Dashlights

turn ENV vars into dashboard diagnostic lights for your shell

Dashlights is a simple binary that you drop somewhere in your PATH. It lets you turn this:

~
❯ export DASHLIGHT_HEXAGRAM_4DCB_FGRED="get up and stretch a bit" DASHLIGHT_LINK_1F517="VPN is up"

into this:

~
䷋  🔗
❯

Why?

From time to time, you may want to bring attention to the fact that you're operating in a certain state or mode, and highlight this in your shell. Dashlights provides a simple interface between shell functions or aliases and a dash display, via exported ENV vars.

Any time you export a var of the following form in your shell, dashlights can parse it and render a UTF-8 glyph, with optional foreground and background coloring applied:

 prefix            utf8 hexcode
DASHLIGHTS_BULBNAME_HEXSTRING_OPTIONALCOLORS...
             label              one or more color codes
