Here is function (to parse external scipts, so and serialized vim
dictionaries), that is trying to workaround the limitation of execute.
" Function: lib#source(file)
"Description: create a list, so we can loop over it by using execute
" Args: script to parse
" Return: list
" Notes: (limited usage)
function! lib#source(file)
let list = []
let file = readfile(a:file)
while !empty(file)
let string = remove(file, 0)
if (!empty(file) && match(file[0], '^\s*\') == -1)
call add(list, string)
else
while (!empty(file) && match(file[0], '^\s*\') != -1)
let string .= ' '.substitute(remove(file, 0), '^\s*\', '', '')
endwhile
call add(list, string)
endif
endwhile
return list
endfunction
