cofan is an http server library for serving files and any other things. You use it to share content in the form of a website. The current classes give you the following:

• Serve the content of a local directory in a form similar to file browser with icons for directories and files based on their extension.

• Serve the content of a local zip file the same way as the local directories.

• List the content of a local directory in json form.

• Serve local html files as a web site.

• Organize your urls in prefix trees.

• Response differently for different ip addresses

It also supports requests of partial files to resume previously interrupted download.

Here is an example of how to use it:

from cofan import *
import pathlib

#our site will be like this:
#   /           (this is our root. will list all the branches below)
#   |
#   |- vid/
#   |  this branch is a file browser for videos
#   |
#   -- site/
#      this will be a web site. just a collection of html files

#lets make an http file browser and share our videos
#first, we specify the icons used in the file browser
#you can omit the theme. it defaults to `humanity`
icons = Iconer(theme='humanity')

#now we create a Filer and specify the path we want to serve
vid = Filer(pathlib.Path.home() / 'Videos', iconer=icons)

#we also want to serve a web site. lets create another filer. since the root
#directory of the site contains `index.html` file, the filer
#will automatically redirect to it instead of showing a file browser
#no file browser also means we do not need to specify `iconer`
#parameter. you can still use it if you want but that would not be very
#useful
site = Filer(pathlib.Path.home() / 'mysite')

#now we need to give prefixes to our branches
#we create a patterner
patterns = Patterner()

#then we add the iconer, filers with their prefixes
#make sure to add a trailing slash
patterns.add('vid/', vid)
patterns.add('site/', site)
#we also need to add our iconer
#you need to tell the iconer about its prefix. by default it assumes
#`__icons__`
patterns.add('__icons__/', icons)

#now we have all branches. but what if the user types our root url?
#the path we will get will be an empty string which is not a prefix of any
#branch. that will be a 404
#lets make the root list and other branches added to `patterns`
#the branches will be shown like the file browser but now the icons will be
#for the patterns instead of file extensions
#we need to specify where the icons are taken from
#the icons file should contain an icon named `vid.<ext>` and an icon named
#`site.<ext>` where <ext> can be any extension.
root = PatternLister(patterns, root=pathlib.Path.home() / 'icons.zip')

#and we add our root to the patterns with empty prefix
patterns.add('', root)

#now we create our handler like in http.server. we give it our patterner
handler = BaseHandler(patterns)

#and create our server like in http.server
srv = Server(('localhost', 8000), handler)

#and serve forever
srv.serve_forever()

#now try to open your browser on http://localhost:8000/

This module can also be run as a main python script to serve files from a directory.

commandline syntax:

python -m cofan.py [-a <addr>] [<root>]

options:

• -a <addr>, –addr <addr>: specify the address and port to bind to. <addr> should be in the form <ip>:<port> where <ip> is the ip address and <port> is the tcp port. defaults to localhost:8000.

args:

• root: The root directory to serve. Defaults to the current directory.
