# Float + resize (to 781x702) + center the Bitwarden browser-extension pop-out window.
|
|
#
|
|
# Why this exists instead of a window rule: Hyprland's `float`/`center`/`size`
|
|
# rules are "static" — evaluated exactly once, at the instant a window is
|
|
# created — and this popup opens with the generic title "Zen Browser" (same
|
|
# initialTitle/initialClass as the main browser window), only updating to
|
|
# "Extension: (Bitwarden Password Manager) - Bitwarden..." a moment after
|
|
# it's already mapped. By then the static rule has already missed its one
|
|
# chance and there's no field available at creation time to tell the popup
|
|
# apart from a normal browser window. See layout/windowrules.lua and
|
|
# https://github.com/hyprwm/Hyprland/issues/7402 for the same problem class.
|
|
#
|
|
# No socat/ncat is installed, so instead of an event-driven IPC listener this
|
|
# just polls `hyprctl clients` at a short interval with jq (already
|
|
# installed).
|
|
#
|
|
# Dispatch syntax note: Hyprland 0.55+'s Lua config changed `hyprctl dispatch`
|
|
# to take a literal Lua expression calling hl.dsp.* (e.g.
|
|
# `hyprctl dispatch 'hl.dsp.window.center()'`), not the old
|
|
# "centerwindow"-style dispatcher strings. Verified live against the real
|
|
# API in /usr/share/hypr/stubs/hl.meta.lua before wiring this in.
|
|
#
|
|
# Why it re-asserts for a few seconds instead of firing once: right after the
|
|
# popup leaves the tiled layout, Hyprland briefly re-tiles the sibling window
|
|
# to fill the freed space, and during that reflow this popup was observed
|
|
# reporting `floating: false` again for one poll tick — snapping it back to
|
|
# its old tiled geometry. Re-asserting float+center for a short settle window
|
|
# after first detection rides that out. After the settle window it's left
|
|
# alone, so a manual re-tile/move by you later isn't fought.
