Picker for file's table of content

[avidseeker]

Thank you for the cool plugin.

To fzf a markdown table of content, it's as simple as :FzfLua blines then grepping ^#.

• Is there a way to create a specific picker specifically for markdown files? i.e: I want a shortcut for something like :FzfLua blines_md that would automatically grep out headers.
• While this simple solution works, I wonder if there's a general solution (perhaps based off treesitter?) to fzf the outline of any given file: like python, lua, and other file types. If possible, that would be really awesome and would render plugins like https://github.com/hedyhli/outline.nvim as obsolete for me.

If you want to grep header... gO can put them in a loclist, which call vim.lsp.buf.document_symbol()
For markdown file it based on treesitter though (https://github.com/neovim/neovim/blob/28eaec5e1526b2a004eadeadf6246df75cfa08e8/runtime/lua/vim/treesitter/_headings.lua#L87).

You can use FzfLua lsp_document_symbols as long as you have lsp.
There's also a FzfLua treesitter, instead add new picker we can improve it

I see this comment: https://github.com/neovim/neovim/blob/28eaec5e1526b2a004eadeadf6246df75cfa08e8/runtime/lua/vim/treesitter/_headings.lua#L87.
Maybe someday upstream will have similar thing like aerial.scm https://github.com/stevearc/aerial.nvim/blob/75de06f8edbd0006997a19b760045753d4f6693c/queries/markdown/aerial.scm.

And there already a require('aerial').snacks_picker(), it's also an option to contribute to there or make a custom picker, it's not that hard we can check how it implemented.

EDIT:
Add it here: phanen/fzf-lua-extra@230d56c

A lsp server feels like an overkill for something as simple as a single self-contained markdown file.

Not sure why FzfLua treesitter is not showing anything for me. I made sure treesitter for markdown is loaded. Maybe there's a specific treesitter option I'm missing?

The suggested picker is very specific, not something I’d add as a permanently maintained picker in fzf-lua, if you want just headers why don’t you use :lua FzfLua.grep({ search = "^#”, no_esc=true }) (or query= if you prefer the blines version)?

If this doesn’t meet your needs copy the blines code and create your own custom picker.
