Keeping your web content fresh!
Work in progress....
You'll need to use freshy-chrome-extension in conjunction with this server.
This tool watches for filesystem changes and broadcasts a message to connected clients any time a directory being 'watched' registers an event (creation, modification, deletion). The intended client for this tool is the freshy-chrome-extension, but you're free to write your own if you wish (API coming soon, though the code is fairly short). Currently, the client refreshes the page you're viewing whenever a filesystem event is registered. This is useful when you're working on a web app and don't want to keep pressing ctrl-r.
TLDR; Point this at a directory and open a page using the extension and the page will be refreshed everytime you change something in the directory.
If you have pip you can simply use
$ pip install freshy-server
Otherwise, first clone this repository:
$ git clone [email protected]:/lchi/freshy-server
Then, you'll need the watchdog, twisted and autobahn python libraries, which if you have pip installed is as easy as:
$ pip install watchdog
$ pip install autobahn
$ pip install twisted
I'm using Linux Mint 12, and pip didn't work for twisted on my machine. You can also try:
$ sudo apt-get install python-twisted
For now, the server always binds to port 4444. This will be changed in the future so you can specify where you want to listen. To run, use:
$ python freshy-server.py <directories>
Where specify one or more directories to be watched for filesystem changes. Separate these with spaces. Once the server has been started, you can point your browser to a page running locally using the Google Chrome extension, and this will reload the page when there are changes to a file in the specified directories.
Example:
$ python freshy-server.py myWebAppRoot/ # starts the server, and watches myWebAppRoot and subdirectories for changes
1. Go to your Google Chrome window (with the extension installed).
2. Type the following in the omnibox with <tab> being a tab press: freshy <tab> localhost
3. Watch as the page reloads automatically when the underlying files are changed!
Note that the server doesn't know that the files your watching and the files you're viewing in your browser are related. It just knows where to look for changes, and who is connected.
Ctrl-C to quit.
**NOTE - The server has only been tested on Linux (Mint 12) at the moment, though it should theoretically work across OSX, Windows and Linux. Because the underlying FS event library uses inotify, it is very possible that the tool will not work for Linux Kernels pre 2.6.
Idea for this project was taken from Slushbox, a project by John J. Workman. See the project at slushbox.
