observe - Runtime debugging output in TkCon SYNOPSIS
observe command cmdname ?maxlevel? observe cdelete cmdname observe cinfo cmdname observe variable varname operation ?args? observe vdelete varname operation observe vinfo varname _________________________________________________________________ DESCRIPTION
This command provides runtime debugging output for variables and commands without the need to edit your code. For variables, the underly- ing mechanism uses trace and dump var. For commands, it renames the observed procedure and uses a special wrapper procedure. WARNING: using this procedure after checkpointing state will result in major problems if you clean state because the renamed (true) commands will be lost. This procedure is experimental. Comments are encouraged. observe command cmdname ?maxlevel? This will create a wrapper command which prints out (using dump) the call stack to the console. maxlevel represents the maximum number of levels of the call stack which will be printed (defaults to 4). observe cdelete cmdname Removes the wrapper around an observed command. observe cinfo cmdname Prints out useless info. observe variable varname operation ?args? Currently a wrapper around trace that uses dump to print out the value of the named variable whenever the specified operation on that variable occurs (must be read, write or unset). observe vdelete varname operation Deletes the trace wrapper around the named variable. observe vinfo varname Prints out trace info about the named variable.

dump - Dump information about Tcl interpreter in TkCon SYNOPSIS
dump method ?-nocomplain? ?-filter pattern? ?--? pattern ?pattern ...? _________________________________________________________________ DESCRIPTION
The dump command provides a way for the user to spit out state information about the interpreter in a Tcl readable (and human readable) form. It takes the general form: dump method ?-nocomplain? ?-filter pattern? ?--? pattern ?pattern ...? The patterns represent glob-style patterns (as in string match pattern $str). -nocomplain will prevent dump from throwing an error if no items matched the pattern. -filter is interpreted as appropriate for the method. The various methods are: dump command args Outputs one or more commands. dump procedure args Outputs one or more procs in sourceable form. dump variable args Outputs the values of variables in sourceable form. Recognizes nested arrays. The -filter pattern is used as to filter array ele- ment names and is interepreted as a glob pattern (defaults to {*}). It is passed down for nested arrays. dump widget args Outputs one or more widgets by giving their configuration options. The -filter pattern is used as to filter the config options and is interpreted as a case insensitive regexp pattern (defaults to {.*}). SEE ALSO
