Video: Setting Up Vim to Work with Python Applications
Posted byon under
In this short video tutorial I demonstrate my Vim editor setup for working with Python applications.
Do you want to try this out? Download my .vimrc file! If your tagbar does not work, install Exuberant Ctags (use
brew install ctags or
sudo apt-get install ctags, or download from http://ctags.sourceforge.net/)

Thanks for this! I've never heard of tagbar so I may start using it. One thing you might find useful is you can add this to your .vimrc:
This will update gitgutter almost instantly when you make changes to git files.

@Brandon: Hey, I hope you are doing well! Thanks for the tip.

To make your instruction work please note that curl and exuberant ctags need to be installed.
Regards and Kudos for your work!

Thanks for sharing your development stuff! I really like the part that automatically installs vim plug.
Kudos to you!

Thanks for all your work. This is not related to this video but I was wondering if you can help with the Microflack app on this URL https://github.com/miguelgrinberg/microflack_admin. The users' pod keeps crashing and kubectl logs give the following errors. I know its 3 years and many things have changed. Please see if you can help to fix the issues. Thanks
kubectl get logs
users-5d658dff8b-8ch7s 0/1 CrashLoopBackOff 8 17m
kubectl logs users-5d658dff8b-8ch7s

@Damian: it's an issue with the pymsql package and MySQL 8. Use a newer version of pymysql.
#7 Scott said 2020-07-04T11:30:55Z
To get this to work on windows, I installed vim-plug manually and removed the lines relating to vim-plug detection and initial plugin installation. (The need_to_install_plugin blocks)
I tried to see if I could figure out how to modify it so that part would work but couldn't figure out how to do it. I think it's related to how the home directory is specified in windows. But the manual vim-plug installation steps above do work.
Also, @Miguel -- I don't seem to get notified about comments here when my post goes up or a response is posted.
#8 Scott said 2020-07-04T14:14:57Z
Also these guys need to be commented out otherwise weird characters will invade everywhere.
let &t_SI .= "\<Esc>[?2004h"
let &t_EI .= "\<Esc>[?2004l"
#9 Miguel Grinberg said 2020-07-04T14:57:45Z
@Scott: This may not be what you want, but I have used vim under the WSL and Cygwin using the same configuration w/o any issues.
#10 James Gardiner said 2020-07-09T22:22:04Z
Looks very useful -- what triggers the flake/pep test?
#11 Miguel Grinberg said 2020-07-10T08:48:23Z
@James: the syntastic plugin does a syntax check on file save.
#12 Anthony said 2020-07-17T02:30:41Z
Hi Miguel, Thanks once again for a very useful tutorial. I'm trying it out as I want to get better at using vim which I think is really cool. For some reason, it gives a syntax error when I use the new python string format using f"my string". Also how do we get vim to recognise the virtual environment we're in?
#13 Miguel Grinberg said 2020-07-18T14:03:35Z
@Anthony: You may be using an old version of vim, or maybe a vim compiled for Python 2 instead of 3. Vim uses the activated virtualenv by default.
#14 Kevin Luo said 2020-09-26T22:27:09Z
Thank you very much @Miguel Grinberg for the fantastical sharing. But in my environment, the tagbar does not work even thought I have installed the exuberant ctags~;(
#15 Miguel Grinberg said 2020-09-27T13:28:33Z
@Kevin: I'm not sure how I can help. I suggest going over issues in the repository for the tagbar plugin, maybe someone else had the same issue.
#16 Chris Thompson said 2020-12-10T23:04:00Z
Man, this is going to improve my workflow soooo much. I use Vim as my main editor but I only had tabs configured and Kite installed. The rest was all Vim shortcuts. Thank you for sharing!
