Comment (by Charlie):
also, is it possible to use a variable in this expansion function ?
I need to display a frame number with an integer offset I calculate
before:
{{{
text=%{expr\\\\\:n-' + offset + '}
'text=%{expr\\\\\:n-%d}' % offset
}}}
Both lines above display the plain expression 'n-offset', but don't
calculate it.
Thanks in advance
