Add GO Templates to the SDK Generator

[eldadfux]

We need help adding GO templates to this project to allow easy generation of GO SDKs for Appwrite server.

A full guide on how to add new language support to the Appwrite SDK generator is located here:

@panz3r, I finally had some time to play around with the Go implementation. I have generate a demo SDK using the Appwrite API spec in this demo repo: https://github.com/aw-tests/sdk-for-go

When I run this example code:

package main

import (
    "fmt"
    "os"
    "github.com/aw-tests/sdk-for-go"
)

func main() {
    var client := appwrite.Client{}

    client.SetProject("")
    client.SetKey("")

    var service := appwrite.Avatars{
        client: &client
    }

    var response, error := service.GetBrowser("aa")

    if error != nil {
        panic(error)
    }

    fmt.Println(response)
}

I get the following errors:

go: finding github.com/aw-tests/sdk-for-go latest
go: downloading github.com/aw-tests/sdk-for-go v0.0.0-20200128164133-02ad4443fc25

./main.go:15:17: syntax error: unexpected :=, expecting =
./main.go:16:24: syntax error: unexpected newline, expecting comma or }
./main.go:19:25: syntax error: unexpected :=, expecting =

Any idea how can we fix this?

Hi @eldadfux ,

package main

import (
    "fmt"
    "os"
    "github.com/aw-tests/sdk-for-go"
)

func main() {
    var client := appwrite.Client{}

This line should be

    client := appwrite.Client{}

    client.SetProject("")
    client.SetKey("")

    var service := appwrite.Avatars{

This one should be:

 service := appwrite.Avatars{

but there's an issue with the generated SDK, since client is a private field of the Avatars struct it cannot be set this way, to fix this there are 2 ways:

• Add a method New{{ServiceName}}Service(clt *Client) to the generated SDK
• make the client field public

I'd advice for the first one.
The method would look like this

func NewAvatars(clt *Client) *Avatars {
	return &Avatars{
		client: clt,
	}
}

        client: &client
    }

    var response, error := service.GetBrowser("aa")

This one also should be

response, error := service.GetBrowser("aa", 100, 100, 80)

N.B: All 4 params are required.

    if error != nil {
        panic(error)
    }

    fmt.Println(response)
}
