I have the following line:
return err
And would like to replace that to:
return fmt.Errorf(": %w", \1)
Which is done easily with something like:
:s/return \v(\k+)/return fmt.Errorf(": %w", \1)/
The problem with this is that after the :s my cursor position will be at the start of the line (the r in return), while it would be much more useful to place it on the :.
Is there any way to set the cursor position in the substitute replace pattern?
Unfortuately, that's not possible, but hey, vimscript is here to help you:
function! Sub(search, replacement, flags)
norm!^
let pos = searchpos(a:search, a:flags.'n')
exe ':s/'.a:search.'/'.a:replacement.'/'.a:flags
call setpos('.', [0] + pos + [0])
endfunction
This function acts exactly like :s/.../.../... except it leaves your cursor on the replaced part
It's not perfect, especially if you're used to type :s/.... to replace, but It gets the job done
:scommand, using a sub-replace expression, that calls a function\=MyReplacethat drops a mark anywhere on the pattern and the command would then after successful substitution move to that mark. Sounds complicated :/
