Startify theme: attempt to index a nil value

[JanValiska]

Hi,

when I configure alpha to use startify theme:

    use {
        'goolord/alpha-nvim',
        config = function()
            require'alpha'.setup(require'alpha.themes.startify'.opts)
        end
    }

I get error on startup:

packer.nvim: Error running config for alpha-nvim: ...ck/packer/start/alpha-nvim/lua/alpha/themes/startify.lua:64: attempt to index a nil value

Any idea how to solve? Thanks

I printed oldfiles using print(vim.inspect(oldfiles)) and what I can say is that in the history there is one non-text(binary) file that I accidentally opened yesterday. Maybe it is needed to handle binary files in the history separately. I suppose that there is missing icon for binary files.

So it looks like problem aren't binary files but files without extension. Since you are matching filename fn:match("^.+(%..+)$"):sub(2) and supposing that there is always match.

Something like this:

            local match = fn:match("^.+(%..+)$") 
            local ext = ''
            if match ~= nil then
                ext = match:sub(2)
            end

solves issue and uses default web-dev icon for files without extension.
