Command

hollow dash

Attaches to a running server over the control socket and redraws on a timer. There is no keyboard interaction and no raw mode on any platform, which is what lets the dashboard run without touching terminal state beyond the alternate screen and the cursor.

Usage

hollow dash [flags]

Flags

--ascii
draw with ASCII instead of box-drawing characters
--height <int>
frame height; default is $LINES, then 30
--interval <duration>
default 500ms
how often to redraw, and how often to ask for a snapshot
--plain
append a frame per interval instead of redrawing in place, and write no escape sequences
--target <string>
default "127.0.0.1:15354"
control socket of the server to watch
--width <int>
frame width; default is $COLUMNS, then 100

Real output
