Theme in picture is ef-summer. I love these so much. They're a breath of fresh air among the other techy-cyber-hacker themes, yknow?

The other ones seem less active than this one.

It's gotten too much. I think 1100 is a bit too much custom ELisp code. I also got to a point where my customization started interfering with Doom's core modules, yielded weird errors from time to time. I found out that Doom's defaults are actually beautiful and idk guys I feel refreshed, I'm ready now to get shit done, I can now actually work™️. I have offloaded the annoyances to Henrik.

2024 year of bankruptcy let's go

Hi there,

I want to try emacs in my terminal-based workflow. I use tiling window manager (i3 - qtile) in ubuntu

so super+number changes the workspace. When starting an emacs with -nw, changing workspaces

super+[1, 2, 3, etc] inserts "IOIOIO" characters in my buffer.

Any ideas?

I am a newbie to emacs and Linux in general (started my linux journey 2 months ago) and want to learn emacs. Does anyone have good ressources to learn emacs as a beginner? Also should I use a distro like doom Emacs or should I do it from scratch

What's the best practice to have your custom elisp natively compiled, along with external packages?

So far I've only succeeded by doing the following:

• Move my custom elisp to a new file (emacs-lib.el) which starts with (provide 'emacs-lib)

• Manually run emacs-lisp-native-compile-and-load while visiting that file

• Change my init file to load the library:

  (setq elisp-dir "~/config/elisp") (add-to-list 'load-path elisp-dir) (require 'emacs-lib)

After restarting Emacs, I've checked that many of my custom functions are indeed native-compiled.

It would be nice if I could have my init file take care of compiling the library when missing or outdated. Even better if I didn't need the separate file, but that's no big deal.

I wrote a library that lets you cycle through the available themes in Emacs. F10 and shift-F10 keys will cycle forward and backward through the themes. The theme name is printed for reference.

https://github.com/tsengf/theme-cycle

Installation
Download theme-cycle.el into ~/.emacs.d.

Add the following to your Emacs configuration

(add-to-list 'load-path (expand-file-name "~/.emacs.d)
(require 'theme-cycle)
;; Load as many themes as you are interested in exploring.
(use-package doom-themes)
(use-package ef-themes)
(use-package modus-themes)
(use-package solarized-themes)

To Use

Use F10 to cycle forward through the themes. Use shift-F10 to cycle backward through the themes.

I have a setup that sort of gives what I'm looking for, but Emacs complains that I'm not doing it right.

I have a large number of org-mode appointments that depend on the date of Easter. They are currently in the form of diary sexp, but I don't really care what form they're in; what I'm really trying to find is a general solution to "When today is X days before Easter, show arbitrary message 'X' in the org agenda. When today is Y days after Easter, show arbitrary message 'Y' in the org agenda." (In all of my cases, Easter means "the Easter within the current calendar year".)

Emacs elegantly figures out the correct date for Easter, but Emacs also has a hard-coded list of Christian holidays that aren't useful to me. Instead of a new hard-coded list of holidays, I'm looking to make arbitrary and changeable use of the Easter calculation - compared to today - without showing any holidays at all.

TLDR: I really want to learn emacs, getting frustrated with the basics and seeking help. Can't install use-package on my mac installation of emacs.

I've been using neovim for awhile but have been increasingly frustrated with not being able to understand how things work when they break down. Hoping to learn emacs for fun and maybe to even replace/improve my nvim workflows.

Things went well at first. I followed the tutorial and got used to some basic navigation as well as window and buffer navigation. I LOVE being able to `C-h` for functions, keys, and variables.

I decided it was time to start trying to configure things and installing packages. I'm not patient enough to watch 10 hours of system crafters videos and didn't really want to buy Mastering Emacs, so I decided to do some googling and figure things out myself. I came across a guide with some basic starting points and was feeling good about things until I got to this part: https://medium.com/@suvratapte/configuring-emacs-from-scratch-use-package-c30382297877

I am completely unable to install use-package and that feels pretty defeating. I followed the instructions and the package was not found. I tried `package-refresh-contents` and found use-package-hydra use-package-chords and use-package-el-get. Can't seem to find use-package.

After some googling I thought it might be that my mac-homebrew-installed version of emacs was missing TLS support, so I deleted it, pulled the emacs-mac repo, and installed it with no issues. Started up my new install and had to navigate the fact that my alt key was no longer bound and my command key was magically mapped to meta which I don't want. It was really frustrating to run into this and have no idea how to C-h my way out of it. I managed to map alt to meta and map command to super, but not I can't command-c any more which is an annoyance.

