Navigate wikilinks

[armaninux]

I wrote a function to navigate between wikilinks with the Tab key. If only one link is present in the files, it will also open it.

I think it would be cool to have something like this as a new feature.

" first, don't move the cursor/don't alter the view
command! -nargs=1 -complete=command Nomove
    \   try
    \ |     let s:svpos = winsaveview()
    \ |     execute <q-mods> <q-args>
    \ | finally
    \ |     call winrestview(s:svpos)
    \ |     unlet s:svpos
    \ | endtry

" checks how many links
function! WikiCountLinks()
    let l:count = 0
    Nomove g/\[\[/let l:count += 1
    Nomove g/\[\[.*\[\[/let l:count += 1
    if l:count == 1
        " one link then open it
        WikiOnlyLink
    else
        WikiGotoLink
    endif
endfunction

command! WikiOnlyLink execute 'norm! /\[\[<cr>:ObsidianFollowLink<cr>'
command! WikiGotoLink execute 'norm! /\[\[<cr>'

" mappings for md files only
augroup obsidian
    autocmd!
    autocmd Filetype markdown nnoremap <silent> <Tab> :call WikiCountLinks()<cr>
    autocmd Filetype markdown nnoremap <silent> <S-Tab> ?]]<cr>
augroup END

that would be really nice! where do I need to put this for it to work?

If you're using an init.vim as your neovim config file, just paste everything in there, it's all written in vimscript.
If you're using an init.lua, you need to translate it to lua script and I honestly don't know how it's done. You need to check a guide about that, for example https://github.com/nanotee/nvim-lua-guide.

Claude came up with a nice Lua version that seems to work for both Wiki style [[link]] and markdown style [text](link) links:

vim.api.nvim_create_autocmd("FileType", {
    pattern = "markdown",
    callback = function()
        vim.keymap.set('n', '<Tab>', '/\\(\\[\\[\\|\\[.\\{-}\\](\\)<CR>:nohlsearch<CR>', { buffer = true })
        vim.keymap.set('n', '<S-Tab>', '?\\(\\[\\[\\|\\[.\\{-}\\](\\)<CR>:nohlsearch<CR>', { buffer = true })
    end
})
