今回話す人/Speaker 相生ゆら/Yla Aioi @Little_Rubyist @Little-Rubyist I am interested in RBS
and Rubocop. 2023/02~ talk about today
When was your first RubyKaigi? Job change
Last year was my first time there! (That was a
lot of fun.) Job change
btw, we had a RubyMusicMixin by Pixiv last year. It
will be on the day3 again. Job change
I was drunk at the time and said to a
Rubyist I had just met... Job change
“I've been wanting to work at BOOKWALKER for 6 months~
>_<” Job change
The Rubyist Job change
smoothly Job change
handed me a BOOKWALKER business card. Job change
The Rubyist is an employee of the company I wanted
to join! Job change
me when I receive twitter DM right after RubyKaigi
casual interview →apply for the job opening →joined the company
Job change
While it is often said that speaking about your dreams
to others can make them come true, I did NOT anticipate such a rapid pace of events Job change
unexpected things like this tend to happen at RubyKaigi Job
change
So, I successfully got into the company I wanted to
join 🎉 Job change
Thank you RubyKaigi Thank you RubyMusicMixin
It appears to end here, but there's a bit more
to come
Since I've made the effort to join the company, I
want to deliver results About RuboCop
What I can do even if I don't understand the
project well enough. About RuboCop
A little refactoring (so I’m a “little” Rubyist) About RuboCop
For example, replacing the short one-line `let` with `{...}` About
RuboCop
About RuboCop
About RuboCop An array of `let` defined in rubocop-rspec
About RuboCop Converting a long one-line `let` to `do...end`
About RuboCop Short one-line `let` is replaced with `{...}`
About RuboCop
About RuboCop AST matcher
About RuboCop Converting a long one-line `let` to `do...end`
About RuboCop Short one-line `let` is replaced with `{...}`
It became a “little” more convenient
Simple Cops like this are easier to work on
We can write them even without fully understanding the project's
content, which is a great advantage
There are probably many people in this venue who are
new to Ruby or recent graduates.
Let's try improving the environment starting with the easy stuff
👍
Ruby community is SO good! :) Summary
I am happy to have Ruby as my first programming
language
I love Rubyists and Ruby community
Happy coding with Ruby and community!
