Dear Gerlando Falauto,
In message 4EB8F762.1030508@keymile.com you wrote:
I tested "env import" with and without -n. Same for "env default". Also tested special variables.
For me, env import is broken now.
I am not able to see how it's obviously broken.
It just didn't work for me.
Perhaps you mean that when you don't provide an argument to -n, the following argument (e.g., -t) is interpreted as a variable name (and therefore consumed)? That doesn't look like an error to me.
Yes, this is a serious bug. Aor design problem.
The whole interface is wrong. I have just extendend "env export" to do a similar thing. The new syntax is:
env export [-t | -b | -c] [-s size] addr [var ...]
We should do exactly the same for "env import", i. e. make the size parameter an option to be passed with "-s size", and pass the names of any variables to import as additional arguments:
env import [-t | -b | -c] [-s size] addr [var ...]
This also greatly simplifies the implementation.
Best regards,
