IDK

This is just a collection of functions I use to reduce the amount of go code I have to write. Makes files smaller.

Install

go get github.com/danhab99/idk@1.3

// Recommended import line
import (
  . "github.com/danhab99/idk"
)

Functions

name	usage
Check	Insert a function call that returns a value and an error
Check0	Insert a function call that returns an error
Accumulate	Collect the content of an array

Examples

package main

import (
  . "github.com/danhab99/idk"
  "os"
)

func main() {
  fileContent := Check(os.ReadFile("/tmp/example.idk"))
  Check0(os.Truncate("/tmp/example.idk", 1))

  ints := make(chan int)

  go func() {
    defer close(ints)
    for i := 0; i < 1e4; i++ {
      ints <- i
    }
  }()

  allInts := <-Accumulate(ints)
}

Ok but why tho

Look the whole thing with go error handling is that there isn't any. The only thing you can really do is panic and defer recover calls. Go encourages you to return errors to the stack to let the programmer decide what to do. But sometimes you just don't want to do anything with the error, there shouldn't be an error but if there is than panic. So why should we have to keep typing all that, or use snippits. Just wrap it in a function call and shorten the line. Trust me you stop noticing all the Checks after awhile.
