Show a bool as true or false, and make the examples' flags bools

2026-09-30T14:29:20Z

aup and Pure now have a bool (Pure 016): a view or column may be one. vega_text writes it as true or false, as a string's interpolation does, so every surface shows the same words: the CLI, the TUI's cells, speech and the web surface's JSON (a value's text) and page. An app that wants other words picks them with a conditional (if t.done { "done" } else { "" }). The flags of the examples are bools: todo's done and urgent, today's done, the stopwatch's running. vega.when takes the bool as it took the number. bools checks a bool field and a bool column on the CLI, the TUI, speech and the web surface: true and false, never 1 and 0.

Count the open tasks in the todo example

The left field said how many tasks there were; it now says how many are still open, "2 of 3", with aup's count(t in tasks where !t.done), which Pure runs as a fold over the list on every surface. The reference model counts the same, and in the browser the field follows a task marked done.

Add the first component and three surfaces

Vega reads a verified Pure module by convention: a table view with a label column is a list (with optional badge, detail and tone), any other table is a table, _focus is its focused row, a title view is the title and other views are fields. lib/vega.aup gives aup apps the tones, which say what a row means; each surface decides how it looks or sounds. vega tui draws the screen in a terminal, keeps the focused row in view and evaluates only the cells on screen; vega cli prints plain lines for pipes; vega say speaks the screen and each focus change as sentences. Display width handles Hangul, CJK, emoji, combining marks and controls. tests/check.py compares the CLI and NUI output with a reference model of examples/todo.aup line for line, checks 9,600 TUI frames for scrolling, focus, badge alignment and the number of cells evaluated, drives the interactive TUI on a pseudo-terminal, and runs every aup example on every surface.
