ui-preview: hold <id or key> <pseudo> - hover, active, focus, focus-visible, checked or disabled held on from the next frame on top of the real input, by the element's key (so through model and load), let go with "" or reset; ludic.ui's held.ludic keeps them and the matcher asks it first; protocol-v1.md and smoke.txt

@ -71,6 +71,7 @@ A template error is NOT a `fail`: the request succeeded and the error is reporte
| `native <text tag> [<num w> <num h>]` | none. `<tag>` becomes an element the game draws itself: laid out with that content size in design pixels (default 0 0), drawn as a `native` line. Declare natives before the templates that use them are loaded |
| `atlas <text prefix> <text name> <int cols> <int rows> [<json list of names>]` | none. `<img src="prefix:cell">` is a cell of atlas `name`: a `cols` x `rows` grid, cells numbered row by row from 0, named by the list (a cell is also reachable by its number) |
| `image <text path> <num w> <num h>` | none. A picture's natural size in pixels, for `object-fit`; an undeclared picture has none (it fills its box) |
| `hold <text id or key> <text pseudo>` | none, or `fail "no element …"`. Holds a pseudo-class on for that element from the next frame, on top of the real input: `hover`, `active`, `focus`, `focus-visible` (which is `focus` too), `checked`, `disabled`. `""` as the pseudo lets go of that element's holds; `hold "" ""` lets go of every hold. Holds are by the element's key, so they survive `model` and `load`; `reset` clears them. `tree`, `box` and `rules` answer as if the pseudo-class were real: `rules` lists the `:hover` / `:focus` rules it makes match. Added in v1 (a host without it answers `fail "unknown request hold"`) |
| `file <text path> <text contents>` | none. Reading `path` gives these contents (an imported stylesheet, a `.po`) instead of the disk's, until replaced; every class re-reads its styles at its next show |
| `input pointer <num x> <num y> <int buttons>` | none. Held until changed. Screen pixels; buttons is a mask: 1 left, 2 right, 4 middle |
| `input wheel <num d>` | none. Added to the next frame's wheel only |
