Many thanks for your help Benji, both suggestions look useful. I've
been playing around with the first option (as the code _should_ be a bit
neater I think), but I'd quite like to ensure that expandtab is left off
at the end of the insertion (as I'd like to be able to enable and
disable use of CleverTab).
The problem with this is that inside one of the 'if/elseif/else' blocks,
I need to set expandtab, print something into the insert buffer and then
reset expandtab. I'm struggling with this, despite having played around
with lots of possibilities and done what I feel is a fairly
comprehensive trawl of the documentation.
What I've tried:
---
let &expandtab = 1
return "\<Tab>"
let &expandtab = 0 " Never gets executed
---
let &expandtab = 1
feedkeys("\<Tab>", 'n') " Gets executed AFTER the return
let &expandtab = 0
return ""
Try this:
set &expandtab = 1
call feedkeys("\<Tab>\<C-O>:set noet\n", 'n')
