Many thanks for sharing your config. I found one minor change of the plugin sources:

Plug 'majutsushi/tagbar'
>>> Plug 'preservim/tagbar'

Better update this?

Hi Sir,

How to enable linter on code save in Vim?

@miguelgrinberg
Copy link
Author

@techns27 The linter that I'm using is ALE, and it runs in the background, no need to run it on save.

@Abhishekparas

I am also having the same color scheme but I am not getting that black-ish background as yours, I have that standard background of one dark theme. Can you please help me out and tell what to do because in that background the colors appear so bright.

@miguelgrinberg

Author

@Abhishekparas I'm not sure. In general this is a problem with your terminal configuration and not with the theme. The value of my TERM variable is xterm-256color. If you use a different terminal interface you may see some differences.

Thanks for replying! I will check it out

As soon as NERDtree is on, then :bd or :q closes whole vim, not only the current buffer. When I have several buffers up, this is a problem. However, when I close NERDtree, I can close one buffer at a time using the :bd or :q

Anyone else having this issue?

@miguelgrinberg

@PolyMMA: this is an issue with NERDtree I suppose. I just added a correction to the \x command, which was incorrectly doing :bd. It now works for closing all buffers but the last.

PolyMMA commented Jul 24, 2021

@miguelgrinberg: Thanks for the soulution. Now \x closes the open buffer. Any plans to mitigate the issues with NERDtree?

@PolyMMA NERDtree is not my project, I'm just a user. I don't really have an interest in this, my current set up has a minimum amount of annoyances so I don't have any plans to address it any further.

I Miguel.
Thank you very much for this purpose.
Does your configuration does step by step debugging?
Thank you.

@Pim-tech No. Vim is a text editor, not an IDE. If you need an interactive debugger, use Visual Studio Code or PyCharm, or if you prefer to debug in the terminal, pudb.

How do you like pudb?

Do you use it in your workflow regularly?

@jgarte pudb is my first debugger of choice these days. It's really good.

@miguelgrinberg and Everyone,

I'm getting errors when I run vim with this vimrc.

I only know enough about all of this ... to be dangerous. :) So I'll probably be asking some stoopid questions.

I'm using version 8.0 in the Windows Linux (Ubuntu) shell or app.

At first the errors were from the "if" statement that runs "curl."

I kept getting permission denied when it attempted to create the ~/.vim/autoload/plugin.vim. I tried chaning the permissions on the directories and files but it didn't help. In fact, this is what it looks like now.

hostname:~$ ls -la ~/.vim/autoload/
ls: cannot access '/home/corpmule/.vim/autoload/plug.vim': Permission denied
...snip...
-????????? ? ?     ?        ?            ? plug.vim

I've never seen anything like that.

I also ran the curl command directly from the command line, using sudo. That might be how the above was actually created.

After I edited the vimrc, to move the ! (bang) -- to be directly after the "silent" command, and, put the url on the same line, those errors went away.

silent! curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

But now ... I get more errors...

Error detected while processing /usr/share/vim/vimrc:
line   17:
E117: Unknown function: plug#begin
line   18:
E492: Not an editor command: Plug 'tpope/vim-sensible
...etc

Those "Not an editor command" erors continue through all the lines (plugins) within this function.

If anybody has an idea what I'm doing wrong, or how I could try to fix this, I'd appreciate it.

@corpmule I don't know. I'm not a regular Windows user, but I have used this configuration on WSL occasionally and I don't recall having any problems.

@RandomShtuf I'm not sure, but the error comes from the auto-pairs plugin, so it must be related to that. Unfortunately I'm not an expert in vim plugin internals, so I cannot really help you on this.

oh... thanks anyway... fortunately i was able to fix it... i just had to remove ~/.vim like you did in your video

another quick question tho... is there a way to show dot files/hidden files on the file manager?

@RandomShtuf you can add let NERDTreeShowHidden=1

Hi Miguel. Are you using the default macOS terminal? Does not seem to work properly for me when using the nice onedark theme, no matter the settings. Works fine with set termguicolors and iTerm though. Any ideas on this matter? Thanks!

@mamodrzejewski I use iterm2.

I was try to learn how to NERDtree get message error from ALE Linter and show it on bottom panes in vim. But I am lost…. Thank you Very Much.

@45-4ry I don't think ALE can do that, it checks in the background and adds marks on the lines that have errors. Try the vim-syntastic extension instead.
