Zugg Software :: View topic - [2.10] #UNVAR does not handle explicit module or class name

Summary

It is possible to create variables in another module or class (using #var //module/varName value or #var /class/varName value) and reference them (using @//module/varName or @/class/varName) with an explicit module/class name. However, deleting a variable with similar syntax (#unvar //module/varName #unvar /class/varName) fails silently.

Procedure

Open CMUD
Dismiss the sessions window by hitting ESC
Type the following at the command line and hit Enter:

Code:

#module other
Type the following at the command line and hit Enter:

Code:

#var //other/foo bar
#show @//other/foo

The untitled window will display:

Code:

bar

as expected.
Type Ctrl-G to bring up the Package Editor. Verify that the module other contains a variable foo with value bar. Close the Package Editor.
Type the following at the command line and hit Enter:

Code:

#unvar //other/foo
#show @other/foo

Again, the untitled window will show:

Code:

bar

This is incorrect - the var should be gone, there should be an announcement that it has been deleted, and the #show should produce a blank line.
Type Ctrl-G to bring up the Package Editor. Verify that the module other still contains a variable foo with value bar.

The same procedure, using a class name instead of a module name, fails in a similar fashion.

Notes
It is still possible to delete the variable, but you have to use:

Added to bug list.

However, keep in mind that when using #MODULE on the command line, you *must* place the entire script into one command. If you type:

#MODULE other

and press Enter, then when you enter a new command, the current module will actually be reset back to the window that you are typing in.

Yes, I quickly discovered that the command line effectively does a #module 0 at the end of each entry. It didn't matter for this example, so it was cleaner to write the example using several lines instead.
