Lauch default editor (like 'webbrowser' module)

Question

Is there a simple way to lauch the systems default editor from a Python command-line tool, like the webbrowser module?

Answer 1

Under windows you can simply "execute" the file and the default action will be taken:

os.system('c:/tmp/sample.txt')

For this example a default editor will spawn. Under UNIX there is an environment variable called EDITOR, so you need to use something like:

os.system('%s %s' % (os.getenv('EDITOR'), filename))
