emacs29 treesit support
I'm trying emacs29 treesit support for C/C++, reading around I configure the builtin package as follows:
(use-package treesit
:ensure nil ;; emacs built-in
:preface
(defun my/setup-install-grammars ()
"Install Tree-sitter grammars if they are absent."
(interactive)
(dolist (grammar

(add-to-list 'treesit-language-source-alist grammar)
(unless (treesit-language-available-p (car grammar))
(treesit-install-language-grammar (car grammar)))))
(dolist (mapping '((c-mode . c-ts-mode)
(c++-mode . c++-ts-mode)))
(add-to-list 'major-mode-remap-alist mapping))
:config
(my/setup-install-grammars)
(setq treesit-font-lock-level 4))
treesit), this is how I configured C/C++:(use-package cc-mode

Having to quit(), start the interpreter and import every time I edit the code?
Hello!
I'm new to emacs and so far it's really easy to use and it's very effective. One annoying thing however is that every time I edit the code I'm writing, I have to quit() in the interpreter, close the window (Ctrl-x + 0), restart the interpreter (Ctrl-c + Ctrl-p) and reimport the code.
I edit the code and then just write "import *script*" but the changes don't appear unless I do it as mentioned above.
Even if I just quit(), I can't just (Ctrl-c + Ctrl-p) again because I have to close the buffer for it to start again.
Is it supposed to be like this? Or am I doing something wrong?
Thanks in advance!

Emacs Module Critique
I started using emacs this week and have been interested in using org. I went for a modular config and attached my very simple org module below.
From what I've read so far there isn't necessarily a "correct" way to configure emacs but I'm asking for a critique on anything in this module. Whether that be my use of use-package (especially as I've found its documentation somewhat unclear), my custom function, code style, or anything. I would appreciate any two cents or bits of wisdom as I begin my journey configuring emacs.

how to make lsp and eglot way faster like neovim?
through little bit of research i have found a way to make Emacs faster with lsp and eglot none of this are my code i just found it from browsing on reddit
(fset #'jsonrpc--log-event #'ignore) remove laggy typing it probably reduces chatty json from lsp to eglot i guess
(setq eglot-events-buffer-size 0) disabling event logging in eglot
(setq eglot-sync-connect nil) disabling elgot freeze the UI for up to 3s when you open file maybe large one
install gcmh package to increase the gc value when necessary and decrease it. nice package btw
(add-hook 'focus-out-hook 'garbage-collect) optional, if you don't want to use gcmh package
(setq eglot-connect-timeout nil) optional "my code actually"
set this values on company package or
(setq company-idle-delay 0) how long to wait for company mode to wait after it got completion obviously you don't want to wait so just set it to 0
(setq company-minimum-prefix-length 1) how many characters you want to type before popping up the completion UI obviously 1 right
if there is anything that i am missing pls let me know guys, am new to Emacs i want to learn from you all. i would love to see your config too to learn how to configure mine too

ob-ledger-convert: Convert anything to ledger using Babel
After struggling for years to manage my personal finances, found ledger/hledger. My goal is to find my yearly expense so that I can make FIRE plan. Ledger is great, but required to create transactions in ledger. Struggled with parsing bank/card pdfs, manually creating entries and nothing worked. Eventually realized that I can just copy the text from pdf into emacs and then format it using emacs macros. Then next task was to convert the transaction lines into ledger entries. This gave birth to `ob-ledger-convert` or `ob-lc` to provide `lc` src blocks in the org mode which when executed convert the given transactions into ledger format. It does need parsers and I have provided some of the parsers used by me in the `ob-lc` module. New parsers can be added easily.
This post is to share the enthusiasm of the emacs being such a fascinating machine which lets you do anything you want and also to get the feedback from the community on the package.
The sample org file provided in the repo provides a gist of how to use the module.

interested in emacs as a whole, but have no idea what it can really do
hey! I'm a newly-converted Linux user (dabbled with it a bunch but it finally feels to have really stuck), and I've always used vim as a default console editor, which has been good, feels pretty fast, though all i really do is edit config files with it.
i hear a ton about emacs, and the lengths to which people take it, but i don't actually know what it can do
basically all i know is that it's a very configurable text editor, but from what I've heard, that description doesn't really do it justice.
so basically, tldr, what makes emacs so good? why do people like it so much?

Treemacs all the icons
Hi everybody ! I'd like to use all the icons with treemacs but I can't figure how to do it. I tried (straight-use-package 'treemacs-all-the-icons) I use straight package manager, but it doesn't work. I tried (treemacs-load-theme "all-the-icons") but didn't work either.
Any ideas ?

Creating regions within a buffer
To preface - I started using emacs about 2 years ago, and this is my first real foray into trying to make something of my own.
I've been trying for a while to find an emacs startpage that I find useful. I work mostly out of org files, so I have no use for the scratch buffer, the default is fine but a little lacking in functionality (for me at least) and I tried the dashboard.el package (which is what inspired me to try to make my own).
My goal is to take a single buffer and divide it into multiple regions, so that, for example, the top half could display a calendar (I use calfw, so I had intended to show the one week view here) and the bottom half could be divided into left and right. (I had wanted to show magit-list-repos and org-agenda here). I didn't see any existing packages that seem to allow for this, though I absolutely could have missed something.
This could obviously be changed, my thought was that it could function similarly to how you define elements in html, and if I get it working could be pretty dynamic and flexible. I'll settle for some hardcoded regions though, if it means I could get something to work.
This presents some challenges. I toyed with simply copying the output of the respective commands, and I got close to making that work before I realized that, while that would solve my problem, it sort of defeated the point of what I had undertaken in the first place. Next, I tried overlays but to be honest I couldn't make that work at all. I started looking into it based on the name ("overlay" just sounded like it would do what I wanted, but once I read more into what it did I wasn't entirely sure).
That lead me to make this post - I don't really know what else to try, or even if an idea like this is feasible within emacs. I'm attaching a sketch that hopefully illustrates what I would like this to do...
I'd appreciate any input!
Also - yes, I realize that I can split windows to accomplish the layout that I'm looking for. The reason I didn't use that is because I want to use this as my screen that shows when I open emacs. If I have three windows automatically open with their own buffers, I would have to close 2 of them just to focus on one window - which is a little annoying.

