Support for visual selection in lsp_document_symbols

[Infinage]

Is there a way to filter out lsp_document_symbols per visual selection? I am trying out something like this.

nnoremap <leader>fk :lua require('fzf-lua').lsp_document_symbols()<CR>
vnoremap <leader>fk <cmd>FzfLua lsp_document_symbols<CR>

Doesn't seem to work for FzfLua treesitter either.

fzf.lsp_document_symbols({query = get_visual()})

You can get visual like this

table.concat(fn.getregion(fn.getpos '.', fn.getpos 'v', { type = api.nvim_get_mode().mode }))

I am fairly new to lua and vimscript. Is this what you were suggesting?

function getVisual()
  return table.concat(vim.fn.getregion(
    vim.fn.getpos '.', vim.fn.getpos 'v',
    -- { type = api.nvim_get_mode().mode } -- with this set: 'Invalid value for argument type n'
  ))
end

vnoremap <leader>fk :lua require('fzf-lua').lsp_document_symbols({query = getVisual()})<CR>

This doesn't seem to work

you can use this, I'm not sure when getVisual() is evaled.
vnoremap <leader>fk <cmd>lua require('fzf-lua').lsp_document_symbols({query = getVisual()})<CR>

or use

function getVisual(mode)
  return table.concat(fn.getregion(fn.getpos "'<", fn.getpos "'>", { type = fn.visualmode() }))
end

normal mode is expected

Thanks for checking on this. So I tried this and the other suggestion but can't seem to get it to work

lua << EOF
function getVisual()
  return table.concat(vim.fn.getregion(vim.fn.getpos "'<", vim.fn.getpos "'>", { type = vim.fn.visualmode() }))
end
EOF

vnoremap <leader>fk <cmd>lua require('fzf-lua').lsp_document_symbols({query = getVisual()})<CR>

What ends up happening is that the entire selected gets pased into the query box

The other two visual selections work perfectly fine

vnoremap <leader>fs <cmd>FzfLua blines<CR>
vnoremap <leader>fg <cmd>FzfLua git_bcommits<CR>

That’s what’s supposed to happen with query=…, blines ans git_commits limit the range based on the visual selection - there’s no such option for lsp_document_symbols.

Doesn't seem to work for FzfLua treesitter either.

Same answer, treesitter picker also doesn’t limit the range.

Is there another way to achieve visual based filtering for these two?

In general, it would be useful if fzf lua provided an option to supply a post processing function that runs on all fetched results. This would be executed after the underlying process retrieves the data, but before the results are displayed in fzf.

I can attempt to implement this or atleast support for visual filtering of lsp_document_symbols part if you can provide me with some pointers.

You’ll need to implement your own custom picker, you can probably overwrite make_entry.file as most entries goes through that.
