Question

Basically the title. I want to have Mini.map disabled for markdown filetype. Tried to add MiniMap.close() in after/ftplugin/markdown.lua but it closes that for all buffers, including rust buffers (but I want to have it enabled for buffers apart from rust too, just not in markdown).

Thanks for the plugin!

Yes, that's the right direction, but it does only half the job: it hides map window when it needs to be hidden. The other part is making sure that it is opened when it needs to be shown.

Here is one way to do it (put this in a regular config files, not filetype script):

-- Define filetypes which need to not show map window
local hide_map_filetypes = { markdown = true }

-- Use `schedule_wrap` to skip some "temporary" buffers
local f = vim.schedule_wrap(function(ev)
  -- Act only if the target buffer that triggered the autocommand is current
  -- This is also to skip some "temporary" buffers
  if ev.buf ~= vim.api.nvim_get_current_buf() then return end

  -- Close if needed, otherwise - make sure that it is open
  local ft = vim.bo[ev.buf].filetype
  if hide_map_filetypes[ft] then return MiniMap.close() end
  MiniMap.open()
end)

-- Act both on `FileType` (when 'filetype' changes) and `BufEnter` (when
-- entering a buffer which already has filetype set)
vim.api.nvim_create_autocmd({ 'FileType', 'BufEnter' }, { callback = f })

Instead of close() or open(), another approach is to set vim.b[ev.buf].minimap_disable = hide_map_filetypes[ft]. This will stop map window from updating and showing the buffer's content, but it will still be visible. This might be a preferred solution if one doesn't want "flickering" map window.
