It does this by placing a + pseudo-terminal between the application and the real termi- + nal. It uses the tecla command-line editing library to read + input from the real terminal, then forwards each just com- + pleted input line to the application via the pseudo- + terminal. All output from the application is forwarded back + unchanged to the real terminal. + + Whenever the application stops generating output for more + than a tenth of a second, the enhance program treats the + latest incomplete output line as the prompt, and redisplays + any incompleted input line that the user has typed after it. + Note that the small delay, which is imperceptible to the + user, isn't necessary for correct operation of the program. + It is just an optimization, designed to stop the input line + from being redisplayed so often that it slows down output. + + +</pre><h2>DEFICIENCIES</h2><pre> + The one major problem that hasn't been solved yet, is how to + deal with applications that change whether typed input is + echo'd by their controlling terminal. For example, programs + that ask for a password, such as ftp and telnet, temporarily + tell their controlling terminal not to echo what the user + types. Since this request goes to the application side of + the psuedo terminal, the enhance program has no way of know- + ing that this has happened, and continues to echo typed + input to its controlling terminal, while the user types + their password. + + Furthermore, before executing the host application, the + enhance program initially sets the pseudo terminal to noecho + mode, so that everything that it sends to the program + doesn't get redundantly echoed. If a program that switches + to noecho mode explicitly restores echoing afterwards, + rather than restoring the terminal modes that were previ- + ously in force, then subsequently, every time that you enter + a new input line, a duplicate copy will be displayed on the + next line. + + +</pre><h2>FILES</h2><pre> + libtecla.a - The tecla library. + ~/.teclarc - The tecla personal customization file. + + +</pre><h2>SEE ALSO</h2><pre> + <a href="libtecla.html">libtecla(3)</a> + + +</pre><h2>AUTHOR</h2><pre> + Martin Shepherd (mcs@astro.caltech.edu) + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +</pre> +</body> |
