I am not so sure if LinuxCNC should describe GitHub in too much detail,
but if you see that the one or other reference to some of the many
tutorials of GitHub would have helped then please send another PR to
improve the documentation :)

You mean to the master branch of your fork. That is technically fine,
preferably though you would have committed to a new branch of yours
(basically giving your changes a name) and then pushed that new branch
to your forked repository. This way you can have several developments at
the same time.

I was following
https://www.theserverside.com/blog/Coffee-Talk-Java-News-Stories-and-Opinions/How-to-push-an-existing-project-to-GitHub
and i did ( wow i can go waaay back in the terminal history!)
git push --set-upstream origin barWidgets
long story shorter
i pushed to 'origin' which is my repo on github linuxcnc-barwidgets
i say so because ~/.git/config says
[remote "origin"]
url = https://github.com/tjtr33/linuxcnc-barwidgets.git

The LD_PRELOAD is a trick to override what the C library would normally do.
thanks, i found the library libeatmyfata and code on github

There are tricks to circumvent this with Xnest but I do not feel
competent to suggest how this should be introduced - I admittedly
thought this would have been integrated already.
ah!! i was told that the DISPLAY env var was turned off
in the script 'rumtests'.
I now need to remove the tests/pyvcp-bar
locally(DONE) and remotely(on GitHub TBD)
In will study how to clean up the 'tests' dir in github's 'origin\
I have a small solution for running the graphic tests
but it requires human intervention and evaluation.
I created pyvcptests/ and fill it with barNN.hal and matching barNN.xml.
A script reads that dir, makes a list of the .hal files. Sorts the list
and marches thru the list with "halrun -f barNN.hal"|.
The user/tester must close each window to advance to next.
So, not auotmated but simple.
The wifget is shown on top of the terminal with the xml code visible.
It's meant to 'test' and to teach what the many xnml tags do.

I hope removing the tests dir will not run into same error

You helped a lot.
Thank you

--------------------------------------soem notes of interest
maybe------------------------------------
here's the testbars.py if ii is of interest
/////////////////
import os
import subprocess
import re
def sorted_nicely( l ):
""" Sort the given iterable in the way that humans expect."""
convert = lambda text: int(text) if text.isdigit() else text
alphanum_key = lambda key: [ convert(c) for c in
re.split('([0-9]+)', key) ]
return sorted(l, key = alphanum_key)
files = []
for file_path in os.listdir('.'): # whereami
if os.path.isfile(os.path.join('.', file_path)):
if(file_path.split('.')[1]=='hal'):
files.append(file_path)#only files, no dirs appemed to
'files' list
# sort the list
# from
https://stackoverflow.com/questions/2669059/how-to-sort-alpha-numeric-set-in-python
# halrun each file with .hal extent
for file in sorted_nicely(files):
# display the xml in the terminal, its usually 1 screen
xf=file.split('.')[0]+'.xml'
subprocess.run(['cat', xf])
# show the widget
str = '-f '+file # concatenate switches anf filename
subprocess.run(['halrun', str])
/////////////////
each of the hal files ends with this stanza (makes easy to run next test)
///////////
...
start activate the hal animation ( sioggen pr
random )
waitusr bar01 wait for user to clcik X in widget window
stop cleanup
unloadrt all ""
unloadusr bar01 ""
exit exit to script loop or all done, back to
terminal prompt
/////////
again thanks
