I want to be notified when someone addresses me on irc. But some reason I can't achieve that.
I tried to set the list erc-modules to include notifications like so:
(require 'erc)
(add-to-list 'erc-modules 'notifications)
(erc-update-modules)
It was giving me:
Symbol's value as variable is void: notifications
So then I simply did
M-x customize option
erc-modules
There I clicked the "notifications" options. And the following was saved to my .emacs file:
(custom-set-variables
...
'(erc-modules (quote (autojoin button completion fill irccontrols list log match menu move-to-prompt netsplit networks noncommands notifications readonly ring stamp track)))
...
)
But I still have no notifications. By the way, I left the first code block, from above, in .emacs file. Its still at the very bottom of the .emacs file, after everything else.
So my question is how do I set erc to notify me when someone is addressing a message at me?
Thanks in advance for your kind help and time.
Jenia.
According to the manual ( https://www.gnu.org/software/emacs/manual/html_node/erc/Modules.html ), one method would be to: (1) set erc-modules manually; and, (2) then call erc-update-modules.
My interpretation of that is as follows:
(require 'erc)
(setq erc-modules '(
autojoin
button
completion
fill
irccontrols
list
log
match
menu
move-to-prompt
netsplit
networks
noncommands
notifications
readonly
ring
stamp
track))
(erc-update-modules)
Your other erc settings should be removed.
I have a similar error: ‘notifications’ is not a known ERC module.
Lawlist's solution doesn't work for me.
Adding (require 'erc-desktop-notifications) solved my problem.

I am using many different org mode files for various projects, and I rev them by adding the date to the filename eg filename-2020-09-17.org. I realize I could use version control but in this case that is not possible, due to needing to share the file with others who are not using VC.
I would like the Agenda to always show just the items for the current file/buffer.
When I save eg the file with filename-2020-09-16.org to filename-2020-09-17.org, then the agenda still shows the old file name unless I remove it from the agenda file list and add the new file.
I realize that I can use C-c a < a but I am lazy and would rather not have to type S-, each time to get the <.
I looked at
Agenda view of the current buffer
And the OP says the solution was simple but he/she/they did not provide the solution - at least I don't see it and I tried the posted code but it no works.
I also found https://www.reddit.com/r/orgmode/comments/bxwovd/agenda_for_current_buffer/ but that did not seem to meet my need.
Specifically I would like to put something in .emacs so that this would apply to all files all the time.
I also looked into a keystroke macro programs but this does not seem ideal.
Any help is appreciated.
Thanks ahead of time.
Here's a simple function to do what you want, but there is no error checking to make sure e.g. that you are invoking it from a buffer that is visiting an Org mode file. The idea is that you set the org-agenda-files list to contain just the file which the buffer is visiting and then you call the regular org-agenda function. Binding the modified function to the C-c a key may or may not be what you want to do, but you can try and decide for yourself:
(defun org-agenda-current-buffer ()
(interactive)
(let ((org-agenda-files (list (buffer-file-name (current-buffer)))))
(org-agenda)))
(define-key global-map (kbd "C-c a") #'org-agenda-current-buffer)
I have written an org-mode model of a Mac keyboard which uses links to identify elisp functions associated with a given key and optional modifier. It occurred to me that I could use the org-mode external elisp link type so that when I click on the text, the code will execute to describe the key binding (describe-function). And it works, but with a nasty side effect that I get prompted with an ugly dialog to approve executing the code. I totally understand that this is default behavior but I am hoping this behavior can be easily overridden by an org-mode configuration setting so that "yes" is effectively always selected. Perhaps the answer is to create a custom protocol.
I think what you need to set are:
;; enable prompt-free code running
(setq org-confirm-babel-evaluate nil ;; for running code blocks
org-confirm-elisp-link-function nil ;; for elisp links
org-confirm-shell-link-function nil) ;; for shell links
I'm trying to get doremi working in emacs. Specifically, at this stage, to allow me to quickly scroll through a condensed list of color-themes and see each theme as I go through it. For this I would use the 'M-x doremi-color-themes+' command.
What I've done:
Installed color-themes (successfull)
Installed doremi.el, doremi-cmd.el, ring+.el and added
(add-to-list 'loadpath "~/elisp/themes")
(add-to-list 'loadpath "~/elisp/doremi/")
(require 'color-theme)
(color-theme-initialize)
(color-theme-classic)
;; create a list of color themes to scroll through using 'doremi-cmd
(setq my-color-themes (list 'color-theme-classic
'color-theme-retro-green
'color-theme-gray30
'color-theme-subtle-hacker
'color-theme-jonadabian-slate))
(require 'doremi)
(require 'doremi-cmd)
(require 'ring+)
to the .emacs file.
What emacs does:
When I type the comand 'M-x doremi-color-themes+' into the mini-buffer it seems to accept that I've given it a valid command and tells me to use the and arrow keys to move through the list. But when I do that all that happens is the cursor moves up and down in the active window. No changing of color-themes.
Being somewhat new to emacs (and especially customising it) I'm sure I have missed a step or put something in the wrong place. Perhaps there's some sort of (setq 'bla-bla-bla (...)) I need to do?
