Is Li Haoyi libs standard throught scala useres?
To dive into the lihaoyi ecosystem, I recommend the book https://www.handsonscala.com/ by lihaoyi himself.
-
Contrary to popular belief, Scala is actually a quite small and simple language
I recommend people go through Hands-on Scala, by Li Haoyi, a fantastic developer in the Scala community.

How is Databricks' style guide viewed nowadays?
If you like Li Haoyi's style of Scala, his book is a good place to start (it's longer than just a Style guide, of course): https://www.handsonscala.com/

Algorithms and Data Structures in Scala;
is there a great resource, book or library on classic Algorithms and Data Structures in Scala, e.g. similar in scope and quality to Sedgewick Algorithms in Java https://algs4.cs.princeton.edu/home/ I found a very helpful section on algorithms implementation in /u/lihaoyi superb Hand-On Scala Programming book , but unfortunately it's only a few pages (p.107-121). And most other books provide algorithms just an illustration for some neat language feature. The thing is, to get a job as Scala developer these days (in competitive firms) one needs to be a competitive programmer, master of Leetcode, and Scala doesn't seem to have strong ecosystem in that regard as Java, Python or C++. Edit: in DIY spirit and as a learning exercise i'm thinking of translating Sedgewick Algorithms from Java to idiomatic functional Scala, if anyone wants to join this effort or aware of similar ones please let me know Edit 2 (in regards to comments on 'reinventing the wheel' below): if Scala is so great as a language and functional programming flagship, where are all the libraries of functionally implemented algorithms replacing conventional CLRS style imperative/mutable implementations?

Need suggestions on where and how I can practice functional programming with Scala or in general programming in Scala. New to Scala.
handsonscala is a great read for programming in general using scala. Especially if you're the practical kind of learner.

Scala at Scale at Databricks
I will toot the author's horn for him. He has a great series of Scala posts on his blog [1] and his book Hands-On Scala Programming [2] is a great introduction to building real applications with Scala so that any experienced developer can understand and extend them.
I work at a small company that has been using Scala for 7 years. Some of the prior employees clearly enjoyed playing with advanced language features and writing libraries for the most general possible case even when that made it hard to understand how they were used for the 2 actual cases we needed to address in our application code. Akka, Cats, and Shapeless were all over the place.
Those earlier employees have churned off to other places and I have successively simplified the code they wrote that is still useful, while encouraging the use of no more language power than necessary in new development. Hands-On Scala Programming is the book I give new hires as a language introduction that shows the sort of style to be preferred. It's much more like super-powered Python than like Haskell.
I have written C, JavaScript, Python, and Scala for money. When I started on Scala I had never written Java nor used any JVM language. I have come to really appreciate the rich ecosystem of JVM libraries, the instrumentation and profiling tools I get, and many aspects of the Scala language and standard library. I love Scala's collections and miss their power and ease when I'm writing Python. (Which I still do for certain scripting tasks and for accessing Python-ecosystem libraries.)

Question about Yard
An example for a very simple setup is the cmdparse gem documentation. It only has a few additional documentation files that accompany the main API documentation. The other end of the spectrum is the documentation for HexaPDF which encompasses many additional documentation files besides the API documentation and deeply integrates the API docs into the whole documentation website.

I interviewed Mike Perham (of Sidekiq) on commercializing software, and quitting his job to work on Sidekiq full time. “by March 2014 I was making more money from Sidekiq Pro sales than my Clymb salary”
HexaPDF is a Ruby OSS library with a commercial version available and profitable.

Understanding Text in PDF
TrueType subsetting mainly consists of generating the necessary glyph and various index tables, and copying over all the other necessary tables which don't need to be adjusted. See https://github.com/gettalong/hexapdf/blob/master/lib/hexapdf/font/true_type/subsetter.rb for what is needed to subset.
