Emacs 23 + Erlang + Distel - emacs

Where I can find current example of configuration and using Distel with Emacs 23 (on Mac Snow Leaoprd). I have problem with debugging (interpret mode), I cant mark brakepoint.
If anyone have working configuration of distel on emacs 23, please share with me.

one problem with using the debugger in distel is that I always need to ensure distel is loaded before setting one.
load a file, put io:format("",[]), then press M-. to navigate to io.erl, that makes sure distel is loaded
now make sure the file is intepreted, C-c, C-d, i, the minibuffer will show
now C-SPACE your line, the mark should appear

try this steps:
C-c C-d g
Then
C-c C-d i
C-c C-d m
C-x 4 0
C-c C-d m
Or in other order, but you should kill monitor buffer, until get not empty buffer with line like this:
PID Initial Call Status Info
After try mark line for breakpoint

I've started with the same version of Emacs. I had a similar problem.
Here's what worked for me:
1 In .emacs file I specify the name of the node with which the erlang shell is executed in Emacs
(setq inferior-erlang-machine-options '("-sname" "emacs"))
2 In Emacs in Erlang mode (just open an erl file):
2.1 I set the node name for Distel C-c C-d n
2.2 Load the Distel to the node with C-c C-d g
After this I am able to set the breakpoint.

emacs - Kill the buffer with terminal emulator

I am aware of this option:
Kill the *terminal* buffer with C-d
But I am still a newbie in emacs, what is the original method to do this? I tried C-x k but it doesn't like it, C-x C-c kills all my windows and buffers...
I assume you're using a buffer in term-mode (M-x term). term-mode is a bit different than most modes in that it has two submodes, char and line. In char mode it acts more like a terminal than emacs, as in a lot of normal keybinds are not available. Put it in line mode with C-c C-j to put it in line mode, then you can run most normal keybinds including C-x k. You can put it back into char mode with C-c C-k.
I use the multi-term package, which I think has better defaults than plain term-mode and as the name suggests makes it easy to have many terminal buffers.

How can I reload .spacemacs file after editing without restart emacs?

I am new to emacs(spacemacs), and I follow this article to learn spacemacs.
Once you are done editing, save the file and either press C-c C-c in the file to reload it or just restart Spacemacs.
But after I save the .spacemacs and then press C-c C-c, the powerline told me C-c C-c is undefined.
How can I reload .spacemacs file after editing without restart emacs?
I found the solution: SPC f e R
It is from "Dotfile Configuration" in the Spacemacs Docs.
SPC f e R doesn't work for me so I personally use SPC q R. It completely restarts spacemacs though - but if you maintain sessions (dotspacemacs-auto-resume-layouts t) in config), spacemacs will restart with same buffers. Hope it'll help someone.
dotspacemacs-auto-resume-layouts is a config option which can be found in setq-default section of your .spacemacs file. It comes with default spacemacs setup, it's default value is nil.
For those who work in emacs mode, it might be little difficult to get this done with keybindings. In such case, do M-X then type dotspacemacs/sync-configuration-layers
SPC q r or (restart-emacs-resume-layouts) will restart emacs whilst preserving the layout.
Another way to do this is press space twice (SPC SPC) which brings you into the emacs command mode.
Then type: sync-config and press Enter which will execute the dotspacemacs/sync-configuration-layers command and reload your config.

Highlight julia code in emacs

I would like to write julialang code in emacs. Is there an easy way to do it like, for example, when you do python code (all these reserved words in colors and indentation)?
Here is what I have done so far:
I created the file
~/.emacs.d/init.el
with the line (after cloning https://github.com/emacs-ess/ESS/wiki/Julia):
(load "/path-to-ESS/ESS/lisp/ess-site.el")
julia is in my path also. Still, emacs does not recognize julia code
I think that this may help. It seems to be emacs support for Julia.
emacs-ess / ESS
Julia
Overview
ESS support for julia language, among other things, includes
font-lock, indentation, sending code to sub-process, interactive
documentation, imenu, completion and eldoc.
Usage
Start
To start julia type M-x julia RET. You can start multiple julia
processes if you so desire.
To autostart or switch form script to julia subprocess use C-c C-z. To
switch from process buffer to the most recent script buffer also use
C-c C-z. To associate a buffer with a different julia process press
C-c C-s.
Evaluation
To send chunks of code from your script use C-c C-c, C-M-x, C-RET etc.
To load the whole file: C-c C-l. See evaluating code section in ESS
manual. (tip: look up the documentation string of these commands with
for example C-h k C-c C-c)
Help
To access documentation for any help topic or object use C-c C-d C-d.
To call apropos: C-c C-d C-a. To look up for a topic in julia standard
library reference: C-c C-d C-r. To look up a topic in the julia
manual: C-c C-d m. To search julia website: C-c C-d C-w.
To see all help commands defined in ess-doc-map: C-c C-d C-h. See Help
section in ESS documentation.

