You forgot to set g:myabbrev_set to 0 or 1 in the ToggleMyAbbrev()
function. Easily fixed.
Here is another way to do it, using the new Dictionary type
introduced in vim 7.0. I have not tested this! I also use a single
function, with an argument, instead of three, and I think it makes more
sense to use a buffer-local variable to keep track of the state. This
version has the advantage that if you add an abbreviation, you do not have to
remember to add the unabbreviation in a different place.
let s:abbs = {'then': 'THEN', 'else': 'ELSE'}
" Set action to 's' for set, 'u' for unset, or 't' for toggle.
fun! MyAbbrevs(action)
if (s:action == 's') ||
\ (s:action == 't' && exists("b:myabbrev_set") && b:myabbrev_set)
for [lhs, rhs] in items(s:abbs)
execute 'iabbrev <buffer>' lhs rhs
endfor
let b:myabbrev_set = 1
return 0
elseif (s:action == 'u' || s:action == 't')
for lhs in keys(s:abbs)
execute 'iunabbrev <buffer>' lhs
endfor
let b:myabbrev_set = 0
return 0
else " unrecognized parameter
return 1
endif
endfun
