Dialog from emacsclientw.exe must be dismissed (was RE: Bestpractices for launching Emacs on Windows 7/8)

Ludwig, Mark — 2013-06-19T18:17:25

This bug still exists.  The first time emacsclientw.exe
attempts to find a running Emacs daemon after restarting
Windows, it pops up a dialog that must be manually
dismissed.  The dialog says:

c:\<...>\emacsclientw.exe: connect: No connection could be
made because the target machine actively refused it.

This behavior has been there for a long time, and would seem
easy to fix.  Doesn't anyone else hit this?

Thanks,
Mark Ludwig

How to get info about narrowing in effect?

Thorsten Jolitz — 2013-06-19T16:50:01

Hi List, 

in a program, I would like to find out about a buffer:

1. is narrowing is active?

2. what are the boundaries of the narrowed region (so to say point-min
and point-max of the narrowed region)?

but I don't find related functions in the Elisp manual. 
How can I do that?

How to get ido-find-file to open DOIs in browser (like URLs)?

Marius Hofert — 2013-06-19T07:37:54

Hi,

I often use C-x C-f (ido-find-file) to open links/URLs in the browser.
I am wondering how one could get the same behavior when the point is
on DOIs (digital object identifier). This is of the form
10.1016/j.csda.2008.05.019, for example, and should open
http://dx.doi.org/10.1016/j.csda.2008.05.019. There are some regular
expressions posted on stackoverflow to match (a larger number) of
DOIs.

Cheers,

Marius

[Bug] in newcomment.el

Thorsten Jolitz — 2013-06-18T17:08:11

Hi List,

postscript printing in emacs

Rami A — 2013-06-19T23:46:09

Hi all,

I have aliased pw to be:
mp -l -s "\!*" <\!* | lp
which prints buffers in a nice format 2 pages on each printed page in landscape.
But I have to do that from a shell.

How do I incorporate this functionality in emacs so I could choose a region or simply print the whole buffer using "postscript print from buffer/region" from inside emacs?

Finding a file by name that has been indexed in etags

C K Kashyap — 2013-06-18T13:42:18

Hi,
In vim, I can quickly jump to a file by typing its partial name and it
lists all the files that match that pattern and are in the tags file.
I could not find an equivalent in emacs.

help needed setting up etags on Windows

C K Kashyap — 2013-06-18T12:29:09

Hi folks,

Could someone please help me get started with setting up etags for a large
C++ source base? I'd like to use emacs on cygwin. I assume etags is the
right tool for source indexing with emacs.

It´s Emacs 24.2.1 and it´s the master branch version of el-get

dired listg & dired-sort-menu.el

Harry Putnam — 2013-06-17T13:24:21

   Running 
   Emacs 24.0.92.1 on Debian (testing)

Just tinkering with the sorting in dired and ran across Francis J
Wright's 'dired-sort-menu.el' (and menu+)... The following site shows
the menu that is produced:

  http://www.emacswiki.org/emacs/DiredSortMenu

But when I load the library and press 'M-x dired-sort-dialogue' I get
a less extensive menu and wondered if this is a result of the library
being quite old (or possibly changes in the gnu 'ls' command..) 

  ( dired-sort-menu.el,v 1.26 2001-07-26 21:22:48+01 )

compared to the emacs version I'm running or if
I've done something to cause this.

If it matters I tried with and without dired-x.

Extending 'emacs-lisp-mode' Disables 'auto-complete' for It

Haroogan — 2013-06-15T17:26:01

Hello,

I've extended emacs-lisp-mode with my elisp-mode in order to provide 
more syntax highlighting. Relevant excerpt:

...

(define-derived-mode elisp-mode
   emacs-lisp-mode
   "?L"
   "A major mode for Emacs Lisp.
\\{elisp-mode-keymap}"
   (set 'font-lock-defaults '((elisp-mode-font-lock-keywords)))
   (set-syntax-table elisp-mode-syntax-table)
   (use-local-map elisp-mode-keymap)
   (run-hooks 'emacs-lisp-mode-hook); Tried `run-mode-hooks` as well...
   (run-mode-hooks 'elisp-mode-hook))

(provide 'elisp)

Then I have:

(add-hook 'emacs-lisp-mode-hook 'ac-emacs-lisp-mode-setup)

And of course:

(require 'elisp)

(add-to-list
  'auto-mode-alist
  '("\\.el" . elisp-mode))

Now the problem is that auto-completion doesn't work in elisp-mode.
I have no clue why.
As soon as I disable elisp-mode and return to the emacs-lisp-mode it 
works just fine.
I've also tried:

(add-hook 'elisp-mode-hook 'ac-emacs-lisp-mode-setup)

and without luck...

