fillstruct

fillstruct - fills a struct literal with default values

For example, given the following types,

type User struct {
	ID   int64
	Name string
	Addr *Address
}

type Address struct {
	City   string
	ZIP    int
	LatLng [2]float64
}

the following struct literal

var frank = User{}

becomes:

var frank = User{
	ID:   0,
	Name: "",
	Addr: &Address{
		City: "",
		ZIP:  0,
		LatLng: [2]float64{
			0.0,
			0.0,
		},
	},
}

after applying fillstruct.

Installation

% go get -u github.com/davidrjenni/reftools/cmd/fillstruct

Usage

% fillstruct [-modified] -file=<filename> -offset=<byte offset> -line=<line number>

Flags:

-file:     filename
-modified: read an archive of modified files from stdin
-offset:   byte offset of the struct literal, optional if -line is present
-line:     line number of the struct literal, optional if -offset is present

If -offset as well as -line are present, then the tool first uses the more specific offset information. If there was no struct literal found at the given offset, then the line information is used.