On top of this, I still can't install use-package, the exact same thing happens. I deleted the part of my config that sets up melpa and used the instructions from their site. I confirmed using eww that I have TLS support working. I tried a number of commands from reddit and elsewhere and have not made any progress. I feel like I'm back in my vim config hopelessly adding lines to my config until it's not broken.

Primarily I need help passing this hurdle so that I can try and set things up myself. It would also be super nice to understand why these things have been failing and how I can better use resources to fix issues like this in the future.

Hello Everyone,
This is my first post every on reddit I hope I don't get RTFM ed.
Problem: Until about a week ago I used to use a doom emacs config I got off of the internet with some modifications just for references in latex. this week I finally decided to code my own literate gnu emacs config but there is one feature I am sorely missing. In the image attached in a org-mode document there is syntax highliting for latex code outside of src_code blocks I want that but I don't know how to get it into my new config. Further information can be provided on request.

Hi there, I'm trying to brush off my emacs and Orgmode since it's been years. I'm hitting a few snags and am also wondering about current standards since there has been many updates.

My goal:

Use Orgmode to customise my emacs and init files while using the Dropbox directory. I would also like to use a custom named init file so it's like eckoinit.el instead of init.el (For easier recognition and modification).

Overall, I'd like to sync and use emacs from different computers using the same configs.

I know one of my current snags is I can't remember how to tell emacs from Orgmode to use a differently named init file. I feel like this should be an obvious answer that I should have found by now and I feel silly.

Thanks for your time!

Hello Emacs Community!,

​

I'm a long time Emacs user, right now using the Doom framework and, I recently took a look at the power Nix, specifically the devenv.sh project. I wonder if someone is using it in some manner. As it being quite powerful and allowing having separate development environments.

​

Are there any packages for this?, and if not, how complicated would it to be to for example, once entering a project, Emacs gets all of its PATHs (languages like NodeJS and other niceties) so that little by little, the project can be replicated and used completely with devenv and Emacs without having to installing anything globally.

​

Thank you, I would love to hear your workflows!, just wanting to be sure I'm getting the best of the best in my environment, I will be coding in Javascript, Angular and so on.

This Emacs config's built from scratch by this humble Elisp noob. I want it to be minimal and plain. Love some feedback!

I have been trying to get dap-mode for c++ to work. Below is my config related to dap-mode

(use-package dap-mode
  :after lsp-mode
  :commands dap-debug
  :hook ((c++-mode python-mode . dap-ui-mode) (python-mode . dap-mode))
  :config
  (dap-auto-configure-mode t)

  (setq dap-python-debugger 'debugpy)
  (require 'dap-python)

  (require 'dap-gdb-lldb)
  (require 'dap-lldb)
  (setq dap-lldb-debug-program "/usr/bin/lldb-vscode")
;;; ask user for executable to debug if not specified explicitly (c++)
  (setq dap-lldb-debugged-program-function (lambda () (read-file-name "Select file to debug.")))

  ;;; default debug template for (c++)
  (dap-register-debug-template
   "C++ LLDB dap"
   (list :type "lldb-vscode"
         :cwd nil
         :args nil
         :request "launch"
         :program nil))
;; (defun dap-python--pyenv-executable-find (command)
;;   (with-venv (executable-find "python")))

(add-hook 'dap-stopped-hook
	  (lambda (arg) (call-interactively #'dap-hydra)))

(defun dap-debug-create-or-edit-json-template ()
    "Edit the C++ debugging configuration or create + edit if none exists yet."
    (interactive)
    (let ((filename (concat (lsp-workspace-root) "/launch.json"))
	  (default "~/.config/emacs/default-launch.json"))
      (unless (file-exists-p filename)
	(copy-file default filename))
      (find-file-existing filename))))

The problem I am facing currently is that every time i run

dap-debug

while the file is open i get prompted for executable and when i select the candidate, I get the error

Wrong type argument: stringp, nil

From what I learned we get the above error when a function get a nil value while expecting a string but I don't understand why the function will get a nil value when i selected the correct executable with appropriate compiler flags.

I would appreciate any help in the matter.

Hey everyone, quite a while ago I created the Naga theme; it's also on MELPA. I used it for a long time (and I'm still using it in the evenings), but I'm not totally happy with it. I'd like to spend a little more time on it, changing some colors, updating the slightly outdated screenshots in the readme and so on. While I'm at it, I could have a look at packages that don't work well with it as well. I have some other ideas for themes, and an improved naga would also give me a better base to work from for these.

I'd be glad if some of you could maybe test-drive it and give me feedback, especially if it perhaps breaks or looks plain bad with some packages you use.

The main idea of the theme was to get a "more modern retro green" theme, with high contrast, but a non-standard foreground color -- green in this case.

Thanks in advance!
