Prompt only once

[shanto]

I am trying to make the plugin work such that it will only prompt the user for a value if there is no remembered (or previously entered) value. Once the user has provided some input (assume text/password), it will just remember and reuse it till the end of session (or persist the value if it's configured so).

I have tried many combinations of command:extension.commandvariable.promptStringRemember, command:extension.commandvariable.remember and command:extension.commandvariable.transform. I just can't get it work like the above description. Please help with some example.

Addition to the README of the next release:

---

If you need a Prompt-only-once or Pick-only-once in this session you can use the default property of the remember command that specifies a ${promptStringRemember} or ${pickStringRemember} variable. Then use the transform property of the remember command to expand the variable. You have to put the named arguments in the transform property.
