// What the visitor lands in: one tab, three tiled panes, the config open in
// vim beside them, and a welcome float on top of it all.
//
// slosh --layout /root/demo.layout
//
// which is the line /etc/inittab respawns. No `cwd=` anywhere in it: a relative
// path in a layout file means the directory the file is in, and a pane with no
// cwd at all starts there too -- so every pane here starts in /root.
layout {
tab name="demo" purpose="demo" {
// The greeting, and a shell under it. This pane was *given* a command,
// so typing `exit` leaves the corpse and an offer to re-run it (`C-a r`)
// rather than closing the pane -- which is a pane state worth seeing.
pane purpose="demo:welcome" command="cat /etc/motd; exec /bin/sh"
// The config, already open and highlighted: the discovery C-a e would
// make, made before anyone has to make it. Quitting vim leaves the
// corpse and its [re-run], so closing it is as reversible as
// everything else here.
pane purpose="demo:config" command="vim /root/.config/slosh/config.kdl"
pane split="rows" {
// Laid out, running nothing, started by your first keystroke: the
// pane shows what it *would* run. Here it is also the proof that
// the machine underneath is a real riscv64 one.
pane purpose="demo:machine" command="cat /proc/cpuinfo" suspended=true
// No command: the session's shell, in /root.
pane purpose="demo:shell"
}
// The welcome, floating over everything with the focus, so the first
// thing anyone does is read it and the second is close it -- C-a x, or
// the ✕ it wears, both of which it teaches. `cat` holds it open (a
// command that exited would leave a corpse; this one only ends when
// the pane closes), and the float's shadow plus everyone else's
// dim_unfocused make it read as the dialog it is.
// Size is the text's (56 columns and 21 rows of it, plus the frame);
// position is
// deliberately absent, so the float takes the centred default at
// whatever size the browser gave the terminal. A smaller screen
// clamps the rect and nothing is owed.
