But How to call these functions?

Like I wanma call FriendOf() on runtime based on function match

Wanna*

I have to select the function dynamically based on a string I recieved as an input

scastie does not respond unfortunately, so it's scalafiddle for now

you can store them as

funcs: Map[String, A => B]

and then

funcs(key)(a)

funcs: Map[String, A => B]

funcs(key)(a)

Ok so number of arguments and for types as well I should be flexible here right?

funcs: Map[String, A => B]

funcs(key)(a)

👍

It depends on what you consider flexible

Well ok

Actually I am building a dynamic compute model for apache spark

So ihave to parse a psude code dynamically on runtime in scala

That is my use case now if you have the better understanding of it you can suggest a better approach. Will be much appreciated :)

Well dynamic is dynamic, scala is for designing DSL with good static properties.
Dynamicity means you are responsible for error dispatching.
There are a lot of approaches applicable, but parsing lambdas means designing a new language.
So you probably need to read about functional language design.
Then you can formulate your langauge expressions in form of some recursive ADT or GADT and develop nice interpreter.
Scala can help you with parsing llibraries and data processing, but generally you are on your own here

Thank you for your help :) any book suggestion?

The very classic of this is https://ttic.uchicago.edu/~dreyer/course/papers/barendregt.pdf
But it isn't focused on technical details.
I'm not quite an expert in compiler books and all people I'd like to mention in this group are gone.
You can go https://t.me/CompilerDev there might me more help

редеплой походу был час назад

единственное, что после выхода след релиз кандидата мне придется маленько подрихтовать статью. там некоторый синтаксис поменялся

Просто версионируй её как сам zio: rc1, rc2, .. rc22
