Client/main:
- Colorize display: hide raw IDs in rendered messages
- Chat lines now “Name: message” (ID omitted)
- [join]/[leave] now “[join] Name” / “[leave] Name”
- [rename] now “[rename] OldName -> NewName”
- Welcome now “Welcome Name”
- Init: if already connected, start reading immediately (textarea.Blink + readLineCmd)
- Pre-connect before TUI starts:
- Dial with 3s timeout, read up to two initial lines with 1s deadline
- Seed model with pre-read messages and existing conn
Server:
- IDs now lowercase hex; default username uses ID as-is
- Use strings.CutPrefix for “/name ” parsing
- Add structured logs for join/rename/leave with user, id, and remote addr
UI:
- Simplify chat line format for readability; keep color-coding based on ID-derived color
- Add go-nanoid to generate 6-char per-connection IDs; fallback to RemoteAddr
- Introduce sanitizeUsername with rules: [A-Za-z0-9_.-], spaces→_, trim ._-, max 12 chars
- Support /name <username> to change username with validation and broadcast [rename]
- Greet client with default username user_<id> and usage hint for /name
- Broadcast joins/leaves and messages including username and ID; exclude self on join
- Handle /quit to trigger unified leave flow; consistent leave announcement
- Comment/document broadcast struct, Hub, and startTCPServer
- Increase scanner buffer and add newline-delimited send in broadcaster
Client/main:
- Add flags: -host (default "localhost:9000") and -server (run only server)
- When -server is set, startTCPServer(host) and exit
- Use provided host for client connection
- Center header with width-aware lipgloss styling; adjust padding
Server:
- Introduce broadcast struct {text string, exclude net.Conn}
- Hub.msgCh now chan broadcast; send messages with optional exclusion
- On join: send “[join] …” to others (exclude the joiner)
- Broadcast chat lines without exclusion; newline-delimited as before
- Handle “/quit” by breaking loop (graceful disconnect)
- On leave: broadcast “[leave] …” to all
Refactor notes:
- Remove unconditional embedded server from client startup
- Scanner loop unchanged aside from quit handling and broadcast usage