Any help is appreciated.
Thanks.

Moving between headers in message-mode

Emanuel Berg — 2013-06-15T04:00:44

Hello all. I wrote this tonight. The purpose is defined in the
docstring. It is supposed to be used in message-mode. I haven't
done much testing but it seems to work. If you have any
suggestions how to make it better, please tell me. Cheers.

either on the same line as the present point,
or the next header below.
If the field has a string, put point to the string's right;
if the field is empty, put point so that typing will set the header,
without any prior cursor movement.
If you move from a header which has data, that data is expanded if
found to be an `abbrev-mode' abbreviation (possibly setup in
~/.mailrc), without need for a whitespace.
If there are no headers left, `message-goto-body';
if already in the body, goto the topmost header.
If BACK, do the same, only in reverse direction."

What does "merge" in ido.el mean?

Xue Fuqiao — 2013-06-15T13:10:38

I'm reading ido.el, and I have a small question.

I saw the word (or term) "merge" in in `ido-ignore-directories-merge',
`ido-merge-ftp-work-directories',
`ido-auto-merge-work-directories-length', and some other
symbols/docstrings.

I don't know what this term means here (what does it merge?).  I want
to read the sources in detial but don't know where to start.  And I
have also searched "emacs ido merge" and "ftp merge" on web but
there's nothing promising.  Can anyone point me in the right
direction?

Best regards, Xue Fuqiao.

Invalid font name

Joon Ro — 2013-06-14T14:33:20

Hi,

I am using GNU Emacs 24.3.1 (x86_64-suse-linux-gnu, GTK+ Version 3.6.4). I
have custom font Inconsolata-g in my ~/.fonts folder, and I have set it as
the Monospace font in ~/.config/fontconfig/fonts.conf.

It works well except Emacs is giving me error: Invalid font name,
-unknown-Inconsolata-g-normal-normal-normal-*-15-*-*-*-m-0-iso10646-1 at
launch.

If I change monospace font (to a DejaVu Sans Mono, for example), then Emacs
launch without problem, but when I do M-x set-default-font, and select
-unknown-Inconsolata-g-normal-normal-normal-*-*-*-*-*-m-0-iso10646-1, I
also get Invalid font name:
"-unknown-Inconsolata-g-normal-normal-normal-*-*-*-*-*-m-0-iso10646-1",
even though I inputted it through auto-completion.

Best,

Joon

resolve rename-buffer conflicts

Hongxu Chen — 2013-06-14T01:54:04

Hi,

  I have followed some tips to rename file(and the corresponding buffer
  name) like this below:

,----------[ rename-this-file ]
|   (defun rename-this-file (new-name)
|   "Renames both current buffer and file it's visiting to NEW-NAME."
|   (interactive "sNew name: ")
|   (let ((name (buffer-name))
|         (filename (buffer-file-name)))
|     (unless filename
|       (error "Buffer '%s' is not visiting a file!" name))
|     (if (get-buffer new-name)
|         (message "A buffer named '%s' already exists!" new-name)
|       (progn
|         (rename-file filename new-name t)
|         (rename-buffer new-name t)
|         (set-visited-file-name new-name)
|         (set-buffer-modified-p nil)))))
`----------

Since there might be a buffer name conflict I am using `(rename-buffer
new-name t)' inside this function instead(according to the docstrings,
if the last argument is non-nil it is supposed to generate a new buffer
name when there is a conflict). However it DOESN'T work at all. It
reports like below:

    A buffer named 'test.cpp' already exists!

But it works fine when invoking `rename-buffer' interactively like `C-u
M-x rename-buffer'.

So Why it fails for the snippet above?
(I also use uniquify.el but I don't believe it is a problem since it
defines an advice `rename-buffer-uniquify')

Number of Windows in Current Frame

Haroogan — 2013-06-13T17:20:47

Hello,

How do I determine the number of windows in the current frame?
I'm aware of current-window-configuration, however I couldn't find how 
to retrieve any information from it.
In particular how do I get the number of windows from it?
Or is there another way to do it?

Thanks.

matching parenthesis and guillemets

henry atts — 2013-06-13T12:34:30

In text-mode when typing guillemts to indicate direct speech I always
get this message about non matching parenthesis:

`No matching parenthesis found'

Yes, I could disable it with `blink-matching-paren' or set
`show-paren-mode' to nil. But because this affects emacs' global
behaviour this is not what I want.

Why in the first place does emacs think he has to tell me about matching
or not matching guillemets - they are no braquets actually.
And in fact emacs treats the guillemets the wrong way up, the above
message is displayed on the opening guillemet (») and not on a single
closing one («) with a missing match.
