Get WM info into eww

[VuiMuich]

Hi,
first of all thanks, eww is absolutely awesome!

I just have one thing I couldn't figure out yet:
how do I get info from the WM like window-title of the focused window, status of the workspaces etc.?

I am using leftwm and for some bars pipes it's state to the launcher of the bar. For example with xmobar it looks something like this:

leftwm-state -w $index -t $SCRIPTPATH/template.liquid | xmobar -p "$size" $SCRIPTPATH/xmobar-conf │ ig.hs &

Or with polybar it launches the command from within polybar.config so I tried:

<script-var name="leftwm-state" interval="55ms">leftwm-state -w 0 -t ~/.config/leftwm/themes/current/template.liquid</script-var>

But the variable empty.

Exemplary the ouput of leftwm-stat looks like this:

> leftwm-state -w 0 -t ~/.config/leftwm/themes/current/template.liquid
%{F#554d8b}%{B#232131}  Home  %{B-}%{F-}%{F#554d8b}%{B#232131}  Web  %{B-}%{F-}%{F#d8d8d8}%{B#554d8b}  Code  %{B-}%{F-}%{F#554d8b}%{B#232131}  Misc  %{B-}%{F-}%{F#554d8b}%{B#232131}  5  %{B-}%{F-}%{F#999999}%{B#232131} · %{B-}%{F-}%{F#999999}%{B#232131} · %{B-}%{F-}%{F#999999}%{B#232131} · %{B-}%{F-}%{F#999999}%{B#232131} · %{B-}%{F-}%{r}%{F#554d8b}%{B#232131}  leftwm-state -w 0 -t ~/.config/leftwm/themes/current/template.liquid /home/vuimuich/.config/leftwm/themes/floaters  { %{B-}%{F-}

Bonus will be to parse this, so the workspaces will get assigned to buttons, but at first I would be happy to get leftwm-state at least read..

I'm assuming that that command continuously prints output, whenever the state changes, right? In that case, you don't want to set an interval, as that reruns the command every 55ms. The likelyhood of anything happening within those 55ms is rather low, thus probably you're just never getting any output for long enough to register.

Try just removing interval="55ms" from your script-var and see if that helps

Ok, slowly I feel I am doing any possible stupid mistake.
With the literal being as above, now I get
Faailed to parse eww xml literal: ParserError(UnknownToken(TextPos { row: 1, col: 74 }))
Which is exactly the opening '<' of the second button.
Do I need to escape some characters for the parser to get this right?

[elkowar]

Well, no, that just means your script is outputting invalid xml ig

But when I take the output of eww state and copy the variable wmstate and paste it in place of <literal content={{wmstate}}/> the buttons are drawn (of course it's static except hover and onclick then).

For reference again: this is what the <script-var name="wmstate"> contains:

<button class="ws-button-busy" onclick="wmctrl -s Home">  Home  </button><button class="ws-button-busy" onclick="wmctrl -s Web">  Web  </button><button class="ws-button-mine" onclick="wmctrl -s Code">  Code  </button><button class="ws-button-busy" onclick="wmctrl -s Misc">  Misc  </button><button class="ws-button-busy" onclick="wmctrl -s 5">  5  </button><button class="ws-button" onclick="wmctrl -s 6"> · </button><button class="ws-button" onclick="wmctrl -s 7"> · </button><button class="ws-button" onclick="wmctrl -s 8"> · </button><button class="ws-button" onclick="wmctrl -s 9"> · </button>

I will try to put this in a static variable, and also run eww with RUST_TRACEBAK again.

a literal needs to take a single element, so you'll need to wrap your buttons in a <box> or something like that.

[VuiMuich]

That did the trick! Thanks!
I will compile the infor for the proper solution into one comment later.

(Just one minor thing that puzzles me is how to space buttons properly, but I guess this is just getting more fluent in css and tag parameters:
)

This compiles the key insights of the thread in the other suggestion in order to have a solution in a glance:

• In order get dynamically generated cal code from a script use the <literal> tag
• The literal tag receives the xml code with it content parameter like this <literal content={{variable-Name}}/>
• the literal only takes one element, if more elements are needed put them in a <box>
