___________________________________________________________________________ NAME cmwish - Continuous media programming/windowing shell cmsh - Continuous media programming shell SYNOPSIS cmwish ?options? ?arg arg ...? cmsh ?options? ?arg arg ...? OPTIONS -display display Display (and screen) on which to display window. Only allowed in cmwish. Ignored if -notk is specified. -file fileName Read commands from fileName rather than standard input. The last element in fileName will be used as the title for the application and name of its interpreter for send commands (unless overridden by the -name option). -geometry geometry Initial geometry to use for window. Only allowed in cmwish. Ignored if -notk is specified. -name name Use name as the title to be displayed in the window, and as the name of the interpreter for send commands. Only allowed in cmwish. Ignored if -notk is specified. -sync Execute all X server commands synchronously, so that errors are reported immediately. This will result in much slower execution, but it is useful for debugging. Only allowed in cmwish. Ignored if -notk is specified. -help Print a summary of the command-line options and exit. -nomain Do not connect to the X server. This mode is useful for daemon/server processes. Only available in cmwish ___________________________________________________________________________ DESCRIPTION Cmwish is a simple program consisting of the Tcl command language, the Tk toolkit, the Tcl-DP extension, the CMT extension, and a main program that reads commands from standard input or from a file. It creates a main window and then processes Tcl commands. If cmwish is invoked with no -f option then it reads Tcl commands interactively from standard input. It will continue processing commands until all windows have been deleted or until end-of-file is reached on standard input. Cmsh is a version of cmwish that contains only th Tcl command language, the Tcl-DP extension, the CMT extension, and a main program that reads commands from standard input or from a file. Since it is not linked with the X library or Tk widget set, cmsh is considerably smaller than cmwish and can run without an X server. If there exists | a file .cmrc in the home directory of the user, cmwish (and cmsh) will | evaluate the file as a Tcl script just before reading the first | command from standard input. | If the -file option is provided, then cmwish (or cmsh) reads Tcl commands from the file named in the -file option. These commands will normally create an interactive interface consisting of one or more widgets. When the end of the command file is reached, cmwish will continue to respond to X events until all windows have been deleted. | There is no automatic evaluation of .cmrc in this case, but the script | file can always source it if desired. | VARIABLES Cmwish, and cmsh set the following Tcl variables: argc Contains a count of the number of arg arguments (0 if none), not including the options described above. argv Contains a Tcl list whose elements are the arg arguments (not including the options described above), in order, or an empty string if there are no arg arguments. argv0 Contains fileName if it was specified. Otherwise, | contains the name by which cmwish was invoked. | tcl_interactive | Contains 1 if cmwish is reading commands interactively | (no -file option was specified and standard input is a | terminal-like device), 0 otherwise. | SCRIPT FILES If you create a Tcl script in a file whose first line is #!/usr/local/bin/cmwish -f then you can invoke the script file directly from your shell if you mark it as executable. The same technique can be used for cmsh. If you create a Tcl script in a file whose first line is #!/usr/local/bin/cmwish -nomain -f then you can invoke the script file directly from your shell if you mark it as executable. The examples above assume that cmwish and cmsh have been installed in the default location in /usr/local/bin; if they are installed somewhere else then you'll have to modify the above line to match. PROMPTS When any of the programs are invoked interactively they normally | prompt for each command with ``% ''. You can change the prompt by | setting the variables tcl_prompt1 and tcl_prompt2. If variable | tcl_prompt1 exists then it must consist of a Tcl script to output a | prompt; instead of outputting a prompt cmwish will evaluate the | script in tcl_prompt1. The variable tcl_prompt2 is used in a similar | way when a newline is typed but the current command isn't yet | complete; if tcl_prompt2 isn't set then no prompt is output for | incomplete commands. | KEYWORDS shell, toolkit, Tcl-DP
