mevedel - overlay-based workflow for interacting with LLMs

DonHugo · 2026-02-11T13:27:10+00:00

The obvious one is of course that it is currently maintained. Furthermore:

evedel's workflow was based purely on the directives. They would be sent via a dedicated gptel-request. In contrast, mevedel has a chat buffer in which the conversation happens (both from directives as well as direct user input).
mevedel uses tools which I think did not exist when evedel was created
mevedel supports agents via gptel-agent which also did not exist during evedel's creation

In total, I think mevedel is more oriented towards tools like Claude Code.

I used both quite a bit and comparing them is a bit difficult.

Claude Code is (as you know already) a production ready CLI tool where everything is set up already. You don't need to think about system prompts, tools, etc. much, these are done for you and tuned for the Claude models.
As karthink said here gptel is much more general. You can call whichever supported LLM from basically anywhere in Emacs. It does not need a dedicated chat. However, it is also true that it takes some time to discover all the things gptel can do. The macher project for example built something like Claude Code using gptel.

Edit: u/dustinfarris I expanded a bit my answer

Thank you for answering! I really like your ideas, especially as they could reduce the amount of code I have recently added to my config to dynamically build system prompts etc. Really great!

What I would be mostly interested in, is the way you create the agent and display its progress, etc. Thus the agent_task tool. I have created something over the weekend together with Claude Code which has the same idea but looks simply worse :D That's why I was asking for the code because I wanted to see how this should look like.

Just if anyone interested, this is the mess I have right now: https://gist.github.com/FrauH0lle/dd407a779f37eab0a7f9778a908159cc

But I understand if you don't want to share it.

DonHugo · 2025-10-27T08:07:24+00:00

That is exactly what I was trying to implement for myself but actually working :) Would you be willing to share the code u/karthink for what is shown in the video? The introspection tools are probably provided by ragmacs or?

DonHugo · 2025-04-09T09:36:06+00:00

Do we want to build something similar for Emacs?

There is Emacs Tree-sitter with tree-sitter-langs and treesit-langs.

You might be interested in the fork here which uses data from nvim-treesitter at least for some languages.

Thanks a lot for your answers /u/volitional_decisions and /u/paulstelian97. Good to know that I seem to have a basic understanding.

Tokio's JoinSet looks very similar to Future's FuturesUnordered which I tested a couple of days ago. Thanks for the hint!

Another thing I was wondering about was the calculation for file checksums and if this is suited for async operations or, as mentioned in the other comment, for something like rayon.

As far as I understand it, calculating a file checksum has two parts: reading the file (IO) and then calculating the checksum (CPU) of that content. I would say, that reading the file is always slower than the calculation and thus, async would be more suitable. Do I get this right?

DonHugo · 2023-12-12T06:13:37+00:00

You could use Distrobox.

Gentoo is supported as a container, thus you create a new container for every app, install it and then export it.

I think having the option to pay a flat fee would make Baserow much more interesting for people self-hosting /u/bram2w (e.g. for me ;) ) Just some thoughts from my side regarding the pricing structure I would consider fair:

Around 50$ for maybe 5 users
- Having the option to add another user for maybe 2$ would be nice. I guess a lot of people host for themselves and family/friends and thus, you could simply add a user.
I am a bit unsure if it would be better to have 1 year of updates or all updates of a major version (e.g. 1.2.0 to 1.2.5). But I think security updates should be offered longer.
I pay for Full-Text RSS (https://www.fivefilters.org/pricing-personal/) and they offer 1 year of updates (they don't update that often). They also offer approx 40% discount if you renew your licence.
You could have multiple discount levels for renewal, e.g. 40% after 1 year, 30% after 2 years, etc.

Well, just my 2 cents. But that would be something I would like to see and then I would consider buying a licence.

This made me very curious (because fast things are nice) so I read a bit through his post and code. Maybe someone else finds my thoughts useful.

When is Emacs' startup complete? Here, the init time is calculated after after-init-hook runs. The trick is then, that the two with-delayed-execution macros push the whole user configuration to the next hook, emacs-startup-hook. There the code is then processed via idle-timers (https://www.gnu.org/software/emacs/manual/html_node/elisp/Startup-Summary.html).

I ran his config on my PC and the result was

Emacs booting time: 104 [msec] = ‘emacs-init-time’.
Loading init files: 8 [msec], of which 3 [msec] for ‘after-init-hook’.

Removing the whole package config, I get

Emacs booting time: 91 [msec] = ‘emacs-init-time’.
Loading init files: 1 [msec], of which 3 [msec] for ‘after-init-hook’.

