Doc does not seem to work?

[arichiardi]

Hey Bruce, quick report :smile:

Example:

[Rebel readline] Type :repl/help for online help info
user=> (doc map)
CompilerException java.lang.RuntimeException: Unable to resolve symbol: doc in this context, compiling:(NO_SOURCE_PATH:1:1) 

Compare with:

nREPL server started on port 43935 on host 127.0.0.1 - nrepl://127.0.0.1:43935

REPL-y 0.3.7, nREPL 0.2.12

          (find-doc "part-of-name-here")

    Exit: Control+D or (exit) or (quit)

user=> 

user=> (doc map)
-------------------------
clojure.core/map
([f] [f coll] [f c1 c2] [f c1 c2 c3] [f c1 c2 c3 & colls])
  Returns a lazy sequence consisting of the result of applying f to
  the set of first items of each coll, followed by applying f to the
  set of second items in each coll, until any one of the colls is
  exhausted.  Any remaining items in other colls are ignored. Function
  f should accept number-of-colls arguments. Returns a transducer when
  no collection is provided.

I launch rebel with:

{:deps {org.clojure/clojure {:mvn/version "1.10.0-alpha4"}
            com.bhauman/rebel-readline {:mvn/version "0.1.3"}}
  ...
       :main-opts ["-m" "rebel-readline.main"]}

Hi @arichiardi

There are two ways you can do that on clojure rebel prompt.

1. By invoking the keybinding C-x C-d on the function name

2. Other way is to use clojure.repl namespace

   
   => (use 'clojure.repl)
   => (doc reify)

I hope this helps.

[arichiardi]

Oh, I thought it was kind of following the normal REPL bindings. Is this planned or do you want me close it.

[metacritical]

I think shortcut is a good thing, though i am not sure if it is planned. I think a good way would be to start the repl with (use 'clojure.repl) though i dont know how to do that when start a repl. Let this be open. I hope someone will tell us how to start deps.edn with dependencies.

[arichiardi]

Yeah I ended up doing exactly that:

user=> (use 'clojure.repl)
nil
user=> (doc var)
-------------------------
var
  (var symbol)
Special Form
  The symbol must resolve to a var, and the Var object
itself (not its value) is returned. The reader macro #'x expands to (var x).

  Please see http://clojure.org/special_forms#var

[metacritical]

I really hope there is some way in ~/.clojure/deps.edn to start repl with native dependencies.

[arichiardi]

Using this at the moment: https://gist.github.com/arichiardi/8ad47f5edf185876e82015739f038a22

[arichiardi]

Ideally rebel-readline.cljs.main should do (use 'clojure.repl) for me? Maybe?

[metacritical]

Your alias doesnt seem to be working for me. My alias is the following for rebel readline:
alias cljrebl='clj -Sdeps "{:deps {com.bhauman/rebel-readline {:mvn/version \"0.1.3\"}}}" -J--add-modules -Jjava.xml.bind -m rebel-readline.main'

[metacritical]

The Java XML bind is used because the latest Java version 10 deprecated java.xml so it needs to be required for clojure to work with latest java.

[metacritical]

I didnt notice the accompanying deps.edn this is good. Thanks!

[arichiardi]

Oh ok, you need alias + deps.edn of course, it is working fine here, I did not want to include the rebel dep in the alias itself because of the escaping stuff.

[prnsml]

You can use -e --eval option to automaticity load lib and add it to namespace with use So, to load rebel with docs from command line:

clj -Sdeps "{:deps {com.bhauman/rebel-readline {:mvn/version \"0.1.4\"}}}" -e "(use 'clojure.repl)(use 'clojure.java.javadoc)" -m rebel-readline.main

Or add this to your deps.edn :aliases :

:rebel {:extra-deps {com.bhauman/rebel-readline {:mvn/version "0.1.4"}}
        :main-opts  ["-e" "(use,'clojure.repl)(use,'clojure.java.javadoc)"
                     "-m" "rebel-readline.main"]}
