Hello,
I like much addTaskCallback() and friends. However, there are situations
were we would like to have a function run BEFORE, not after every
top-level tasks. I think specifically to reset options(width = ) to
accommodate to the current width of the console, using something like:
options(width = system("tput cols"))
I am sure there are many other situations where this could be useful.
Combining tasks run before and after evaluation, one could design a
system to (remotely) indicate when a given R kernel is
starting/evaluating/ending evaluation of some code (with Rpad in mind,
for instance).
How difficult would it be to implement such Tasks run before top-level ones?
Best,
Philippe