How do I improve my development experience in Emacs?
I've been using Emacs for 4 months now, and seriously, and I don't want to go back to VSCode because of the fact that I can do everything in it (notes, task management, and programming; I also love org-mode). Unfortunately, my development experience has been okay-ish with Emacs. I have installed lsp along with corfu for completions (and web-mode for ReactJS) but the completions are not as good as VSCode. They are quite slow too. Here's the link to my config file. How can I improve the completions? I would also like it to highlight unused imports (flycheck isn't doing it, idk why). Just this much would suffice :) I don't need anything else from a code-editor (although Emacs is so much more than that).

How do you load a package without ;;;autoloads header? (doom emacs)
There is a really niche, but simple package for elfeed that adds system notifications: https://github.com/flocks/elfeed-notifier/blob/master/elfeed-notifier.el
However loading it by default with straight package manager doesn't work:
(package! elfeed-notifier
:recipe (:host github :repo "flocks/elfeed-notifier"))
Nothing happens, no function or variables are available.
Does anyone know what's the standard procedure for loading such packages? I assume that it has something to do with use-package?

Is anyone using elfeed? I'm trying to add a hook to send desktop notification when articles become available.
I was wondering if anyone is familiar enough with elfeed's codebase to advise where would be any good place to hook when new articles become available to send a desktop notification with a truncated title of the articles?
Also I've noticed that emacs users... kind of don't use notifications (org-agenda, elfeed)? Do you all guys just have photographic memory, see the future, read minds to not need to keep up with any schedule?

Linking Latex installation to emacs
I'm using emacs to edit my latex documents. I have the auctex emacs package installed, as well as latex-preview-pane.
I would like to use the siunitx latex package.
I installed the package doing: sudo apt -y install texlive-science
When I compile my document using directly latex: pdflatex mydoc.tex
it works, but when I'm within emacs, the latex-preview-pane package cannot compile my document.
I guess I have to tell emacs and auctex where to find the packages I installed when I installed texlive-science.
How can I solve this ?
PS : I know that the error in latex-preview-pane comes from the \usepackage[siunitx], because if I comment this line, it works perfectly.

A diff based approach to saving files
I was saving files by C-x C-s save-buffer command. I do some changes to files and some time after I have done a complete change, I spam a C-x C-s.
But sometimes I can change unrelated parts of a buffer unconciously. Sometimes I delete some part of a buffer, sometimes I copy a huge part of another buffer into this buffer and have a very long extra parts that are hidden under an org heading.
So the problem is I sometimes change the file in some unwanted way. Most of the time those goes unnoticed and long time I see some inconsistencies with the file itself and how the it should be. I see that the file does not have integrity. This is a bad experience mostly. So I wanted to be able track contents of every save operation I make to the files.
I also don't use auto-save-visited-mode which saves buffers automatically. That may result in also me making unconcious changes to a file and then it goes unnoticed.
So I began to look into diff modes. I saw the diff-buffer-with-file command, which indeed turned out to be useful.
​
​
​
​
I think that it is a good practice to diff buffers before saving. So I don't use C-x C-s but now I do this:
​
C-x C-SPC first to view the diff then use
`SPC' and `S-SPC' keys in diff buffer to
scroll through the diff buffer.
​
After viewing the diff I use `C-SPC' key in diff buffer to save
the main buffer and quit diff window or use `c' or `x' keys
to just quit diff window without saving the main file.
​
This way I have a more secure and concious way to save files
knowing what am i writing into the file.
​
;; we use diff-mode-map and diff-buffer-with-file below, so this is needed
(require 'diff-mode)
;; use this key to diff current buffer with its file
;; beware that going to the diff window by using
;; other-window command is a bit of a hack, replace it
;; if you have a more resilient and certain way.
(define-key global-map
(kbd "C-x C-SPC")
(lambda nil "Diff current buffer with its file and go to its diff window"
(interactive) (diff-buffer-with-file) (other-window 1)))
(define-key diff-mode-map
(kbd "C-SPC")
(lambda ()
"Quit the diff window and save the main buffer."
(interactive)
(quit-window)
(save-buffer)
))
;; q already quits the diff window, but because x and c are
;; near the SPC key, we prefer those keys to quit the diff window
(define-key diff-mode-map (kbd "x") 'quit-window)
(define-key diff-mode-map (kbd "c") 'quit-window)
I hope this helps

maccalfw: A calfw interface for MacOS's Calendar app
​
maccalfw
This is a project born by personal need and mostly for personal use and very much still work in progress, so use at your own discretion. I am still testing it as I had to customize large parts of calfw and calfw-blocks to my liking (working on the interface for modifying and adding events now).
Bug reports and possible improvements are welcome.
​
A bit of background: I was trying to find ways to view and modify my calendars from within Emacs which lead me down the rabbit hole of figuring out calendar clients for my Google Calendar, my Apple calendar and my work Office365 calendar. Clients for Office365 are particularly annoying with the new Oauth2 system; an app has to be trusted by Microsoft which pretty much means that all open source clients are unusable unless one has admin control over the Azure environment.
After some pointless struggle, I decided to just rely on my local MacOS calendar app to handle all the authentication and to sync my calendars. I wrote a simple interface in Swift which can be imported in Emacs and then used to feed events into calfw.
