How would I do that?
Thanks!
Spaces only, or spaces and tabs, or any whitespace including (or not)
no-break spaces and including (or not) CJK wide spaces (U+3000 IIRC)?
Including or excluding the cursor position?
For "true" spaces only, and not including the cursor position, what
about (untested)
if getline('.') =~ '^ \{' . col('.') - 1 . '}'
" we are on the first nonspace, or before it
else
" we aren't
endif
(it is important to use single quotes in the test-expression).
The other cases are left as an exercise to the reader, but beware of the
difference between col() and virtcol()
Also, the example above should intentionally follow the "true" path
whenever we are in column 1, since in that case the zero characters
before the cursor contain nothing that isn't a space.
Best regards,
Tony.
