exhaustruct is a golang analyzer that finds structures with uninitialized fields

Installation

go get -u github.com/GaijinEntertainment/go-exhaustruct/v3/cmd/exhaustruct

Usage

exhaustruct [-flag] [package]

Flags:
  -i value
        Regular expression to match type names, can receive multiple flags.
        Anonymous structs can be matched by '<anonymous>' alias.

                github.com/GaijinEntertainment/go-exhaustruct/v3/analyzer\.TypeInfo
        
  -e value
        Regular expression to exclude type names, can receive multiple flags.
        Anonymous structs can be matched by '<anonymous>' alias.

Comment directives

exhaustruct supports comment directives to mark individual structures as ignored during linting or enforce it's check regardless global configuration. Comment directives have precedence over global configuration.

• //exhaustruct:ignore - ignore structure during linting
• //exhaustruct:enforce - enforce structure check during linting, even in case global configuration says it should be ignored.

Note: all directives can be placed in the end of structure declaration or on the line above it.

Also, any additional comment can be placed same line right after the directive or anywhere around it, but directive should be at the very beginning of the line. It is recommended to comment directives, especially when ignoring structures - it will help to understand the reason later.

Example

// Package a.go
package a

type Shape struct {
	Length int
	Width  int

	volume    int
	Perimeter int `exhaustruct:"optional"`
}

// valid
var a Shape = Shape{
	Length: 5,
	Width:  3,
	volume: 5,
}

// invalid, `volume` is missing
var b Shape = Shape{
	Length: 5,
	Width:  3,
}

// Package b.go
package b

import "a"

// valid
var b Shape = a.Shape{
	Length: 5,
	Width:  3,
}

// invalid, `Width` is missing
var b Shape = a.Shape{
	Length: 5,
}
