Multi-line formatting for long parameter lists about jennifer HOT 8 CLOSED

I'll have a think... but trying to support everyone's version of exactly how they want the output to be formatted will open a rather large can of worms, so I wouldn't hold your breath!

Hmm I'm not sure I want to complicate the API with control over the formatting of the output...

from jennifer.

Agreed. I like the directness of the API as it is today.

What if the formatting were based on a simple heuristic? For example, use multi-line formatting if the parameter count is greater than 3.

How about:

package main

import (
	"os"

	"github.com/dave/jennifer/jen"
)

func main() {
	f := jen.NewFile("test")

	f.Func().Id("PrintNumbers").Call().Block(
		jen.Qual("fmt", "Println").ParamsFunc(func(g *jen.Group) {
			for idx := 0; idx < 10; idx += 1 {
				g.Line().Lit(idx)
			}
		}),
	)

	if err := f.Render(os.Stdout); err != nil {
		panic(err)
	}
}

Output:

package test

import fmt "fmt"

func PrintNumbers() {
	fmt.Println(
		0,
		1,
		2,
		3,
		4,
		5,
		6,
		7,
		8,
		9)
}

That's a bit of a kludge 😉

Not perfect (final parameter on same line as )), but it'll work for me for now! Thanks for the quick support, @dave! 🎉

Also, if you change your mind about it, I'd be happy to take a try at contributing the change.

But thanks for the input - it's really useful to see how people are using it!
