AFAIK, there isn't, unless you want to go to the trouble of generating a
distinct iabbrev for each of the possible 2^(len({lhs})) - 1 changes.
The generation of all these can be done automatically, as follows (which
needs +float compiled-in).
if has('float')
function GenerateUpCaseAbbbrev(word)
let l = strlen(a:word)
let n = float2nr(pow(2,l)) " number of iterations
let i = 1
while i < n
let from = ""
let j = 0
let k = 1 " 2^j
while j < l
if (i/k) % 2 " i/k is odd
" IOW the (j+1)th bit from right is set
let from .= tolower(a:word[j])
else
let from .= toupper(a:word[j])
endif
let j += 1
let k += k
endwhile
exe 'iabbrev' from toupper(a:word)
let i += 1
endwhile
endfunction
endif
I didn't test this, I wrote it as a kind of exercise in logic. I suppose
you will probably not want to use it. If you still want to, in the case
of the example you mentioned you would write
call GenerateUpCaseAbbrev('integer')
somewhere after the above snippet. To check it, run it (it may be slow,
the inner loop is executed 7 * (2^7 - 1) = 889 times), type
:iabbrev
then duck while Vim throws at you the 127 abbreviations generated (127
and not 128 because I don't abbreviate INTEGER to itself).
The above doesn't check that the function argument is in fact a word
suitable as the {lhs} of an abbreviation, and it assumes (but doesn't
check) that only single-byte characters are used. Correcting these, if
desired, is left as an exercise to the student.
Best regards,
Tony.
