## -*- tcl -*-
# ### ### ### ######### ######### #########
## Utility command for use as debug prefix command to un-mangle snit
## and TclOO method calls.
# ### ### ### ######### ######### #########
## Requisites
package require Tcl 8.5
package require debug
namespace eval ::debug {
namespace export caller
namespace ensemble create
}
# ### ### ### ######### ######### #########
## API & Implementation
proc ::debug::caller {args} {
# For snit (type)methods, rework the command line to be more
# legible and in line with what the user would expect. To this end
# we pull the primary command out of the arguments, be it type or
# object, massage the command to match the original (type)method
# name, then resort and expand the words to match the call before
# the snit got its claws into it.

if {[string match ::oo::Obj*::my $m]} {
# TclOO call.
set m [uplevel 1 self]
return [list $m {*}[Filter $a $args]]
}
if {$m eq "my"} {
# TclOO call.
set m [uplevel 1 self]

# for arguments which can be large Tcl values. These would
# screw up formatting and, to add insult to this injury, also
# repeat for each debug output in the same proc, method, etc.
