sway-wscap

Screen share a workspace instead of your entire screen, great for privacy.

Features:

  • Works with multiple monitors
  • Works with multiple applications capturing at the same time
  • Choose between full output and per workspace capture
  • Can run using dash instead of bash for a bit of extra performance

Downsides:

First downside is small, but that is "workspace wrapping" when scrolling swaybar.

Second, if switching between workspaces, the capture may sometimes not resume for up to a second or two (I know, devastating). However, the workspace switching itself is always responsive, so normal usage is not impeded.

Third, some actions may cause this script to malfunction, see below:

Don'ts:

  • Do not move the captured workspace to an other output
  • Do not click the workspace numbers in swaybar (unless you want to temporarily show that workspace)
  • Do not rapidly scroll swaybar, may sometimes cause the wrong workspace to be captured

Installation:

Clone the repo:

git clone https://github.com/iguanajuice/sway-wscap

"Install" executables:

cd sway-wscap
sudo rsync libexec /usr/local/libexec
sudo chmod +x /usr/local/libexec/sway-wscap*

Edit /etc/xdg/xdg-desktop-portal-wlr/config to look something like this:

[screencast]
max_fps=30
chooser_type=simple
chooser_cmd=/usr/local/libexec/sway-wscap-picker

Edit your Sway configururation so that workspace switching is done using sway-wscap-switcher:

Go from this:

# Switch to workspace
bindsym $mod+grave workspace 0
bindsym $mod+1 workspace 1
bindsym $mod+2 workspace 2
bindsym $mod+3 workspace 3
bindsym $mod+4 workspace 4
...

To something like this:

# Switch to workspace
set $workspace exec /usr/local/libexec/sway-wscap-switcher
bindsym $mod+grave $workspace 0
bindsym $mod+1 $workspace 1
bindsym $mod+2 $workspace 2
bindsym $mod+3 $workspace 3
bindsym $mod+4 $workspace 4
...

Mind the $ in $workspace.

The same trick should be done for your bar config. For swaybar, add these lines to its config:

bindsym button4 $workspace prev_on_output
bindsym button5 $workspace next_on_output

User's of other bars, you should be smart enough to figure this out.
