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 element 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 {.*})
