I created the sixth issue of the @shortrubynews #shortruby

Read the entire issue here: newsletter.shortruby.com/p/issue-6-2022

So here is what happened in #Ruby on Twitter last week
@shortrubynews @justalever shared a nice and simple piece of wisdom:
@shortrubynews @justalever @chalmagean shared some topics that a junior developer should focus on along with learning the language or framework:
Here are some other points that people shared in the conversation about what Rails juniors should learn

👇

·@inkyvoxel
· @bsilva96
· @RogersKonnor
· @rose_w
@rose_w @schwad_rb shared an example about undefining all instance variables but keeping a secret reference:
Here is a nice screenshot from that BlankSlate example:
source: github.com/jimweirich/bui…
@joeldrapper asked about how to simply serve static files on Ruby:
@joeldrapper @joeldrapper received a lot of good suggestions there:

• @olleolleolle shared Grip github.com/joeyespo/grip
• ruby -run -e httpd . -p 8000` were the most common answer and the simplest one in ruby
• @olleolleolle shared a link to github.com/ruby/ruby/blob…
@joeldrapper @olleolleolle @rubygems_status shared that they started to require MFA for the popular gems:
@joeldrapper @olleolleolle @rubygems_status @joemasilotti asked about how to send a notification when subscription status changes:
@joeldrapper @olleolleolle @rubygems_status @joemasilotti @joemasilotti received a nice reply from @palkan_tula about how to use pattern matching (see full gist here gist.github.com/palkan/ac1dcbd…):
@joeldrapper @olleolleolle @rubygems_status @joemasilotti @palkan_tula @nusco asked for resources to catch up with Ruby:
There are so many exciting replies to @nusco question that I don’t know what to pick. Here is one that I did not know so far discord.com/invite/stimulu… Discord channel shared by @julian_rubisch
@nusco @julian_rubisch @joemasilotti asked for recommendation about how abstract styles when working on Tailwind. It seems the main recommendation is to not use apply and use components.
@nusco @julian_rubisch @joemasilotti @jaredcwhite shared that he is working on a new project. More details are on The Spicy Web Discord server link to join discord.com/invite/CUuYVH7…
@nusco @julian_rubisch @joemasilotti @jaredcwhite @siaw23 shared about Enumerable having `first` but not `last:`
@nusco @julian_rubisch @joemasilotti @jaredcwhite @siaw23 @_byroot asked about GitHub Actions to trigger build when you push to a branch without opening a PR, but not to build twice:
There were suggested a couple of possible solutions for @_byroot question:

• This commit github.com/Shopify/identi… from Shopify/identity-cache

• This line github.com/yabeda-rb/yabe… from test.yml from yabeda-sidekiq

• The main.yml github.com/rubyapi/rubyap… from rubyapi
@_byroot @oceanicpanda shared that he is working on a list of Ruby engines.
@_byroot @oceanicpanda @OjedaAlef shared a piece of code adding methods on top of the Hash:
@_byroot @oceanicpanda @OjedaAlef @joeldrapper shared some code samples from gems he is maintaining:
@_byroot @oceanicpanda @OjedaAlef @joeldrapper @siaw23 shared a sample of using the Ruby … syntax:
@_byroot @oceanicpanda @OjedaAlef @joeldrapper @siaw23 @bhserna shared a sample code about using self for chaining methods:
@_byroot @oceanicpanda @OjedaAlef @joeldrapper @siaw23 @bhserna @hsbt shared they merged syntax_suggets and it is now part of Ruby standard library.

Read more about the discussion about merging this to Ruby here bugs.ruby-lang.org/issues/18159 and link to the Github PR here github.com/ruby/ruby/pull….
@_byroot @oceanicpanda @OjedaAlef @joeldrapper @siaw23 @bhserna @hsbt @faqndoE97 asked about how to build a design library
here are some suggestions received by @faqndoE97

👇

◦ separate gem recommended by @strzibnyj
◦ putting them all in a module by @joeldrapper
◦ UI module for generic and specific modules by @_swanson
@_swanson @joeldrapper shared a new update for the performance improvements in Phlex:
@_swanson @joeldrapper @joemasilotti shared a clean and nice sample code with View Components + class_names + polymorphic slots:
@_swanson @joeldrapper @joemasilotti @joelquen shared how `cycle` from Ruby works similarly with Haskell `cycle`:
@_swanson @joeldrapper @joemasilotti @joelquen @leenyburger shared that there might be a market for Rails themes:
on the same topic @joeldrapper shared a question about a market for GUI design interface for Rails:
Based on the replies from both these conversations from @joeldrapper and @leenyburger there seems to be a desire for more UI libraries/projects in the Ruby/Rails world.
@joeldrapper @leenyburger @adrianthedev asked a question about pains when working with UIs in Rails
Here is the most common pain points received by @adrianthedev when working with #ui in #rails:

• Missing UI libraries compatible with Rails

• Finding talented UI developers

• Working with ERB and partials
@adrianthedev @th1agofm created a poll about which debugger you use the most often in Ruby.
(open the quoted tweet to see the results, hint: pry is high)
It is worth reading the discussion this poll generated and also the following discussions from what Thiago shared after the poll closed:

- preference for debugging in REPL

- how devs are using debuggers .
@kkuchta asked a funny question:
Read the replies as there are interesting code examples offered there even if they break common wisdom 😆
@kkuchta @adrienpoly asked about recommendations on how to create a memo about what happened during the week:
He received two interesting replies:

• @afomera shared a good zsh function gist.github.com/afomera/44e2fd… that uses github cli to pull merged PRs

• @_swanson suggested using Linear
@afomera @_swanson @GregMolnar shared a good picture of the advantages of automated tests:
@afomera @_swanson @GregMolnar @dvassallo shared a view about skipping unit tests that triggered a lot of discussions about coding without tests:
Here is one interesting reply among many others from Cody Norman @cnorm35 to @dvassallo tweet about #unit #testing
Also related to testing, @postmodern_mod3 shared an excellent way to think about TDD/BDD that could help define when to stop:
@postmodern_mod3 @ejstembler shared a little code in Crystal about a Blacklist Handler that I think with just some small changes could be copied to Ruby:
@postmodern_mod3 @ejstembler @viebel asked a question about accepting extra fields in request payload that triggered a wide range of replies:
@postmodern_mod3 @ejstembler @viebel @keystonelemur shared why he thinks juniors are a critical path to healthy growth in engineering teams. Read the entire thread it is super good.
This edition was created with support from @adrianthedev from Avohq avohq.io/rails-admin (a friendly full-featured Rails admin panel), and from @jcsrb who recommended me some great tweets.
