FuncFrog VS lo

func GetIDs(...) ([]string, ...) { <...> users := GetUsers(...) return ff.Map(users, domain.UserGetID).Do(), ... } ``` Now it's that easy! Furthermore you may like to write gogenerate function to generate such methods for each domain struct. Also there are more cool features, minimal-lock parallelism, error handling etc. in the libtaty https://github.com/koss-null/FuncFrog Cheers!

if it have to be in FP style, this one is better

still prefer non-FP part tho

Hi there! I have finally released a stable version of my stream-like library. It supports some basic features such as Map, Reduce, Filter, Sort, Any, First on any slice or generating function, easy out-of-the-box parallelism with minimum locks and overhead on a regular for cycle. Here it is: https://github.com/koss-null/FuncFrog First of all I will appreciate any code review. Any feedback are welcome. At second, I want to ask the community, what features do you expect to be in such kind of a library and how do you expect them to be implemented? It looks like I need to add some Collect function to be able to produce not only slices, and also add some sources such as BufferedReader or channel.

Hi gophers! In last months I've been working on a FuncFrog - java stream-api - like library, which is fast, parallel, lazy-evaluated and generic-based! You can check it out here: https://github.com/koss-null/FuncFrog

Check this out. I will be glad to any comments and notes https://github.com/koss-null/lambda/tree/0.3.0

I am rly strugging with it developing this:https://github.com/koss-null/lambda

Hi! Some te ago I've released the first beta of my stream-api like library. It have become much more useful and stable since then. Here is is: https://github.com/koss-null/lambda

Check the code out here: https://github.com/koss-null/lambda

On the other hand, I advise you NOT to use this kind of library and write simple, fast go code most of the time, with the occasional generics helper. Why the hell would I clutter my code with, for example: https://github.com/samber/lo?tab=readme-ov-file#fromentries-...

This wasn't feasable without generics, and now with generics they're already adding some convenience functions to the stdlib, like in the slices package.

For map, reduce etc it's not in the stdlib yet, but you can use https://pkg.go.dev/github.com/samber/lo

In particular, I'd like recommend samber/lo, this is a lodash generic tool for golang.

What are some 3rd-party libraries for Go that you use often/all the time? Instead of "just implement everything yourself", I would really like to get some tips. For instance, a few days ago I discovered https://github.com/samber/lo , which looks very good if I want to have list comprehensions (Python) / LINQ methods (C#). https://pkg.go.dev/github.com/atotto/clipboard is also good for clipboard operations. What else do you suggest and for what task?

A simple alternative is the combination of:

- https://github.com/samber/lo

- https://github.com/samber/mo

The split is also nice as you can choose to just use the generic convenience functions from lo without the more FP related things from mo.

Some packages offer utilities to gather results from goroutines, such as multierror.Group or parallel.Map in samber/lo.

I came across samber/log a package based on generics for providing utility methods.
