Checks uses of undeclared global variables. All global variables must be 'declared' through a regular assignment (even assigning nil will do) in a main chunk before being used anywhere or assigned to inside a function.
|init ()||Enable strict checking for the calling environment|
|lock ()||Prevent creation of new variables in the calling environment.|
|strict_locked (t, n, v)||When the table is locked, __newindex shouldn't be called.|
|strict_newindex (t, n, v)||new global variables are only allowed in main and in C functions|
- init ()
- Enable strict checking for the calling environment
- lock ()
- Prevent creation of new variables in the calling environment. This can be used to detect unwanted usage of globals.
- strict_locked (t, n, v)
When the table is locked, __newindex shouldn't be called. The only valid possibility is when the variable has been assigned nil, in which case it vanishes, and the next assignment will be a new one.
- strict_newindex (t, n, v)
new global variables are only allowed in main and in C functions
