Emacs

Hello,

the most powerful thing in elisp is program as data but what does it mean how can I run data as a program. I was confused too but here is what I found.

First I tried this:

(setq x '(+ 1 3))
(x)

basically setting the value of x as a list. now x is set to some code but when I try to run x as function using (x) syntax we get this error *** Eval error *** Symbol’s function definition is void: x. It tried to look for function in x but couldn't find it. then how can I run the code that I stored in a variable? how to evaluate it? we need a built-in function eval.

If we run this code it works and outputs 4:

(setq x '(+ 1 3))
(eval x)

so yeah, it is how you can evaluate a code stored in a variable. feel free to correct me if there is another way to achieve it :)

Hi! I'd like to share a package of mine that was recently made available on MELPA.

Disproject is a package for GNU Emacs that provides integration with project.el and allows for dispatching various project-related commands via Transient menus.

It is similar to (and inspired by) the function project-switch-project, but also attempts to improve on its feature set in addition to the use of Transient. Projectile users may also find similarities to projectile-commander.

Some notable features include (but may not be limited to):

• Auto-detecting the current project when starting the menu.
• Switching between active projects (i.e. only those with open buffers).
• Defining custom per-project suffixes like compilation commands to show in the menu (see disproject-custom-suffixes).
• An option to prefer displaying buffers to another window when executing commands.
• When available, integration with: envrc; magit; magit-todos; mise.el.
• A set of customizable variables to substitute some commands in the menu (see Customization).

The latest, 29.x, version of Emacs. Whenever I drap&drop an image into a note, it'll open an image in a new buffer. An image won't get embedded or attached onto a note. Why not? Hasn't d&d functionality been added since several versions ago, natively?

How to embed or attach an image onto a note? Preferably, a) by Drap&Drop b) without any third-party package

announce the release of Magit version 4.0.

One of the best things to happen to EMACS!

More information can be found on in the release notes.

Hello,

I am an vim user and I am used to the vim way of doing things. I started tinkering with emacs some time ago and enjoying it since because of the elisp. however I find the default keybinding kinda weird and it's hard to get used to it. we can't even vi" or ci" in emacs. also emacs doesn't have inbuilt multi cursor support.

I really want to use emacs but these things are holding me back :(

Emacs 29.3 is an emergency bugfix release intended to fix several security vulnerabilities described below.

** Arbitrary Lisp code is no longer evaluated as part of turning on Org mode. This is for security reasons, to avoid evaluating malicious Lisp code.

** New buffer-local variable 'untrusted-content'. When this is non-nil, Lisp programs should treat buffer contents with extra caution.

** Gnus now treats inline MIME contents as untrusted. To get back previous insecure behavior, 'untrusted-content' should be reset to nil in the buffer.

** LaTeX preview is now by default disabled for email attachments. To get back previous insecure behavior, set the variable 'org--latex-preview-when-risky' to a non-nil value.

** Org mode now considers contents of remote files to be untrusted. Remote files are recognized by calling 'file-remote-p'.
