"""Use inotify to watch a directory and execute a command on file change. | |
Watch for any file change below current directory (using inotify via pyinotify) | |
and execute the given command on file change. | |
Just using inotify-tools `while inotifywait -r -e close_write .; do something; done` | |
has many issues which are fixed by this tools: | |
* If your editor creates a backup before writing the file, it'll trigger multiple times. | |
* If your directory structure is deep, it'll have to reinitialize inotify after each change. |
The final result: require() any module on npm in your browser console with browserify
This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.
Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: mathisonian/requirify#5

This code implements a naive JSON writer in C++ complying with RFC 4627. I wrote this as I believe it is a very good example of a real life problem involving lots of C++ constructs. This sample only supports writing JSON and does not support heterogenous ‘object’ serialization and extension are left as an exercice. See Writing json in C++ for some details.
