It does this by placing a pseudo-terminal +between the application and the real terminal. It uses the tecla +command-line editing library to read input from the real terminal, +then forwards each just completed input line to the application via +the pseudo-terminal. All output from the application is forwarded +back unchanged to the real terminal. +<P> +Whenever the application stops generating output for more than a tenth +of a second, the <B>enhance</B> 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. +<P> +Note that the user-level command-line editing facilities provided by +the Tecla library are documented in the <B><A HREF="tecla.html">tecla</A>(7)</B> man page +<P> +<A NAME="lbAE"> </A> +<H2>DEFICIENCIES</H2> + +<P> +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 <B>enhance</B> program has +no way of knowing that this has happened, and continues to echo typed +input to its controlling terminal, while the user types their +password. +<P> +Furthermore, before executing the host application, the <B>enhance</B> +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 +previously in force, then subsequently, every time that you enter a +new input line, a duplicate copy will be displayed on the next line. +<P> +<A NAME="lbAF"> </A> +<H2>FILES</H2> + +<PRE> +libtecla.a - The tecla library. +~/.teclarc - The tecla personal customization file. +</PRE> + +<P> +<A NAME="lbAG"> </A> +<H2>SEE ALSO</H2> + +<A HREF="tecla.html">tecla</A>(7), <A HREF="libtecla.html">libtecla</A>(3) +<BR> +<A NAME="lbAH"> </A> +<H2>AUTHOR</H2> + +Martin Shepherd (<A HREF="mailto:mcs@astro.caltech.edu">mcs@astro.caltech.edu</A>) +<P> + +<HR> +<A NAME="index"> </A><H2>Index</H2> +<DL> +<DT><A HREF="#lbAB">NAME</A><DD> +<DT><A HREF="#lbAC">SYNOPSIS</A><DD> +<DT><A HREF="#lbAD">DESCRIPTION</A><DD> +<DT><A HREF="#lbAE">DEFICIENCIES</A><DD> +<DT><A HREF="#lbAF">FILES</A><DD> +<DT><A HREF="#lbAG">SEE ALSO</A><DD> +<DT><A HREF="#lbAH">AUTHOR</A><DD> +</DL> +<HR> +This document was created by +<A HREF="/cgi-bin/man/man2html">man2html</A>, +using the manual pages.<BR> +Time: 22:21:57 GMT, November 09, 2014 +</BODY> +</HTML> |
