A developer details building a reusable viewport component in Go for navigating large text in terminal UIs (TUIs), then using it to create 'lore', a personal terminal pager. The post covers how terminal pagers work, the $PAGER environment variable, ANSI escape codes, Unicode handling complexities (graphemes, code point widths), and the architecture of the viewport component including search/filter, item selection, and wrapping. The viewport is built on the Bubble Tea framework and is also used in the author's Kubernetes log viewer 'kl'.
