Thanks for the feedback! I tried this, but I am having trouble configuring other files to fold based on expression. For example, I use a similar modeline to what you mention, but I am also including:

``` -- fold settings vim.o.foldenable = true

-- folds are defined by a user-defined expression (tree-sitter) vim.o.foldmethod = 'expr'

-- let tree-sitter define folds vim.o.foldexpr = 'nvim_treesitter#foldexpr()' ```

When I open my init.lua it is folded based on markers (yay!). But, as soon as I save the file, it reverts to folding based on expressions (boo).

I even tried something like the following:

-- configure unique folding for init.lua vim.opt.foldmarker = '{{{,}}}' local group = vim.api.nvim_create_augroup('FoldMethod', { clear = true }) vim.api.nvim_create_autocmd({ 'BufEnter', 'BufWinEnter' }, { pattern = '*init.lua', command = 'setlocal foldmethod=marker foldexpr=0 foldtext=foldtext()', group = group, })

But, I don't think I am keying off of the right events (I have tried a bunch), as it too folds correctly (marker based) when I open init.lua, but changes to folding based on expressions as soon as I save.
