proc require (public)
Use this method to indicate when some other files (from the same package) are needed to be sourced before the current file. This method is useful in cases where the alphabetical loading order is a problem. A typical use-case is a file defining a subclass of another class. In this case, the file defining the subclass will require the definition of the base class.
- -package (optional)
filename - filename without path and .tcl suffix
proc source_dependent (public)
Source files extending classes of the current file. When classes are defined in this file and (some) of their methods are defined in other files, we have to load the methods of the other files after the classes are recreated in this file (recreation of classes deletes the old methods). Use "::xo::library source_dependent" at the end of a file when the classes are defined.
