elm-react works wonderfully when your entire project is in elm. However, you often embed Elm into a larger application.
index.html will look something like this:
<div id="main"></div> <script src="main.js"></script> <script> var node = document.getElementById('main'); var app = Elm.Main.embed(node); </script>
And you use
But you need to return the elm-make command on every modification of your elm sources. And that's shi... less that optimal for productivity.
But Linux/Unix/whatever can help you there with its
inotifywait command. With it, you can run a command on file modifications.
Go to the directory where your elm sources are and run this:
inotifywait -e modify -m . | while read file; do elm-make Main.elm --output SOME_DIRECTORY_SOMEWHERE/main.js; done
You're telling it to wait for modify events in the current directory. And when it gets them it'll run the elm-make command.
Voila. Edit your elm code and refresh your browser. All is well in the world. Or at least your edit -> compile -> use cycle is shorter. Whatever.
inotify-tools and then you can wait for a file to change using:
inotifywait -m thefile.txt
-m flag monitors the file, instead of exiting on the first event. You can use
-e to wait for a particular event--see the man page.
But you probably want to do something when that happens. You can pipe the output of the command to a bash while loop:
inotifywait -m thefile.txt | while read file; do echo $file; done
file in this case will have the file name and event name, but you don't need to use it obviously.
