Logged In: YES user_id=79902 Here's a version with a better API jenglish added on 2003-08-19 03:21:07:

Couple notes on the API --
namespace ensemble create ?cmdName? ?-option value ...?
could be replaced with
namespace ensemble create ?-command cmdName? ?-option value
...?
since currently [namespace ensemble create -command foo] is
an error ("-command is read-only").
The -unknown handler could (should?) use the TIP 90
-returncode / -returnlevel mechanism; that way the ensemble
command can distinguish a TCL_CONTINUE meaning "reparse"
from a TCL_CONTINUE that the resolved command returns. I'd
also suggest treating anything other than a TCL_OK,
TCL_CONTINUE, or TCL_RETURN return code as an "unexpected
return code error".
Beware infinite loops in the -unknown handler:
namespace eval foo {
namespace create -unknown "continue;#"
}
I'd prefer that the -unknown handler be a command prefix,
not a script prefix.

Logged In: YES user_id=79902 Current code (patchfile 59014) corresponds to Revision 2.2 of the TIP. Since I don't understand exactly what I'd do to make use of the TIP90 mechanisms in this context, I'll let someone explain that stuff a bit more first. :^) I'm still not yet 100% sure about the -command handling. I want to write some more tests before committing to a final version. I'm not sure yet about what to do about loops. Or whether a command prefix is really preferable to a script prefix for -unknown. dkf added on 2003-08-20 03:41:18:
