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?

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" $* - - Copyright (C)©2003-2004 Harold Levy. - - This code links to the GNU readline library, and as such is bound by the - terms of the GNU General Public License as published by the Free Software - Foundation, either version 2 or (at your option) any later version. - - The GNU General Public License is often shipped with GNU software, and is - generally kept in a file called COPYING or LICENSE.
