Introduction to EShell

[@MMABeijing]

Ur literate DevOps video really blew my mind 8 years ago

[@ceving865]

Had the same experience. When I tried it first, it just confused me and I ignored it for a few years. But now some few years later (and also pained by Windows) I start loving it.

[@aqua0077]

Never knew eshell could be so cool. Thanks a lot for the demo and the note!

[@jwwiegley]

Good stuff! I learned a few new tricks here too. :)

[@howardabrams1]

Hahahaha.... nice one, Captain John!

[@howardabrams1]

Hahaha. You're the best!

[@kickbuttowsk2i]

The man himself..huge respect

[@byronschlemmer]

Thanks Howard for sharing your insights and the video to boot! Really enjoyed it.

[@Granateable]

The video is 42 minutes long. A coincidence? I think not.

[@howardabrams1]

:-D

[@robertkielty5094]

Checks towel.

[@BartoszDuszel]

Awesome, as always. Thanks for sharing!

[@evanmiller4665]

Howard. I love your emacs videos. Please keep making them. I'm currently working on the question of whether I want to use Eshell (with Tmux?) inside Emacs or Emacs inside of Tmux for my personal development environment. This video is helping me with that decision--I think.

[@TheMickmccarthy]

Another quality Howard Abrams video 👍🏻

[@lassekliemann6251]

I switched to EShell as my main shell about a year or so. Not going back. However, when I tramp to a remote host, I find the filesystem structure confusing, since / still refers to my local filesystem. This has many advantages, obviously, but not being 100% aware of it all the time, it may lead to horrible mistakes. So I still resort to Emacs terminal mode with Bash inside a lot when I work with remote hosts.

[@cranknlesdesires]

Could you make a function to return to the hosts root?

[@richardfrangie3518]

Thanks Howard.

[@mariownyou]

What Colortheme do you use. It is so nice

[@garycheng12]

Welcome back!

[@Maverick5x]

How is "term" working fine with your zsh theme... could you please point out if you have any special configs for this?

[@howardabrams1]

I'm not using zsh anymore, but in the video, I just ran the Lisp expression: `(term "ipython")` Is that what you meant?

[@walid7885]

I tried to run a command with " | less" in eshell and it didn't quite work. It opened another buffer in a different that says the function "less" stopped. It looks like eshell does not handle well piping.

[@paschikshehu7988]

new video when

[@romanticjo8522]

Hello Howard, @24:37 you walk through eshell-favorites.el and it looks like you are able to highlight part of the sexp while the rest takes the comment face properties. How are you able to do that? I would love to be able to do the same when I walk groups over code. I love the intro video!

[@howardabrams1]

Check out the fancy-narrow project at github.com/Malabarba/fancy-narrow

[@zhaohengzhang832]

May I also ask how did you quickly navigate to the dimmed parts and use that part as the new narrowing region?

[@purgatoriprytania5382]

Just wondering how you coaxed org-mode into hiding markup characters (e.g., /, *, =, etc.)?

[@howardabrams1]

Set the variable, `org-hide-emphasis-markers` to `t`, as in: (setq org-hide-emphasis-markers t)

[@SweetJustLikeAMango]

What font are you using in this video?

[@nalidbass]

He is using Adobe source code pro.

[@panxie5223]

This guy types so fast😳

[@shfxpl]

This is demo-it, a mode that helps you create demos or presentations. You can hear when he actually types. github.com/howardabrams/demo-it

[@richardfrangie3518]

and without seeing

[@alanjones2770]

How do you type caps letters and non-alphabetical symbols so fast?

[@pharmokan]

wow clojure, python, bash, lisp, ruby, is there any language you don't know?

[@mariusandersons]

how to clear eshell screen

[@samweerasinghe3320]

hey Howard, great audio quality. what kind of headset/microphone do you use?

[@ryanleemartin7758]

I still don't get it. I really like Emacs and I use it more and more every day but I don't get why I'd want this over a proper terminal emulator. sure Bash language is awful but there are other options. Piping output to a buffer.. seems like that could be interesting to mess with. I dunno. lol.

[@howardabrams1]

I get it. It is weird. Eshell is really a craftable Lisp REPL, which intrigues some and alienates other. If you are still curious, you might want to see my follow-up to this presentation I did a EmacsConf 2022: emacsconf.org/2022/talks/eshell/

[@ryanleemartin7758]

@@howardabrams1 Thanks! I'm definitely still interested. It just hasn't clicked with me yet!

[@nickbernstein]

So you are probably thinking of the shell as bash, or bashish shells like zsh. When I first started with Unix, I was doing a lot of c coding, so I got used to "thinking in c" - as a consequence, I used "csh" or "the c shell", because it used c style syntax instead of sh/bash/ksh syntax. I imagine if you spend a ton of time doing elisp, this would have a similar benefit. It would be nice if they could get terminal emulation working natively though; I do like my htop.

[@ChaiFeng]

`echo "$IN" | cut -c 1-3` is same as `${IN:0:3}` more simple: if [[ "$IN" = abc* ]]; then # blabla fi

[@howardabrams1]

Ah yeah, if you're using that fancy new shell called bash. 😉
