remote

Overview ¶

Package remote demonstrates the full windowed-source loop: pkg/source coordinating a sparse pkg/table over a simulated paged HTTP API.

The "server" holds 5,000 cities and only ever answers one page at a time, after a deliberate 250ms delay so the seams are visible. Nothing about the table's 5,000 rows is real — it holds one 100-row window and draws "·" everywhere else, which is what you see for a moment when you scroll faster than the source answers.

The loop, in this file:

Init            → src.Init()            → RequestMsg
RequestMsg      → fetch (a tea.Cmd)     → fetchedMsg
fetchedMsg      → src.Deliver + SetWindow
SetWindow       → ViewportChangedMsg    → src.Viewport → RequestMsg?
QueryChangedMsg → src.SetQuery          → RequestMsg

The filter and the sort are answered by the source, not by the table: FilterRemote / SortRemote mean the table reports what the user asked for and displays whatever comes back. Type "region:europe" and the term arrives at the fake server already resolved to its column.

Keys: / filters (enter commits — the request goes out then, not per keystroke), [ ] s sort, r refetches the current window, and the usual j/k/g/G/^u/^d scroll through all 5,000 logical rows.
