While I noted similarities and difference between Ruby and Python, as I was learning the basics here, here and here there is official document on the Ruby site. See this

Methods

• Ruby functions start with def just like python, but end with end keyword.
• splat operator (*) to destructure an array into a List. This is similar to Python splat operator

>>> x = [10, 20, 30]
>>> a, *b = x
>>> print(f'{a=}, {b=}')
a=10, b=[20, 30]

Python ☝️, Ruby 👇

>> first, *rest, last  = ["a", "b", "c", "d"]
=> ["a", "b", "c", "d"]
>> first
=> "a"
>> rest
=> ["b", "c"]
>> last
=> "d"
>>

But in Ruby, splat operator can also create an array.

>> q=*135
=> [135]
>> q
=> [135]

In the second scenario¹, it creates an array. I think this is useful for scenario where the method accepts either a single element or an array.

Then install lsd from here

• idiomatic(?) ruby loops use each like :

(1..5).each do |counter|
  puts "iteration #{counter}"
end

Although python like loop also work

for counter in 1..5
  puts "iteration #{counter}"
end

• array.each_with_index is like python’s enumerate

• Ruby seems to have multiple ways to do the same thing, as opposed to Python’s

There should be one– and preferably only one –obvious way to do it.

e.g. a.map do .. end, a.map { |el| e.something } and a.map(&:method)

There are multiple ways to install ruby on your machine.

Official recommendation is to use your OS’s package manager like apt, pacman or brew

If you are using a version manager, rvm (Ruby Version Manager) seems to be popular. But in the past, I started using asdf, so I’ve decided to stick with it. It is also mentioned (first in the list) on the official Installing Ruby page 😄

asdf plugin add ruby https://github.com/asdf-vm/asdf-ruby.git
asdf list all ruby
asdf install ruby latest

At the time of this writing 3.1.0 is the latest

I’ve meaning to learn Ruby for some time now.

Especially, when I dabbled from time to time in Elixir, I felt that knowing Ruby may be an advantage (since Elixir syntax similar to Ruby)

No one learns (I think) Ruby just for the language. They learn it so that they can use Ruby on Rails (RoR as popularly known) RoR, in case you don’t know, is the Web framework. Like Django in Python land. But there are a lot of web frameworks like Flask, Pyramid, FastAPI to name some.

After using tmux for a while, I realized that whenever I create new session locally, I end up opening same set of panes.

• One for work project (Sometimes more than one, but usually one)
• One for some kind of blog (I have three Hugo projects at this time)
• One misc. I start this in ~, I use this for running brew commands or standalone python session, or bin/doom sync (which I’ve been doing from inside doom emacs these days, so the last usecase has gone down)

Turns out I’m not the only one™️ with such use case.

As I mentioned in an earlier post, I’m trying to move to more text based workflows.

On that journey, I came across readable which creates a clean version of a webpage, just like Firefox Reader mode would do. But without Firefox.

Which means, you can read cleaner website from your terminal (if you want)

Read Firefox Reader mode in your Terminal

I had installed fzf some time ago. But default key ** for invoking fzf did not work with fzf.

Upon searching, I came across couple of options. Of those, I chose the one with active development.

As of this writing, the last commit was 11 days ago. Very active, I would say. 😄

Installation instruction said fisher install PatrickF1/fzf.fish but when tried, I got an error:

fisher: unknown flag or command "install"

🤔

I tried fisher add which seemed like closest option to install.

I’m leaning more and more towards text based workflow.

Earlier I enabled twittering-mode in Doom Emacs, and tweeted from Emacs. How 🆒 is that.

But that is when I realized that twitter has lots of URLs. If I visit a URL from my Twitter feed, it opens up in external browser by default.

I have two problems with that.

1. My flow gets disturbed.
2. The browser already has gazillion links open. Once I go there, I get distracted.

Opening links within emacs addresses both these (I think. Too early to comment)
