, and was able to use each of them as-is (with the exception of updating the ClojureScript dep to 3058):

$ lein repl
...
tasks.server=> (require 'cljs.repl.node)
nil
tasks.server=> (cemerick.piggieback/cljs-repl :repl-env (cljs.repl.node/repl-env))
ClojureScript Node.js REPL server listening on 51829
Type `:cljs/quit` to stop the ClojureScript REPL
nil
cljs.user=> (reduce + #js [1 2 4])
7
cljs.user=> js/process.env.LANG
"en_US.UTF-8"

I tried to replicate the issue with different versions of clojure, java, and leiningen, but with no success (failure!).

I see elsewhere that people are having trouble using piggieback with trampoline; that's not going to work (see #34).

I'm unfortunately at a loss as to what might be causing this issue for some people. Clearly some environmental issue, but nothing obvious comes to mind now that project.clj configuration has been ruled out.

I see no one has bothered to actually drop a stack trace on this one :)

@j-mckitrick yes OK the problem is quite simple. ClojureScript recently in order to not change the function / protocol level API while getting REPL options to all REPL evaluation environments in all cases (even if not taken explicitly as an argument) establishes a root binding for *cljs-repl-options* via binding in the usual way. However piggieback being nREPL middleware doesn't have the usual REPL loop, it must establish the root binding itself (if not already established) where relevant.

[jmckitrick]

Hmm. So that means... there's not a solution yet with the current versions of ClojureScript?

@j-mckitrick it needs to be fixed in piggieback.

[cemerick]

@swannodette I think you're talking about cljs.repl/*repl-opts*? *cljs-repl-options* is a var defined in piggieback, and is the one that piggieback is failing to set! in the stack provided by @j-mckitrick.

Piggieback doesn't touch the cljs.repl/*repl-opts* var at all; that doesn't seem to hinder usage in any way though, as I can bring up and use a ClojureScript REPL using 3058 and piggieback without a problem. Somehow, the piggieback nREPL middleware isn't being put into place properly, despite the project.clj configuration looking right.

[cemerick]

This seems like a longshot, but could someone who is affected by this try requiring nREPL 0.2.7? It looks like Leiningen is currently defaulting to 0.2.6; 0.2.7 fixes the topological sort applied to REPL middleware. To do this, add [org.clojure/tools.nrepl "0.2.7"] to your :dev profile's :dependencies, and try to start a ClojureScript REPL via piggieback: (cemerick.piggieback/cljs-repl)

(FWIW, clojure.tools.nrepl/version will indicate 0.2.7 if the explicit nREPL dependency has properly overridden Leinigen's default.)

[swannodette]

@cemerick oh you're right, apologies for the noise.

[alexandergunnarson]

@cemerick I updated the dependencies with [org.clojure/clojurescript "0.0-3058"] and the dev dependencies with [org.clojure/tools.nrepl "0.2.7"]. Otherwise my project.clj looks the same way. I unfortunately still have the same error as before.

[EduardoMRB]

@cemerick with [org.clojure/clojurescript "0.0-3058"] and [org.clojure/tools.nrepl "0.2.7"] I was able to start a repl with no problems, thank you for your help.

@alexandergunnarson clojure.tools.nrepl/version outputs the correct version of nrepl?

[alexandergunnarson]

@EduardoMRB — never mind, I just realized I was using lein trampoline (I was just calling a SublimeREPL command I had previously customized a while ago). Apparently that doesn't work for some reason, but lein repl works perfectly for me. Sorry for the confusion.

[cemerick]

Excellent; I think we're 2 of 3 reports now working with nREPL 0.2.7 to eliminate the middleware linearization nondeterminism. Any word, @j-mckitrick?

[jmckitrick]

Let me look at this tonight and get back to you.

[cemerick]

The work on the new-cljs-repl branch, currently available in 0.2.0-SNAPSHOT, is effectively a rewrite due to the new ClojureScript REPL API, etc. Closing all issues filed against 0.1.x; most (or all) of them should be resolved and/or irrelevant.
