Action bar

A staff member on duty has half a dozen toggles running at once, and reading each one means opening something. The action bar puts the answer on screen: which switches are on, and how the server is holding up, on a single line that redraws itself.

Module id actionbar, switch modules.actionbar, files under modules/actionbar/.

There is no command: the line appears while it applies and is gone when it does not.

The two lines

Staff mode wins, because somebody on duty and vanished is reading the staff line, which already says the vanish. Leaving a line empty turns that situation off.

The vanish line exists for the state nothing else reports: /vanish on its own leaves no staff hotbar to read and no staff sidebar, so without it nothing on screen says you are hidden.

Both are ordinary text with placeholders in them, so a server that wants a different summary edits the file rather than the plugin.

Ticks and crosses

%staff_actionbar_check_<placeholder>% writes icon-on or icon-off for any other placeholder that reads as true or false. The placeholder named after check is written without its percent signs, so %staff_actionbar_check_staff_vanished% asks %staff_vanished%.

true, yes, on, 1 and enabled are the answers that get the tick. Everything else gets the cross, an unresolved placeholder included: a module that is switched off is off, and saying so is more honest than an error across the screen.

The shipped line

staff-mode: '{primary}STAFF {letters_black}▎ %staff_actionbar_check_staff_vanished% {letters}Vanish {letters_black}· %staff_actionbar_check_staff_mining_alerts_active% {letters}Alerts {letters_black}· %staff_actionbar_check_staff_staffchat_active% {letters}Chat {letters_black}▎ {letters}TPS {info}%server_tps% {letters_black}· {letters}MSPT {info}%server_mspt% {letters_black}· {letters}CPU {info}%server_cpu_process:percent%'
vanish: '{warning}VANISH {letters_black}▎ {letters}Hidden and {highlight}off duty {letters_black}▎ {letters}TPS {info}%server_tps% {letters_black}· {letters}MSPT {info}%server_mspt%'

Vanish, mining alerts and staff chat as ticks or crosses; TPS, MSPT and CPU as numbers. Any placeholder your server resolves works here, so the summary is whatever your staff need to see.
