Activate indent-blankline in .vimrc

[ivan94fi]

Hi, thank you for the awesome plugin!

I am having troubles with the configuration and I figured this was the right place to ask. I installed indent-blankline with vim-plug in NVIM v0.5.1, but the indentation guides are not active unless I manually activate the plugin with :IndentBlanklineEnable!.

I am using a .vimrc for configuration (not a lua file) so I tried calling the setup function in my .vimrc with something like

lua require("indent_blankline").setup {}

or

lua << EOF
require("indent_blankline").setup {
    show_current_context = true,
    show_current_context_start = true,
}
EOF

These however did not work, so I ended up doing this:

autocmd BufEnter * execute ':IndentBlanklineEnable'

which works as expected, but I feel is not really the right way to go.

So my question is: what is the right way of activating the plugin in a .vimrc file?

You don't have to do any of that, it should just work with no configuration.

Calling IndentBlanklineEnable overwrites all disable checks, that is probably not what you want.
Are you sure there is no other configuration for indent-blankline somewhere in your config?

Ok I was pretty sure there was something not right with my method.

So I tried using this as vim config:

filetype plugin on

" Plugins
call plug#begin('~/.vim/plugged')

Plug 'lukas-reineke/indent-blankline.nvim'

call plug#end()

and opening this python file

import random

def f():
    if random.random() < 0.5:
        return random.randint(0, 234523452345)

with this command vim -u debug_vimrc file.py, but the indent lines are not showing. If I manually execute :IndentBlanklineEnable, the indent lines show up fine.

What could be wrong?

There was a small bug that broke the enable check for Neovim 0.5.1.
I released a fix, it should work now.

But I recommend updating, 0.5.1 is pretty out of date. I try to keep the code backwards compatible, but it is not always possible. You will have problems with other plugins as well.

Yes, I can confirm that the fix is working, thank you.

But I recommend updating, 0.5.1 is pretty out of date

Well, in NeoVim releases page 0.5.1 is marked as released on 27 September 2021, so it is not really really old, but I guess you could call it pretty out of date. Anyway I will follow your suggestion and update as soon as I can. Thanks again.
