Feature Request: LitHex, LitBit, LitOct

[bangzek]

I work on low level binary protocol stuff and need to generate file using jen. I wish there's LitHex and LitBit so my generated code could use 0xFF and 0b1111_0000 literal.

Can you give me examples of this syntax used in code?

[bangzek]

Take this code:

	f := NewFile("util")
	f.Func().Id("positive").Params(Id("b").Byte()).Bool().Block(
		Return(Id("b").Op("&").Lit(0x80).Op("==").Lit(0x00)),
	)
	fmt.Printf("%#v", f)

which will generate:

package util

func positive(b byte) bool {
	return b&128 == 0
}

I want to change the output b&128 to b&0x80 so it would be clear to human why it using that magic number.

I hope it clear to you.

Aaah ok I see... I think unfortunately this will have to be a no... Jennifer is concerned with outputting code that compiles correctly, not code that is pretty or easy to read... The API is already rather cluttered already, and adding more methods to tweak the formatting or readability of the output code is an deep rabbit hole!
