[Zim-wiki] Diagram Editor not working on Windows 7
Hi,
I'm new to this mailing list. Found it from Zim homepage following
For user questions and development discussion, please join the
mailing list..., Hope this is the right place for this mail.
I've been using *Zim 0.59* on a *Windows 7 64bit* machine for a while
now, but only with a few pre-installed plugins enabled. When I wanted
to draw some block diagrams in my wiki's a couple days ago, I
downloaded *GraphViz 2.30.1* (with its *bin* directory added in my
PATH variable) along with *Pango 1.29.4-1* and enabled *Diagram
Editor* plugin in Zim Preferences view. But the plugin didn't work.
1. In Insert Diagram dialogue, an error icon is displayed in the
preview area when I click on the Preview button. When I click on the
OK button, it says An error occurred while generating the image. Do
you want to save the source text anyway?.
2. I confirmed that the dot command from GraphViz is working as
expected when I type it in a command line interface (both cmd.exe and
MSYS shell are tested).
3. Following is a piece of GraphViz code I tested with:
digraph G {
foo - bar
}
4. I googled around and got nothing useful.
So I'm wondering,
1. Did anyone see this problem before?
2. I can't find a log file anywhere, is there one? Or is there a
switch to enable/disable logging?
3. In .../zim-0.59/App/ZimDesktopWiki/zim/plugins/diagrameditor.py,
line 107, I found:
# Call GraphViz
try:
dot = Application(dotcmd)
dot.run((self.pngfile, self.dotfile))
except ApplicationError:
return None, None # Sorry, no log
else:
return self.pngfile, None
Is that except clause the right place to trace down the problem? (I
don't know Python, sorry!)
I found that every .py file in that directory has a .pyo version,
they seem to be compiled Python modules?
I don't have a Python compiler/runtime. If this is not a known issue
or there's not a known solution for it, I'm gonna install one and
start to learn some Python. I really love Zim for its simplicity and
extensibility and its file system hierarchy for storage.
Thanks in advance, and best regards,
Bagana

Just tested using source version of zim on windows 7 with Graphviz 2.21
installed. Works as expected.
Not tested:
- compiled version of zim
- GraphViz 2.30
2. I can't find a log file anywhere, is there one? Or is there a
switch to enable/disable logging?
The logging from zim can be found in %TM%/zim.log, to get detailed debug
output use zim -D --standalone. The log will include a line where the
dot command is executed, but not output from the dot command. Please check
this log for any bugs in zim itself (before calling dot).
3. In .../zim-0.59/App/ZimDesktopWiki/zim/plugins/diagrameditor.py,

# Call GraphViz
try:
dot = Application(dotcmd)

return self.pngfile, None
Is that except clause the right place to trace down the problem? (I

Well, yes, but you don't have much info at that point since the dot command
does not generate a log. You can add a statement before return None, None
like:
except ApplicationError:
import logging
logger = logging.getLogger('zim.plugins.diagrameditor')
logger.exception('Error running dot:')
return None, None # Sorry, no log
This will add any information that can be obtained to the log. But might not
be very informative.
(be aware that python is sensitive to indenting level, so put is at the
proper depth)
I found that every .py file in that directory has a .pyo version,

Yes, but don't worry, they are regenerated when the source is edited - no
need to compile anything yourself.
I don't have a Python compiler/runtime. If this is not a known issue
or there's not a known solution for it, I'm gonna install one and

extensibility and its file system hierarchy for storage.
Actually you have :) it is compiled in the zim executable you have .. but
separate version is indeed easier for debugging.

Re: [Zim-wiki] Diagram Editor not working on Windows 7
that Todd described, because the
code path taken in subprocess.py then use CreatePipe for the `p2cread`
variable on which `DuplicateHandle` is called.
--- end of quote ---
I don't know what that means, but I tried to start zim.exe from
Explorer and ... (Y^^Y) I worked!
However, throwing exceptions when it's launched from command line is
still a bug I guess?
Is your Windows 7 32bit or 64bit? Mine is 64bit, this could be the reason?
