Libraries & Namespaces

[Stefan Brantschen <sbr@...>]

I guess every Lua programmer has a plethora additional utilities for,  
say, strings or tables, that complement the standard libraries for  
these types. Obviously, I have two basic possibilities to make these  
additional utilities available, either adding directly to the global  
'_G.string' or '_G.table' tables, or to create my own namespaces,  
such as 'string2' or 'table2'.

As long as I do my own, private thing, it does not really matter, and  
I might be tempted to add to the existing global namespaces, so that  
_all_ table-utilities are uniformly accessible via 'table.some_util 
()' and so on. However, based on my background, I'd rather use  
separate namespaces for additional libs, just to avoid possible  
conflicts.

I was wondering how you experts are handling this. Note that I am not  
asking for anything normative, as I don't expect something of this  
sort to exist in the liberal Lua world. :-) I kindly ask for personal  
prefs and habits, or possibly company-local guidelines.

Thanks and regards
