The paradox is that you can have a simulacra of those features with 
ClojureScript by using :source-map and  Chrome Developer Tools. But AFAIK you 
loose something at the moment (e.g. cljs completion, cljs documentation). 

That said, when the scenario allows it, I always write portable CLJ/CLJS code 
by using cljx plugin. This way I can have an almost full powered REPL 
experience with CLJ REPL and when I really need to set breakpoints or inspect 
locals  (very rare), I switch to CLJS….

Re: clojure debugging repl

2014-01-25 Thread t x 
https://github.com/GeorgeJahad/debug-repl/blob/master/src/alex_and_georges/debug_repl.clj

is some of the most enlightening clojure code I have read.


Any other suggestions?

Criteria for code I'm looking for:

* need not be production use

* ideally short

* focus is "demonstrate key idea, not necessarily worry about production
use"

 It appears cider does not yet support this, so ritz is probably the
 "most powerful" at the moment.

Re: clojure debugging repl

Its a part of Chapter 17, just so you know its only a small exercise 
showing the beauty of Clojure, Lisp and Macros.  Its only about 6 six 
pages.  The footnote:

The code in this section is based on *debug-repl* created by the amazing 
George Jahad,
extended by Alex Osborne, and integrated into Swank-Clojure by Hugo Duncan.

So maybe check those out.  That said I think its a really good book and 
Manning often has specials going so you get Joy of Clojure 1 & 2 for cheap.

 Hi,

   One thing I miss from pre-Clojure scheme days is as follows:

 ## What I want

 1 => (foo) ;; I'm calling foo at the repl
 ... foo executes ...

 2 => my interpreter _starts a new repl_

 ## Why "it can't work"

 Now, I understand why this can not work in general in Clojure, i.e. the 
 following example:

 (defn foo []
   (.someJavaFunctionThatThrowsException object))

 In this case, the above is impossible since the exception is thrown 
 from _java land_ rather than Clojure land.


 ## Why it might work

 Now, I'm not writing any code in java. The work I'm doing is pure 
 clojure. I can throw when the exception is thrown.


 Is there some library, where instead of doing

 (defn foo []
   ...
   (throw (ex-data ...))
   ...)

 I instead do:

 (defn foo []
   ...
   (something-went-wrong-please-fire-up-a-repl)
   ...)

 ?
  
 Thanks!

Re: clojure debugging repl

2014-01-24 Thread Alexandr Kurilin 
I've been looking for a simple and convenient to use clojure debugger for
ages now and would love to hear your recommendations. I'm a vim-fireplace
user as well, if that makes a difference.

I'd love to be able to set breakpoints in a running clojure application,
step through the code and inspect locals and the referencing environment.
Anything that gets me off of the time-consuming process of adding
timbre/clojure.tools.trace statements would be really welcome. Is vim-redl
the closest I can get to that, or is ritz the way to go? Any other
recommendations?

I'll have to checkout JoC2's chapter on that, that sounds really helpful.

Re: clojure debugging repl

2014-01-24 Thread dgrnbrg 
I have an implementation of this that's thoroughly integrated into vim.

clojure code: https://github.com/dgrnbrg/redl
vim plugin: https://github.com/dgrnbrg/vim-redl

The code itself is written with core.async, and is capable of monitoring a 
thread, inspecting its stack while its running, stopping it, and 
programmatically creating breakpoints that give you a repl with captured 
locals.

I'd love for this work to be extended to a generic nrepl handler, but I 
don't have the time to do so at the moment.

The second version of The Joy of Clojure talks about building a debugging

Re: clojure debugging repl

Found it, apparently it's

debug-repl => swank-clojure => CDT => ritz

It appears cider does not yet support this, so ritz is probably the "most
powerful" at the moment.

clojure debugging repl

2014-01-24 Thread t x 
Hi,

  One thing I miss from pre-Clojure scheme days is as follows:

## What I want

1 => (foo) ;; I'm calling foo at the repl
... foo executes ...
... at some point, an exception is thrown ...

2 => my interpreter _starts a new repl_
  * at the point where the exception was thrown
  * lets me examine local environment variables
  * lets me execute commands
  * lets me "resume" the execution


## Why "it can't work"

Now, I understand why this can not work in general in Clojure, i.e. the
following example:

(defn foo []
  (.someJavaFunctionThatThrowsException object))

In this case, the above is impossible since the exception is thrown from
_java land_ rather than Clojure land.


## Why it might work

Now, I'm not writing any code in java. The work I'm doing is pure clojure.
I can throw when the exception is thrown.


Is there some library, where instead of doing

(defn foo []
  ...
  (throw (ex-data ...))
  ...)

I instead do:

(defn foo []
  ...
  (something-went-wrong-please-fire-up-a-repl)
  ...)

?

Thanks!
