This provides lots of useful control over a console: `tkcon attach` interpreter Attaches tkcon to the named interpreter. The name must be that returned by `[tk appname]` or a valid path to a slave interpreter. It's best to use this via the `Console->Attach Console` menu. `tkcon buffer` ?size? Sets or queries the allowed size of the console text widget in lines. The text widget will automatically delete leading lines once this number has been exceeded (read: this is the scroll buffer size). `tkcon bgerror` ?msg errorInfo? Does bgerror stuff in the tkcon master interpreter. `tkcon close` or `tkcon destroy` Destroys this tkcon widget. `tkcon congets` Behaves like the traditional Tcl `gets`, but instead of using `stdin`, it uses the tkcon console window. By default, tkcon replaces the standard gets with this command. This behavior can be controlled by altering the `::tkcon::OPT(gets)` parameter at startup. This should not be called directly - instead rely on the overloaded `gets`, which has support for the optional varName parameter. `tkcon console` args Passes the args to the tkcon text widget (the console). `tkcon error` Pops up a dialog that gives the user a full trace of the last error received in the tkcon console. `tkcon find` string ?-case TCL_BOOLEAN -regexp TCL_BOOLEAN? Highlights all instances of string in the console. If the string is empty, it clears any previous highlighting. `tkcon font` ?fontname? Sets or returns the font used by tkcon text widgets. `tkcon gets` Behaves like the traditional Tcl `gets`, but instead of needing `stdin`, it pops a dialog box up for the user. The overloaded `gets` has support for the optional varName parameter. `tkcon getcommand` A variation of the `congets` method that requires a full command to be input before returning. `tkcon hide` Withdraw the tkcon display from the screen (make sure you have a way to get it back). `tkcon history` ?-newline? Displays the tkcon history in sourceable form. If -newline is specified, it separates each command by an extra newline. `tkcon iconify` Iconifies the tkcon display. `tkcon linelength` ?value? Sets or displays the number that specifies the limit of long result lines. True result is still captured in $_ (and 'puts $_' works). `tkcon load` filename Sources named file into the slave interpreter. If no filename is given, it will attempt to call `tk_getOpenFile` to pop up the file select box. `tkcon main` ?arg arg ...? Passes the args to the main tkcon interpreter to be evaluated and returns the result. `tkcon master` args Passes the args to the master interpreter to be evaluated and returns the result. `tkcon new` Creates a new tkcon widget. `tkcon resultfilter` ?command? Specify a command to process the results before outputting it to the console window. The command receives one argument (the result string) and the string returned is placed in the console. `tkcon save` ?filename ?type?? Saves the console buffer to the given filename. If no filename is given, it will attempt to call `tk_getSaveFile` to pop up the file select box. If no type is given, a dialog will ask you to specify what portion of the text you want to save. `tkcon set` var ?value? Queries or sets a master interpreter variable. `tkcon append` var ?value? Like set, but uses `append` on the variable. `tkcon lappend` var ?value? Like set, but uses `lappend` on the variable. `tkcon show` or `tkcon deiconify` Redisplays tkcon on the screen. `tkcon slave` ?slavename ?arg arg ...?? If called with no args, it returns the name of all the tkcon interpreters. Otherwise given an interp name it passes the args to the named interpreter to be evaluated and returns the result. If no args are passed, then it returns the `[tk appname]` of that interpreter. `tkcon title` ?title? Sets or returns the title for tkcon. `tkcon version` Returns of version of tkcon.
