In the case of tiOPF, it already prefixes all units with 'ti' and all classes with 'Tti'. The same as what fpGUI does. This reduces the chances of conflicts, so such code can stay the same, especially if that code is used both under Delphi and FPC. My suggestion of namespaces is purely for FPC and FPC compatible code - *not* Delphi. Why, because Delphi namespace support already exists, and will not be implemented as such in FPC. So lets leave cross-compiler projects out of the discussion, because they are a "special" case with different rules. > Now FPC introduces the new namespace system and you'd like to jump the > train and make tiopf "namespace aware".

For FPC only projects, that would be fine with me, and those projects would make a final release before the unit name change (for users that want compatibility without namespaces support). Any future development can then take advantage of namespaces and more logical unit names without ugly prefixes. Just to show how ugly unit names look with prefixes. eg: tiUtils.pas vs tiutils.pas vs utils.pas Under OSes that have filesystems that are case sensitive (like under Linux), the norm is to use lowercase filenames. But with prefixes, it makes such unit names hard to read, and mixing cases make unit names inconsistent and prone to errors. Whereas, if you where free to use a simple unit name without prefixes, you get easy to read and consistent lowercase names.
