Remote - Flatpak Host

This extension enables developing on the host system while in the unofficial VSCode Flatpak.

Setup

Download the latest release .vsix here: https://github.com/ryanabx/vscode-flatpak-host-remote/releases

Open the VSCode Flatpak, and open the command palette and type Install from VSIX:

Select the released .vsix that you downloaded. Close VSCode after the extension installs.

This extension makes use of two VSCode API proposals, which means in order to use it, you must allow the extension to use the API proposals. Add ryanabx.flatpak-host-remote to the enable-proposed-api section of your ~/.vscode/argv.json (create it if it doesn't exist):

{ // Whatever came before this stays
	...,
	"enable-proposed-api": [
		"ryanabx.flatpak-host-remote"
	]
}

NOTE: This also means that I cannot upload the extension to the Microsoft Extension Registry as they do not allow extensions that use API proposals.

Start VSCode, and you should see the Flatpak Sandbox Exit options in the remote picker:

How does this work?

This extension will download the vscode-server resources to $HOME/.vscode-server-flatpak, and invoke it with flatpak-spawn --host. The server will expose itself over localhost, and the VSCode Flatpak will connect to it because the network is shared.

This requires the --share=network permission and the --talk-name=org.freedesktop.Flatpak permission, both of which are set by default in Flatpak VSCode.

The extension will also exit if it's not within a flatpak environment, so it's safe to leave enabled in general.
