Nice! Really does a spectacular job when run on my toy example...
especially when one presses and holds down <F2> key.
But there appears to be a problem with the macro when the
digit(s)/number that define the footnotes (say '3' for footnote [3]) is
also present somewhere in the body of the text - e.g. in a date such as
'1234'.
I think the problem is caused by the '[3]' string yanked via 'va]' being
interpreted as a regex that is a 'collection' whose sole member is the
single character '3'. So that the ensuing '/<c-r>0' (results in '/[0]'
search) looks for all occurrences of the character '3' instead of the
intended ('['+'3'+']') string. This behaviour can be verified
interactively after adding a date such as '1234' anywhere in the body of
the example and doing a '/[3]' repeatedly (as opposed to a '/\[3]').
Here's a version that appears to fix a couple of problems:
:map <F2> G?\[\d\+\]<CR>va]y/\<C-R>0<CR>ndd0Dnhr^llPldt]
^ ^ ^
(a) (b) (c)
a. escape first '[' when searching for '[3]'.
b. added 'n' to skip the first occurrence of '[3]' (the footnote anchor) so the
cursor is back at the beginning of the footnote proper.
c. extra 'l' to avoid deleting the last character at the end of the
footnote.
I don't know if there's a way to run a macro against a bunch of files in
one pass so I may have to to convert the macro to a function that can be
run via :bufdo/:argdo — 700+ files, with some 20-30 footnotes apiece.
Thanks,
CJ
