Summary: Error message : translation and management

Initial Comment:
Tcl is often used as a scripting language for users in big  
applications.  
However, users may not speak english - or, more  
generally, the language used in the app to communicate  
with the user may be not english.  
  
I suggest that Tcl should offer a way to handle error  
message in a better way, allowing :  
- at least translation of errors in other languages  
- better : machine-understandable description (such as  
error codes), so that the error message may be  
constructed according to the need, just before sending it to  
the user.  
  
For example, we CANNOT provide english error messages  
in our app. Given the current error management system,  
this seems to be quite a difficult problem to solve...  
  
Pointers for solutions :  
- split of error messages in various parts : static parts (such  
as "Syntax Error", etc.) and variable parts (which give  
details on the error, depending of the context : line number,  
name of the procedure, etc.).  
This is needed to set up a translation system by using  
msgcat, for example  
- generalisation of error codes. In the current version, error  
codes are not set for all the erros.  
  
For details :  
- see news://comp.lang.tcl : quite a large discussion took  
place on the subject, starting from April, 07, 2005, under  
the subjects " Managing (translate) errors in a different 
language " and "Translate error messages" 
- contact me !
