Making the plain application keys focus an existing window was the
wrong call. It reads well in a demo and it is what macOS does, but it
made "give me another terminal" the awkward case -- and on a tiling
desktop a second terminal beside the first is the normal way to work,
not an edge case. Reaching for the launcher to open a second file
manager is not an improvement on anything.
So the plain keys do what they always did, and SUPER+ALT is the new
capability rather than a tax on the old one: go to the terminal,
editor, browser, files, calculator or mail you already have, wherever
it is, and start one only if there is none.
ALT rather than SHIFT because SUPER+SHIFT is already the
window-manipulation space -- Files, Neovim and Settings would have
collided with Focus session, Taller and Shorter, and breaking two keys
out of the eight-key resize set to make room is the worse trade.
Also fixes a real trap found while using it. The Alt-Tab overlay
commits on SUPER release, which is a compositor bind running an IPC
call; if that call ever fails to land, the overlay stayed up with no
keyboard focus, no Escape handler and nothing clickable, so the only
way out was an IPC call typed into a terminal it was covering. Clicking
outside now dismisses it, clicking a row switches to that window --
which is the obvious thing to try and did nothing -- and an abandoned
switch closes itself after ten seconds. Keyboard focus still stays with
the compositor, because taking it mid-switch is what would break
stepping.
The application keys ran their command unconditionally, so pressing the
browser key twice gave you two browsers. That is the single most common
"Linux feels wrong" moment and it is a twenty-line fix: match the
window class, focus it if it is there, launch if it is not.
Two details the obvious version gets wrong. Patterns are anchored,
because an unanchored "mail" matches gmail-notifier and the mail key
would raise somebody's notifier. And class alone is not enough here:
the terminal and the editor are both kitty, so the editor bind narrows
by title or it raises whatever terminal happened to be open. The
contract's fixture contains both traps.
Found and fixed a bug this shipped with earlier today. Hyprland 0.56
dispatches through Lua, so `hyprctl dispatch focuswindow address:0x...`
is parsed as Lua source and fails with a syntax error -- which is what
the launcher's Switch Window command had been doing since it landed.
Its own contract stubbed hyprctl and recorded the arguments, so the
call looked correct and never ran. Both now use the selector form
hl.focus actually accepts, and the contract asserts the shape rather
than only that something was dispatched.
