Merge concurrent outputs for a status bar.

Programs like lemonbar and i3bar have become popular in recent years, and with good reason. These programs read from standard input and then output what they receive on a status bar. For the most part, their output is identical to their input, but they accept some format strings which allow the user to specify things like colors, justification, and clickable areas.

A typical status bar script looks something like this: a shell script, is used to collect and format the output of various commands. The main problem with this method is that it's rather difficult to handle timing correctly. A counter showing the number of outdated programs on the system can be updated less frequently than a clock.

Admiral runs programs specified by the user and prints their output. It allows for a clear separation of different sections, which simplifies configuration. Each program is run in its own thread. This means that each section is updated independently of the other sections. It also means that if something fails, it fails independently of the other sections.
