Extra; Options no longer opens

[Graham Harris]

Hi,

suddenly, I can no longer get to the Extra; Options menu.

At the same time I get this new error sequence on

ImportError: /usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_html2.x86_64-linux-gnu.so: undefined symbol: wxEVT_WEBVIEW_NAVIGATED
Traceback (most recent call last):
  File "lib/pwiki/PersonalWikiFrame.py", line 1995, in <lambda>
    _(u'Set options'), lambda evt: self.showOptionsDialog(),

...

There were some updates to Python pushed out to Linux Mint 18 (Ubuntu Xenial; Debian) repositories today,
python-apt (1.1.0~beta1build1) to 1.1.0~beta1ubuntu0.16.04.1
python-apt-common (1.1.0~beta1build1) to 1.1.0~beta1ubuntu0.16.04.1
python3-apt (1.1.0~beta1build1) to 1.1.0~beta1ubuntu0.16.04.1

However, reverting to the 1.1.0~beta1build1 versions of each of these three doesn't immediately seem to fix it. I will try a reboot and get back to you....


The most recent change to wx was on 11 January:
Installed the following packages:
libwxbase3.0-0v5 (3.0.2+dfsg-1.3ubuntu0.1)
libwxgtk3.0-0v5 (3.0.2+dfsg-1.3ubuntu0.1)
python-wxgtk3.0 (3.0.2.0+dfsg-1build1)
python-wxversion (3.0.2.0+dfsg-1build1)

update: rebooting doesn't fix it either. The more complete error message is:

ImportError: /usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_html2.x86_64-linux-gnu.so: undefined symbol: wxEVT_WEBVIEW_NAVIGATED

I do have a file ~/bin/WikidPad2_3beta16/user_extensions/pygments/lexers/web.py .

Anyone got ideas please?

I think the problem is that pygments is not "officially" installed. Now the
pygments contained in the PrettyCode plugin searches for additional lexers to
support even more languages, finds one for mako which in turn tries to import a
part of pygments which can't be found and fails.


As a solution you should first of all in "user_extensions" delete the file
"__init__.py" and (if present) "__init__.pyc", "__init__.pyo" as well as the
whole "pygments" subdirectory. If you have modified some of the files you should
of course keep copies of them.


From

https://github.com/WikidPad/Accessory-PrettyCode/releases/tag/PrettyCode-20170308-py-2.6

download "PrettyCode20170308_py2.6_basedOn_pygments2.2.0.zip" (actually the
version was meant to be 20180308, I made a typo) and place the file AS IT IS
(without unpacking) in "user_extensions".

Since 2.3beta08, WikidPad can handle plugins in ZIP-files.


This new version of PrettyCode doesn't search for additional lexers anymore.

Thanks Michael, that did indeed fix the problem.