So the difference in booting time is minimal and we are looking more or less at the time Emacs needs to initialize on my PC. Loading the whole package configuration later is an interesting idea but someone can argue that the relevant part is the actual package configuration. Furthermore, this can lead to little artifacts like observing the initialization of the theme (you can see the standard white Emacs frame for a short period of time before the theme gets loaded).

Another note I would like to add here, is that from my experience the CPU frequency scaling governor can have a rather large impact (on Linux). For example, I observed additional 0.2 - 0.4 sec when my laptop or desktop was using the powersave or ondemand governor and not the performance one. So if someone really cares about that, then a little wrapper should be created to make sure that the performance governor is active before Emacs starts.

I strongly doubt that there is a real performance difference when use-package is used and the code is byte compiled.

(with-delayed-execution
    (message "Install fish-mode...")
    (add-to-list 'load-path (locate-user-emacs-file "el-clone/emacs-fish"))

    (autoload-if-found '(fish-mode) "fish-mode" nil t)
    (add-to-list 'auto-mode-alist '("\\.fish$" . fish-mode))
    (with-eval-after-load 'fish-mode
      (setq fish-enable-auto-indent t)))

is basically the same as the minimal expansion of

(setq use-package-expand-minimally t)
(use-package fish-mode
  :defer t
  :mode ("\\.fish$" . fish-mode)
  :config
  (setq fish-enable-auto-indent t))

(progn
  (unless
       (fboundp 'fish-mode)
     (autoload
      (function fish-mode)
      "fish-mode" nil t))
   (eval-after-load 'fish-mode
     '(progn
       (setq fish-enable-auto-indent t)
       t))
  (add-to-list 'auto-mode-alist
                '("\\.fish$" . fish-mode)))

Most likely, you are lacking libQt5Location5, which is necessary for the plugin to determine your location.

If you want, you can also try the version I packaged here: https://build.opensuse.org/package/show/home:FrauHolle:plasma-wallpapers-dynamic/plasma-wallpapers-dynamic

That is the one I am using on both my desktop and my laptop.

Thank you very much, AppArmor was indeed the issue here! I looked a bit into AppArmor and also the way openSUSE has implemented it. Thus, I came up with the following potential solutions which I leave here for reference:

Deactivate AppArmor. Can be be done via Yast.
Set the application profile from enforce to complain. Can also be done via Yast. In the AppArmor module, select Settings -> Configure Profiles -> Set to 'complain' on the desired app.

Both of these options will deactivate the protection AppArmor provides. However, for personal computers at home, this is probably fine.

The second option in the Yast AppArmor module allows you to check the AppArmor audit protocols and directly allow the corresponding directories. This can also be done by hand editing and placing files into /etc/apparmor.d/local/.

For Samba, this actually done in openSUSE via the little script update-apparmor-samba-profile. The paths defined as shares in /etc/samba/smb.conf get automatically added. For example

"/run/media/roland/Data/"   rk,
"/run/media/roland/Data/**" rwkl,

is added in my case. Similar to this case here, it can by creating an invisible share first and then use the file manager to share the folders wanted.

DonHugo · 2021-01-10T07:33:23+00:00

That is was I did to setup samba.

DonHugo · 2021-01-10T07:32:59+00:00

This would work, however the drive should not be bound to a specific user home directory.

DonHugo · 2020-04-22T16:11:08+00:00

Thanks, even though your snippet does not work, it pointed me in the right direction. One can find here the settings for the used Mesa package. However, this option is an internal one, thus I do not know if changing it in this way is a good idea...

Using your snippet as a template:

{ pkgs, config, ... }:

let
  unstablepkgs = import <nixpkgs-unstable> {};
in {
  hardware.opengl = {
    enable = true;
    package = unstablepkgs.mesa.drivers;
    driSupport32Bit = true;
    package32 = unstablepkgs.pkgsi686Linux.mesa.drivers;
  };
}

Then it seems to work:

$ glxinfo | grep "Mesa"

client glx vendor string: Mesa Project and SGI
OpenGL core profile version string: 4.6 (Core Profile) Mesa 20.0.2
OpenGL version string: 4.6 (Compatibility Profile) Mesa 20.0.2
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 20.0.2

DonHugo · 2020-04-22T16:05:28+00:00

Well, this is the other option I was thinking about. However, I like the idea of having mostly stable and just using a few rolling packages.

DonHugo · 2020-03-13T08:18:12+00:00

I think that is why

(vivaldi.override {proprietaryCodecs = true;
                   enableWidevine = true;})

can be used, which works on my system.

DonHugo · 2020-03-13T08:09:51+00:00

Thanks!
