Thanks Ngoc, it works. But, still can't debug and profile, like Bill
Clementson's introduction.<br>
<br>
When I type C-c C-d i, it looks like is interpreting forever, and can't
set breakpoints to debug. I've checked the archive of this mailling
list, there is only one unresolved thread here:<br>

Do you have more suggestions? TIA.<br>

I think I've resolved this. Just load module (C-c C-d L) before being
interpreted. So simple. <span class="moz-smiley-s6"><span> :-[ </span></span><br>
<br>
In Distel, load module will tell you nothing more than "load: [module
test_ring]", except the first time is successful, in which scenario, it
will tell you "Successfully uploaded backend modules into node". So,
It's difficulty to know whether or not the module was loaded
successfully. <br>
<br>
And, one module can be loaded only if it's beam has been compiled by
the flag: debug_info. <br>

<pre wrap="">Hi all,
To build a erlang IDE, I've tried Distel in emacs22. but unfortunately it
does not work well. What I've done is exactly in accordance with Bill
Clementson's blog post:
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://bc.tech.coop/blog/070528.html">http://bc.tech.coop/blog/070528.html</a>
They are:
Download the latest code from : <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://distel.googlecode.com/svn/trunk/">http://distel.googlecode.com/svn/trunk/</a>
Modify the .emacs. I did confirm the load-path and distel-dir settings are
correct. Here is it:
;; This is needed for Erlang mode setup
(setq erlang-root-dir "/usr/local/lib/erlang")
(setq load-path (cons "/usr/local/lib/erlang/lib/tools-2.5.1/emacs"
load-path))
(setq exec-path (cons "/usr/local/lib/erlang/bin" exec-path))
(require 'erlang-start)
;; This is needed for Distel setup
(let ((distel-dir "/Users/bc/Projects/distel/elisp"))
(unless (member distel-dir load-path)
;; Add distel-dir to the end of load-path
(setq load-path (append load-path (list distel-dir)))))
(require 'distel)
(distel-setup)
;; Some Erlang customizations
(add-hook 'erlang-mode-hook
(lambda ()
;; when starting an Erlang shell in Emacs, default in the node name
(setq inferior-erlang-machine-options '("-sname" "emacs"))
;; add Erlang functions to an imenu menu
(imenu-add-to-menubar "imenu")))
;; A number of the erlang-extended-mode key bindings are useful in the shell
too
(defconst distel-shell-keys
'(("\C-\M-i" erl-complete)
("\M-?" erl-complete)
("\M-." erl-find-source-under-point)
("\M-," erl-find-source-unwind)
("\M-*" erl-find-source-unwind)
)
"Additional keys to bind when in Erlang shell.")
(add-hook 'erlang-shell-mode-hook
(lambda ()
;; add some Distel bindings to the Erlang shell
(dolist (spec distel-shell-keys)
(define-key erlang-shell-mode-map (car spec) (cadr spec)))))
When I open a .erl file, it works well and Distel dose exist in the Erlang
tag of the emacs' menubar. But when I type C-M-i behind the word "cr" to
complete the function name,the emacs received this message:
Unexpected reply: [rex [badrpc [EXIT [undef ([distel rpc_entry (distel
modules ("cr"))] [rpc -handle_call/3-fun-0- 5])]]]]
I checked the code in Distel, it looks like that it will call completions()
which will call the get() by the argument:A an empty string("") in
otp_doc.erl. The function get() will call to_list() on the argument:A,which
will get the error:
*** ERROR: Shell process terminated! ***
=ERROR REPORT==== 8-Sep-2009::15:02:42 ===
Error in process <0.66.0> on node 'emacs@doubleclick' with exit value:
{undef,[{lib,format_exception,[4,error,undef,[{erl_internal,bif,[to_list,1]},{erl_lint,expr,3},{erl_lint,exprs,3},{erl_lint,exprs_opt,3},{erl_eval,check_command,2},{shell,exprs,6},{shell,eval_exprs,6},{shell,eval_loop..
I guess this is the reason for the completion failure, but have no idea how
to fix it. Can anyone here give me some advice?
As a newbie in Erlang, it's very possible I've stepped in the wrong
way.However, any suggestions will be appreciated.
Thanks in advance.
Eric
