DESCRIPTION
The idebug command provides an interactive debugging environment for
procedures via TkCon. You can place idebug break commands into your
procedure to create breakpoints. It will pop up the TkCon console and
put you into a "debugging" mode. The body, show & trace methods are
intended for internal use only. This procedure works for minimal de-
bugging sessions. Comments are encouraged.
idebug body ?level?
Prints out the body of the command (if it is a procedure) at the
specified level. level defaults to the current level.
idebug break ?id?
Creates a breakpoint within a procedure. This will only trigger
if idebug is on and the id matches the pattern. If so, TkCon
will pop to the front with the prompt changed to an idebug
prompt. You are given the basic ability to observe the call
stack an query/set variables or execute Tcl commands at any
level. A separate history is maintained in debugging mode. To
see the special commands available at the debug prompt, type ?
and hit return.
idebug {echo ?id?} ?args?
Behaves just like echo, but only triggers when idebug is on.
You can specify an optional id to further restrict triggering.
If no id is specified, it defaults to the name of the command in
which the call was made.
idebug id ?id?
Query or set the idebug id. This id is used by other idebug
methods to determine if they should trigger or not. The idebug
id can be a glob pattern and defaults to *.
idebug off
Turns idebug off.
idebug on ?id?
Turns idebug on. If id is specified, it sets the id to it.
idebug {puts ?id?} args
Behaves just like puts, but only triggers when idebug is on.
You can specify an optional id to further restrict triggering.
If no id is specified, it defaults to the name of the command in
which the call was made.
idebug show type ?level? ?VERBOSE?
type must be one of vars, locals or globals. This method will
output the variables/locals/globals present in a particular
level. If VERBOSE is added, then it actually dumps out the val-
ues as well. level defaults to the level in which this method
was called.
idebug trace ?level?
Prints out the stack trace from the specified level up to the
top level. level defaults to the current level.
