Keep heading in sync with filename

[armaninux]

I wrote a function to mimic the basic usage of this Obsidian plugin:
Filename Heading Sync

My function:

" keeps markdown heading in sync with filename
function! SyncHeading()
    let @a ="# " . trim(bufname(), ".md", 2)
    1g/^# .*/norm D"ap
endfunction

" merge with ObsidianRename
command! ObsidianMyRenameAndSync execute 'ObsidianRename' | call SyncHeading()
noremap <F2> :ObsidianMyRenameAndSync<cr>

It's crude, but I only have basic skills in vimscripting; it fits my needs and it might be useful to some of you.

Note: 1g/ means it only updates the heading if it occupies the first line in the file. To give it a bit of leeway you might try something like 1,10g/ (checks lines 1 to 10). If you only have one heading, use g/ instead.

To update a misaligned heading, just execute the function: :call SyncHeading().
