godash

hatena/godash is a minimal wrapper of https://github.com/samber/lo.

Motivation

https://github.com/samber/lo is a nice library, but in some cases teams do not want to have all of the helper functions available. Some helper functions defined in samber/lo are actually already available as part of the official slices package.

hatena/godash is meant to only provide a small portion of samber/lo's functions:

• functions that are not available via Go's standard library
• functions that are not "too much", such as "Conditional helpers" or "Error handling"

Usage

Install the package to your repo with go get.

go get -u github.com/hatena/godash

Sample usage:

package main

import (
	"fmt"

	"github.com/hatena/godash"
)

func main() {
	integers := []int{0, 1, 1, 3, 2, 1, 1, 0}
	fmt.Println(godash.Chunk(integers, 3))
}

Recommended golangci-lint configuration

Since this package aims to only present a subset of functions from samber/lo, it is recommended to add linter settings to deny importing directly from samber/lo. (If you want to use samber/lo directly, then there is no meaning to use hatena/godash).

Below is a minimal .golangci.yml configuration to deny samber/lo imports.

linters:
  enable:
    - depguard

linters-settings:
  depguard:
    rules:
      deny-samber-lo:
        deny:
          - pkg: "github.com/samber/lo"
            desc: Use github.com/hatena/godash instead.

Once you have .golangci.yml, make sure to run golangci-lint via CI. Below is an example for GitHub Actions.

  push:
    branches: main