Sorry for your trouble. Please state your Emacs version (M-x emacs-version), and your version of color-theme.el.
You do not need to require library ring+.el if you use Emacs 23 or later (its code was included in GnuEmacs 23.)
You do not need to use (color-theme-initialize) or (color-theme-classic). The former is done automatically by doremi-color-themes+.
Try starting from emacs -Q (i.e., no init file, ~/.emacs), to be sure there is no interference from stuff in your init file.
Your variable my-color-themes is not referenced anywhere. Instead of defining that variable, just customize user option doremi-color-themes. (Or leave its value nil, which means that all color themes will be cycled through.)
Feel free to contact me by email if you continue to have a problem. Or continue here, if you prefer.
[Just to be sure: you are using color-theme.el, right? There is a lot of confusion out there between Emacs "custom themes" and color themes. Do Re Mi supports both, but they are different critters.]
After a bit for back and forth with #Drew we found a solution to the problem.
It turned out the major problem was that I was using emacs in 'terminal mode' rather than as a GUI application. Bare in mind I'm using a mac.
In the context of Terminal, my arrow keys send escape sequences and so doremi cannot read the event as intended. So it just escapes and applies the message to the active buffer.
There is an answer.
By adding the following lines to my .emacs file (or whatever your init file for emacs is) I was able to redirect doremi to use two other keys. ie. not the up and down arrows.
(setq doremi-down-keys '(?n))
(setq doremi-up-keys '(?p))
Doing this tells doremi to use 'n' as the down key and 'p' as the up key. And all works just fine.
Because I am only new to the world of programming and computing I may often use incorrect terminology. If this is the case please let me know and I will edit accordingly for clarity and consistency.
So I'm relatively new in trying to customize emacs. But I really need to customize is asap. Tabs are a pain in emacs as they are two spaces, and the text is all messed up when it is opened with any other editor after that.
Currently, I only have few lines in my ~/emacs.d/init.el file:
(setq load-path (concat (getenv "HOME") "/.emacs.d/"))
(set-scroll-bar-mode 'right)
(require 'linum)
(global-linum-mode t)
I get an error while starting up emacs:
Loading encoded-kb...done
An error has occurred while loading `/Users/mycomp/.emacs.d/init.el':
Symbol's function definition is void: set-scroll-bar-mode
To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with
the `--debug-init' option to view a complete error backtrace.
I tried srtating it with the --debug-init option, but my lisp knowledge is not enough to help me figure out what's wrong. Any help on how to get this working or redirecting me to some GOOD tutorials on editing init.el files will be really helpful (yes i did google tutorials on editing the initialization file, but every one of them was terrible).
I'm assuming my code for getting line numbers on the left is also wrong. Could someone please help me with this? Thanks a lot.
I think this line may be the problem:
(setq load-path (concat (getenv "HOME") "/.emacs.d/"))
First of all, I don't think this is required to load ~/emacs.d/init.el. Secondly, if you do want to add a directory to your load-path, you should probably be doing it like this instead:
(add-to-list 'load-path "~/.emacs.d/")
This code adds the directory to the load-path, your code just clobbers it with the single directory.
Use 'M-x apropos' and 'M-x customize-apropos'. For now, those will make your life much easier when you want to customize things.
For instance, to customize things to do with scrolling, 'M-x customize-apropos RET scroll RET' will give you a list of all things that you can customize that have 'scroll' in them. You can look around and find the things that you want by searching the buffer. If you find a particular thing that you want, there's usually a group that it belongs to. You can click on that, and just customize those particular values. Make sure you save the settings.
It might take you a while to figure out what things are called. If you've got an idea, try the apropos search. If that doesn't turn up anything, google can probably sort it out for you.
For now, don't worry about hacking the elisp. This method will write values to your startup file (probably the .emacs?) and you can look and check the syntax later if you're really interested. I customize most of my stuff this way; I only bother actually modifying the file by hand when I'm trying to write my own hooks or functions.
This question may be a duplicate of this question, but I can't get the following to work properly in my emacs.
I am trying to enter minor mode mlint-mode whenever I enter major mode matlab-mode (both modes available at their SourceForge page). I have the following in my .emacs file:
(add-hook 'matlab-mode-hook
(function (lambda()
(mlint-mode))))
which looks like the answer to the question I linked above. When opening a .m file, I get the following error:
File mode specification error: (void-function mlint-mode)
Could someone please assist in helping me write the correct hook to enter mlint-mode when I open a .m file? FWIW, I'm running emacs 23.1.50.1.
I think the correct name is mlint-minor-mode. Also, remember to ensure that all matlab stuff is known by Emacs, this can be done using:
(require 'matlab-load)
As a side note, it is typically a bad idea to use lambda functions in hooks. If you inspect the value of the hook you will see a lot of unrelated things. Also, if you modify your lambda expression and re-add it, both the old and the new version will be on the hook.
Instead, you can do something like:
(defun my-matlab-hook ()
(mlint-minor-mode 1))
(add-hook 'matlab-mode-hook 'my-matlab-hook)
The "1" is ensures that mlint mode is turned on or stay on if enabled earlier.
