newconstruct

newconstruct is a simple command-line tool for Go that automatically generates a New... constructor function for a given type definition in a source file. It is designed to be integrated with editors like Neovim to speed up development.

Features

• Generates constructors for both struct types and simple type definitions (e.g., type Name string).
• For structs, the constructor accepts parameters for all fields.
• Parameter names are automatically generated as lowercase versions of field names.
• Fast and simple, designed to be called by an editor plugin.

Installation

To install the newconstruct executable, ensure you have Go installed and your GOPATH is set up correctly, then run:

go install [github.com/ddromanidis/newconstruct@latest](https://github.com/ddromanidis/newconstruct@latest)```

## Example

```go
package models

import "time"

// Relative path is models/user.go
// Line of User struct is number 7
type User struct {
    ID        int
    FirstName string
    IsActive  bool
    CreatedAt time.Time
}

newconstruct --file=models/user.go --line=7```

This will generate an output to stdout:

```go
func NewUser(id int, firstname string, isactive bool, createdat time.Time) User {
	return User{
		ID:        id,
		FirstName: firstname,
		IsActive:  isactive,
		CreatedAt: createdat,
	}
}
