Broadway enables you to use your GTK apps right in the web desktop.

Broadway doesn't virtualize apps, it's a GTK backend (thus, it's faster). Instead of rendering apps on the screen (with the X server/Wayland/other), it's streaming it via WebSockets (compressed, and only updated regions are refreshed).

Resources:

• Official documentation:https://developer.gnome.org/gtk3/stable/broadwayd.html
• World of Gnome article:http://worldofgnome.org/running-gtk-apps-on-web-with-node-broadway/
• LinuxFr article (in French):http://linuxfr.org/users/ondex2/journaux/gtkhtml5-libreoffice-dans-le-cloud

This is an experimental technology! Use it carefully!

You'll have to install Broadway on your server:

• In Ubuntu:https://launchpad.net/~malizor/+archive/gtk-broadway
• In Archlinux:https://aur.archlinux.org/packages/gtk3-broadway/

You'll have to install thebranchfeat-broadway of Symbiose in order to get latest Broadway updates in the webos.

First, start the Broadway server:

broadwayd -a 0.0.0.0 -p 8080 :2

Options:

• -a: the bind address
• -p: the server port
• :2: the display name

Open a terminalon your server, and execute the following commands:

export GDK_BACKEND=broadwayexport BROADWAY_DISPLAY=:2

And execute the app you want to use, for examplegnome-calculator orsoffice --writer (LibreOffice).

To use LibreOffice, you must executeexport SAL_USE_VCLPLUGIN=gtk3 before runningsoffice --writer, in order to use GTK3.Seehttps://wiki.documentfoundation.org/Using_LibreOffice_in_a_Web_Browser

Then, you should be able to accesshttp://localhost:8080 (replace the domain by yours).

You should be able to run multiple instances ofbroadwayd, just be sure to use a different port and display for each of them.

Once configured, enable Broadway support in the webos. For the moment, you'll have to execute this commandin a Symbiose terminal:broadway.

Options:

• -H or--host: specify the host to connect to (e.g.broadway --host http://example.com:8081). Defaults tohttp://localhost:8080.

To start the Broadway server, executebroadwaydfrom a Symbiose terminal. You will then be able to start an app by typing its name.

Config is stored in/etc/broadway.

You can find logs in:

• /var/log/broadway-server.log for the server
• /var/log/broadway-apps.log for GTK3 apps

You can change the GTK theme by editing~/.config/gtk-3.0/settings.ini (seehttp://worldofgnome.org/running-gtk-apps-on-web-with-node-broadway/ sectionTheming):

[Settings]gtk-application-prefer-dark-theme=0gtk-theme-name=Adwaita

Assumed you have Adwaita theme installed (you can choose another e.g. Elementary if you want).
