You can do something like this.
func! HighlightMatches(substr)$
" Should also be done here:
" 1) Make sure, substr is actually a date
" 2) clear previous highlighting using matchdelete()
try
let cur=localtime()$
let match=system('date --date="'.a:substr.'" +%s')$
if cur > match$
call matchadd('Todo', a:substr)$
endif$
catch
" handle errors
finally
return a:substr$
endtry
endfunc$
Then you can use e.g.
:%s/due:\zs\d\{4}-\d\d-\d\d/\=HighlightMatch(submatch(0))/g
There doesn't seem to be a way to have Vim create a date for a given
string, so I had to use the shell's date command. Unfortunately, because
of using system() one cannot use the 'n' flag, because this is not
allowed in the sandbox.
All in all, this would make a nice plugin.
Best,
Christian
