LEM - What If Emacs Was Multithreaded

[@celestialbeing4767]

Emacs is underrated

[@mrdkyzmrdany8742]

Well, it may take some people some 20 years to stop hating it -- I've used emacs occasionally for slime or fuel REPL years back, and couldn't grasp how someone could use it for text editing. But some 1 or 2 years back I've bitten the bullet - mainly because I heard how magit and org-roam were great; and because I love extensible things you can modify at runtime; oh, and it got a JIT... What can I say, I'm now an emacs-infested zombie, I'm thinking about splitting my config into multiple files, I've read-up on stuff I'll need to connect to (friggin corporate) Exchange server from emacs. I'm toying with the idea to use emacs as a front-end for some simple app (just for admins to use) just for the laughs and bragging rights. Who knows when I'll start biting normies and infecting them too ;-)

[@NILOCOgov]

I’m really loving how diverse the text editor ecosystem is these days. So much cool stuff to try and get inspiration from.

[@jastern949]

It takes until 11:34 to get the caveat, "It isn't exactly stable yet" :-P heheh.. Thanks, Gavin, I enjoy your videos. lem was not as easy to get going on openSUSE/Tumbleweed, owing to TW using ncurses6 (not 5) and cl-charms' logic for that not being optimal. Got it going tho' with a little commenting help. Fun to play with tho'! Wow! a LISP-e editor Some Techie hints for future vids 1. A headset instead will not only improve audio signal but also prevent the sub-bass rumble in the microphone from the keyboard keypresses. 2. Some wax paper over the circular cam light will eliminate the 'zombie eyeballs'. Thank you again! Keep going!

[@ChaosTheory666]

I couldn't get it working at all on openSUSE Tumbleweed. Got as far as compiling it, but as soon as (lem:lem) is entered it all goes to ****. Really like the idea of a CL editor though.

[@sjatkins]

AWESOME! Something to play with as an emacs and lisp person.

[@oflameo8927]

If I was going to write a new text editor, it would have Evil mode key bindings by default and be a modal editor.

[@AndersJackson]

It is strange, I can't stand modal editors. Basically that started because of how editors worked back them (like ed). And then it added a text gui in front of ed. The next development was Emacs and getting away with the modal mode. But yes, we are different.

[@AndersJackson]

@@vlc-cosplayer vi/vim is a thin full screen character based layer on top of ed(1). Which is a line editor optimized for teletype/printer I/O. Yes, I have used them back when it was used as main terminal on a minicomputer (the one that would crush any limb of yours if you put the minicomputer on it, as it wheight about 500 kg or so). If you do not know what ed(1) is, please look up the man page. So by design vi/vim had to be designed to be modal. Even if it was sub optimala not a modern design. Emacs used then modern full screen designed, as it used moder CRT terminal, like VT-100, where you could control the promts position, erase lines etc. That was later used as model when xterm was designed. Yes, I have used them too That meant that Emacs could use control keys (Control combined with a character) as commands instead of input them into a buffer, like vi does. You OBVIOUSLY have absolutely no knowledge about how input works in Emacs, do you? Because then you would not make those assumptions. Emacs use programmable key maos to look up commands, and that has nothing to do with ESC in vi(1). Which are hard coded. There are nothing like vi:s edit mode, input mode and visual mode. That is vi modal levels. Yes, as Emacs has programmable keybindings, you could change the default keybindings to one that simulate vi keybindings and modes. Actyally, as Emacs is fully programmable, introspective, live programmable, it isn't rocket science to do that. Actually there are several keybindings that do that, in different levels of success. Most common is evil-mode. Still, most Emacs non modal keyboard bindings are still available if one want to use the abomination 😉 like evil-mode. And again, vi doesn't have programming language support, with an REPL to the inner parts of vi. Vim has some extension languages, as an after thought. Not by design, like Emacs. So yes, vi/vim might be usable for your need. But please, don't make the mistake to think you now know Emacs, because you obviously doesn't. And please don't make the mistake and say that vi or even vim us as expandable as Emacs. Because then where is an Org mode extension delivered by default in vim? And where are the Emacs keybindigs mode for vim, by default? As Emacs do have Org mode and Evil-mode by default. Yes, if you have an easy to access extension for those, please inform me about them. Because if there are a Emacs bindings in vim, I might try them. And by the way, default keybindings in Bash are Emacs keybindings. Try C-e and C-a or C-r in Bash. Have a nice day.

[@AndersJackson]

@@vlc-cosplayer and seriously? C-o i instead of C-a? And vim users say they are into vim for the efficient key bindings?

[@AndersJackson]

Thanks, LEM was interesting, but I think I stay with Emacs. :-)

[@stevenlitvintchouk3131]

At my advanced age, I'm too set in my ways. GNU Emacs for one.

[@CaribouDataScience]

Say what tiling wm are you using?

[@mishaerementchouk]

Have you looked at emacs-ng? It’s a technology expanded emacs. I didn’t use for a while because of issues with the resolution on hidpi monitors but the performance boost for me was impressive. I often have to deal with long org files with a lot of math and for such files the performance wowed me.

[@AndersJackson]

Lates Emacs has compile on demand, which should make Emacs run faster.

