fix(indents): delegate indents for code blocks to treesitter instead of vim

[dtvillafana]

Summary

delegate indents for code blocks to treesitter instead of vim.
This fixes the issue where code blocks are incorrectly formatted for languages that vim does not have indents set up for.

The issue I was having was that the code blocks were not getting formatted according to the injections.scm that is already in the repo.

If you use nvim-treesitter indentexpr for a filetype that is being used in the code block, it should pull that up automatically.

[dtvillafana]

Ah, so this is really an error on my end...
Even so, should it explicitly delegate it?
If it does, it would improve the "out of the box" experience for those who haven't fully configured their indent expressions.

If your indentexpr is correctly set, then yeah. First line in the if statement picks up the indentexpr.
How are you setting your indentexpr?

[dtvillafana]

in my config (generated by nixvim):

vim.bo.indentexpr = "v:lua.require'nvim-treesitter'.indentexpr()"

then later on:

vim.api.nvim_create_autocmd('FileType', {
   pattern = 'org',
   group = vim.api.nvim_create_augroup('org_indent_fix', { clear = true }),
   callback = function()
     local ok, orgmode = pcall(require, 'orgmode')
     if ok then
         vim.bo.indentexpr = "v:lua.require('orgmode.org.indent').indentexpr()"
     end
   end,
})

maybe whatever version of treesitter/org grammar I was using was bad...

relevant files in my config if you wanted to look:

• https://github.com/dtvillafana/nixvim/blob/master/config/org.nix
• https://github.com/dtvillafana/nixvim/blob/master/config/treesitter.nix

You shouldn't need to do this for org, it should automatically happen from here.

What I meant is how do you set indentexpr in your other filetypes, like the ones that you use in your code blocks. For example, if you use lua in your code blocks, how do you set indentexpr for lua?
