-To: chet@po.cwru.edu
-Subject: new readline example
-Message-ID: <14094.12094.527305.199695@mrclean.Stanford.EDU>
-
-Chet,
-
-I've been using readline 4.0. Specifically, I've been using the perl
-version Term::ReadLine::Gnu. It works great.
-
-Anyway, I've been playing around the alternate interface and I wanted
-to contribute a little C program, callback.c, to you that you could
-use as an example of the alternate interface in the /examples
-directory of the readline distribution.
-
-My example shows how, using the alternate interface, you can
-interactively change the prompt (which is very nice imo). Also, I
-point out that you must roll your own terminal setting when using the
-alternate interface because readline depreps (using your parlance) the
-terminal while in the user callback. I try to demostrate what I mean
-with an example. I've included the program below.
-
-To compile, I just put the program in the examples directory and made
-the appropriate changes to the EXECUTABLES and OBJECTS line and added
-an additional target 'callback'.
-
-I compiled on my Sun Solaris2.6 box using Sun's cc.
-
-Let me know what you think.
-
-Jeff

-/* This little examples demonstrates the alternate interface to using readline.
- * In the alternate interface, the user maintains control over program flow and
- * only calls readline when STDIN is readable. Using the alternate interface,
- * you can do anything else while still using readline (like talking to a
- * network or another program) without blocking.
- *
- * Specifically, this program highlights two importants features of the
- * alternate interface. The first is the ability to interactively change the
- * prompt, which can't be done using the regular interface since rl_prompt is
- * read-only.
- *
- * The second feature really highlights a subtle point when using the alternate
- * interface. That is, readline will not alter the terminal when inside your
- * callback handler. So let's so, your callback executes a user command that
- * takes a non-trivial amount of time to complete (seconds). While your
- * executing the command, the user continues to type keystrokes and expects them
- * to be re-echoed on the new prompt when it returns. Unfortunately, the default
- * terminal configuration doesn't do this. After the prompt returns, the user
- * must hit one additional keystroke and then will see all of his previous
- * keystrokes. To illustrate this, compile and run this program. Type "sleep" at
- * the prompt and then type "bar" before the prompt returns (you have 3
- * seconds). Notice how "bar" is re-echoed on the prompt after the prompt
- * returns? This is what you expect to happen. Now comment out the 4 lines below
- * the line that says COMMENT LINE BELOW. Recompile and rerun the program and do
- * the same thing. When the prompt returns, you should not see "bar". Now type
- * "f", see how "barf" magically appears? This behavior is un-expected and not
- * desired.

-Subject: fgets(stdin) --> readline() redirector
-To: chet@po.cwru.edu
-
-Hi Chet,
-
-Here is something you may find useful enough to include in the readline
-distribution. It is a shared library that redirects calls to fgets(stdin)
-to readline() via LD_PRELOAD, and it supports a custom prompt and list of
-command names. Many people have asked me for this file, so I thought I'd
-pass it your way in hope of just including it with readline to begin with.
-
-Best Regards,
-

-/******************************************************************************
-*******************************************************************************
-
- FILE NAME: fgets.c TARGET: libfgets.so
- AUTHOR: Harold Levy VERSION: 1.0
- hlevy@synopsys.com
-
- ABSTRACT: Customize fgets() behavior via LD_PRELOAD in the following ways:
-
- -- If fgets(stdin) is called, redirect to GNU readline() to obtain
- command-line editing, file-name completion, history, etc.
-
- -- A list of commands for command-name completion can be configured by
- setting the environment-variable FGETS_COMMAND_FILE to a file containing
- the list of commands to be used.
-
- -- Command-line editing with readline() works best when the prompt string
- is known; you can set this with the FGETS_PROMPT environment variable.
-
- -- There special strings that libfgets will interpret as internal commands:
-
- _fgets_reset_ reset the command list
-
- _fgets_dump_ dump status
-
- _fgets_debug_ toggle debug messages
-
- HOW TO BUILD: Here are examples of how to build libfgets.so on various
- platforms; you will have to add -I and -L flags to configure access to
- the readline header and library files.
-
- (32-bit builds with gcc)
- AIX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline -ltermcap
- HP-UX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldld -lreadline
- Linux: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline
- SunOS: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lgen -lreadline
-
- (64-bit builds without gcc)
- SunOS: SUNWspro/bin/cc -D_LARGEFILE64_SOURCE=1 -xtarget=ultra -xarch=v9 \
- -KPIC fgets.c -Bdynamic -lc -ldl -lgen -ltermcap -lreadline
-
- HOW TO USE: Different operating systems have different levels of support
- for the LD_PRELOAD concept. The generic method for 32-bit platforms is to
- put libtermcap.so, libfgets.so, and libreadline.so (with absolute paths)
- in the LD_PRELOAD environment variable, and to put their parent directories
- in the LD_LIBRARY_PATH environment variable. Unfortunately there is no
- generic method for 64-bit platforms; e.g. for 64-bit SunOS, you would have
- to build both 32-bit and 64-bit libfgets and libreadline libraries, and
- use the LD_FLAGS_32 and LD_FLAGS_64 environment variables with preload and
- library_path configurations (a mix of 32-bit and 64-bit calls are made under
- 64-bit SunOS).
-
- EXAMPLE WRAPPER: Here is an example shell script wrapper around the
- program "foo" that uses fgets() for command-line input:
-
- #!/bin/csh
- #### replace this with the libtermcap.so directory:
- set dir1 = "/usr/lib"
- #### replace this with the libfgets.so directory:
- set dir2 = "/usr/fgets"
- #### replace this with the libreadline.so directory:
- set dir3 = "/usr/local/lib"
- set lib1 = "${dir1}/libtermcap.so"
- set lib2 = "${dir2}/libfgets.so"
- set lib3 = "${dir3}/libreadline.so"
- if ( "${?LD_PRELOAD}" ) then
- setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}:${LD_PRELOAD}"
- else
- setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}"
- endif
- if ( "${?LD_LIBRARY_PATH}" ) then
- setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}:${LD_LIBRARY_PATH}"
- else
- setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}"
- endif
- setenv FGETS_COMMAND_FILE "${dir2}/foo.commands"
- setenv FGETS_PROMPT "foo> "
- exec "foo" $*

-/* PROBLEMS/TODO:
- *
- * Only tested under Linux; needs to be ported.
- *
- * When running mc -c under the Linux console, mc does not recognize
- * mouse clicks, which mc does when not running under fep.
- *
- * Pasting selected text containing tabs is like hitting the tab character,
- * which invokes readline completion. We don't want this. I don't know
- * if this is fixable without integrating fep into a terminal emulator.
- *
- * Echo suppression is a kludge, but can only be avoided with better kernel
- * support: We need a tty mode to disable "real" echoing, while still
- * letting the inferior think its tty driver to doing echoing.
- * Stevens's book claims SCR$ and BSD4.3+ have TIOCREMOTE.
- *
- * The latest readline may have some hooks we can use to avoid having
- * to back up the prompt.
- *
- * Desirable readline feature: When in cooked no-echo mode (e.g. password),
- * echo characters are they are types with '*', but remove them when done.
- *
- * A synchronous output while we're editing an input line should be
- * inserted in the output view *before* the input line, so that the
- * lines being edited (with the prompt) float at the end of the input.
- *
- * A "page mode" option to emulate more/less behavior: At each page of
- * output, pause for a user command. This required parsing the output
- * to keep track of line lengths. It also requires remembering the
- * output, if we want an option to scroll back, which suggests that
- * this should be integrated with a terminal emulator like xterm.
