No, there are no such shortcuts. Nearly equivalent:
for letter in map(range(char2nr('0'), char2nr('9'))+
\range(char2nr('a'), char2nr('z'))+
\range(char2nr('A'), char2nr('Z')), 'nr2char(v:val)')
...
endfor
I would say that is a pretty good short cut and exactly what I needed.
Why do you need this?
For the YankRing plugin
(http://www.vim.org/scripts/script.php?script_id=1234) I want to
optionally display all the numbered and lettered registers in the window
and allow the user to choose from those as well. The FOR statement
allows me to easily iterate through the registers and display them.
Something like this:
for letter in map(range(char2nr('0'), char2nr('9'))+
\range(char2nr('A'), char2nr('Z')), 'nr2char(v:val)')
YRDisplayElem(letter, getreg(letter) )
endfor
I never remember the map() function, but I still wouldn't have come up
with the char2nr stuff.
Much appreciated.
Dave
