- Introduce typed msgs: connectedMsg, disconnectedMsg, errorMsg, and netMsg
- connectCmd now returns connectedMsg on success instead of “[connected]”
- Add readLineCmd to read a single line via bufio.Reader and emit netMsg
- Handles io.EOF as disconnectedMsg; reports other errors as “[error] read: …”
- Update loop:
- On connectedMsg: store conn, append “[connected]”, schedule first readLineCmd
- On netMsg: append message, schedule next readLineCmd unless it’s a read error
- On disconnectedMsg: append “[disconnected]”, close and clear conn
- UI tweaks: textarea placeholder uses "..." and height reduced from 3 to 2
- Window sizing: set viewport width; removed old netMsg branch now superseded by typed msgs
This removes the scanner goroutine pattern in favor of Cmd-driven incremental reads.
- Add net/bufio/time imports and model fields (conn, server, err)
- initialModel now accepts server address; display it as header
- Init batches textarea.Blink with connectCmd to dial TCP on startup
- Implement connectCmd with 3s timeout; emit [connected]/[disconnected]/error via netMsg
- Spawn scanner goroutine to read lines from conn and forward as netMsg
- Implement sendCmd to write input lines to the connection
- Update: on Enter, send via sendCmd instead of local echo; handle netMsg to append messages and status
- Close connection on Ctrl+C/Esc
- main: start local TCP server in goroutine; delay 200ms; connect to 127.0.0.1:9000
- Minor: append textarea cmd only if non-nil; render server header above viewport
