Wattbar
Wattbar is a minimalist battery charge monitor. It simply draws the battery level in a narrow strip along the bottom of the screen.
History
Wattbar is only the latest in a long line of battery monitors starting with YAMAGUCHI Suguru's xbattbar in 1998.
The original program has been updated by a number of different authors to support more modern hardware interfaces; the original APM was already getting replaced by ACPI in 2005, and the kernel interfaces to access ACPI information have changed significantly in the time since. Thus, in 2015, I (TQ Hirsch) rewrote the utility from scratch in Go; this version was called xbattbar3; to avoid kernel interface churn, I used UPowerd to access the battery charge status. (For the curious, I consider the ACPI version linked above to be xbattbar2, thus the next version is version 3)
In 2022, X has been starting to get a bit long in the tooth, and my laptop works far better with Wayland than X. Thus, it became time to rewrite it again; this new version needed a different name. "wbattbar" was the initial obvious choice, but leaving out the "b" made it a better pun. Aside from the fact that it renders to Wayland instead of X11, it should be a drop-in replacement for any of the previous versions of xbattbar.
