Can't break on textwidth

[snoblenet]

Describe the bug

By default, I can't break long lines using jqG.

I tried changing and deleting the formatexpr. When I do, I can break long lines using jqG, but the result is not indented correctly.

Sample document, before formatting:

* How to Stop an Outdoor Table from Feeling Sticky After Oiling
** Pro Tips
    - *Choose the Right Oil:* Use a quick-drying outdoor oil, such as teak oil or tung oil, designed for exterior furniture.
    - *Clean the Table:* Ensure the table is free from dirt, dust, or old finish before applying the oil.
    - *Temperature and Humidity:* Apply oil when temperatures are moderate (around 50–80°F) and humidity is low for optimal drying.

try this:

-- no change to orgmode's formatexpr
vim.cmd('setlocal textwidth=80')
vim.cmd('setlocal formatoptions=acjnqlt')
gqG

result:

no change

try this:

set formatexpr=nvim_treesitter#formatexpr()
vim.cmd('setlocal textwidth=80')
vim.cmd('setlocal formatoptions=acjnqlt')
gqG

There is a bug with a fallback, so I'll look into that, but from where are you getting nvim_treesitter#formatexpr() ? nvim-treesitter is not exposing that function.

[kristijanhusak]

I pushed a fix that should properly fallback to the internal formatting for the lines that are not affected by the org formatting. Let me know if this fixes it for you.

Thanks.

gqG still does not work.

However, if I do gqap on one paragraph at a time, it works, though I'd expect an extra space before each line following a bullet.

I get this:

I'd expect one more space before or tung oil and before (around 50.

Does it work when you do not use any formatexpr, or the one you provided from treesitter (even though I'm still not sure where it's coming from) ? In your example only headlines are being really formatted by orgmode, rest is being handled by internal formatting.

When the expression evaluates to non-zero Vim will fall back to using
the internal format mechanism.

[snoblenet]

Yes. The three scenarios above were:

1. no change to orgmode's formatexpr
2. set formatexpr=nvim_treesitter#formatexpr()
3. set formatexpr=
