# Proxy support for retrieving the current version of Tkcon.

# Mon Jun 25 12:19:56 2001 - Pat Thoyts
#
# In your tkcon.cfg or .tkconrc file put your proxy details into the
# `proxy' member of the `PRIV' array. e.g.:
#
# set ::tkcon::PRIV(proxy) wwwproxy:8080
#
# If you want to be prompted for proxy authentication details (eg for
# an NT proxy server) make the second element of this variable non-nil - eg:
#
# set ::tkcon::PRIV(proxy) {wwwproxy:8080 1}
#
# Or you can set the above variable from within tkcon by calling
#
# tkcon master set ::tkcon:PRIV(proxy) wwwproxy:8080

##
## If you set ::tkcon::OPT(exec) to {}, then instead of a multiple
## interp model, you get tkcon operating in the main interp by default.
## This can be useful when attaching to programs that like to operate
## in the main interpter (for example, based on special wish'es).
## You can set this from the command line with -exec ""
## A side effect is that all tkcon command line args will be used
## by the first console only.

## idebug - interactive debugger
#
# idebug body ?level?
#
# Prints out the body of the command (if it is a procedure) at the
# specified level. <i>level</i> defaults to the current level.
#
# idebug break
#
# 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.
#
# idebug echo|{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|{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 'dump's out the
# values 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.

# Here is a group of functions that is only used when Tkcon is
# executed in a safe interpreter. It provides safe versions of
# missing functions. For example:
#
# - "tk appname" returns "tkcon.tcl" but cannot be set
# - "toplevel" is equivalent to 'frame', only it is automatically
# packed.
# - The 'source', 'load', 'open', 'file' and 'exit' functions are
# mapped to corresponding functions in the parent interpreter.
#
# Further on, Tk cannot be really loaded. Still the safe 'load'
# provedes a speciall case. The Tk can be divided into 4 groups,
# that each has a safe handling procedure.
#
# - "::tkcon::SafeItem" handles commands like 'button', 'canvas' ......
# Each of these functions has the window name as first argument.
# - "::tkcon::SafeManage" handles commands like 'pack', 'place', 'grid',
# 'winfo', which can have multiple window names as arguments.
# - "::tkcon::SafeWindow" handles all windows, such as '.'. For every
# window created, a new alias is formed which also is handled by
# this function.
# - Other (e.g. bind, bindtag, image), which need their own function.
