| 1 | // select_node — drives select.js's pure half in plain Node: how a query |
| 2 | // ranks a select's options, what leaving the box after a search commits, |
| 3 | // and which blanks are prompts. Everything that touches a page stays |
| 4 | // behind select.js's `document` guard, which Node never takes. |
| 5 | // |
| 6 | // check/select_test.go is the only caller. It pipes {options, queries} |
| 7 | // on stdin and reads back each query's values, best first, and the |
| 8 | // value leaving the box would settle on; or {blanks}, and reads back |
| 9 | // what the box shows and lists for each blank option. |
| 10 | // |
| 11 | // This file lives under check/node/ beside the other Node drivers, so |
| 12 | // `go test` in check/ finds it by name; it is never embedded, and |
| 13 | // nothing in fiesta.go reaches for *.mjs. |
