Question 1

How do I generate hasgo functions for my own struct types?

Accepted Answer

You need to use the hasgo code generator on your type definitions, but the README lacks detailed steps; check the repository for generation scripts or contributions guidelines for more information.

Question 2

Hasgo vs Pie library: which should I use?

Accepted Answer

Hasgo is inspired by Pie and offers Haskell-like signatures with immutability, while Pie might have different features. The README suggests checking Pie if a function is missing in Hasgo, so compare based on your need for functional style or specific utilities.

Question 3

Does hasgo support Go generics?

Accepted Answer

The main version does not use Go generics and relies on code generation. An experimental version, hasgo2, uses generics but requires a development Go version and is not stable for production use.

Question 4

What are the performance costs of using hasgo?

Accepted Answer

Immutable operations create new slices, leading to extra allocations that can impact performance in tight loops or memory-sensitive contexts compared to in-place modifications with plain Go.

Question 5

Can hasgo handle slices of floats or other types?

Accepted Answer

Out of the box, hasgo only supports ints and strings. For floats or custom types, you must generate functions using the code generator, which adds setup overhead.

Question 6

How to install and use hasgo in a project?

Accepted Answer

Install via 'go get -u github.com/DylanMeeus/hasgo' or add to go.mod, then import the types package. Use built-in Strings or Ints types directly, or generate for custom types as needed.
