GoBuilderGenerator

IntelliJ IDEA / GoLand plugin for generating Builder pattern code of Go struct from selected struct code.

How to install

• in IntelliJ IDEA / GoLand : go to Settings/Preferences → Plugins → Browse repositories and search for Go Builder Generator

or

• download it and install via Settings/Preferences → Plugins → Install plugin from disk

How to use it

1. Select the struct code

2. Shortcut: (Alt + B) or Menu: [Code] → [Generate Go Builder Pattern Code]

Demo

If we have a struct like this:

type CreateDisk struct {
    RegionID     string //required for creating CreateDisk struct
    ZoneID       string //required for creating CreateDisk struct
    DiskName     string
    Description  string
    Encrypted    bool
    DiskCategory string
    Size         int
    SnapshotID   string
    ClientToken  string
}

After generated, we got

• type CreateDiskBuilder struct for storing *CreateDisk
• func NewCreateDiskBuilder() for creating a builder
• functions for receiving parameters
• func Build() for checking and building

// CreateDisk builder pattern code
type CreateDiskBuilder struct {
    createDisk *CreateDisk
}

func NewCreateDiskBuilder() *CreateDiskBuilder {
    createDisk := &CreateDisk{}
    b := &CreateDiskBuilder{createDisk: createDisk}
    return b
}

func (b *CreateDiskBuilder) RegionID(regionID string) *CreateDiskBuilder {
    b.createDisk.RegionID = regionID
    return b
}

func (b *CreateDiskBuilder) ZoneID(zoneID string) *CreateDiskBuilder {
    b.createDisk.ZoneID = zoneID
    return b
}

.
.
.

func (b *CreateDiskBuilder) ClientToken(clientToken string) *CreateDiskBuilder {
    b.createDisk.ClientToken = clientToken
    return b
}

func (b *CreateDiskBuilder) Build() (*CreateDisk, error) {
    // May miss required parameters
    return b.createDisk, nil
}

When we use it

createDisk, err := NewCreateDiskBuilder().
    DiskName("test name").
    Description("desc").
    Size(20).
    SnapshotID("").
    Build()
if err != nil {
    // May miss required parameters
    return
}
// Do something with createDisk
