[FEATURE] Initialize basic variables with shell output
Description of the requested feature
It is currently not possible to initialize basic variables using the output of a shell command. Basic variables can only be initialized using a literal value assignment:
(defvar current-volume 100)
My current workaround is to first spawn a window containing a widget which references the variable, and then updating the variable externally:
eww open my-bar && eww update current-volume=$(pamixer --get-volume)
It would be a nice addition to be able to initialize basic variables from shell output directly in eww.yuck.
Proposed configuration syntax
This could be accomplished by adding a simple boolean parameter, called for example execute, to the defvar-directive:
(defvar current-volume :execute true `pamixer --get-volume`)
If the parameter is true, the specified string gets executed in a spawned shell, and the shell's output gets assigned to the variable.
Additional context
No response
Edit: fix example code snippet.
One workaround for now is to just use a polling variable with a very very high interval, that should effectively make the command only run once
True, I didn't even think of that, because I wasn't sure if polling variables could be updated using eww update. As it turns out, they can, which is nice. Just tested it.
Could still be nice to add something like this to remove an unnecessary counter and to make the solution a bit more straight forward.
(defpoll myVariable :interval "once" ...
)
Alternatively to “once”, setting the interval to zero could also be an input to disable the timer.
