Portal

Portal is a Go module providing developer friendly functions for accessing the XDG Desktop Protocol D-Bus API. The goal of this project is to be toolkit agnostic and allow using the portals without needing to access libportal through CGo.

Using the portals allow applications to request information from the user even when running inside a sandbox like Flatpak. As such, it is possible to open file dialogs, open links in the browser, send notifications and much more in a way that integrates well with the desktop environment. This also avoids needing to open up permissions in the sandbox.

API

The api of this Go module is designed to closely follow the structure naming of the upstream APIs. This means, in practice, that each D-Bus interface is implemented as its own package here. However, care is taken to be developer friendly and integrate seamlessly with native Go types.

• Documentation for this module and all of its packages can be found on pkg.go.dev: https://pkg.go.dev/github.com/rymdport/portal
• Documentation for the D-Bus protocol of the portals: https://flatpak.github.io/xdg-desktop-portal/docs/api-reference.html

The version of this module's API is still in a v0.X.Y state and is subject to change in the future. A release with breaking changes will increment X while Y will be incremented when there are minor bug or feature improvements.

Example

The following example showcases how a file chooser can be opened for selecting one or more files.

package main

import (
	"fmt"
	"log"

	"github.com/rymdport/portal/filechooser"
)

func main() {
	options := filechooser.OpenFileOptions{Multiple: true}
	files, err := filechooser.OpenFile("", "Select files", &options)
	if err != nil {
		log.Fatalln(err)
	}

	fmt.Println(files)
}

• This project is used as of the v2.5.0 release of Fyne.
  • All the old theme watching code has been replaced by the settings package (and appearance subpackage) from this module. The filechooser and notification packages replace the old Fyne-code when compiling with -tags flatpak.
