Avoid jumping into NvimTree buffer

[n3wborn]

Hi ! Thanks for the time you spend working on portal and sharing this with the community.

I was wondering...

• I'm a big fan of jumplist
• I use NvimTree and have an autocommand that leave nvim when NvimTree is the last opened buffer
• Once I restart nvim, if I leaved it using the autocommand and do jump backward, nvim closes again (after all, that's what I asked with the autocommand)

So my question is:

When jumping forward/backward, is there a way to filter/exclude jumps related to NvimTree filetype/bufname/etc ?

I thought I could do this using builtin and filter but it seems I don't know what I'm doing ^^

Sure thing. You should be able to filter jumps by filtype:

During setup

Apply to all searches (edited for v0.5.0 release).

require("portal").setup({
  filter = function(v)
    return vim.api.nvim_buf_get_option(v.buffer, "filetype") ~= "{ft}"
  end
})

Function call

Apply to a single search.

require("portal.builtin").jumplist.tunnel_backward({
  filter = function(v)
    return vim.api.nvim_buf_get_option(v.buffer, "filetype") ~= "{ft}"
  end
})

I'm not certain what the filetype for nvim-tree so I've left that as {ft} in the examples above. If should be listed in their docs, or you can simply run the following command while focused on an nvim-tree buffer:

:lua =vim.api.nvim_buf_get_option(0, "filetype")

Thanks a lot :)
