Automatically Starting a Tool

The listing below is a simple example of a ptype declaration that causes the ToolTalk service to automatically start a tool. The example code states:

If a message to display, edit, or compose is received and there is no current instance of the tool running that can handle the message, start “/home/toone/tools/mytest” and deliver the message.

This example causes the ToolTalk service to search indefinitely for a handler.

ptype My_Test {
    start "/home/toone/tools/mytest";
    handle:

	session Display (in Ascii text) => start;
	session Edit (inout Ascii text) => start;
	session Compose (out Ascii text) => start;

	file Display (in Ascii file_name) => start;
	file Edit (inout Ascii file_name) => start;
	file Compose (out Ascii file_name) => start;
};
