MythStatusScreenlet is a Screenlet for MythTV. Inspiration is from the Mac MythTV Dashboard Widget
The MythStatus Screenlet polls the XML info page of MythTV’s backend (normally port 6544), and parses the XML information to display the status of your backend. It shows the next ten upcoming recordings, highlighting in red, any that are currently recording.
It also shows Last Guide Update status, a disk space graph, Load Average and Temperature as provided by MythTV’s XML status page.
The default theme (MePo) uses the MePo character from the Media Portal project. The MePo character was designed by Glenn Melenhorst and is used with permission. The concept of the MePo theme is from the MePo MythTV theme by zdzisekg.
I have published it on the MythStatus page on the Screenlets website. That page contains a link to gnome-look.org to download the tgz.
Please be nice, it’s my first Python App, my first ScreenLet, and first time I’ve done any rendering stuff in Cairo.
UPDATE2: MythStatusScreenlet v0.0.3 released.
- No longer uses xpath, so should now work in Hardy
UPDATE: MythStatusScreenlet v0.0.2 released.
- Tested on Screenlets 0.0.14
- Now supports MythTV 0.20 and 0.21 xml formats
- Better handling when backend goes away/comes back
I am looking forward to this screenlet!
Looks good!
I hope you release it soon.
Hi Ravneet, thanks for your comments. The screenlet is now available on the MythStatus page on the screenlets website.

Nice screenlet
However, with mythtv-0.21 it does list upcoming recordings, but no other status…
Best regards,
Sune

Hi Sune, thanks for the feedback. I have now fixed support for 0.21.
I’m still running 0.20 on my backend server, so please test the latest release and let me know if you have any more problems on 0.21
Thanks, Net Wolf.
[...] The other widget is actually inspired by the first one. It is called “MythStatusScreenlet” and it is a Linux Screenlet. [...]
well I cannot get it to work, I can’t find all the dependencies it requires: cairo, pango, math, urllib, re, gobject, xml. I have python-cairo, libpango1.0-0, urllib2, python-urljr, python-gobject, python-libxml2. I’ve got screenlets 0.0.12 working on Ubuntu.
oh yah forgot my terminal output

Hi Mr Plow. It appears I have a few xml python bits installed, but it looks like the important one is python-xml
Firstly, running python and determining the file used by xpath.
$ python>>> from xml import xpath
>>> print xpath.__file__
/usr/lib/python2.5/site-packages/_xmlplus/xpath/__init__.pyc
ls -l on /usr/lib/python2.5/site-packages/_xmlplus/xpath/__init__.py reveals that is is a symlink to /usr/share/pycentral/python-xml/site-packages/_xmlplus/xpath/__init__.py
Then determining which packages are installed.
$ dpkg -l | grep -i xml | grep pythonii python-libxml2 2.6.30.dfsg-2ubuntu1.1 Python bindings for the GNOME XML library
ii python-lxml 1.3.3-1 pythonic binding for the libxml2 and libxslt
ii python-xml 0.8.4-8ubuntu1 XML tools for Python
Then get dpkg to list the file in the packages (I just tried them one at a time until I found it)
$ dpkg -L python-xml | grep '/usr/share/pycentral/python-xml/site-packages/_xmlplus/xpath/__init__.py'So, that’s a long winded way of saying, “just install python-xml”. I’ll update the requires list.
Thanks, Net Wolf.
doh, guess Ubuntu Hardy is messing this up

Hi Mr Plow, I’ve now have a Hardy VMware image installed (I am running Gutsy), so will try and look at it this weekend.
From the limited time I spent on it last night, I see that the python-xml in Hardy installs into some “old” dir. I had a quick play around with PYTHONPATH, but had no luck. I suspect I might have to change to one of the newer xpath implementations.
Any progress on xpath so far?
Replace
from xml import xpath
with
from Ft.Xml import XPath
Replace all other appearances of
xpath
with
XPath
I think that’s all I did, but will check back if it doesn’t work. However, I now get a completely blank mythstatus screenlet except for the first short while. Might be some further updates in mythtv at work in that respect…
Best regards and all
@Justin, thanks for your interest. It would appear the other implementations of xpath are much more complicated than the simple one that worked in Gutsy. I was looking at ElementTree, but had come up against a wall. Any suggestions welcomed.
@Sune, thanks for your suggestion. I made your changes, but XPath from Ft behaves quite differently from xml.xpath. Try running screenlets-manager from an xterm to see all that’s going on. I do think it’s a python/xml problem, rather than a mythtv XML format change (I’m still running 0.20 on my backend).
Again, any more suggestions very much welcomed.
I pretty much gave up on xpath/ElementTree, and have written the XML parsing using simple regular expressions. I’ve done a little bit of testing, and it seems to work in a Hardy virtual machine.

It appears 0.0.2 is still only available from gnome-look.org website.
Have you got another URL to grab this from?
I’m running Hardy and 0.0.2 is pretty useless.
Hi Matt, I just downloaded it from Gnome Look, and it is 0.0.3, and there is a VERSION-0.0.3 file inside the tgz.
However, I did notice that in the actual code is still says 0.0.2, so will fix that when I get my dev machine back up and running (although it shouldn’t really matter).
I’ll find somewhere else to host it if you find that you’re getting an old version from Gnome Look.
