Having issue with specific symbols about gf_kernel HOT 29 OPEN

I can't reproduce the problem. For me it works as expected:

But I use Linux (and don't have a Windows machine available for testing).
Do you have a minimal example that causes the problem?
Does the command line in which you started Jupyter show any error messages?

from gf_kernel.

I use Windows and I think the problem is because of that.
About the examples: p -lang=1 "a ⤔ b" | l -treebank, p -lang=Formal "b ≠ a" | l -treebank, ... any operators except '+','-','=',...just keep running with no output.
This is the output from command line:

from gf_kernel.

This seems to be a Windows-specific bug. Apparently it defaults to using the CP-1252 encoding.
Anyway, I now set it to UTF-8 and hope that it fixes the problem.
Can you pull the most recent version of the GF kernel and it install it to see if it works now?

from gf_kernel.

I pulled the most recent version of the GF kernel and still it doesn't recognize specific symbols. But now it doesn't generate any output but stop running.

Is there a way that I manually change the related files?

from gf_kernel.

Unlike before, it now halts during execution but without producing any output.

from gf_kernel.

What happens if you try to parse (without linearization)?

from gf_kernel.

For example for this command: p "a ⤔ b"
generates this error:
The parser failed at token 2: "\915\241\246"

from gf_kernel.

Okay, I've tried to specify the encoding in more places. Could you please install the newest version one more time and see if it works now?

from gf_kernel.

I got the new version, but the kernel doesn't work again, although I checked the line '22' (now is in line 21) in the file GFRepl and it references to the address of gf.exe. Did you add UTF-8 encoding to that line too? maybe that's why the gf kernel doesn't start again.

from gf_kernel.

Ah, yes, I forgot that that's still an issue.
I added the encoding there as a command line argument to GF. It should have two arguments now: , '--run', '--coding=utf8', instead of just , '--run'.

from gf_kernel.

Will you release the new update soon? I was using gf-kernel and after getting the new version the kernel stoped working.

from gf_kernel.

I could undo the changes, but then the unicode symbols won't work.
What is your line 21 in GFRepl.py?
It should be something like

        self.gf_shell = Popen(('C:\\Users\\fatemeh\\gf-3.11-windows\\gf.exe', '--run', '--coding=utf8')

If it's that line and it doesn't work for you, then I will undo the changes and Unicode symbols unfortunately won't work on Windows until I find a different solution.

from gf_kernel.

I've now managed to get Windows in VirtualBox and the most recent version does work for me there (assuming that line 21 in GFRepl is changed correctly)

from gf_kernel.

This is the line number 21: self.gf_shell = Popen(('C:\Users\fatemeh\gf-3.11-windows\gf.exe', '--run', '--coding=utf8'),
stdin=PIPE,
stderr=self.pipe[1],
stdout=self.pipe[1],
text=True,
encoding='utf-8')

from gf_kernel.

Did you release new updates?

from gf_kernel.

The problem might be that you use single backslashes. Can you try 'C:\\Users\\fatemeh\\gf-3.11-windows\\gf.exe'?
I haven't released a new update because I think that this should work

from gf_kernel.

I tried with single backslashes and it still doesn't work. I don't think backslashes make problem, since before kernel was working with double backslashes too.

from gf_kernel.

I mean that in the line you copied, you used single backslashes. It has to be double backslashes.
If it doesn't work with double backslashes, what errors do you get in the command line where you run jupyter notebook?

from gf_kernel.

I got the gf-kernel again, and tried with both single and double backslashes. Unfortunately doesn't work.

Ah, in the error messages it shows that line 21 wasn't update:
self.gf_shell = Popen((find_executable('gf'), '--run', '--coding=utf8')
Did you run
python3 -m install .
in the gf_kernel directory and then
python3 -m gf_kernel.install?
My guess is that you forget one of those (happens to me all the time)

from gf_kernel.

I got it with these commands:
git clone https://github.com/kwarc/gf_kernel
cd gf_kernel
pip install .
Should I run any other commands?

from gf_kernel.

Yes, one more: python3 -m gf_kernel.install

from gf_kernel.

I did. But nothing changed.

Somehow the installed kernel does not get updated. Maybe you have different python installations and it gets installed for the wrong one.
The other option would be that you open the file C:\Users\fatemeh\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\gf_kernel\GFRepl.py and change line 21 there.

I changed the GFRepl in the address you mentioned. Now the Kernel works but still can not detect the operators. Thank you for your help, may be it's better to use the text editors to write my gf codes and run them in the gf shell, since operators can be recognized there.

from gf_kernel.

In between yes, I have two python installation.

That's a pity - but then running them in the GF shell might really be the better option. I thought it would work now.
I'll let you know if I find any other ways to make it work with the Jupyter kernel.

Thank you!
