Disable continuation of comments to the next line

[kasshedi117]

vim.opt.formatoptions:remove("o") doesn't work, seems to be overrode by other plugin.

EDIT:

Okay, you were right... and I think your PR is totally valid. Something was overwriting the format options. Credit to this guy here:

• Set global 'formatoptions' that doesn't get overwritten by runtime files neovim/neovim#26885

It was the same ftp plugin, I think referenced by Telescope, which is setting the format options, and I suppose is loaded after init.lua stuff.

If you want a lua-esque version, you can try this instead (note, this might not be the best/correct event to bind to, but it seems to work):

-- disable continuing comments on next line
vim.api.nvim_create_autocmd("BufEnter", {
    group = vim.api.nvim_create_augroup('format_options', {}),
    desc = 'Disable comment continuation on next line',
    pattern = '*',
    callback = function()
        vim.opt.formatoptions:remove({'c', 'r', 'o'})
    end
})

Explain:

There are 2 relevant examples in the Neovim docs

1.)

... working with list-like, map-like, and set-like options through Lua tables: Instead of

set wildignore=*.o,*.a,__pycache__
set listchars=space:_,tab:>~
set formatoptions=njt

you can use

vim.opt.wildignore = { '*.o', '*.a', '__pycache__' }
vim.opt.listchars = { space = '_', tab = '>~' }
vim.opt.formatoptions = { n = true, j = true, t = true }

2.)

These wrappers also come with methods that work similarly to their :set+=,
:set^= and :set-= counterparts in Vimscript:

vim.opt.shortmess:append({ I = true })
vim.opt.wildignore:prepend('*.o')
vim.opt.whichwrap:remove({ 'b', 's' })

The price to pay is that you cannot access the option values directly but must
use vim.opt:get():

You can also refer to the format options table for what the removal of these 3 options does:

fo-c

c Auto-wrap comments using 'textwidth', inserting the current comment
leader automatically.

fo-r

r Automatically insert the current comment leader after hitting
in Insert mode.

fo-o

o Automatically insert the current comment leader after hitting 'o' or
'O' in Normal mode. In case comment is unwanted in a specific place
use CTRL-U to quickly delete it. i_CTRL-U
