How to install this with vim

[amandeepgautam]

Hi, I found the discussion hard to follow. I want to use cxxd with its accompanying vim plugin. Can you please outline the steps what needs to be done.

@JBakamovic I did that but it gives the following error:

I am ssh'ing to a remote machine and using vim (just in case it matters)

It has python3 support compiled in but python seems not. You can try removing has("python") check from plugin/cxxd.vim at line 14 but I am not sure if it is gonna work or not. I haven't tested this combination.

[amandeepgautam]

@JBakamovic I removed has("python") check from plugin/cxxd.vim. Additionally, I had to change cxxd/server.vim to use import statements like

python3 import os, sys, vim python3 sys.path.append(vim.eval("fnamemodify(fnamemodify(expand('<sfile>:p:h'), ':h'), ':h')") + os.sep + 'lib') python3 server_handle = None

However, changing the following: python import cxxd.api to python3 import cxxd.api lead to this exception: Error detected while processing /home/cohesity/.vim/plugged/cxxd-vim/plugin/cxxd/server.vim: line 10: Traceback (most recent call last): File "<frozen importlib._bootstrap>", line 2218, in _find_and_load_unlocked AttributeError: 'module' object has no attribute '__path__' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<string>", line 1, in <module> File "/home/cohesity/.vim/plugged/cxxd-vim/lib/cxxd/api.py", line 1, in <module> from server import ServiceId File "/home/cohesity/.vim/plugged/cxxd-vim/lib/server.py", line 1, in <module> import cxxd.server File "/home/cohesity/.vim/plugged/cxxd-vim/lib/cxxd/server.py", line 4, in <module> from parser.cxxd_config_parser import CxxdConfigParser ImportError: No module named 'parser.cxxd_config_parser'; 'parser' is not a package

Keeping this as it is: python import cxxd.ap gives the old error: python import cxxd.api line 15: E319: Sorry, the command is not available in this version:

Any suggestions to fix this? Any plans to support this configuration in future?

[JBakamovic]

Given that Python2 support is EOL by the end of this year, I guess I will have to consider porting whole implementation to Python3. But honestly I've been very time-constrained for the past few months and will be for upcoming ones so I am not sure if I am gonna be able to find a free time-slot. So, any contribution would be welcome of course :)

[amandeepgautam]

@JBakamovic not sure how much time I have for myself, but will give it a try. This project seems promising(I am not sure if anyone out there provides such functionality). Any pointers to getting started?

[JBakamovic]

@amandeepgautam There is a utility, 2to3, which is ought to automate Python2 to Python3 transition. See here.

I would approach the process with following steps:

1. For each .py file in the project:

• Run 2to3 on it (e.g. 2to3 -w api.py).
• Run unit-test suite to verify that things are not broken (python3 tests/run_unit_tests.py).

2. Once unit-test suite is running with applied changes, verify that integration-test suite is also working (python3 tests/run_integration_tests.py).

As you can see, it looks pretty much straightforward but I guess that some steps will require some plumbing around. Let me know if you get stuck anywhere, I will be pleased to help.

Hi, I am interested about cxxd. Is this python-related problem still a thing?

[JBakamovic]

Yes, transition to python3 is still WIP. I've got a hacked version of it though and I'm keeping the changes in migration_to_python3 branch. Merging it with master will require some polishing for which I haven't found any spare time yet.

[JBakamovic]

With c541f8a8 python3 transition has been completed.
