I want to create a function that I can call to replace a specific string pattern with
md5sum of current buffer.
I have no experience writing VimL before and can't figure out the way to do it.
This is what I roughly have in my mind:
" Calculate text hash and replace the old one function! HashBuffer() :redir @a " Will this work? Is this a buffer contents or previously save file? :!md5sum % :redir END " replace with @a (How?) %s/%%%HASH.*%%%/%%%HASH-XXXXXXXXX%%%/ endfunction
Let say I have a file, I am working on
# %%%HASH-XXXXXXXXX%%% the content of file .... .... ..
I want the hash to be calculate when I manually
# %%%HASH-1d4171a91c31af2c59acb89a042836e1%%% the content of file .... .... ..
It's obviously not working but I don't have any idea what to do next.
