Purpose: Discuss extending Tcl functionality
See stacking
Add description of concept of major and minor Tcl commands .
See also Overloading widgets.
What tools are available for extended Tcl commands - say one wanted to add some new minor commands to tcl's info command...
Are these the same as ensembles?
APN Yes, info is a ensemble. To extend with an info time command (for example)
proc info_time {} {return [clock format [clock seconds]]}
namespace ensemble configure ::info -map [dict merge [namespace ensemble configure info -map] {time info_time}]Would you like to rename a function to add a feature?
