feat(watch): add hb watch command for auto-push on file change - #42
Merged
Conversation
Adds `hb watch [<file>]` and `hb watch --dir <dir>` to monitor local Markdown files with fsnotify and push changes to Hatena Blog automatically after a configurable debounce delay (default 500ms). Graceful shutdown is handled by signal.NotifyContext (SIGINT/SIGTERM). pushFileFunc is exposed as a package-level variable for test injection.
- Use cmd.Flags().Changed("dir") instead of dir != "." for mutual
exclusion check so that explicit --dir . is also detected
- Stop all pending debounce timers before returning on ctx.Done()
to avoid goroutine leaks after shutdown
- Set cmd context from runWatch so pushFile can propagate cancellation
to push subcommands
- Guard AfterFunc callback with ctx.Err() check
- Add TestWatch_Debounce to verify rapid saves produce only one push