running scheme from emacs

I'm a newbie to LISP.
I am attempting to invoke the scheme interpreter from within emacs (version 23 running on windows). I loaded the xscheme library by telling emacs to M-x load-library and then entering xscheme at the prompt in the minibuffer. The library loaded, and then I issued the M-x run-scheme command. (I realize that all this loading can be done from .emacs at startup, but I am not concerned with that at the moment.)
So far so good - the *scheme* buffer has been created, and now I'm hoping that I'm able to talk to the scheme interpreter.
However, when I try to evaluate something in that *scheme*buffer (e.g. (define shoe-size 14)), I get this Output file descriptor of scheme is closed message in the minibuffer.
Does anybody know how to fix this in emacs?
(Also, how does one set the major-mode as REPL in the *scheme* buffer?)
Thank you.
Try setting the scheme-program-name variable to the path to your Scheme interpreter. The major-mode of the scheme buffer is probably just comint and you cannot do much about it unless you switch to something more capable like Geiser - something that I'd recommend you do.
Add this line to your .emacs file:
(setq scheme-program-name "gsi")
(Replace "gsi" with the name of your Scheme interpreter.)
You can then start the interpreter with M-x run-scheme. You can evaluate pieces of code by using C-x C-e (to evaluate the sexp before the point) or with C-M-x to evaluate the sexp you're in right now. You can also load a file with C-c C-l.
I'll start by saying that I'm very new to programming, scheme and SICP, but I'm trying to work through the course and watch the lectures that are online.
I'm running emacs on Ubuntu 12.10 and I really wanted to get MIT scheme working in emacs instead of relying on Edwin.
The above tips didn't work for me, but here's the step-by-step instructions that did work:
Install emacs 24 from the Ubuntu Software Center (search "emacs" and install it!)
Open a terminal (ALT + CTRL + t)
Go to your home directory (cd ~)
Open the hidden file .emacs in gedit (gedit .emacs)
On the first line of the file, type exactly what's after the colon: (require 'xscheme)
Save the changes to .emacs
That's it!!!
You can now open .scm files in emacs and use commands like C-x C-e.

My guess is that it's just a known issue I still dunno how to sort that out (it's out of my current skills) but I got a macro that probably helps: just after writing the s-exp you can do Cc-Cz (it calls the geiser REPL) then C-spc, C-M-b, M-w, C-x-o, C-y and RET.
There are a variation (same, placed just after writing the s-exp): C-spc, C-M-b, M-w, C-c Cz, C-y and RET

How to force Org-mode to open a link in another frame?

In Org-mode it is possible to have links and top open links. As listed by http://orgmode.org/orgcard.txt in Org-mode C-u C-c C-o or mouse-3 forces links to open in another window. How can I do the corresponding for frames, that is, how can I force a link to open in another frame?
What I want is for C-c C-o to work as per default but C-u C-c C-o to force the link to be opened in another frame.
(For the distinction of windows and frames see http://www.gnu.org/software/emacs/manual/html_node/emacs/Frames.html.)
I am running Org-mode 7.6 in 23.3.1.
I just tested and you can get it to work by wrapping org-open-at-point in a (let ) as a custom function.
In this case I'm just prefixing the current org-link-frame-setup with your desired find-file-other-frame to ensure that if you use the command on another link type it will not fail.
(defun zin/org-open-other-frame ()
"Jump to bookmark in another frame. See `bookmark-jump' for more."
(interactive)
(let ((org-link-frame-setup (acons 'file 'find-file-other-frame org-link-frame-setup)))
(org-open-at-point)))
I suspect you will need to bind it to a key sequence other than C-u C-c C-o, unless Emacs will permit you to bind it to that sequence specifically.
Have a look at the variable org-link-frame-setup (M-x customize-variable RET org-link-frame-setup). The docstring should explain the approach.
I just tested this in a non-customized emacs:
emacs -q
GNU Emacs 24.0.92.1 (i386-mingw-nt5.1.2600) of 2011-11-30 on MARVIN
Org-mode version 7.7
When running C-c C-o and C-u C-c C-o on a link similar to the following:
file:~/Dropbox/org/test.org::*Test
I end up with a new frame being opened in both cases. C-u C-u C-c C-o opens the test.org file in my active emacsclient session. When changing the link to .../org/test.txt it still opens in a new frame, however it is unable to create the new file (I'm assuming I don't have .txt properly associated on my end, which is possible).
Testing with [mailto:test#test.org][test-mail]] also results in new frames by default.
Edit: The value for org-link-frame-setup is as follows (it is also the default since it is from emacs -q):
Its value is ((vm . vm-visit-folder-other-frame)
(gnus . org-gnus-no-new-news)
(file . find-file-other-window)
(wl . wl-other-frame))
