Window rule ignored for firefox openned window

[vp1981]

Hello.

I have this window rule in my hyprland.lua to set specific window settings for the "NoScript" window launched from the context menu (right-click -> NoScript):

hl.window_rule({
  name = "noscript-ff",
  match = {
    title = "Extension: (NoScript)(.*)"
  },

  fullscreen = false,
  fullscreen_state = "0 0",

  float = true,

  -- size = { "(monitor_w*0.25)", "(monitor_h*0.25)"}
  size = { 800, 600 }
})

But it seems this rule isn't applied after hyprctl reload, and the window always opens maximized:

$ hyprctl clients -j
...
},{
    "address": "0x5582969ba980",
    "mapped": true,
    "hidden": false,
    "visible": true,
    "acceptsInput": true,
    "at": [-1900, 44],
    "size": [1880, 1016],
    "workspace": {
        "id": 2,
        "name": "2"
    },
    "floating": false,
    "monitor": 1,
    "class": "default",
    "title": "Extension: (NoScript) - NoScript — Firefox Nightly",
    "initialClass": "default",
    "initialTitle": "Firefox Nightly",
    "pid": 651266,
    "xwayland": false,
    "pinned": false,
    "fullscreen": 1,
    "fullscreenClient": 1,
    "overFullscreen": false,
    "grouped": [],
    "tags": [],
    "swallowing": "0x0",
    "focusHistoryID": 1,
    "inhibitingIdle": false,
    "xdgTag": "",
    "xdgDescription": "",
    "contentType": "none",
    "stableId": "18000054"
},{
...

Why doesn't Hyprland apply that rule? Did I miss something?

The regex.

EDIT: Also size was not the correct format.

hl.window_rule({
  name = "noscript-ff",
  match = { title = "Extension: (NoScript).*" },
  fullscreen = false,
  fullscreen_state = "0 0",
  float = true,
  size = "800 600"
})

size is fine the way it was,both work

[tekstryder]

Ah, looking forward this this stuff getting standardized eventually.

[wabarTM]

if you look closely you will see that initial_class and initial_title are different AND the rules you want to apply are STATIC, which means they apply only when window is spawned and match'ed against initial's

this is a browsers problem in general, nothing you can do. maybe yell at some devs

[tekstryder]

Yeah, attention to details.

Installed the extension to replicate... and this is busted as you described. Nothing to match on.

class: firefox
title: Extension: (NoScript) - NoScript — Mozilla Firefox
initialClass: firefox
initialTitle: Mozilla Firefox

[wabarTM]

one thing you can do is:
on title change check if title has extension name and class is firefox - float it

[vp1981]

Thanks, guys, that was helpful.

So it is a common problem, but I think @wabarTM's idea sounds good to me.

[tekstryder]

So, were you able to implement a solution?

[vp1981]

@tekstryder, I went with the idea of cascading window rules. The "common" one makes the firefox window floating and explicitly sized. Then the "main" rule adjusts the size:

hl.window_rule({
  name  = "firefox-common",
  match = {
    initial_class = "default",
    initial_title = "Firefox(.*)"
  },

  float = true,

  tag = "+browser",

  fullscreen = false,
  fullscreen_state = "0 0",

  size = { 800, 600 }
})
hl.window_rule({
  name = "firefox-default",
  match = {
    class = "default",
    initial_title = "Firefox"
  },

  workspace = 2,

  tag = "+main",

  size = { "(monitor_w*0.65)", "(monitor_h*0.85)" },
  move = { "(monitor_w*0.35)", 15 }
})

Well I use neither Firefox nor noscript, but wanted to see if this was possible.

Was a frikken chore but finally got it.

hl.on("window.open", function(w)
    if w.class ~= "firefox" then return end
    if w.initial_title ~= "Mozilla Firefox" then return end

    local ff_windows = hl.get_windows({ class = "firefox" })
    if #ff_windows <= 1 then return end

    hl.dispatch(hl.dsp.window.float({ action = "set", window = w }))

    local sub
    sub = hl.on("window.title", function(tw)
        if tw.address ~= w.address then return end
        if tw.title == ""
            or tw.title == "Mozilla Firefox"
            or tw.title == "about:blank"
            or tw.title:match("^about:.*Mozilla Firefox$") then return end

        sub:remove()

        if tw.title:match("^Extension: %(NoScript%)") then
            hl.dispatch(hl.dsp.window.resize({ x = 800, y = 600, window = tw }))
            hl.dispatch(hl.dsp.window.center({ window = tw }))
            hl.dispatch(hl.dsp.focus({ window = tw }))
        else
            hl.dispatch(hl.dsp.window.float({ action = "unset", window = tw }))
        end
    end)
end)

For whatever reason that stupid window disappears when the cursor is moved outside of it's bounds.

Once I finally got the damn thing to float the cursor was elsewhere, requiring it to be focused as well.

[vp1981]

It's heavy, but interesting. I'll use it for learning.

Yeah, I noticed that as well, but I find it useful. Besides, it might be the default behavior of the NoScript context menu window.
