fswatch VS watchman

Or even better, fswatch (https://github.com/emcrisostomo/fswatch) which works on Linux, BSDs, macOS, Windows, and even Solaris

If you don’t mind shell shell scripting you can use something like fswatch and some shell logic to do something similar.

Well, I am not too lazy to search but I was interested in your experience, especially with reliability.

This one looks interesting: https://github.com/emcrisostomo/fswatch

What about using https://github.com/emcrisostomo/fswatch ?

The required kernel hooks exist in pretty much any common OS these days, it is a user-space tool that is sometimes missing.

It may not be installed by default, but inotifywait is available in common Linux distributions, usually in a package called something like ionotify-tools, and has been for over a decade-ana-half IIRC. It'll work under WSL on Windows too, though only for ext4 devices not bits of the Windows filesystem made available to Linux.

I can't speak to what other OSs include by default, but as every major OS has a different API for defining how to register a lister and how it gets messages no built-in tool is going to be cross platform. There are third party tools which present more cross-platform consistency, most notably https://github.com/emcrisostomo/fswatch#readme (also available in common Linux distros, just an apt install away in Debian for instance).

fswatch is a cross-platform file change monitor. It will watch any files you specify, then run a script on change.

You can do this without polling using a util like fswatch: https://github.com/emcrisostomo/fswatch

> It watches source files, and regenerates the OpenSCAD files automatically

inotify() is awesome. Here's a library in python that does it.

There's also inotifywatch on linux and fswatch on mac. I'm sure there's alternatives for BSD Unix and Windows, but I care the least about those OS's.

For development it's easy to just ParseFiles before every Execute to be sure you have the latest version. But for production something else is needed, fx watch for changes in files and have this trigger a reload (fx using https://github.com/emcrisostomo/fswatch).

postCreateCommand This section permit to execute a command after the build of the container. I've used this command to execute a script to install Expo and other dependencies like watchman

Facebook open source product: https://github.com/facebook/watchman to get notified when configuration, file or other change

Facebook Meta's Watchman Service looks very useful for watching for changes in files and directories to kick off automation. Still, there seem to be a bunch of gotchas with it that only come to light after trying to mess with it. The docs seem lacking, the Python library needs to be updated, and even the installation on non-Ubuntu or Red Hat distros requires a rebuild, which has been somewhat problematic given the build tools. Also, no official Docker container.

Not to be confused with Facebook’s file watch daemon, which does the same sort of thing but is more complicated. There’s a bunch of tools that integrate Facebook’s watchman for more efficient change tracking.
