I did one using golang too. https://github.com/shenfeng/http-watcher

It monitors a directory for change (using notify facility provided by the OS), upon change, will execute a given command given by command line arg `-command`. If any browser connected, it will try to refresh the browser too.

        flag.StringVar(&path, "watch", ".", "path to be watched")
        flag.StringVar(&command, "command", "echo", "path to be watched")
I think there may be a mistake?
You might want to update Readme.md too :)

  Usage of eyenotify:
   -command="echo": path to be watched
thanks man! fixed :)
I've been onto this for long just to always forget to fix it. Thanks!
I'm actually developing a node.js application right now and I wondering if there was a easy way to live update my changes instead of restarting my app manually.

This is going to be a great help towards that; props to the author.

You might be interested in nodemon https://github.com/remy/nodemon
I've seen nodemon before and this is what worried me the most:

"nodemon has three potential methods it uses to look for file changes. First, it polls using the find command to search for files modified within the last second. This method works on systems with a BSD based find (Mac, for example)."

Especially on Mac OSX why would you prefer to use an external command like find instead of using Kqueue? I wonder if find is the right tool for that. And I wonder again why only on BSD-based systems when linux also has find.

Gotta read a bit more about that.

fyi, this is how nodemon is doing file checking:

find -L /dev/null -type f -mtime -1s -print

(https://github.com/remy/nodemon/blob/master/nodemon.js#L57)

Or, if you're on OSX using fswatch[1] or on linux inotifywatch[2] along with a simple shell script which kills and restarts your server. Crude, but gets the job done..

Very cool dude.

I hope more OC gets posted to YC, instead of the boring old news articles.

OC?

It'd be nice to have less of those acronyms on HN, it's really not obvious. Maybe because i'm not a native speaker..
It's not really about being a native speaker. It's really just about getting used the "lingo".
And soon everything will be acronyms. What use is it to shorten simple english words?! We already have enough acronyms in IT, we don't need to shorten simple sentences as well.. Isn't OP, TFA, AFAIK, IMHO, etc. enough already?
