Determining an operating system's default browser

[John McMonagle]

Is there a python module which can determine an operating system's
default web browser application.

I would like to use it in the following context: I have a GUI
application where all the documentation is written as html pages. I
wish to have these html help pages open in the default browser when
selected from the application's Help menu

If python can determine the path to the default browser, I can then just
spawn it.

Regards,

John McMonagle

You don't have to determine it. Just os.startfile('p age1.html')
and let the OS figure it out.

Note that this only works on Windows.

Works great for Windows - not available on Unix though.

I think the htmlview command is used for this purpose (displaying html
documentation of applications) on many Linuxes. So you could try
os.system('html view'). Given the variety of Unixes (and even Linuxes)
out there this is not a general solution.

So I would try htmlview first. If it does not work, the program could
ask the user for his favourite browser the 1st time he looks at docs,
and save this to a configuration file.

The module webrowser module does this - and I use it for exactly this
purpose. :-)

Take a look at the desktop module for similar functionality for KDE,
GNOME and the Mac OS X desktop environment (as well as Windows, of
course):

Take a look at the desktop module for similar functionality for KDE,
GNOME and the Mac OS X desktop environment (as well as Windows, of
course):

Note that those do not, of course, work on all Unices.

On my machines, there is One Correct Way of doing these things, and that's
to look in the MIME support/configuration files (~/.mailcap, and so on),
first for the user, then system-wide. Something there might tell you what
program should handle text/html content.

This mechanism is widespread under Unix, I think ... but I don't know if
there is a general interface to it, or a Python interface.

Correct: they work only for the stated desktop environments.

Indeed. Thanks for reminding me about mailcap/metamail - I used them in
a project about ten years ago, and I suppose not having any
opportunities to use them in the intervening period probably pushed
them to the back of my mind.

Here's an example:

import mailcap
command, entry = mailcap.findmat ch(mailcap.getc aps(), "text/html")

Here's another more comprehensive set of examples:

Sadly, when considering my KDE desktop's default browser, inquiring the
application for HTML files yields Mozilla Firefox from my mailcap file.
What I've discovered is that the issue of an URL-opening application is
often quite separate from an appropriate application to open a file of
a given type. Perhaps I should call desktop.open something like
desktop.urlopen instead, since that name arguably describes the purpose
of the function more accurately.
