[GRASS-user] python scripts: printing messages and adding map to tree

GRASS GRASS user

Hi all,

In my python scripts, I want to print some messages during the calculations,
like "step 1 complete". But my 'print' statements only show _after_
the end of the script.
How to make them show during the process?

Also, how to add the resulting map to the tree?

tks

print messages to stderr (or flush stdout), `print >> sys.stderr,
"..."`, better to use `grass.message()`

That's not possible. Please report it as a wish on trac.
