fswatch VS adventofcode

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).

Code on GitHub is currently a mess.

In the spirit of the Day 5 ALLEZ CUISINE! challenge to ELI5 (Explain Like I'm Five), here's a tasty explanation of how my algorithm works using only a large bucket of Red Vines and a knife. It says to use lined paper, but if you try this at home consider aligning things on a cutting board.

Bonus solution in Go (golang) because I was confused about why my Elixir solution didn't work and decided to implement from scratch in case I'd done something dumb. The Go one also got the wrong answer, but took less than 100ms instead of a minute, so I could try out lots of tweaks that didn't change the answer.

I spent time this afternoon sprucing up my helpers for the iex REPL. I spent a bunch of time poking at things in IEx the last couple days and wanted to make sure I would minimize keystrokes if I needed to debug things on my phone while drunk. Turns out Thursday night > Friday night > Saturday night in terms of difficulty, so all those macros have so far saved me zero seconds :-)