[@mishaerementchouk]

@@AndersJackson It does run faster. However, emacs-ng has a few features that make it even faster. At least, this is so for my workflow: Emacs hangs on some of my org files with a lot of formulas, so I cannot have the "latexpreview" option in the header. Emacs-ng has no trouble opening these files right away. If not for a bunch of oddities (for one, formulas are rendered with artifacts, which is a dealbreaker for me), quite likely I'd be using emacs-ng.

[@JungleLibrary]

Emacs ng's Dev put it on hiatus in May 22: "The problem is that there are not enough experienced people maintaining the project. I was hoping we could encourage more people to help when the project provides new features that users are interested in. However we obviously didn't get to that point. I would gladly give it another try, but I'm not able to fix the more complicated issues myself or implement cool new stuff(at least not at a level that would make a difference). Maybe some users will continue the work that was started. I would join them ;)"

[@mishaerementchouk]

@@JungleLibrary That's a pity. I didn't understand how they were pulling this off as maintaining such a project requires quite a bit of work. I presumed they had some strong momentum going. Apparently, it didn't reach the critical mass. Too bad, it was an interesting project.

[@JungleLibrary]

@@mishaerementchouk if it's working for you, they are at least still merging the latest changes to Emacs, but if you've been dealing with issues in the hope that it'll improve, I wouldn't count on it.

[@aleccox7383]

I like the wallpaper you have, any link to it or an update your wallpaper git repo?

[@lamprospitsillou6325]

Could you add the github link in the description? Nice vid!

[@GavinFreeborn]

Just added it. Thanks for the reminder

[@connorcreegan]

this is pretty interesting, definitely gonna fool around with this at some point. too bad it's only cli, as i use emacs gui pretty frequently for in-line images. otherwise i'd be sold, for sure.

[@mrdkyzmrdany8742]

Lem has SDL back-end (don't try the terminal one on windows, it's butt-ugly -- if you can get it to work)

[@yash1152]

4:47 redo only got added recently in emacs... ohw, can same be expected for the readline library for bash cli?

[@yash1152]

9:43 it will be ctrl + \ if it were to happen it seems

[@miricaley4988]

Is it got a GUI interface, or is it still in development and will merge in the near future?

[@marcinmiszczyk]

looks nice

[@kitcarson2034]

There is very few contents about this interesing editor, do you still use it?

[@noblesavage149]

👍

[@thelambdafunction]

There is a substantial mistake in this video: LEM does not plan to implement Emacs in CLisp. It just so happens that uses the -macs approach (that is "editing macros"), but does not plan to support and/or replace Emacs. Its aim is to be the ideal IDE for CLisp, perhaps to replace Emacs in the famous Portacle project

[@pavelxbushmakin7252]

Do you know good editors writing by Scheme(Guile)? I want Guile EMacs, but it doesn’t maintained

[@GavinFreeborn]

I've seen a few but non seem to have gotten much farther than a proof of concept

[@ivanicguildmember2844]

Awesome video as always. Could you please tell me the name of the terminal font you are using here.

[@GavinFreeborn]

PregmattaPro

[@GeorgijTovarsen]

Never heard of it. I was expecting something like Climacs but it seems nobody is using it anymore.

[@spookyconnolly6072]

LEM is highly like the Climacs project but renamed like 5 times and the code altered to be closer to modern programming standards, which includes awful punnery

[@defaultxr]

There is a new incarnation of Climacs called Second-Climacs. I don't think it's ready for general use yet, but development is active.

[@LambdaJack]

curses is a sign of quality.

[@geoffreyvanwyk4588]

Please make a video of Lem 2.0.

[@محمدفرج-ث7ذ3د]

Bon for emacs it will awesome review

[@Mythologos]

I love your channel but it would *really* improve your work if you used easier to read fonts with fewer crazy colors and magnified the text more. It's very hard to follow and you seem to change all that between videos. Are you familiar with SystemCrafters? He keeps an Emacs in a VM for doing tutorials, so it's always the same - and he keeps a uniform look from video to video.

[@cory1111]

I’m actually surprised that someone who loves functional languages is running Arch instead of Nix or Guix

[@GavinFreeborn]

I know right! Big reason is many of the projects I play with and contribute to don't seem like they would work well with Nix.

[@abc249]

@@GavinFreeborn If you ever try nixos, it would be cool, if you make a video on it? There are no videos about the configuration of emacs or vim on nixos, at least I haven't come across those.

[@peterzimmermann55]

@@abc249 configuration on NixOS (and guix as far as ik) works the same way that it does on any other system. Nix is a package manager, and NixOS is built around it. There might be a way to configure it in home manager, which i agree would be great for a video but you aren’t forced to use home manager. Personally I install all of my addons with home manager and use a standard elisp config file to actually write my configuration

[@florianfelix8295]

Damn I’ve been hoping for sth like that in guile :‘(

[@AndreasWilfer]

There used to exist one, but I don't know where it's hosted, if at all anymore..

[@florianfelix8295]

@@AndreasWilfer you can look on the guile mailing list. I think it is a branch of guile itself (guile-elisp). If you mean guile-eMacs. But it needs to be ported to guile3

[@defaultxr]

@@AndreasWilfer Perhaps you're thinking of Zem? "Extensible Emacs-like text editor with Guile"
