Ubuntu, could not load xcb, problems with libz.so
by Kevin Dalley
It looks like the artisan packaged for Ubuntu doesn't quite work, at
least on my machine, which is Ubuntu-17.04.
But I don't think that it is my machine.
I installed the Ubuntu package artisan-linux-1.0.0_amd64.deb
And received this message:
kevin@awabi:~$ artisan
This application failed to start because it could not find or load the
Qt platform plugin "xcb".
Available platform plugins are: xcb.
Reinstalling the application may fix this problem.
Aborted (core dumped)
Then I set:
export QT_DEBUG_PLUGINS=1
and repeated:
Got keys from plugin meta data ("xcb")
loaded library
"/usr/share/artisan/Resources/qt_plugins/platforms/libqxcb.so"
QLibraryPrivate::loadPlugin failed on
"/usr/share/artisan/Resources/qt_plugins/platforms/libqxcb.so" : "Cannot
load library
/usr/share/artisan/Resources/qt_plugins/platforms/libqxcb.so:
(/usr/share/artisan/libz.so.1: version `ZLIB_1.2.3.4' not found
(required by /usr/lib/x86_64-linux-gnu/libpng16.so.16))"
This application failed to start because it could not find or load the
Qt platform plugin "xcb".
Available platform plugins are: xcb.
Reinstalling the application may fix this problem.
Aborted (core dumped)
Now, I examine the libz.so, and it looks like it is a different version
than expected.
kevin@awabi:~/src/artisan/src$ strings /usr/share/artisan/libz.so.1|grep
ZLIB
ZLIB_1.2.0
ZLIB_1.2.0.2
ZLIB_1.2.0.8
ZLIB_1.2.2
ZLIB_1.2.2.3
ZLIB_1.2.2.4

That error indicates that the script to be run could not be found. Did you specify the full path in the Device Assignment dialog like
/Users/luther/Desktop/test.py
Next version will allow for ~ expansion to a users home directory like
~/Desktop/test.py

That is just a warning having to do with different lib versions and can be ignored.

Just tested on Mac OS X and everything works as expected.

Could you first test with a simple script like:
--
#!/usr/bin/env python
print ("237.1,100.4")
--
saved as test.py and made executable with "chmod +x test.py"?

Error loading external Python files
by Sean Boyce
Hello,
In recent versions of Artisan (including 1.0.0) , I am unable to use
external python files to send data to Artisan (through
Device-->config-->Prog). I am using artisan 1.0.0 installed from 64-bit
.deb package.
The error I get in Artisan is:
Exception: callprogram(): [Errno 2] No such file or directory @line 29561
When running Artisan from a terminal (to get additional error messages), I
see the following message repeated over and over:
bash: /usr/share/artisan/libtinfo.so.5: no version information available
(required by bash)
I am running Ubuntu Linux 16.04. A similar problem appears to occur on
MacOS but I can't confirm it is exactly the same presently.
The python file in question prints to stdout using a python print
statement, works correctly outside of artisan, and was used with previous
versions of artisan. The only module it imports is serial.
Is this a bug? If so, is there any diagnostics I can provide to help fix it?
Best,
Sean

Artisan 1.0.0 (6)
by musmannsvej＠gmail.com
Is it correct that the alarm action ”Call Program” only can Work with Windows Batch files ? and not Phyton script files or VBS files ?
I am having the problem that I am getting the ”DOS window” in the middle of Artisan and it is quit annoying.
Best regards

Re: [Artisan-user] Slider Event, Multiple Placeholder
by Marko Luther
Brad,
the {} is an unnamed string format placeholder in Python that is supplied by Artisan with one argument. A command like this
write([10,0,{0}/100],[5,5261,{0}])
reusing this first argument in two places should work as expected.

Slider Event, Multiple Placeholder
by Brad Bradshaw
If possible I would like to write 2 modbus devices simultaneously, a VSD
and an LED display. However I don't seem to be able to use the {}
placeholder twice in a slider event,
So a command like this;
write([10,0,{}/100],[5,5261,{}])
It's not essential, but would be nice to see if I left the power on when I
close Artisan. Here's a link to the display

stop smoothing to ROR on save
by Steve Egge
I've played with the settings . esp on the "Extras" . I can't easily seem
to find it
How do I stop the additional "smoothing" of the RoR curve when I save it .
so it looks like it did when I roasted it . can't seem to find the magic box
to uncheck or setting to change.
Thanks . Steve Egge
