broadwayd

[--address ADDRESS]
[--unixsocket ADDRESS]
[:DISPLAY]

broadwayd is a display server for the Broadway GDK backend. It allows multiple GTK+ applications to display their windows in the same web browser, by connecting to broadwayd.

When using broadwayd, specify the display number to use, prefixed with a colon, similar to X. The default display number is 0.

broadwayd :5

Then point your web browser at http://127.0.0.1:8085. Start your applications like this:

GDK_BACKEND=broadway BROADWAY_DISPLAY=:5 gtk3-demo

You can add password protection for your session by creating a file in $XDG_CONFIG_HOME/broadway.passwd or $HOME/.config/broadway.passwd with a crypt(3) style password hash. A simple way to generate it is with openssl:

openssl passwd -1  > ~/.config/broadway.passwd


.PP --port


Use PORT as the HTTP port, instead of the default 8080 + (DISPLAY - 1).


.RE
.PP --address


Use ADDRESS as the HTTP address, instead of the default http://127.0.0.1:PORT.


.RE
.PP --unixsocket


Use ADDRESS as the unix domain socket address. This option overrides --address and --port. It is available only on Unix-like systems.
