Set nosmartindent to avoid comments auto-indenting to first column

[memeplex]

For example, the cursor being ^:

def test():
    ^

say you now type #, you get:

def test():
#

instead of:

def test():
    #

The reason is smartindent. I think your indent plugin should unsetlocal it by default.

[blueyed]

Agreed, without having looked into it.

Should be a trivial change (which should include a test). A PR for this would be welcome, of course!

[blueyed]

I could not reproduce it, using both smartindent and set indentexpr+=#.

(not on master though but while fixing something else)

[hynek]

Closing then. Feel free to re-open if we missed something.

[bharadwaj-raju]

Note that this can fix it without disabling smartindent:

inoremap # X<BS>#

@bharadwaj-raju
So you can reproduce this?
Do you have # in :set indentkeys??

[bharadwaj-raju]

Yes, I can. I don't have # in indentkeys.

Removing the inoremap and adding # to indentkeys re-introduces the problem.

What Vim/Neovim version?
'smartindent' is set, right?
Other settings that might be involved?!

[bharadwaj-raju]

Smartindent is set.

I could still not reproduce it yesterday. Can you try it with a minimal init.vim, please, and provide this here?!

[bharadwaj-raju]

/tmp/minimalvimrc:

set nocompatible

syntax on

filetype plugin on

set smartindent

set smartindent cinwords=if,else,elif,try,except,finally,while,for,def,class

$ nvim -u /tmp/minimalvimrc /tmp/test.py

Reproducible.

[blueyed]

Thanks for the test case.

As we can see it's not caused by this plugin (which I assumed).

From :h 'smartindent':

    When typing '#' as the first character in a new line, the indent for
    that line is removed, the '#' is put in the first column.  The indent
    is restored for the next line.  If you don't want this, use this
    mapping: ":inoremap # X^H#", where ^H is entered with CTRL-V CTRL-H.

Which is what you suggested.

I could imagine adding this to Python buffers via ftplugin/python.vim if smartindent is enabled, but that should be done for Vim by default then probably?!
