go-linq VS lo

There are also libraries like https://github.com/Jeffail/tunny or https://pkg.go.dev/go.uber.org/goleak or https://github.com/fatih/semgroup to help deal with concurrency limits and goroutine lifecycle management.

As the author of https://github.com/ahmetb/go-linq, it's hard to find adoption for libraries offering "syntactic sugar" in Go, as the language culture discourages those kind of abstractions and keeping the code straightforward.

This is a lot more possible now that Go has generics (as of 1.18).

I would probably never use these, as I find such libraries are a whole new domain-specific language to learn, and often don't make things much simpler anyway, but here are some libraries where people have done something like this:

* https://github.com/ahmetb/go-linq: modelled after LINQ, but created pre-generics so only recently added some generics features

So awhile back, there was a port of Linq https://github.com/ahmetb/go-linq that ended up giving up, since then it has been continued with https://github.com/szmcdull/glinq

I am aware of this that predates generics: https://github.com/ahmetb/go-linq/blob/master/groupby.go

Might be interesting to make a library that competes with https://github.com/samber/lo?

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.
