gominfmt makes the Go code more compact to aid further compression; revert with gofmt

go/minformat

This package formats the Go source code in a way so it becomes more compact. It can be considered to be a minifier, although it doesn't make irreversible transformations by default (well, it does remove all comments).

The result can become readable again after running go/format, making this pipeline possible:

1. Minify the code before transferring it over a network
2. Send the (potentially further compressed) minified source code
3. On the receiving side, run gofmt to get the canonical formatting

For (3) I would recommend using gofumpt.

Example

Suppose that we have this hello.go file:

package main

import (
	"fmt"
)

func main() {
	fmt.Println("Hello, playground")
}

It will be formatted into this:

package main;import("fmt");func main(){fmt.Println("Hello, playground")}

Depending on the file, it usually cuts 10-50% of the file size.
