Host ​

The rb.host table provides information about the current machine and user. It is populated once at startup from POSIX syscalls — no environment variables are used.

lua
local rb = require("rootbeer")

if rb.host.os == "macos" then
    -- macOS specific config
end

if rb.host.hostname == "work-macbook" then
    -- work machine overrides
end
