Write beautiful shell scripts with Gum! [Terminal Velocity 4]

[@charmcli]

We're so flattered! Thanks for the awesome video on Gum

8:05 Bash has support for arrays, rather than doing tr, you can use branches=($(git branch)) This will take branches as an array Then use for for branch in {branches[@]}; do echo "the branch is $branch"; done

[@alessandroferrari2166]

it's such a pleasure seeing you going through your thinking process and coding things out

[@darkarie]

fyi you can use `gum filter --no-limit` and use the fuzzy finder too. Then you would use Tab instead of Space for the multi selection :)

[@nickolaizein7465]

Nice! I think it would be helpfull in my next bash task! Thank you!

[@davidh.4944]

Just a reminder, while it may not look as fancy, bash does have the built-in _select_ operator for simple menu choices. select branch in "${branches[@]}"; do echo "$branch" break done Other comments below detail how to get the input into an array. But you could also just use an unquoted $(git branch) in this case, and rely on IFS word splitting to break up the list.

[@davidh.4944]

Also, any time you start to call up tr, think about using parameter substitution instead. Ignoring the array stuff for now: branches=$(git branch) echo "${branches// /$' '}" And to handle unset parameters, you can simply set a default value. limit=${1:-1}

Pleasantly surprised with this content!! Seriously cool and had never heard about this before!

[@andrew-burgess]

Thanks! BTW, what do you think of the audio on this one? Made some changes to my mic setup and my post processing!

[@mmmikem]

@@andrew-burgess it's super!! Could listen to this all day 👍🏻 On a slightly unrelated note, your pacing is really good too! I feel like you took just the right amount of time to explain what you were doing, that even though I haven't touched bash in 3 years, I was able to follow and learn a ton!

[@andrew-burgess]

@@mmmikem That means a lot to me! Thanks so much, glad to have you watching :)

[@i_do_stuff]

very cool and useful

[@blank001]

Gum's use case looks somewhat similar to that of dmenu and rofi, will definitely give this a try by updating some of my existing dmenu scripts to gum

[@andrew-burgess]

That’s cool, I’ve only heard of dmenu and rofi in the context of Linux app launchers. Are you referring yo something else?

[@blank001]

@@andrew-burgess you are in for a treat, dmenu and rofi has so many wide use cases other than just app launching. I'll add some examples here, when I am on my PC

@@leo848 it can work as app launcher, clipboard manager, emoji picker, network manager, logout manager, maybe more, But I use it for these only.

How do you to always make interesting topics video.

[@vitormelo22]

This is amazing tool.

[@digitaldisruptlabs]

Great videos, I have looking for something to level up my scripts, and looks like this a very good and fun option. Btw, your keyboard sounds pretty good. What's the model? :) Cheers!

[@andrew-burgess]

Thanks! I’m using the Drop ALT keyboard.

[@alirezashayegan8260]

its so good

[@user-kn4wt]

what are the options for doing this in python? I've seen rich but it doesn't seem quite as powerful as this or bubbletea.

[@kshitijnigam]

great, I am too dumb to ask how its predicting and giving suggestions in vim? any plugins?

[@andrew-burgess]

Yep! Check out shaky.sh/tools/

Not a fan of how the echo data stays on screen.

красивый мужик, знает баш и работает в виме, надо его срочно замуж выдавать. если он показал всё что делает гам то получается он умеет форматировать текст и создавать чекбоксы. ахуеть конечно функционал. за собой он наверное тащит ncurses а что же еще. честно говоря, если мне захочется пользоваться псевдографическим интерфейсом, я наверное сам руками его напишу потому что это весело, но гам тоже установлю, потому что мне тоже будет нужен ncurses. кто будет пользовааться гамом кроме самой чарм и тех кто его рекламирует? наверное никто, в этом наверное и смысл этих программ, это симулякры НО вот я например посомтрел это видео налюбовался на двойной подбородок этого красавицы мужчины и теперь мне тоже хочется начать писать на баш. баш вообще крутой язык, совершенно неинтуитивный, но некоторые решения там сделаны так как я бы сам сделал если бы изобретал собственный баш. лаконичный язык.

[@samuelbanya]

Rewriting Magit huh? Just use Doom Emacs

[@paulthexton7483]

Great video. Gum does look really nice, I've done this sort of stuff before using the old ncurses based dialog command and it's pretty painful. However: "Bash doesn't really have great support for lists or arrays" ... not _entirely_ true, here's another way to skin that particular spud... #!/bin/bash get_branches() { echo "branch_one branch_two branch_three" } read -r -a branches
