[FEATURE] Conditional Rendering of Widgets

sebastianrakel commented 1 year ago

Description of the requested feature

Hi,

i have a laptop and a workstation and they share the same bar. but my workstation does not have a battery. so there is currently following error in my configuration.

error: Failed to turn `` into a value of type json-value
   ┌─ /home/sebastian/.config/eww/eww.yuck:17:15
   │
17 │           :text {EWW_BATTERY["BAT1"].capacity + "%"} )))
   │                  ───────────

so my idea is an option/property which skips the rendering of the module. like an enable option/property.

Proposed configuration syntax

(label :enable false :text { EWW_BATTERY["BAT1"].capacity + "%" })

Additional context

No response

see #517 (comments)

Also, take a look at the eww documentation.

Okay, i tested it with the visible property, but the widget is still processed and throws errors, cause there is no battery in this device

You could try literal then, or use simplexpr features to avoid throwing errors (the recently merged json safe acess could work)

Will have a look into that, thanks!
