New submission from Ilya Grigoriev :
The object `webbrowser.get()` returns has, and had for a long time, a useful
but undocumented field `name`. I wonder if it would be OK to document it as
something like `a system-dependent name for the browser`. This would go here:
https://docs.python.org/3/library/webbrowser.html#browser-controller-objects
The reason I'd like this is so that I can write code like the following:
```python
# In Crostini Chrome OS Linux, the default browser is set to an
# intermediary called `garcon-url-handler`.
# It opens URLs in Chrome running outside the linux VM. This
# browser does not have access to the Linux filesystem. Some references:
#
https://chromium.googlesource.com/chromiumos/platform2/+/master/vm_tools/garcon/#opening-urls
# https://source.chromium.org/search?q=garcon-url-handler
if "garcon-url-handler" in webbrowser.get().name:
webbrowser.open("http://external-url.com/docs.html;)
else:
webbrowser.open("file:///usr/share/doc/docs.html")
```
This would work correctly, even if the user has installed a browser native to
the Linux VM and put it into their `BROWSER` environment variable. I don't know
a better way to achieve the same effect.
Some references to where the `name` field was introduced:
