I want to delete any lines that either match ^>$ or >\s

I have something like this, but this doesn't work:nnoremap dq :.,$g/^>[\s$]/d<CR>

Here's a small sample where it should delete the first 3 lines but not the last two (if we are currently at the top line of course):

one way would be to use \| to specify two patterns: %g/^>$\|^>\s/d

    Or :global/^>\($|\s\)/delete (note that :% is the default for :global)

  • extremely weird, but it seems to me, that if I type it in manually it works, if I put it in an nmap it complains that Pattern not found: ^>$|^>\s (for @D.BenKnoble's variant as well, but with of course a slightly different pattern)

    @fbence in a mapping, \| is used to escape a | that would other end the map command start a new one (also written <bar>). So you can write :nnoremap ??? :global/^>\($\<bar>\s\)/delete<CR> or use \v with :nnoremap ??? :global/\v^>($<bar>\s)/delete<CR>. If you put it in a function and call the function from a mapping, you won't have this trouble.
