The problem with entr is that: - it's unix only, which, when using a multi-plateform language like python, is limitating - can't be used programmatically without subprocess hacks If you use Python, watchdog is an interesting alternative: - it works were Python works: pretty much everywhere - it uses the best API for the job (e.g: inotify on linux), but will fallback on manual scanning in a thread if the underlying OS has no special file system watcher API - it's a lib that can be use programmatically - it features the command "watchmedo", which is basically what entr does, but with an optional rich file format and plugin system - for simple use cases, all that stuff stays super simple
