From 0d5effd6afe8808296a01db102ca4c247cdcd1af Mon Sep 17 00:00:00 2001 From: eunhhu Date: Sat, 26 Sep 2026 11:33:31 +0100 Subject: Show filtered lists and their shared focus A list may now be filtered (each t in tasks where !t.done), and several filtered lists over one list share one focus: the focus view names an item, so Vega asks Pure which row shows it and highlights it only in the list that holds it; the other lists have no focus (null in the web surface's JSON, and the spoken surface names the item where it is). A click or point on a row points at the item that row shows, and the wheel on a list without the focus focuses the row under it. Pure's rows now take a mutable app. examples/today.aup shows what is open and what is done; its CLI output matches a model over random adds, moves, toggles and points into either list, and the web surface leaves the other list without a focus. --- src/vega.h | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) (limited to 'src/vega.h') diff --git a/src/vega.h b/src/vega.h index 98ed410..59a663e 100644 --- a/src/vega.h +++ b/src/vega.h @@ -45,14 +45,18 @@ unsigned vega_check(const PureModule *, void (*report)(void *, const char *name, * shortest form. false when it has no value (for example a missing item). */ bool vega_text(PureApp *, uint32_t view, size_t row, char out[VEGA_TEXT], size_t *length); bool vega_number(PureApp *, uint32_t view, size_t row, double *out); -size_t vega_rows(const PureApp *, const VegaPart *); -/* The focused row, clamped to the rows; 0 without a focus view. */ +size_t vega_rows(PureApp *, const VegaPart *); +/* The row of the focused item: the focus view names an item (an index's + * position), shown on the row that holds it; VEGA_NO_ROW when a filtered + * list leaves that item out.
